Quick Bibliography Series Bibliographies in the Quick Bibliography Series of the National Agricultural Library, are intended primarily for current awareness, and as the title of the series implies, are not indepth exhaustive bibliographies on any given subject. However, the citations are a substantial resource for recent investigations on a given topic. They also serve the purpose of bringing the literature of agriculture to the interested user who, in many cases, could not access it by any other means. The bibliographies are derived from computerized on-line searches of the AGRICOLA data base. Timeliness of topic and evidence of extensive interest are the selection criteria.

The author/searcher determines the purpose, length, and search strategy of the Quick Bibliography. Information regarding these is available upon request from the author/searcher.

Animal Models of Disease
1 NAL Call. No.: RC628.A1O2 Abnormalities of plasma lipoproteins in a new genetically obese rat with non- insulin-dependent diabetes mellitus (Wistar fatty rat). Jiao, S.; Matsuzawa, Y.; Matsubara, K.; Kubo, M.; Tokunaga, K.; Odaka, H.; Ikeda, H.; Matsuo, T.; Tarui, S. Basingstoke, Hampshire : The Macmillan Press Ltd; 1991 Jul. International journal of obesity v. 15 (7): p. 487-495; 1991 Jul. Includes references. Language: English Descriptors: Obesity; Diabetes mellitus; Insulin; Cholesterol acyltransferase; Lipoproteins; Apolipoproteins; Blood plasma; Diet; Intestinal absorption; Rats Abstract: We investigated plasma lipoprotein profiles and the activities of tissue cholesterol regulating enzymes in Wistar fatty rats, an animal model for non-insulin-dependent diabetes mellitus (NIDDM). Wistar fatty rats were made by transfer of the fa gene to the Wistar Kyoto rats by backcross-breeding. Wistar fatty and control non-diabetic littermates were given a laboratory chow or an atherogenic diet containing 1 percent (weight percent) cholesterol, 0.5 percent cholic acid, and 5 percent lard. Under the chow diet, plasma fasting glucose and immunoreactive insulin concentrations in Wistar fatty rats were 1.5- and 6- fold higher than controls, respectively. Plasma cholesterol was significantly increased in Wistar fatty rats compared with controls. Elevated plasma cholesterol levels in Wistar fatties was accounted for by the increases of cholesterol content in the d < 1.006 g/ml lipoprotein and high-density lipoproteins. Under the atherogenic diet, plasma cholesterol levels in Wistar fatties were further increased by 129 percent compared with controls. The diet- induced increase of cholesterol contents was shown in all lipoprotein classes for Wistar fatty rats. The activities of regulatory enzymes for cholesterol biosynthesis or absorption were measured in Wistar fatty rats. Both hepatic and intestinal 3-hydroxy-3-methylglutaryl (HMG)-CoA reductase activities were significantly higher in Wistar fatty rats than those in controls (P < 0.05 and P < 0.01, respectively). ACAT activities in Wistar fatties were significantly increased in the intestine (P < 0.05) and decreased in the liver in comparison with controls (P < 0.01). Cholesterol loading caused suppression of HMG-CoA reductase activities and enhancement of ACAT activities of both tissues in Wistar fatty rats as much as in controls. These data suggest that hypercholesterolemia in the NIDDM rats might be attributed to the increases in both de novo synthesis and intestinal absorption of cholesterol.

Wong, M.L.; Licinio, J.; Gold, P.W.; Glowa, J. New York, N.Y. : John Wiley & Sons; 1993 May. The International journal of eating disorders v. 13 (4): p. 399-405; 1993 May. Includes references. Language: English Descriptors: Physical activity; Anorexia; Hypothalamus; Neuropeptides; Gene expression; Rats Abstract: Hypothalamic neuropeptides are thought to contribute to the pathophysiology of eating disorders. In an animal model with chronic abnormalities of energy expenditure, appetitive behavior, and body weight, without acute food restriction, we found alterations in peripheral levels of adrenocorticotropic hormone and corticosterone, but no alterations in the expression of neuropeptides genes that are known to regulate ingestive behavior and food intake acutely. Our data suggest that activation of hypothalamic- pituitary-adrenal function in activity anorexia may not be due to increased transcription of corticotropin-releasing hormone gene, but might be related to posttranscriptional events or to other neuropeptides, such as arginine vasopressin. Furthermore, we suggest that abnormalities in neuropeptides observed in eating disorders may be caused by acute food restriction, rather than by chronic hyperactivity, anorexia, and low weight. 3 NAL Call. No.: 389.8 J824 Acute effects of exercise on food intake in obese and nonobese women. Kissileff, H.R.; Pi-Sunyer, F.X.; Segal, K.; Meltzer, S.; Foelsch, P.A. Baltimore, Md. : American Society for Clinical Nutrition; 1990 Aug. American journal of clinical nutrition v. 52 (2): p. 240-245. charts; 1990 Aug. Includes 29 references. Language: English Descriptors: Appetite; Exercise; Energy expenditure; Food intake; Obesity; Hunger; Satiety; Women Abstract: The animal model of exercise-induced anorexia was employed in humans to develop a laboratory paradigm for studying the acute effect of exercise on food intake. Each of nine obese and nine nonobese women exercised either strenuously (90 W) or moderately (30 W) on a cycle ergometer for 40 min or rested in the laboratory on each of 3 nonconsecutive days. Intake of a liquefied test meal (1.04 kcal/g) eaten 15 min after exercise was significantly less after the strenuous (620 g) than after the moderate (754 g) exercise in the nonobese women but was no different after the two conditions (532 g after strenuous, 581 g after moderate) in the obese women. Heart rate and energy expenditure were increased in proportion to the exercise by the same amount in both groups. The results demonstrate for the first time that food intake is reduced immediately after strenuous exercise in nonobese women, as it is in animals, and validate the feasibility of this laboratory paradigm. 4 NAL Call.

Language: English Descriptors: Amino acids; Bioavailability; Brain disorders; Hyperphenylalaninemia; Child development; Protein metabolism; Protein synthesis; Malnutrition; Neurotransmitters; Serotonin; Animal models; Man Abstract: Inadequacies of the brain's amino acid supply are relevant to the processes of protein accretion and transmitter synthesis during brain development. Experimental hyperphenylalaninaemia has demonstrated the consequences of rather severe imbalances of the brain's amino acid supply. An inadequate supply of essential amino acids has been shown to influence a variety of developmental processes. 9 NAL Call.

Washington, D.C. : American Society for Microbiology; 1993 Feb. Journal of virology v. 67 (2): p. 1086-1089; 1993 Feb. Includes references. Language: English Descriptors: Sheep; Bovine oncovirus; Genetic variation; Structural genes; Viralproteins; Repetitive DNA; Nucleotide sequences; Strain differences; Mutations Abstract: Intradermal injection of a cloned bovine leukemia virus (BLV) provirus (pV344) into sheep allowed direct evaluation of intrastrain variability. A sheep was injected with pV344 DNA mixed with DEAE-dextran and became persistently infected with BLV strain 344. After 18 months, DNA was extracted from peripheral blood leukocytes from a single 0.5-ml blood sample. The long terminal repeat (LTR) and the env gene were amplified by using the polymerase chain reaction, cloned, and sequenced. Nineteen independent LTR clones (0.6-kb inserts) and 16 env clones (1-kb inserts) were analyzed. The in vivo rate of nucleotide change was 0.009%/year (two mutations out of 14,464 bp in 1.5 years), corresponding to only one amino acid change in the env gene. Five point mutations (all transitions), corresponding to a modification rate of 0.034%/year (five mutations out of 9,709 bp in 1.5 years), were identified in the LTR. As a control for Taq DNA polymerase errors, the same procedure using pV344 plasmid DNA was carried out. Out of 9,944 bp sequenced, three point mutations were found (i.e., one misincorporation in 3,315 nucleotides). These data demonstrate the extremely low level (or absence) of intrastrain variability of BLV in vivo. Consequently, BLV persistence in the infected host does not seem to result from an escape mutant strategy, in sharp contrast with the high mutation rates observed in the lentivirus family. The lack of genetic variation supports the possibility of successful vaccine against BLV and probably against the related human T-cell leukemia viruses. 32 NAL Call.

