Alternations in the activity of some digestive enzymes of Channa punctatus, exposed to lead nitrate

K V Sastry et al. Bull Environ Contam Toxicol. 1978 May.

Abstract

The effect of exposure of Channa punctatus to a sub-lethal concentration of lead nitrate on the activities of alkaline phosphatase, acid phosphatase amylase, maltase, lactase, trypsin and pepsin has been investigated. A decrease in the activity of alkaline phosphatase has been recorded after 15 days of exposure but there was no significant change after 30 days. Acid phosphatase showed an elevation in activity of both stages. All the three carbohydrases shows elevation after 15 days, followed by an inhibition after 30 days of treatment. The activity of pepsin and trypsin remained above the normal level throughout the tensure of the experiment reveal that the pattern of alteration in enzyme activities is different in liver and digestive system.
