ABSTRACT
Objective To observe the effects of icarisid Ⅱ (ICS Ⅱ)on cognitive deficits and expression of synaptophysin(SYN)in chronic cerebral hypoperfusion(CCH)rat models.Methods 40 male SD rats were randomly divided into four groupsnormal group,sham operation group,model group and ICSⅡgroup.The model was established by permanent bilateral common carotid artery occlusion(BCCAO).ICS Ⅱ group was administered ICS Ⅱ at a dose of 8mg·kg -1 ·d -1 by gavage on 1st day after modeling.Sham group and CCH group were injected double -distilled water.The escape latency(s)and spatial probe times were measured by water maze test.Then,the morphology change and expression of SYN in hippocampal were assayed by HE and immunohistochemistry analysis.Results At the 1st month and 2nd month,the escape latency in the model group[(40.02 ±4.95)s,(42.29 ±5.75)s]were significantly prolonged compared with the sham operation group[(26.43 ±2.68)s,(26.84 ±2.06)s](t =4.89,5.06,all P 0.05 ). Conclusion ICS Ⅱ can improve the cognitive deficits in CCH rat models and this effect may be associated with increased expressions of SYN in hippocampal.