Laboratory animal science v. 40 (1): p. 11-15; 1990 Jan. Includes references. Language: English Descriptors: Dogs; Bone marrow transplant; Models; Human diseases Abstract: Progress in experimental bone marrow transplantation in dogs has provided for the direct transfer of research data to the clinical setting and the therapeutic application of marrow grafting to a variety of human diseases. Animal models of total body irradiation, engraftment and graft-versus-host disease are still needed to solve the existing clinical problems of marrow transplantation. Therefore, work in various canine model systems continues to be of interest. Pet dogs with spontaneously occurring lymphomas are used to study the clinical parameters necessary for applying the technique of transplanting their own marrow (autologous), in conjunction with high dose radiation and/or chemotherapy, to human patients with cancer. A major consideration in the successful transplantation of donor bone marrow (allogeneic) is overcoming histocompatibility barriers to assure engraftment and the prevention of graft-versus-host disease, a major limiting aspect of clinical marrow transplantation. Chemicals, radiation, radiotherapeutic techniques, antisera and monoclonal antibodies have been and continue to be developed in laboratory bred dogs. These approaches suppress the immune system either nonspecifically by ablation of immune reactive tissue, or specifically by affecting certain types of immune reactive cells. Parameters such as clinical effectiveness (engraftment or prevention of graft-versus-host disease), immune reconstitution and undesirable side affects in long-term survivors are all used to determine whether new technology can be transferred from preclinical canine studies to human bone marrow transplantation protocols. 34 NAL Call.

Language: English Descriptors: Obesity; Diet; Weight reduction; Cardiovascular diseases; Heart; Animal models; Rats; Man; Literature reviews Abstract: Obesity is a major risk factor for cardiovascular disease. However, a direct link between these two states is difficult to establish, since obesity frequently occurs with other disease states such as diabetes, hypertension and atherosclerosis. Clinical studies have clearly shown that uncorrected obesity is associated with cardiac hypertrophy and compromised ventricular function. A number of rodent models of obesity have been studied in terms of cardiovascular adaptations. Cardiac function of the obese Zucker rat appears to be normal at a younger age. Only after several months is depression in cardiac function discernable. These animals are mildly hypertensive, but do not exhibit the characteristic increase in cardiac output associated with human obesity. A unique characteristic of JCR:LA-cp rat is that they develop atherosclerotic and myocardial lesions. Hearts from these animals will maintain normal function when perfused with physiological levels of calcium. At higher calcium concentrations, however, mechanical function becomes impaired. Dietary-induced obese rats exhibit many of the hemodynamic alterations associated with human obesity, but there is no evidence to-date that these animals will develop severe cardiac depression. Short-term weight reduction apparently has beneficial cardiovascular effects, but weight cycling may be harmful. Given the widespread occurrence of obesity, further studies are warranted to characterize the cardiac manifestations of this condition. 35 NAL Call. No.: 389.8 J82 The carnitine-deprived newborn rabbit: a potential model to study carnitine deficiency. Penn, D.; Schmidt-Sommerfeld, E. Bethesda, Md. : American Institute of Nutrition; 1988 Dec. The Journal of nutrition v. 118 (12): p. 1535-1539; 1988 Dec. Includes 34 references. Language: English Descriptors: Nutrient deficiencies; Carnitine; Neonates; Rabbits Abstract: This report describes the novel development of an animal model for neonatal carnitine deficiency using the artificially fed newborn rabbit. Each litter was separated from the mother following the first colostrum feeding and divided into 2 groups, one of which was fed a purified rabbit formula that was essentially free of carnitine; the other received the same formula supplemented with L-carnitine (100 mg/l). At 9-13 d of age, rabbit pups receiving the carnitine-free formula had lower concentrations of total, free and acylcarnitine in plasma and urine, as well as lower total acid soluble carnitine concentrations in liver, muscle, heart and brown adipose tissue than those receiving the same formula supplemented with L-carnitine. Their plasma and tissue levels were also lower, but their urinary carnitine concentrations were higher than those in naturally-raised pups. The findings suggest that the described animal model may prove to be a useful tool for the investigation of certain aspects of neonatal carnitine deficiency. 36 NAL Call.

Includes references. Language: English Descriptors: Diet; Carotenoids; Carcinoma; Disease prevention Abstract: As evidence accumulated from epidemiological studies that beta- carotene acts as a chemopreventive agent with respect to inhibiting the appearance of certain types of tumors in humans, attention focused on animal models as a means of extending our understanding of carotenoid function. Unfortunately, most animals used in research are "white fat" animals, and require large amounts of carotenoids in their diets to obtain significant blood and tissue levels. Even with these limitations, beta-carotene, a provitamin A carotenoid, as well as canthaxanthin, a nonprovitamin A carotenoid, have been shown to protect animals against UV-induced skin tumors, UV and carcinogen- induced tumors, and carcinogen treatment alone. Similar observations have been made in cell and organ cultures where carotenoids have been shown to prevent malignant transformation and nuclear damage. Although the mechanism of this protection is still unclear, the evidence continues to accumulate that carotenoids may possess intrinsic chemopreventive action with respect to tumor formation. 37 NAL Call.

Language: English Descriptors: Mice; Mutants; Disease models; Nephrotic syndrome; Glomerulonephritis; Histopathology Abstract: Spontaneous nephrotic mice (ICGN mice), a new mutant strain of mouse from outbred ICR, were clinically, macroscopically, histologically and immunohistochemically studies to establish their value as a model for human nephrotic syndrome. Most of the affected mice developed proteinuria, hypoproteinaemia and hypercholesterolaemia, and some of them developed systemic oedema. A high concentration of blood urea nitrogen (BUN) and a low haematocrit value were also observed. The kidneys of severe cases showed a decrease in size and had a yellowish granular surface. These findings indicated that the mice were terminally affected by chronic of renal insufficiency. Histopathology demonstrated glomerular lesions consisting of thickened basement membranes of the capillary loops with irregular spike-like protrusions and enlargement of the mesangium unaccompanied by cellular proliferation. The immunofluorescence technique revealed positive granular staining for IgA, IgG and IgM and to a lesser extent for C3 along the capillary loops in affected mice. The similarity between this spontaneous disease and human nephrotic syndrome caused by idiopathic glomerular lesions is discussed. ICGN mice may be a useful animal model for this human disease. 40 NAL Call. No.: QL55.A1L3 Characterization of acute and latent herpes simplex virus infection of dorsal root ganglia in rats.

Language: English Descriptors: Rats; Herpes simplex virus; Ganglia; Acute infections; Latent infections; Animal models; Experimental infections; Subcutaneous injection; Feet Abstract: The characteristics of HSV type-1 infection following subcutaneous inoculation in the dorsum of one hind paw of Sprague-Dawley rats were studied to determine whether infection in rats might more closely parallel the infection in man than is seen in other animals. The serologic and virologic characteristics of acute and latent ganglion infection conformed to those of human infection. Immunohistochemical studies suggested that sensory ganglion infection arose via centripetal axonal migration of virus as is hypothesized in man. In rat, small type B neuronal cell bodies appeared central to the maintenance of latent infection and reactivation observed during cocultivation of lumbar ganglia. Acute and latent lumbar sensory ganglion infection in rats after subcutaneous hind paw injection of HSV-1 appears to be another suitable model of this infection in man. 41 NAL Call.

