Abstract:

Serum electrolyte blood glucose, blood urea and serum cholesterol are estimated in four phases of annual biological cycle of Rana tigrina and Bufo melanostictus. Electrolytes level was high during aestivation and hibernation but level of Serum cholesterol, blood glucose and blood urea was low, During breeding and post breeding season electrolytes level was low but that of serum cholesterol, blood urea and blood glucose was high.

Keywords:

Serum electrolyte blood urea; blood glucose; serum cholesterol; Rana tigrina; Bufo melanostlctus
