Experiment and clinical study of up-regulation effect of captopril on the platelet nitric oxide synthase activity in patients with ischemic stroke / 临床神经病学杂志

Objective To investigate the up regulation of captopril on the platelet nitric oxide(NO) synthase and clinical application in patients with ischemic stroke.Methods The washed platelets in vitro of the patients with acute ischemic stroke and healthy controls were added with oxidized LDL(oxLDL) and captopril followed by measurement of platelet NO synthase activity.Plasma oxLDL,NO sythase,NO and platelet NO sythase,NO in 40 patients were measured before oral captopril and after oral captropril 1 month,3 months.Results (1)After the washed platelets in vitro were added with oxLDL,the platelet NO synthase activities of the patients and controls were all significantly decreased( P
