Abstract
Objective To investigate the effects of panax notoginseng saponins on neurological function of rats with ischemia reperfusion and on expression of hippocampus ′s glucose transporter 1 ( GLUT-1).Methods Sixty-eight healthy adult male wistar rats were randomly divided into sham-operate group (A),saline control group(B)and PNS therapy group of small-dose group(C1 =50 mg/kg),dose group(C2 =100 mg/kg),high-dose group(C3 =150 mg/kg),the C1,C2,C3 and B group were redivised into ischemia-reperfusion 0 h,2 h,4 h and 6 h subgroups according to the intervention time points ( n=4 in each group ) . By using the suture method to complete the rat middle cerebral artery occlusion model preparation .The neurological deficit in rats was evaluated by using behavioral score .The corresponding doses of PNS or an equal volume of saline were injected intraperitoneally administered at ischemia for 2 h and reperfusion for 0 h,2 h,4 h and 6 h in the PNS groups and the saline control group .Immunohistochemistry assay was used to detect the expressions of GLUT-1 in the hippocampus of ischemic sides at ischemia-reperfusion. Results Behavioral score:the neurological score of group A was 0.The nerve function of group C defect were significantly less than the B group ( P<0.01 ) .The group C 3 was the least among the three groups C 1 , C2 and C3 .The results of immunohistochemistry assay ,the number of GLUT-1 positive cells of group A was significantly less than group B and C ( all P<0.01 ) .The number of GLUT-1 positive cells in brain tissue of rats in the same intervention time point of the group C were significantly more than group B ( all P<0.01 ) , and group C3 was the most.Among different therapy time groups ,the expression of GLUT-1 were basically the same(P>0.05).Conclusion PNS can lessen the degree of neurologic impairment in ischemia-reperfusion rats by promoting the expression of GLUT-1,and maintain the brain energy .关键词
