Abstract

Carbohydrate depletion (glucose and glycogen) was reported to be a major problem in acute arsenic poisoning (Berry and Smythe 1959; Reichl et al., 1988; Szinicz and Forth 1988). Present study was undertaken to evaluate the effect of sodium arsenite on glucose and glycogen levels in various tissues subjected to sub lethal concentration for the period of 24, 48, 72 and 96 hours. A significant depletion in glucose and glycogen levels (P < 0.005) in various tissues of Tilapia mossarnibica was observed in the present study. The change in glycogen and glucose contents was found to be tissue specific and time dependent. The present data revealed that sodium arsenite has a role in the depletion of carbohydrates, a major fuel of the organism.
