Effect of L-Ascorbic Acid on the Glycogen Contents during Mercury Intoxication in the Freshwater Bivalve, Parreysia cylindrica
Freshwater bivalve, Parreysia cylindrica was exposed to acute (0.6 ppm) and chronic (0.12 ppm) doses of HgCl2 and HgCl2 with several concentrations of ascorbic acid. Glycogen contents from mantle, foot, gills, gonads and digestive glands were estimated after 24 hours and 96 hours of acute and 7 days and 21 days of chronic exposure from each group of test animals. Depletion of glycogen contents in different tissues caused due to mercury stress was much more as compared to those exposed to HgCl2 with ascorbic acid.
