title: [Effect of nizofenone on the symptomatic vasospasm after aneurysmal subarachnoid hemorrhage and its relationship to the levels of serum complements (CH50, C3 and C4)].
abstract: Serum complements (CH50, C3 and C4) after aneurysmal subarachnoid hemorrhage were measured in 42 patients over 2 to 3-week period. Nizofenone, an anti-vasospasmotic agent, was administered to 11 patients. In the nizofenone-treated group, 8 patients showed decreased serum C4 levels 5 days after the onset of subarachnoid hemorrhage, but among them, only 2 patients showed symptomatic vasospasm. Considering our previous data (majority of patients who showed decreased serum C4 levels presented with symptomatic vasospasm), these results suggest a favorable effect of nizofenone on the symptomatic vasospasm after aneurysmal subarachnoid hemorrhage.
