Sympathetic effects on the steroidogenesis and proliferation of adrenocortical cells in vitro.

abstract：INTRODUCTION:Adenosine deaminase (ADA), purine nucleoside phosphorylase (PNPase), S-adenosylhomocysteine hydrolase (SAHH), 5'-nucleotidase (5N), and deoxycytidine kinase (dCK) are involved in purine salvage metabolism. Changes of the activities of the above enzymes have been observed in blood cells in patients with imm...
