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 کاملMicrocystin-LR: Effects on Freshwater Catfish Heteropneustes fossilis Prolactin Cells
Background: Previous studies have been reported on the toxicity of Microcystin-LR, which is produced by cyanobacterial growth in fish, such as Heteropneustes fossilis (H. fossilis). However, no studies have been conducted on the effects of Microcystin-LR on the prolactin cells of H. fossilis. Methods: H. fossilis fish were intraperitoneally injected with Microcystin-LR (2.5μg/25g) and sacrif...
متن کاملVitamin D3-induced calcemic and phosphatemic responses in the freshwater mud eel Amphipnous cuchia maintained in different calcium environments.
Vitamin D3 (100 ng 100 g body weight-1 day-1) was administered intraperitoneally (i.p.) to the freshwater mud eel Amphipnous cuchia kept in artificial freshwater, calcium-free freshwater, low-calcium freshwater (0.2 mmol/l CaCl2) or calcium-rich freshwater (13.4 mmol/l CaCl2) for 15 days. Analyses of serum calcium and phosphate levels were performed on days 1, 3, 5, 10 and 15 after the beginnin...
متن کاملEstradiol Affects Prolactin Producing Cells and Calcium levels in a Teleost, Heteropneustesfossilis, Kept in Different Calcium Concentrations
Background: This study investigated the effects of estradiol on plasma calcium and prolactin cells of Heteropneustes fossilis kept in calcium-deficient and normal freshwater. Methods: Fish were deprived of food and divided into groups A-D. Group A and B were kept in artificial freshwater with normal electrolytes. Group C and D were maintained in calcium-deficient freshwater. Vehicle was admin...
متن کاملUnique Hepatic Cytosolic Arginase Evolved Independently in Ureogenic Freshwater Air-Breathing Teleost, Heteropneustes fossilis
Hepatic cytosolic arginase (ARG I), an enzyme of the urea cycle operating in the liver of ureotelic animals, is reported to be present in an ammoniotelic freshwater air-breathing teleost, Heteropneustes fossilis which has ureogenic potential. Antibodies available against mammalian ARG I showed no cross reactivity with the H. fossilis ARG I. We purified unique ARG I from H. fossilis liver. Purif...
