Protective Effect of Alpha Tocopherol on Phenol Induced Oxidative Damage in Liver of Freshwater Catfish Heteropneustes Fossilis

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...

Histological Studies on Kidney of Cadmium Chloride Exposed Freshwater Catfish , Heteropneustes Fossilis ( Bloch )

Effects of lead nitrate on histo-cytological alterations of corpuscles of Stannius of stinging catfish, Heteropneustes fossilis

Background: The present study investigated the effects of lead nitrate on the histo-cytological changes in the corpuscles of Stannius (CS) of Heteropneustes fossilis. Methods: Catfish, Heteropneustes fossilis were subjected to 657.6 mg/L and 164.4 mg/L of lead nitrate for 96 h and 28 days, respectively. Blood from fish was collected on 24, 48, 72 and 96 h in short-term and after 7, 14, 21, an...

Cyto-architectural Alterations in the Corpuscles of Stannius of Stinging Catfish Heteropneustes fossilis after Exposure to a Botanical Pesticide (Nerium indicum)

Background: This investigation describes the cyto-architectural alterations observed in the corpuscles of Stannius of stinging catfish Heteropneustes fossilis after treatment with a botanical pesticide Nerium indicum. Methods: Heteropneustes fossilis were subjected to 11.27 and 2.81 mg/L of Nerium indicum leaf extract over short- and long-term exposure periods, respectively. Blood was collecte...

Biochemical Changes in Blood of Freshwater Catfish Heteropneustes fossilis Exposed to Microcystin-LR

Present study reveals the effects of microcystin-LR (2.5 μg/25g bw) toxins on certain biochemical parameters in blood of H. fossilis. In treated fish serum bilirubin, serum cholesterol, serum creatinine and serum urea levels are increased. Serum protein content of treated fish is decreased. Present study suggests that MCLR is toxic to fresh water catfish Heteropneustes fossilis.
