Inducible nitric oxide synthase pathway in the central nervous system and vasopressin release during experimental septic shock.
Septic shock is characterized by arteriolar vasodilation and hypotension. We have tested the hypothesis that nitric oxide arising from inducible nitric oxide synthase in the central nervous system is responsible for the deficiency in vasopressin release and consequent hypotension during experimental septic shock. ⋯ These data indicate that central nitric oxide arising from the inducible nitric oxide synthase pathway plays an important inhibitory role in vasopressin release during experimental septic shock and may be responsible for the hypotension occurring in this vasodilatory shock.