Includes references. Language: English Descriptors: Rats; Animal models; Disease models; Neoplasms; Lungs; Radiography; Monitoring Abstract: Roentgenographic techniques were investigated for imaging orthotopic tung tumours in anaesthetized nude rats endobronchially implanted with human lung cancer cells. A conventional radiographic unit with a dual-screen, double- emulsion film mammographic receptor produced images preferable to those from a mammographic unit because of superior resolution. Typical exposure factors were 300 mA, 29 kVp, and 17 ms at a focus-film distance of 76 cm with a 2.11 by 2.41 mm effective focal spot and inherent filtration of 1.2 mm aluminium. Sensitivity for tumour detection was 0.93 for 59 animals with pathologically proved tumours and 0.96 for 54 animals with tumours larger than 4 mm or 50 mg. For 24 pathologically tumour-free animals, specificity was 1-00. For 55 animals radiographically judged to have tumours, positive predictive value was 1.00. For all 83 animals, accuracy was 0.95. This technique effectively demonstrates orthotopic human lung tumours in nude rats and should be useful for noninvasive monitoring of tumour presence, location, size, and changes in size. 42 NAL Call.

Language: English Descriptors: Chlorpyrifos; Nervous system diseases; Neurotoxins; Acetylcholinesterase; Esterases; Pharmacokinetics; Brain; Man; Fowls; Hens Abstract: Chlorpyrifos [0,0-diethyl 0-(3,5,6-trichloro-pyridyl) phosphorothioate] caused delayed polyneuropathy in man. Contrary to previous studies, we report here that it also causes delayed polyneuropathy in the hen, the animal model for this toxicity. The minimal neuropathic dose was 60-90 mg/kg p.o., corresponding to 4-6 times the estimated LD50. Consequently, pralidoxime (2-PAM) in conjunction with atropine was necessary to reverse acetylcholinesterase AChE) inhibition and cholinergic toxicity in hens given high enough doses of chlorpyrifos to cause neuropathy. Chlorpyrifos was slowly absorbed after single oral doses and the threshold of inhibition (>70%) of neuropathy target esterase (NTE), the putative target for delayed neuropathy, was reached within 5-6 days. High AChE inhibition (>90%), however, was measured within hours after dosing because of the higher potency of chlorpyrifos to inhibit this enzyme. In vitro studies showed that chlorpyrifos-oxon, the active metabolite of chlorpyrifos, was 10-20 times more active against AChE than against NTE, confirming the clinical observation. No differences were seen between human and hen enzymes in this respect. Hen and human brain homogenates contain A-esterases which hydrolysed chlorpyrifos to about the same extent in both species. In conclusion, chlorpyrifos causes delayed polyneuropathy in the hen, as was reported in man. The reasons for previous negative data in the hen are probably due to the relatively lower doses which were used. Judging from in vitro studies with hen and human enzymes, there are no differences in the two species as far as their relative sensitivity to delayed polyneuropathy. It is likely that delayed polyneuropathy would develop in both species only after severe cholinergic toxicity requiring aggressive antidotal treatment. 44 NAL Call.

Language: English Descriptors: Livestock; Man; Lentivirinae; Oncovirinae; Disease transmission; Spread; Pathogenesis; Host specificity; Viral diseases; Disease models; Literature reviews; Animal models Abstract: Retrovial infections of livestock have become of increasing importance due to their usefulness as comparative models for human retroviral infections and their effects upon animal health and marketability of animals and animal products nationally and internationally. This paper presents a perspective on the retroviruses of economic concern in veterinary medicine with emphasis on the importance of understanding the modes of virus transmission and the species specificity of the viruses. The retroviruses reviewed include the oncovirus, bovine leukosis virus, and the lentiviruses, equine infectious anemia virus; maedi/visna virus, caprine arthritis-encephalitis virus and bovine visna-like virus. The comparative features amongst these animal retroviruses and those of humans must be recognized by the veterinary and medical professions since the similarities in virus replication and spread by blood transfer can provide important clues in controlling and perhaps preventing human retroviruses infections, such as the human immunodeficiency virus. 49 NAL Call.

Language: English Descriptors: Haemophilus; Virulence; Serotypes; Strain differences; Guinea pigs; Intraperitoneal injection; Application methods; Morbidity; Mortality; Disease models Abstract: Reference strains for Haemophilus parasuis serovars 1 to 7 were examined for virulence by inoculation of guinea pigs. Guinea pig response to intraperitoneal inoculation was similar for the 7 reference strains. However, apparent differences in virulence were detected after intratracheal inoculation. Cells of the reference strains for serovars 1 and 5 were most invasive, causing moribundity or death at higher doses and a persistent septicemia at lower doses. Haemophilus parasuis could be isolated from respiratory and systemic sites; purulent bronchopneumonia, pericarditis, and pleuritis were apparent in infected guinea pigs. Inoculation of cells of the reference strains for serovars 2 and 6 also resulted in bronchopneumonia and moribundity or death in some guinea pigs; however, reisolation of H parasuis and microscopic lesions at necropsy were less pronounced than those observed with serovars 1 and 5. Inoculation of cells of serovars 3, 4, and 7 induced only transient clinical signs and minimal evidence of H parasuis infection at necropsy. The data from intratracheal inoculation of guinea pigs are similar to data from other investigations in swine, indicating differences in the pathogenic potential of H parasuis strains. Thus, guinea pigs may be useful as a laboratory animal model for examining cellular factors associated with virulence and immunogenicity of H parasuis. 50 NAL Call.

Language: English Descriptors: Rats; Diabetes; Animal models; Hematology; Normal values; Blood sugar; Hemoglobin; Glycerate 2,3-bis(phosphate) Abstract: Hematologic values are compared for normal and streptozotocin-induced diabetic rats after 6 weeks of induced diabetes. Most hematologic parameters were the same in the two groups except for blood glucose, glycated hemoglobin, and 2,3 diphosphoglycerate, all of which were elevated in the streptozotocin group. However the P50 (the P02 at which the oxygen-carrying capacity of blood is 50% of maximal) remained normal. We hypothesize that a left shift in the oxyhemoglobin dissociation curve caused by the glycation of a small percentage of the hemoglobin is compensated by elevation in the 2,3-diphosphoglycerate which returns the P50 to normal values. This compensatory mechanism also occurs in some stages of human diabetes. 51 NAL Call.

Language: English Descriptors: Mice; Animal models; Convulsions; Aging Abstract: Senescence-accelerated mice (SAM) are one of the animal models used for studying senescence, which consist of several substrains such as SAM-R/1, R/2, P/1, P/2. SAM-R/1/Eis maintained in Eisai Tsukuba Research Laboratories, Ibaraki, Japan, was originally introduced as a substrain of a normal control SAM-R/1 from Kyoto University, Japan. We have noted signs of convulsions in SAM-R/1/Eis mice during routine animal care, particularly while changing cages. We identified the clinical signs and determined the concentrations of glucose and immunoreactive insulin in plasma of SAM-R/1/Eis mice. There were no differences in the male:female ratios of mice showing prodrome only, grand mal, or no-signs. The ages at which prodrome and grand mal were first noted peaked between 20 and 25 weeks. Concentrations of glucose and immunoreactive insulin in plasma did not indicate the mice were in insulin hypoglycemia, which is one cause of convulsions. AKR strain mice, some of which originated with the SAM strain are known to become convulsive by repeated "throwing" stimulations. Conversely, in SAM-R/1/Eis, throwing stimuli are not needed to cause convulsive signs. Thus it is likely that in SAM-R/1/Eis mice the signs are triggered by repeating mild environmental changes, such as changing cages. The results of this study show that SAM-R/1/Eis is neither a normal control strain, nor an original SAM-R/1 strain. But it is possible that SAM-R/1/Eis is another useful animal model for studying spontaneous convulsion. 54 NAL Call.

