Microcystin toxicity in a freshwater fish, Heteropneustes fossilis (Bloch)
Microcystin is a toxin secreted by cyanobacteria, which are the dominant phytoplankton in eutrophic freshwater bodies. The present study reports histopathological, hematological and biochemical changes in the freshwater fish, Heteropneustes fossilis due to toxicity of microcystin. Toxic effects were observed in liver, kidney, corpuscles of Stannius, gills and gonads. Bilirubin concentration inc...
متن کاملEffect of Cd++ On Catalase Activity on Air Breathing Fresh Water Teleost Fish Heteropneustes fossilis (Bloch)
The objective of this study is to determine the effect of Cadmium (a heavy metal) on Catalase activity on tissues of liver, kidney and gill of freshwater air breathing Teleost fish (Heteropneustes fossilis). Catalase, a oxido-reductase enzyme play an important role in anti-oxidant defence System which protect animal from oxidative stress. Heteropneustes fossilis (Bloch), a medicinally important...
متن کاملDose- and time-dependent micronucleus induction in peripheral erythrocytes of catfish, Heteropneustes fossilis (Bloch) by zinc
As far as the detection of metal genotoxicity in fish is concerned, micronucleus (MN) test is considered an extremely suitable measure. In this study, frequencies of micronucleated erythrocytes were scored in peripheral blood of catfish, Heteropneustes fossilis (bloch) after acute in-vivo exposure of zinc at different concentrations (5, 10 and 30 ppm) in the laboratory condition. These three co...
متن کاملTestosterone and estradiol-17 beta dependent phospholipid biosynthesis in ovariectomized catfish, Heteropneustes fossilis (Bloch).
Effect of cumulative doses (7, 14 and 28 mg kg(-1) body weight) of testosterone (T) and estradiol-17 beta (E2) on total phospholipids (TP), phosphatidylcholine (PC), phosphatidylserine (PS), phosphatidylinositol (PI) and phosphatidylethanolamine (PE) in tissues were investigated during the gonadal recrudescence, in prespawning phase of the annual reproductive cycle in intact and ovariectomized ...
متن کاملEffect of Bisphenol A on certain Hematological Parameters of Heteropneustes fossilis, Bloch
Effect of Bisphenol A on the hematological parameters total RBC count, total WBC count and hemoglobin content was assessed in Heteropneustes fossilis caught from wild. Behavioural changes were also monitored. It was found that 72 hour exposure of BPA at a concentration of 0.1g/L has lowered total RBC count and increased WBC count. Hemoglobin concentration in the blood also decreased exposure to...
