Gas exchange with air and water in an air-breathing catfish, Saccobranchus (Heteropneustes) fossilis.
Recent studies on air-breathing fish have shown that different species are adapted in varying degrees for gaseous exchange in both water and air. In the lungfishes these differences are correlated with different degrees of development of the gills, the efficiency of the lung in gas exchange, and the respiratory properties of the blood (Lenfant, Johansen & Grigg, 1966; Johansen & Lenfant, 1967, ...
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 کاملToxic impact of lethal concentration of lead nitrate on the gills of air-breathing catfish Heteropneustes fossilis (Bloch)
Toxicopathological impact of lethal concentration (925 mg/l) of lead nitrate on the gills of air-breathing catfish Heteropneustes fossilis was analysed. Following exposure the gills exhibited rapid alterations that include detachment and lifting of the epithelial linings from the surfaces of the gill filament (primary, PL) and respiratory (secondary, SL) lamellae. This led to extensive haemorrh...
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 کاملUnusual hepatic mitochondrial arginase in an Indian air-breathing teleost, Heteropneustes fossilis: purification and characterization.
A functional urea cycle with both cytosolic (ARG I) and mitochondrial (ARG II) arginase activity is present in the liver of an ureogenic air-breathing teleost, Heteropneustes fossilis. Antibodies against mammalian ARG II showed no cross-reactivity with the H. fossilis ARG II. ARG II was purified to homogeneity from H. fossilis liver. Purified ARG II showed a native molecular mass of 96 kDa. SDS...
