Objective: To observe the effect of Gingko compound recipe granula on brain tissue SOD vigor and morphology in rats models of vascular dementia. Methods : Established Vascular Dementia rats models in common carotid artery repeatedly occlusion and Sodium Nitroprusside intraperitoneal injection, measured SOD vigor in brain tissue, and observed hippocampus cell morphology variation. Results : Compared with Model group, SOD vigor of Gingko compound recipe granula group enhanced obviously, the difference is statistically significant,and nerve cel...
