Ahmad, M., M. Ahmad, R. Hasan, and A. Qureshi (2005). The effects of isoniazid (INH) on the hematocrit of the lizard, Uromastix hardwickii. Pakistan Journal of Pharmaceutical Sciences 18(1): 52-54. ISSN: 1011-601X.
Abstract: In recent years isoniazid has been used as an antituberculous chemophylactic agent. Severe adverse reactions have been reported following its extensive treatment. In addition to hepatic and neurologic disturbances, hematologic alterations have also been reported. Present study was conducted to determine the effect of 0.06 mg isoniazid on the lacertilian packed cell volume. It was 14.0 per cent on day 5, 18.0 and 19.8 per cent on day 10 and day 15 respectively, whereas, it was 24.0, 24.2 and 24.6 per cent in controls on day 5, 10 and day 15 respectively.

Abstract: This study deals with the effect of 7.1 mg/day, 10.5 mg/day and 14 mg/day doses of mefenamic acid administered for 12 days to three groups of Uromastix hardwickii respectively. Individual blood samples were obtained from the anterior abdominal vein and hemoglobin content was determined. The hemoglobin in test was 5.1 g/100 ml compared to 8.0 g/100 ml of controls in experiment I and its amount remained almost similar in the case of experiment II, whereas, 4.5 g/100 ml was observed of test compared to 8.0 g/100 ml of their counterparts.

NAL Call Number: QH573.T5
Abstract: The fine structure and differential cell count of blood and coelomic exudate leukocytes were studied with the aim to identify granulocytes from Ameiva ameiva, a lizard distributed in the tropical regions of the Americas. Blood leukocytes were separated with a Percoll cushion and coelomic exudate cells were obtained 24 h after intracoelomic thioglycollate injection. In the blood, erythrocytes, monocytes, thrombocytes, lymphocytes, plasma cells and four types of granulocytes were identified based on their morphology and cytochemistry. Types I and III granulocytes had round intracytoplasmic granules with the same basic morphology; however, type III granulocyte had a bilobued nucleus and higher amounts of heterochromatin suggesting an advance stage of maturation. Type II granulocytes had fusiformic granules and more mitochondria. Type IV granulocytes were classified as the basophil mammalian counterpart based on their morphology and relative number. Macrophages and granulocytes type III were found in the normal coelomic cavity. However, after the thioglycollate injection the number of type III granulocyte increased. Granulocytes found in the coelomic cavity were related to type III blood granulocyte based on the morphology and cytochemical localization of alkaline phosphatase and basic proteins in their intracytoplasmic granules. Differential blood leukocyte counts showed a predominance of type III granulocyte followed by lymphocyte, type I granulocyte, type II granulocyte, monocyte and type IV granulocyte. Taken together, these results indicate that types I and III granulocytes correspond to the mammalian neutrophils/heterophils and type II to the eosinophil granulocytes.

NAL Call Number: 444.8 G28
Abstract: The natriuretic peptide (NP) system is a complex family of peptides and receptors that is primarily linked to the maintenance of osmotic and cardiovascular homeostasis. In amphibians, the potential role(s) of NPs is complicated by the range of osmoregulatory strategies found in amphibians, and the different tissues that participate in osmoregulation. Atrial NP, brain NP, and C-type NP have been isolated or cloned from a number of species, which has enabled physiological studies to be performed with homologous peptides. In addition, three types of NP receptors have been cloned and partially characterised. Natriuretic peptides are always potent vasodilators in amphibian blood vessels, and ANP has been shown to increase the permeability of the microcirculation. In the perfused kidney, ANP causes vasodilation, diuresis and natriuresis that are caused by an increased GFR rather than effects in the renal tubules. These data are supported by the presence of ANP receptors only on the glomeruli and renal blood vessels. In the bladder and skin, the function of NPs is enigmatic because physiological analysis of the effects of ANP on bladder and skin function has yielded conflicting data with no clear role for NPs being revealed. Overall, NPs often have no direct effect, but in some studies they have been shown to inhibit the function of AVT. In addition, there is evidence that ANP can inhibit salt retention in amphibians since it can inhibit the ability of adrenocorticotrophic hormone or angiotensin II to stimulate corticosteroid secretion. It is proposed that an important role for cardiac NPs could be in the control of hypervolaemia during periods of rapid rehydration, which occurs in terrestrial amphibians.

Gaitanaki, C., M. Papatriantafyllou, K. Stathopoulou, and I. Beis (2006). Effects of various oxidants and antioxidants on the p38-MAPK signalling pathway in the perfused amphibian heart. Molecular and Cellular Biochemistry 291(1): 107-117. ISSN: 0300-8177.
Abstract: We investigated the effects of different antioxidants such as L-ascorbic acid, catalase, and superoxide dismutase (SOD), on the p38-MAPK activation induced by oxidative stress in the isolated perfused amphibian heart. Oxidative stress was exemplified by perfusing hearts with 30 (So(BM H subscript 2(BO subscript 2(B for 5 min or with the enzymatic system of xanthine/xanthine oxidase (200 (So(BM/10 mU/ml, respectively) for 10 min. H subscript 2(BO subscript 2(B-induced activation of p38-MAPK (7.04 +/- 0.20-fold relative to control values) was totally attenuated by L-ascorbic acid (100 (So(BM) or catalase (150 U/ml). These results were confirmed by immunohistochemical studies in which the phosphorylated form of p38-MAPK was localised in the perinuclear region and dispersedly in the cytoplasm of the ventricular cells during H subscript 2(BO subscript 2(B treatment, a pattern that was abolished by catalase or L-ascorbic acid. p38-MAPK was also activated (2.34+/- 0.17-fold) by perfusing amphibian hearts with the reactive oxygen species (ROS)-generating system of xanthine/xanthine oxidase and this activation sustained in the presence of 150 U/ml catalase (2.16 +/- 0.26-fold), 50 U/ml SOD (2.02 +/-0.07) or 100 (So(BM L-ascorbic acid (2.18 +/- 0.10), but was suppressed by the combination of 150 U/ml catalase and 50 U/ml SOD. Finally, our studies showed that xanthine/xanthine oxidase induced the phosphorylation of the potent p38-MAPK substrates MAPKAPK2 (3.14 +/- 0.27-fold) and HSP27 (5.32 +/- 0.83-fold), which are implicated in cell protection, and this activation was reduced by the simultaneous use of catalase and SOD.
