Microcystin-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 کاملAlterations in the Corpuscles of Stannius of Euphorbia royleana Treated Catfish, Heteropneustes fossilis
Background: We aimed to evaluate effect of Euphorbia royleana exposure on histocytology of corpuscles of Stannius in fish, Heteropneustes fossilis. Methods: Fish were subjected to 2.47 mg/L and 0.618 mg/L of E. royleana for short-term and long-term exposure, respectively. Blood samples were collected on 24, 48, 72 and 96 h in short-term and after 7, 14, 21, and 28 d in long-term experiment a...
متن کاملPinealectomy , ovarian activity and vitellogenin levels in the catfish , Heteropneustes fossilis ( Bloch ) , exposed to various combinations of photoperiods
To assess the role of the pineal gland in the regulation of ovarian activity, female catfish were exposed to various combinations of photoperiods during the postspawning period of the annual reproductive cycle. Ovarian recrudescence and vitellogenin synthesis were accelerated after pinealectomy in catfish maintained under short photoperiod (9L : 15D) at 25 °C. However, at 25 °C, under long (14L...
متن کاملEnvironmental Hypertonicity Causes Induction of Gluconeogenesis in the Air-Breathing Singhi Catfish, Heteropneustes fossilis
The air-breathing singhi catfish (Heteropneustes fossilis) is frequently being challenged by different environmental insults such as hyper-ammonia, dehydration and osmotic stresses in their natural habitats throughout the year. The present study investigated the effect of hyperosmotic stress, due to exposure to hypertonic environment (300 mM mannitol) for 14 days, on gluconeogenesis in this cat...
متن کاملMicrocystin-lr Attenuates Blood Calcium and Phosphate Levels in Stinging Catfish Heteropneustes Fossilis
The present study was aimed to investigate the effects of microcystin–LR (MCLR) on the blood electrolytes of Heteropneustes fossilis. The fish were injected microcystinLR (2.5 μg/25 g) intraperitoneally at the initiation of the experiment. Blood samples were collected and the serum calcium and phosphate levels were estimated at 1, 3, 5, 10, 15 days. There is no change in serum calcium level of ...