However, the suggestion of an inverse relationship between breast- feeding and IDDM based on epidemiological studies, remains controversial. There is a significant positive correlation between consumption of unfermented milk protein and incidence of IDDM in data from various countries. Conversely, a possible negative relationship is observed between breastfeeding at age 3 mo and IDDM risk. Diet may be an important permissive factor in the development of IDDM. 55 NAL Call.

The subunit proportions (L:M:C) of the PFK isozymes from normal adult erythrocytes were 2:86:12. Affected adult erythrocyte 6-phosphofructo-1- kinase (PFK) isozymes contained normal L-type (31%) and C-type (61%) subunits as well as a small amount (8%) of truncated M-type subunit. 2. When measured within 24 hr of birth, both normal and affected dog erythrocytes contained high PFK activities due to elevated levels of the L-type subunit. As the dogs matured, PFK activity decreased due to a greater than 99% loss of the L-type subunit. 3. By 2 weeks of age, the M-type and C-type subunits in normal dog PFK isozymes increased severalfold and attained near adult levels. 4. During post- natal development, the L-type subunit from affected dog erythrocytes decreased more rapidly than from normal dog erythrocytes; but it was maintained at a higher level in the affected adult erythrocytes. Also, in the affected dog erythrocytes, truncated M-type subunits were detected; and the initially high levels of the C-type subunit decreased approximately 50% after 4 weeks. 60 NAL Call.

Includes references. Language: English Descriptors: Obesity; Hypertension; Blood pressure; Heart rate; Stress; Diet; Body weight; Cycling; Angiotensin; Animal models; Rats Abstract: The present study was designed to reproduce the mild hypertension seen in dietary obese weight-cycled rats [P. Ernsberger and D. 0. Nelson. Am. J. Physiol. 254 (Regulatory Integrative Comp. Physiol 23): R47-R55, 1988] and determine whether this mild hypertension was associated with changes in sodium excretion and pressor responsiveness to angiotensin II (ANG II). Male Sprague- Dawley rats were fed pelleted chow (Pellet group) or chow plus sweetened condensed milk (Milk group) or were exposed to four cycles of a 4-day fast alternated with 2 wk of refeeding of pelleted chow and sweetened condensed milk (Cycled group). Blood pressure and heart rate were measured by tail cuff at the onset and last day of each fast and after 3 days of refeeding. During fasting, urine sodium excretion was measured. Mean arterial pressure and heart rate responses to intravenous administration of ANG II (40, 80, and 120 ng/kg), metoprolol (1 mg/kg), and methyl scopolamine (2 mg/kg) were obtained from the femoral artery in awake unrestrained rats. Weight cycling did not lead to mild hypertension or increased bradycardic response to sympathetic blockade with metoprolol. ANG II-elicited pressor responses were similar for Pellet, Milk, and Cycled groups. Sodium excretion did not change with fasting. Mild hypertension developed when obese weight-cycled rats were housed together in groups and not when housed individually. Our preliminary data are consistent with the notion that stress associated with group housing may be a factor in the mild hypertension of obese weight-cycled rats. 68 NAL Call.

Nutrition research v. 10 (8): p. 915-928; 1990 Aug. Includes references. Language: English Descriptors: Ethanol; Mammary gland neoplasms; Carcinogens; Rats Abstract: Epidemiological evidence indicates that ingestion of alcoholic beverages is a risk factor or is associated with a risk factor for breast cancer. A small increase in relative risk (1.1-1.2) compared to non-drinkers, has been reported for drinkers of small amounts of alcohol, approximately 3-4 drinks per week; a larger increase in relative risk (1.4-1.7) with a significant dose relationship occurs at intakes of 2-3 drinks per day. Two drinks per day would supply approximately 7-10% of a woman's caloric intake. This evidence, coupled with the general association of breast cancer risk with higher economic, nutritional and education status, supports the view that relevant animal models for study of the relationship between alcohol and breast cancer should employ moderate alcohol and good nutrient intake. Two carcinogenesis experiments were performed in ethanol-fed, female, Sprague- Dawley rats. In the first, groups of 50 rats were fed control diet ad libitum (CON) or were fed the diet with 20% of calories supplied as ethanol (ETOH) or were pair-fed control diet in amounts determined by the intake of ETOH rats (PF). They were given 7,12-dimethylbenzanthracene (DMBA), 20 mg/kg, by gavage at 55 days of age and monitored for tumor development. There was no detectable effect of ethanol on mammary tumor latency, incidence, number, weight or histology. In the second experiment, rats divided into the same groups were given 25% of calories as ethanol, with occasional increases to 35%, and the dose of DMBA was increased to 30 mg/kg. Again, there was no detectable effect of ethanol on mammary tumorigenesis. Thus, no effect of ethanol on mammary gland tumorigenesis by DMBA was observed in rats treated by 2 different protocols. 70 NAL Call.

Language: English Descriptors: Dogs; Hepatitis; Disease models; Animal models; N- nitrosodimethylamine Abstract: A model of toxin-induced progressive hepatitis is described in Beagles. The toxin, dimethylnitrosamine, was administered orally to 18 Beagles; 6 dogs comprised a control group. Clinical signs and laboratory test results were monitored as disease progressed and were used to determine the end point of disease. Following euthanasia, histologic lesions were scored and used to derive a total severity score for each dog. Severity scores were then used to allot the 18 dogs to 3 groups of hepatic disease, defined as mild, moderate, or severe. Changes in clinical laboratory test results, including tests of hepatic function, and clinical signs indicative of liver disease were described chronologically for all dogs. Group means of clinical laboratory test results and quantifiable clinical signs (eg, weight loss and ascitic fluid accumulation) were compared. This model offers several advantages, compared with other experimental models of canine hepatic disease. These include hepatospecificity, similarity to natural disease (eg, the development of multiple extrahepatic portosystemic shunts), and the ability to titrate the disease to a desired end point. The major disadvantages of this model were the toxic nature of the drug to human beings and the variation in individual animal response to the toxin, which precludes preassignment of animals into groups. 71 NAL Call.

Language: English Descriptors: Fowls; Line differences; Antibody formation; Animal models; Heritability; Selection responses; Genetic trend; Selection differential; Breeding value; Phenotypes Abstract: With the aim of improving general disease resistance, chickens were divergently selected for their antibody titers 5 d after immunization with sheep red blood cells for nine generations. Selected and control lines differed significantly for primary and secondary responses after three generations. Heritability of the antibody titer was estimated by REML fitting an animal model using a derivative-free algorithm. The heritability estimate using data on all lines simultaneously was .31. Realized heritability of the antibody titer in the selected lines was estimated by using either the phenotypic cumulative response as the deviation from the control line or the mean breeding values obtained with an animal model. Values from the two methods were consistent, giving a realized heritability of .21 and .25 in the high and low lines, respectively. The genetic trend was not linear and the response to selection tended to accelerate over generations. 72 NAL Call.

Flies grown without adenine served as LXD-controls. Purines ranked as follows; adenine > adenosine > AMP > inosine > IMP in decreasing order of toxicity to LXD-adenine flies. Addition of ribose to 9N position, or phosphate or carboxy to 6C position of the purine ring alleviated the toxicity.

