Abstract

Abstract

Objective To study antioxidant role and mechanism of Rg1 in rats with cerebral ischemia reperfusion injury (IRI) .Me thods One hundred and twenty healthy male rats were randomly divided into six groups: control group, sham operation group, model group, different concentration (30, 60, 90 mg/kg) of Rg1 treatment group.MCAO SD rats model was established by suture-occluded method;the Rg1 treatment groups were given Rg1 i.p. in advance, after 24 hours of reperfusion, neurobehavioral scores of all groups were examined by Longa's standard;The expression of Nrf2 and HO-1 were analyzed by western blot;The content of SOD and MDA was detected by kit.Re s ults The score of model group rats are significantly higher than control group, compared with the model group, the score of different concentration of Rg1 treatment group was decreased (P<0.05) . The Nrf2 and HO-1 expression in model group was mildly higher than the control or sham group (P <0.05) . Both of them in every Rg1 treatment group was higher than model group. Compared with control or sham group, SOD content was observably depressed but MDA content was dramatically increased in model group, interestingly, SOD contentwas enhanced, MDA content was attenuated in different concentration of Rg1 treatment group (P <0.05) .Conclusion Rg1 increases Nrf2 and HO-1 protein expression and SOD content, reduces MDA content, improves neurofunctional performance of rats after MCAO, and alleviates cerebral cerebral IRI.
