The function of nitric oxide in spastic cerebral arteries after subarachnoid hemorrhage (SAH) was angiographically investigated in dogs. On days 4 and 7, after two intracisternal injections of autologous blood, higher concentrations of L-arginine than those of endogenous L-arginine in the cerebrospinal fluid produced a transient vasodilation of the spastic… (More)
