Sympathetic functions in NG-nitro-L-arginine-methylester-induced hypertension

Abstract

The nitric oxide synthase blockade-induced hypertension seems to be associated with increased adrenal-medullary system and renin-angiotensin system activities. The increased Gs-adenylyl cyclase activity after chronic inhibition of formation of nitric oxide suggests that nitric oxide plays a modulatory role in formation of cyclic AMP, to which angiotensin II seems to contribute through an angiotensin II type 1 receptor-mediated mechanism.