Includes references. Language: English Descriptors: Dietary fat; Soybean oil; Olive oil; Triolein; Unsaturated fatty acids; Antioxidants; Lipid peroxidation; Low density lipoprotein; Verylow density lipoprotein; Blood lipids; Blood plasma; Rats Abstract: In order to investigate the influence of fatty acid pattern and antioxidants other than vitamin E on lipid peroxidation and antioxidant levels of plasma very low density and low density lipoproteins (VLDL + LDL), the effects of three diets (equalized for vitamin E) containing soybean oil, olive oil, or an oleate-rich mixture of triglycerides (triolein) were studied in rats. A significantly lower concentration of thiobarbituric acid-reactive substances (TBA-RS) in plasma and lipoproteins was found after the olive oil diet (soybean oil, 3.7 +/- 0.4 nmol/ml; triolein, 2.1 +/- 0.5 nmol/ml; olive oil, 1.5 +/- 0.3 nmol/ml, in plasma) (soybean oil, 0.99 +/- 0.16 nmol/ml; triolein, 0.96 +/- 0.13 nmol/ml; olive oil, 0.38 +/- 0.12 nmol/ml, in the VLDL + LDL fraction). Furthermore, the results from in vitro copper-induced lipid peroxidation, expressed in terms of conjugated dienes, lipid hydroperoxides, and TBA-RS content, showed that VLDL + LDL particles from olive oil-fed rats were remarkably resistant to oxidative modification. The results suggest that the fatty acid unsaturation of dietary oils is not the only determining factor of the antioxidant capacity of lipoproteins in this animal model. The maximal protection observed after the olive oil diet may be explained by the presence of other unidentified antioxidants in addition to vitamin E, derived from oil intake. Therefore, the optimal balance between the content of unsaturated fatty acids and natural antioxidants in dietary oils appears to be of major importance. 74 NAL Call.

Language: English Descriptors: Cholecalciferol; Vitamin d; Metabolites; Osteoporosis; Bone density; Calcium; Mineral supplements; Ovariectomy; Rats; Quails Abstract: Degenerative bone conditions such as osteoporosis affect the elderly population by causing skeletal fractures. The incidence of osteoporosis is far greater in postmenopausal women and therefore, loss of ovarian function, leading to estrogen deficiency, plays an important role in the development of this disease. Abnormal vitamin D metabolism and insufficient dietary calcium may also contribute to the development of osteoporosis. Three experiments were conducted to investigate the effects of estrogen supplementation and dietary vitamin D3 steroids or calcium supplementation on skeletal metabolism. Eight week old ovariectomized (Ovx) or sham operated Sprague-Dawley rats or aged anovulatory Coturnix quail hens were used as animal models. Feeding a diet containing 1,25(OH)2D3 (5 microgram/kg) with 0.2% calcium was as effective in maintaining bone mineral concentrations as 20 microgram/kg vitamin D3 and 1.0% calcium. However, both bone calcium and zinc concentrations were decreased in Ovx rats and anovulatory quail fed 1,25(OH)2D3 and low calcium. Estrogen supplementation to Ovx rats and anovulatory quail fed 1,25(OH)2D3 and 0.2% Ca increased mineral concentrations, thus suggesting enhanced skeletal integrity. Therefore, these studies suggest improved skeletal calcification in control and estrogen supplemented female rats and quail fed 1,25(OH)2D3 and 0.2% calcium versus vitamin D3 with 1.0% calcium. 76 NAL Call.

Language: English Descriptors: Zinc; Infant formulas; Soy milk; Phytate; Intestinal absorption; Neonates; Rhesus monkeys; Rats Abstract: Low zinc bioavailability from soy formula may be the result of the formula's phytate content. We assessed the effect of phytate removal from soy formula on Zn absorption using infant rhesus monkeys and suckling rat pups as animal models. Zn absorption in monkeys, as determined by whole-body counting, was 65% from human milk, 54% from monkey milk, 60% from whey-predominant formula, 46% from casein-predominant formula, and only 27% from conventional soy formula (0.621 mmol phytate/L). In contrast, Zn absorption from dephytinized soy formula (0.067 mmol phytate/L) was 45%. In suckling rats, Zn absorption from conventional soy formula was only 16% vs 47% from dephytinized soy formula. Phytate concentration in a variety of experimental soy formulas was inversely correlated to Zn absorption. These results suggest that the low bioavailability of Zn from soy formula is a function of its phytate concentration and can be overcome by the removal of phytate. 77 NAL Call.

Language: English Descriptors: Diabetes mellitus; Hypercholesterolemia; Drug therapy; Blood serum; Cholesterol; Rabbits Abstract: Diabetes mellitus is associated with hyperlipidemia and increased risk of atherosclerosis. A diabetic animal model has been developed to study the effect of treatment with pravastatin, a potent HMG CoA reductase inhibitor, on plasma lipoprotein levels. Hypercholesterolemia was induced in alloxan diabetic and control rabbits by feeding a diet containing 25% casein and 10% hydrogenated coconut oil for 8 weeks. Feeding the casein-coconut oil diet to the diabetic group resulted in a 5-fold increase in serum cholesterol levels, which was not statistically different from the nondiabetic group fed this diet. However, in the diabetic group, there was more cholesterol in the VLDL fraction and less in LDL as compared to the nondiabetic group. Serum triacylglycerol levels in the diabetic rabbits were variable and ranged from 58-943 mg/dl. The diabetic and nondiabetic animals were then treated with pravastatin at a dose of 10 mg/kg per day for 21 days. In the nondiabetic group, pravastatin treatment significantly lowered serum and LDL cholesterol concentrations by 28.5% (52.3 mg/dl, P < 0.05) and 36.2% (40.7 mg/dl, P < 0.05) respectively, relative to the placebo group. Serum and VLDL triacylglycerol levels in the nondiabetic group were also significantly decreased following pravastatin treatment. In the diabetic group, serum and LDL cholesterol levels were decreased by 37.0% (69.1 mg/dl, P < 0.05) and 52.7% (32.1 mg/dl, P < 0.01), respectively, relative to the diabetics given the placebo. Pravastatin treatment did not adversely affect serum glucose levels. Thus, pravastatin treatment was effective in controlling the hypercholesterolemia present in these diabetic animals. 78 NAL Call.

Language: English Descriptors: Dietary fat; Mammary gland neoplasms; Incidence; Mice Abstract: The relationship between dietary fat consumption and the incidence of breast cancer, if any, needs to be quantified so that dietary guidelines can be issued for the prevention of breast cancer. Frequently, only two widely different dietary fat levels, often differing in essential fatty acid content, have been compared in animal models. Moreover, the latent period in common animal models for breast cancer is very short and does not reflect the relatively long latent periods in human breast cancer. We describe a study with BALB/c-MTV mice, a strain with a high average tumor incidence and a latent period of over 60 weeks on average. The mice were fed diets with fat levels ranging from 10% to 40% of energy, in which fat was isocalorically substituted for carbohydrates. The level of linoleic acid in these diets was kept constant al 6.5% of energy. Both the mean tumor incidence and latent periods of the groups fed diets with 10-16% of energy as fat were not significantly different from each other. There were also no differences between these parameters in the groups fed 22-40% of energy as fat. However, the mean incidence and latent period of the groups fed 22% or more of energy as fat was significantly higher than that of the groups fed less fat. We conclude that above about 22 % of energy, fat does not influence the incidence and latent period of mammary tumors in BALB/c-MTV mice. 80 NAL Call.

