Mercuric chloride induced alterations in the intestinal transport of glucose in the fresh water murrel,Channa Punctatus

Abstract

The effect of five concentrations of mercuric chloride on the uptake of glucose from the intestine of the fresh water murrel, Channa punctatus was studied. Intestinal glucose transport was also assessed in fish exposed to a sublethal concentration of mercuric chloride for 10 and 30 days. The results show that the uptake of glucose from the intestine was reduced by all five concentrations of mercuric chloride. In fish exposed to mercuric chloride in laboratory media, the reduction of glucose absorption was greater after 30 days of exposure than after 10 days.
