康腦液對腦缺血再灌注大鼠VEGF、HGF、Es表達的影響摘要：

目的：探究康腦液對腦缺血再灌注大鼠VEGF、HGF、Es表達的影響。

方法：將60只大鼠隨機分為正常對照組、模型組和康復(fù)組，模型組和康復(fù)組進行腦缺血再灌注處理?？祻?fù)組腹腔注射康腦液，每天1次，連續(xù)5天。使用免疫組織化學(xué)方法檢測VEGF、HGF、Es的表達情況，并進行Westernblot分析。

結(jié)果：模型組VEGF、HGF、Es表達明顯下降，康復(fù)組VEGF、HGF、Es表達明顯上升，與模型組相比有明顯差別（P<0.05）。Westernblot分析結(jié)果與免疫組織化學(xué)方法結(jié)果一致。

結(jié)論：康腦液能顯著促進腦缺血再灌注大鼠VEGF、HGF、Es的表達，具有顯著的保護作用。

Abstract:

Objective:ToinvestigatetheeffectofKangnaoyeontheexpressionofVEGF,HGFandEsinratswithcerebralischemia/reperfusion.

Methods:Sixtyratswererandomlydividedintonormalcontrolgroup,modelgroupandrecoverygroup,andcerebralischemia/reperfusiontreatmentwasperformedinthemodelgroupandrecoverygroup.Kangnaoyewasinjectedintotheabdominalcavityoftherecoverygrouponceadayfor5consecutivedays.TheexpressionofVEGF,HGFandEsweredetectedbyimmunohistochemistrymethod,andWesternblotanalysiswasalsoperformed.

Results:TheexpressionofVEGF,HGFandEsinthemodelgroupwassignificantlydecreased,whiletheexpressionofVEGF,HGFandEsintherecoverygroupwassignificantlyincreased,whichwassignificantlydifferentfromthatinthemodelgroup(P<0.05).TheresultsofWesternblotanalysiswereconsistentwiththoseofimmunohistochemistry.

Conclusion:KangnaoyecansignificantlypromotetheexpressionofVEGF,HGFandEsinratswithcerebralischemia/reperfusion,andhasasignificantprotectiveeffect.