As determined from differences in the mean number of cryptosporidial developmental stages per villus in treated vs control rats, arprinocid had a substantial effect on cryptosporidial activity, which was parasitistatic instead of parasiticidal. Drug-ranging experiments indicated that arprinocid was effective at 50 and 25 mg/kg/d, but not at 12.5 mg/kg/d. These results suggest that further testing of arprinocid in different animal models, or in phase-I clinical trials, is warranted. 81 NAL Call.

Includes references. Language: English Descriptors: Rats; Hepatitis; Vitamin e; Animal models Abstract: Long-Evans Cinnamon (LEC) rats are autosomal recessive mutants that develop hepatitis and hepatocellular carcinoma. Because copper accumulates in the livers of these rats, and some of their clinical and pathological features are similar to those of patients with Wilson's disease, LEC rats are proposed as an animal model of Wilson's disease. It has been thought that unbound copper generates free radicals, which act as hemolytic and hepatocytotoxic agents. To examine the effects of vitamin E as an antioxidant on hereditary hepatitis in LEC rats, we fed 3-week-old rats for 25 weeks either vitamin E-deficient, control, or vitamin E-supplemented diets which contained < 0.1 mg of total tocopherols, 2 mg of d,l-alpha-tocopheryl acetate (2 I.U.), and 58.5 mg of d,l- alpha-tocopheryl nicotinate (50 I.U.), respectively, per 100 mg of feed. In males, body weight loss was first observed in the vitamin E-deficient group, and mean ages at which jaundice occurred were in the order: deficient younger than control younger than supplemented groups. The ages when plasma glutamic oxaloacetic transaminase and glutamic pyruvic transaminase activities began to increase sharply and peaked followed the same order. Thus, it is likely that free radicals are involved in jaundice and hepatitis in LEC male rats, and they are a model for studying the relationship of copper, free radicals, and hepatitis. Conversely, in females, no apparent differences in clinical and biochemical changes were observed among the three groups. Causes for the discrepancy between the sexes remain to be clarified. 82 NAL Call.

Renal phospholipid and triglyceride fatty acid compositions were markedly altered by dietary treatment: 20:5n-3 and 22:6n-3 levels were elevated in the kidneys from mice fed fish oil at the expense of 18:2n-6 and arachidonic acid, 20:4n-6. Despite these lipid alterations, however, survival and proteinuria were not improved by long term fish oil consumption in mice with polycystic kidney disease. 83 NAL Call.

Language: English Descriptors: Obesity; Maternal nutrition; Fasting; Metabolism; Hypoglycemia; Weight gain; Pregnancy; Eating patterns; Neonates; Rats Abstract: Maternal obesity is a risk factor for subsequent fasting hypoglycemia in human infants after birth. To investigate further this problem, we employed an animal model of obesity to study neonatal extrauterine metabolic adaptations in pups of obese and lean rats. Female Sprague-Dawley rats were fed a 'cafeteria diet' to induce obesity prior to and during pregnancy. Prior to mating, the cafeteria fed rats were significantly heavier (449 v. 345 g, P < 0.001) than the controls. Furthermore, weight gain during pregnancy and weight at term were also significantly greater in the obese rats even though they consumed less food during pregnancy. Pup weights and the number of pups per litter were similar between the two groups. Pups born to obese mothers demonstrated hypoglycemia after being fasted for 150 and 180 min when compared with control pups. Hepatic glycogen stores were increased in the fetus of pups born to obese mothers. Glycogen content in pups born to obese mothers declined minimally after birth and remained greater than hepatic glycogen values in control pups throughout the study. In addition to increased fetal storage of glycogen, fetal hepatic triglyceride content was augmented in pups of obese rats. These triglyceride stores declined and were mobilized during fasting after birth. In contrast, hepatic triglyceride content increased after birth among control rats. These results suggest that maternal obesity results in augmented fetal hepatic tissue stores of both glycogen and triglycerides. Hypoglycemia among pups of excessively obese mothers may be due to attenuated mobilization of hepatic glycogen. Alternate fuel utilization as evident by the mobilization (rather than storage) of hepatic triglycerides may contribute to energy metabolism during periods of hypoglycemia. 86 NAL Call.

Language: English Descriptors: Sri lanka; Maize oil; Coconut oil; Diet; Blood lipids; Cholesterol; Triglycerides; High density lipoprotein; Low density lipoprotein; Young adults; Men Abstract: Young, healthy individuals living in Sri Lanka often consume a diet containing coconut oil as their main source of fat. Blood lipid values and selected platelet related factors have been measured in a group of 16 free living young adults, ages 16 to 21, before and 8 weeks after they had been shifted from their usual diet to a similar one in which the coconut oil was replaced by whole milk powder and corn oil. The results indicate that their blood cholesterol, cholesteryl ester, and several other related circulating blood lipid values, as well as the platelet factor 4 values, were elevated prior to the diet change. Many of these factors, associated as risk factors for atherogenesis, were substantially reduced at the end of the diet change. The only plasma components which were altered substantially were the triglycerides and the HDL cholesterol. These results suggest that the special atherogenic effects of coconut oil that have been demonstrated in so many animal models may be similarly active in humans. 87 NAL Call.

Language: English Descriptors: Rats; Disease models; Sex hormones; Hepatitis Abstract: LEC rats, which have hereditary hepatitis and have recently been proposed as an animal model for Wilson's disease, were examined to determine the effects of sex hormones on fulminant hepatitis. After the rats had undergone ovariectomies or orchidectomies (castration) and were compared with intact rats, the age at the onset of fulminant hepatitis was not substantially altered but the survival rates decreased from 50% to 12.5% for females and 75% to 14.3% for males, indicating that sex hormones did not influence the occurrence of fulminant hepatitis but influenced mortality due to fulminant hepatitis. When testosterone was administered to the ovariectomized or orchidectomized rats, the survival rate increased to over 90% in both sexes. In contrast, estradiol did not affect the survival rate of either sex but affected the onset of fulminant hepatitis. That is, with the administration of estradiol, the age at which serum GPT activity reached its maximum was delayed 4 weeks in ovariectomized rats and 6 weeks in orchidectomized rats as compared with intact rats. A similar but somewhat weaker tendency appeared in rats given progesterone. The results of our study indicate that sex hormones have no effect on the rate of occurrence of hepatitis but affect the progression of hepatitis. In particular, testosterone increased the survival rate of rats with fulminant hepatitis, and exogenous estradiol delayed the onset of hepatitis for several weeks. 88 NAL Call.

Language: English Descriptors: Louisiana; Dogs; Trypanosoma cruzi; Trypanosomiasis; Cardiomyopathy; Disease models; Electrocardiograms; Recordings; Disease course; Animal models Abstract: Purebred Beagles were inoculated with Trypanosoma cruzi isolates from a North American opossum or armadillo (Tc-W), and dog (Tc-D). Although Tc- D established infection in dogs, the dogs did not develop cardiac abnormalities. Dogs inoculated with Tc-W developed acute myocarditis associated with increases in P-R interval, atrioventricular block, depression of R wave amplitude and shifts in mean electrical axis. Echocardiograms were normal during this stage. Three Tc-W-inoculated dogs died during the acute stage. Following the acute stage, 5 of 8 Tc-W-inoculated dogs entered an indeterminate stage in which ECG changes were minor and echocardiograms were normal. Progression to the chronic stage in 5 of the 8 Tc-W-inoculated dogs was indicated by development of ventricular-based arrhythmias, mainly ventricular premature contractions, between postinoculation days 60 and 170. In some dogs, ventricular premature contractions were multifocal. Electrocardiographic abnormalities progressively degenerated to various forms of ventricular tachycardia. Worsening ECG coincided with loss of left ventricular function as measured by echocardiography. Mean percent ejection fraction and percentage of fractional shortening decreased to 63% and 52% of control values, respectively. The left ventricular free wall (LVFW) thickness decreased and % septal: % LVFW thickening ratio increased, indicating a relative preservation of septal wall motion and LVFW hypokinesis. 89 NAL Call.

