Excessive production of nitric oxide (NO) as result of inducible nitric oxide synthase (iNOS) induction has been implicated in the pathophysiology of hemorrhagic shock. Our aim was to study the effect of iNOS inhibitors, L-canavanine (50mg/kg) and N(G)-nitro- L-arginine methyl (L-NAME, 10mg/kg) and
OBJECTIVE
The portal hypotensive effect of vasopressin during hemorrhage is less effective than that during stable condition in cirrhotic patients or experimental portal hypertension (the so-called hyposensitivity phenomenon). Recent studies have demonstrated that constitutive nitric oxide
Hyposensitivity to vasopressin is a well documented phenomenon in animals with portal hypertension and patients with cirrhosis subject to haemorrhage. Haemorrhage is associated with the endogenous release of bradykinin, which may subsequently stimulate the formation of nitric oxide (NO). The present
