Abstract:
Objective To explore the proper proportion of effective fractions in Shengmaisan(saponins of Radix ginseng,saponins of Radix ophiopogonis,Lignans of Fructus schisandrae)in different anoxia models.Methods Acute cerebral hypoxia was induced by sodium nitrite and decapitation in mice,and the orthogonal design was used in these two models to find the proper proportion of three effective fractions.The gasping time of the mice,which were decapitated was observed to compare the anti-anoxia effects of XZF with other clinical drugs,and cerebral ischemic reperfusion injury model of mice was also used to study the effect of XZF on related biochemical index.Results XZF(the proportion of saponins of Radix ginseng,saponins of Radix ophiopogonis,Lignans of Fructus schisandrae as 7 ∶ 2 ∶ 6)significantly prolonged the gasping time,and decreased brain nitrogen monoxidum(NO)content after reperfusion of the mice at dosages of 50 mg/kg and 150mg/kg.Meanwhile,XZF also reduced malondialdehyde(MDA)content and increased superoxide dismutase(SOD)activity at the higher dosage.Conclusion XZF obtained by experimental screening exerts a significant protective effect on cerebral ischemia injury in mice,which provide some pharmacological evidence for further development of new modern Chinese drug composed with effective fractions for cerebral vascular diseases.