Language: English Descriptors: Ginkgo biloba; Leaves; Plant extracts; Antagonists; Medicinal properties; Pharmacology; Chemistry Abstract: Ginkgolides are unique twenty-carbon terpenes, occurring naturally only in the roots and leaves of Ginkgo biloba. The molecules incorporate a tert-butyl group and six 5-membered rings, and are specific and potent antagonists of platelet-activating factor (PAF), a potent inflammatory autacoid. Studies in animal models with the most potent ginkgolide, BN 52021, and other specific PAF antagonists have demonstrated that PAF plays an important role in pathologies such as asthma, shock, ischemia, anaphylaxis, graft rejection, renal disease, CNS disorders and numerous inflammatory conditions. Ginkgolides are now being developed as therapeutic agents and very promising results have been obtained in clinical trials on shock, organ preservation and thermal injury. In addition to ginkgolides, several other types of natural PAF antagonists have been identified from various medicinal plants. These compounds have not only helped to explain the pharmacological basis of several traditional medicines. but have also provided man with a valuable new class of therapeutic agents. 94 NAL Call.

Language: English Descriptors: Mice; Animal models; Melanoma Abstract: We developed and evaluated an in vivo athymic nude mouse model for tumor growth, angiogenesis, metastasis, and antineoplastic drug development. Melanoma cell lines expressing beta-galactosidase encoded by the Escherichia coli lac Z gene have been created by infecting an immortal murine melanocyte cell line with a recombinant retrovirus expressing the v-Ha-ras oncogene and lac Z to generate the MRB (melanoma, ras, beta-galactosidase) cell lines. The amelanotic, phorbol ester-independent, transformed melanoma cell lines developed tumors rapidly when injected subcutaneously into nude mice, as well as experimental lung metastases when injected i.v. into the tail vein. beta- galactosidase-expressing subcutaneous tumors and lung metastases stained blue with X-gal. The melanomas produced in nude mice have been characterized by using various histochemical and immunohistochemical staining methods to detect melanoma- and endothelial-cell-specific markers to determine the extent of neovascularization in MRB nude mouse tumors. Optimal staining of endothelial cells involved in tumor angiogenesis was observed by using ADPase activity and antiangiotensin-converting enzyme antibody staining. Attempts at indirect quantification of metastatic tumor cell number within the lung by either beta- galactosidase enzymatic activity or ELISA immunoreactivity were unsuccessful. However, the MRB cell lines should be useful in screening for and studying the mechanisms of action of antineoplastic, antimetastatic, and angiostatic drugs in vivo in athymic nude mice. 95 NAL Call.

Language: English Descriptors: Rats; Candidosis; Candida albicans; Tongue lesions; Tongue; Opportunistic infections; Germfree state; Inbred strains; Induced resistance; Animal models; Disease models Abstract: Inbred germ-free Fischer 344 albino rats were evaluated as models for experimental candidiasis in order to investigate bacterial interaction with Candida albicans. Female rats were exposed to C. albicans in their drinking water and killed at intervals from 2 to 22 days after initial contact with the contaminant. C. albicans was cultured from their mouths from day 2 but from day 12 the number of colonies decreased. From day 2 to 9 all rats showed oral histological signs of candidal infestation, but after 9 days the number declined to 3 out of 9 at 22 days. The dorsal surface of the tongue was the best histological indicator of candidal infestation. All the rats had tongue lesions from day 4 to 9, and from day 6 there was also a concomitant localized loss of filiform papillae. The number of rats with all forms of tongue involvement also decreased after 9 days with only 3 out of 9 affected at 22 days. It is concluded that Fischer 344 inbred germ-free rats can be used on a limited scale as a model for candidiasis and bacterial interaction with C. albicans, the dorsal surface of the tongue would be the best site for studying candidal experimental lesions and it is probable that better results can be achieved with complete standardization of contamination and preparation procedures. 96 NAL Call.

A bovine strain isolated from a case of mastitis produced gross and histological changes in most of the glands; one bovine and one avian faecal isolate did not. Histologically, lesions were characterised by neutrophil infiltration in the alveolar spaces and necrosis and oedema in the interalveolar tissue. On bacteriological examination, the bovine mastitis strain could be isolated from most of the glands, but neither of the faecal strains. The mouse, therefore, appears to provide a convenient model for studying campylobacter mastitis. 99 NAL Call.

Language: English Descriptors: Cattle; Mice; Disease models; Mycobacterium paratuberculosis; Enteritis; Experimental infection; Cachexia; Pathogenesis; Immunological deficiency; Histology Abstract: Severe combined immunodeficient beige mice were inoculated orally and intraperitoneally with a bovine strain of Mycobacterium paratuberculosis to explore their potential as laboratory animal models in the study of paratuberculosis (Johne's disease). Control animals were similarly inoculated with heat-killed M. paratuberculosis. In the mice inoculated intraperitoneally, focal lesions and acid-fast bacilli were first detected in the livers (4 weeks postinfection) and later in the spleens and intestines of the test but not the control animals. No bacteria were seen in the hearts, kidneys, or lungs. At 12 weeks postinfection, all test mice had significant losses in body weight compared with those in controls (P < 0.05), a characteristic sign of bovine paratuberculosis. Tumor necrosis factor alpha was not detected in the serum. Histologic lesions were seen in the intestines, livers, and spleens of the animals in the orally inoculated test group after 26 weeks of infection. Our results suggest that the severe combined immunodeficient beige mouse may be a useful model for the investigation of paratuberculosis and cachexia and the evaluation of antimycobacterial drugs. 100 NAL Call.

Language: English Descriptors: Pigs; Edema; Latent infections; Disease models; Escherichia coli; Enterotoxemia; Animal models; Oral administration Abstract: An experimental model for subclinical edema disease was developed in weanling pigs. In multiple experiments, 3-week-old pigs were weaned, then inoculated intragastrically with 10(10) colony-forming units of an SLT-IIv- positive strain of Escherichia coli originally isolated from a pig with edema disease (principals). Control pigs were inoculated with a nonpathogenic E coli strain. Of 39 principals, 8 developed clinical edema disease within 14 days after inoculation. However, 20 of 21 principals that did not develop clinical signs of edema disease, but were submitted for necropsy examination at 14 days after inoculation, had characteristic vascular lesions of edema disease. Vascular lesions, found principally in ileum and brain, consisted of segmental necrosis of myocytes in the tunica media of small arteries and arterioles. None of the pigs inoculated with a nonpathogenic strain of E coli developed edema disease or vascular lesions. None of the principals necropsied at 2 days after inoculation had vascular lesions. Development of vascular lesions by 14 days after inoculation was used as the end point for detecting subclinical edema disease in the model. 101 NAL Call.

