Biochemical alterations induced by cadmium in the liver of Channa punctatus
Journal Article
·
· Environ. Res.; (United States)
Exposure of a freshwater fish, Channa punctatus, in a medium containing cadmium resulted in a decrease in the quantity of glycogen, protein, and RNA in the liver during the early period of exposure. On the other hand the cholesterol level showed a rise except for a slight decline for some time after the second week of exposure. However, an increase in glycogen, protein, and RNA content and a simultaneous decrease in cholesterol level was recorded thereafter for some time with lower concentrations only (i.e., <0.05 ppm Cd). Cadmium also brought about an enhancement in the activity of acid phosphatase and an inhibition in the activity of cholinesterase in the liver. With the exception of cholinesterase activity, fishes showed a general tendency toward temporary recovery when exposed to lower dosages of cadmium.
