Effect of age and sex on the ascorbic acid content of kidney, skeletal muscle and pancreas of common Indian toad, Bufo melanostictus.

Ascorbic acid decreases from age-group I to II in Kidney, skeletal muscle, and increases in the Pancreas of female. There is no significant change in the Pancreas of male toad. There is an increase in the ascorbic acid content from age group II to III except in the Pancreas of females, where there is a decline of the content. Ascorbic acid remains constant in age-group IV except in the kidney of female, skeletal muscle of both sexes showing an increase and decrease of the value respectively. Sex difference shows a higher content in kidney of group IV, in skeletal muscle of group II and III and in pancreas of group II and is less in kidney of age-group II of females over their male counterparts.
