[Effect of splenin and its fractions on the functional state of the adrenal cortex]

Effect of splenin (1 ml) and its fractions (0.5 ml) on adrenocortical function was studied after a single intramuscular injection of the preparations into rats. Splenin and its fractions containing water-soluble substances reduced the content of ascorbic acid in the rat adrenals thereby indicating the increased synthesis of adrenocortical hormones. Adenosine-5-monophosphate is one of the basic biological substances contained by splenin and its water-soluble fractions. It produces a stimulant effect on the synthesis of adrenocortical hormones.