Language: English Descriptors: Body weight; Liver; Kidneys; Erythrocytes; Cell membranes; Sodium; Potassium; Atp; Adenosinetriphosphatase; Enzyme activity; Hypothalamic lesions; Food intake; Body fat; Rats Abstract: To determine whether body composition and body size changes induced by specific hypothalamic nucleus destruction alter peripheral tissue Na,K- ATPase activity, measurements of red cell, liver and kidney membrane Na,K- ATPase were made in female rats previously subjected to ablation of the dorsomedial hypothalamic nucleus (DMN). Results were compared to those obtained from rats with ventromedial hypothalamic nucleus (VMN) ablation or sham operation. Predictable body size and composition changes occurred in the DMN- lesioned animals (reduced body weight, length and food intake, normal carcass fat) and VMN-lesioned rats (normal body weight and food intake, reduced body length, increased carcass fat). Tissue Na,K-ATPase activity was, however, unaffected by hypothalamic ablation in either preparation, as shown by comparison to sham-operated controls. It is concluded that animal models of acquired obesity (VMN-lesioned rat, diet-induced obesity) and body size manipulation (DMN-ablated rat) are not dependent upon changes in membrane Na,K- ATPase activity in various tissues. Although the VMN and DMN have been reported by other laboratories to contain factors that can influence Na,K-ATPase activity, destruction of these hypothalamic loci was not associated with systemic changes in the activity of this enzyme. 106 NAL Call.

Laboratory animal science v. 42 (1): p. 35-37; 1992 Feb. Includes references. Language: English Descriptors: Saimiri sciureus; Hyperbilirubinemia; Fasting; Animal models; Bilirubin Abstract: The plasma of Bolivian squirrel monkeys, unlike that of Brazilian squirrel monkeys, is markedly yellow due to unconjugated hyperbilirubinemia after an overnight fast. The fasting hyperbilirubinemia in Bolivian squirrel monkeys is likely due to two mechanisms. First, a twofold increase in the bilirubin turnover/production rate occurs during a 24-hour fast. A second mechanism is the decreased hepatic conjugation potential for bilirubin due to the presence of a higher bilirubin UDP-glucuronosyltransferase (UDPGA)Km and a lower Vm; this results in higher steady-state plasma and hepatic bilirubin levels during a fast when hepatic UDP-glucuronic acid levels are low. The Bolivian squirrel monkey provides an excellent animal model for human Gilbert's syndrome type I in which to study rate-limiting mechanisms in the movement of bilirubin from plasma to bile. 107 NAL Call.

Literature review. Includes references. Language: English Descriptors: Dietary fat; Fat consumption; Immune response; Fat deficiencies; Fatty acids; Lymphocytes; Monocytes; Macrophages; Neutrophils; Cholesterol; Nutrition physiology; Literature reviews Abstract: Changing the concentration or the type of fat intake impacts several aspects of the immune response involving lymphocytes, monocytes, and neutrophils. An increase in the intake of fat inhibited immune response in humans and in several animal models. Polyunsaturated fatty acids (PUFA) of N-6 type lowered immune response in several animal models, but a moderate increase in the consumption of N-6 PUFA by humans did not have any detectable adverse effect on the immune response. In humans, several indices of immune response were inhibited by the N-3 PUFA, but in animals both inhibition and stimulation were found, depending upon the species, the fatty acids used and the index being examined. Whether the absolute amounts or the ratios between individual fatty acids or fatty acid classes are critical in determining their effects on immune response need to be investigated. Manipulation of fat intake has already found limited success in managing some of the disorders of the immune system and further use of this treatment is anticipated. 108 NAL Call.

Language: English Descriptors: Anorexia nervosa; Food restriction; Feeding behavior; Activity; Stress; Food intake; Body weight; Estrous cycle; Mortality; Gastric ulcer; Histopathology; Animal models; Female animals; Rats Abstract: The present study investigated the application of female rats with activity stress as an animal model for anorexia nervosa. Young female rats were singly housed in activity-wheel cages with food-restricted schedule (2, 3, or 4 h of food availability per day) for 3 weeks. Estrous cycle, body, weight, food intake, and wheel revolution were recorded daily. Gastric pathology was also observed using the endoscopic technique. Rats that were subjected to either a 3- or 4-h feeding schedule exhibited the cessation of estrous cycle, loss of body weight, and suppression of food intake. These animals also showed a remarkable increase in running activity. However, they had no gastric lesions throughout the experimental period. On the contrary, the 2-h feeding schedule elicited severe gastric lesions and high mortality. The results suggest that behavioral and physiological changes of the young female rats with 3 or 4 h feeding share some symptoms of anorexia nervosa, although their anorexia is not self starvation. 109 NAL Call.

Language: English Descriptors: Listeria monocytogenes; Foodborne diseases; Inoculum; Inoculum density; Infection; Symptoms; Disease models; Macaca fascicularis Abstract: One of the major unanswered questions regarding the presence of Listeria monocytogenes in foods is how many cells must be ingested in order to cause illness. To answer this question, studies were undertaken by using Macaca fascicularis (cynomolgus monkey) as an animal model. Healthy nonhuman primates were dosed with various concentrations of L. monocytogenes suspended in sterile whole milk. Final concentrations of 10(5), 10(7), and 10(9) total cells of the organism were used; a control was also included. Blood samples, as well as fecal and nasal specimens, were taken at various time intervals. Only animals that received 10(9) cells of L. monocytogenes became noticeably ill, with symptoms of septicemia, irritability, loss of appetite, and occasional diarrhea. Monkeys that received 10(7) and 10(9) cells shed L. monocytogenes in the feces for approximately 21 days. In monkeys that received the dose of 10(9) cells, severe lymphopenia and neutrophilia occurred within 48 h. In a separate trial, monkeys received Maalox to reduce the gastric acidity of the stomach. However, no substantial differences were observed between Maalox-treated and control monkeys. 110 NAL Call. No.: QP141.A1J68 Food antigens in human milk. Jakobsson, I.

Includes references. Language: English Descriptors: Fulvic acids; Supplements; Selenium; Mineral deficiencies; Bone diseases; Collagen; Heat stability; Proline; Lysine; Bone strength Abstract: High concentrations of fulvic acid and selenium deficiency are the main causative factors of Kashin-Beck disease, an endemic, chronic and degenerative osteoarticular disorder found in China. In the search for an animal model of this disease, mice were exposed to these pathogenetic conditions for two generations and the collagen types from skin, bone and cartilage were analysed. The growth of the treated mice was slightly retarded, and the rate of reproduction was lower in animals maintained on a fulvic acid- supplemented and/or selenium-deficient diet. Irregular bone formation was seen by radiography and morphometry. Biochemical analysis indicated that lysine residues in collagen I from bone and in collagen II from cartilage were overmodified. The values of Hyl/(Hyl + Lys) in bone collagen alpha 1(I) chains from treated mice were about 0.434-0.484, i.e. substantially higher than that of the control (0.277). The values of this parameter for collagen II were 0.482 for control and 0.546-0.566 for treated mice. The melting temperature of collagen I from bones of treated mice was 1 degrees C lower than that of control collagen, indicating decreased thermal stability. The breakage point of the tibiae of treated mice occurred at a lower preload force than for controls, suggesting that the overmodified and thermally less stable collagen molecules are causally related to a lower mechanical strength of bones. 112 NAL Call.

Language: English Descriptors: Human diseases; Disease models; Rats; Triacylglycerol lipase; Lysosomes; Symptoms; Pathology Abstract: We describe a new animal model of a genetic lipid storage disease analogous to human Wolman's disease. Affected Donryu rats, who inherited the disease in an autosomal recessive mode, manifested marked hepatosplenomegaly, lymph node enlargement, and thickened, dilated intestine. Morphologically, many characteristic foam cells were observed in livers and spleens. No adrenal calcification could be found in affected rats. Biochemical studies on spleen and liver tissues showed massive accumulation of esterified cholesterol and triglycerides, and deficiency of acid lipase for [14Cl-cholesteryl oleate. This animal model could contribute greatly to the clarification of the physiological and pathological roles of lysosomal acid lipase in the metabolism of lipoproteins and cholesterol, and of the pathogenesis of atherosclerosis. 115 NAL Call.
