2、白表達(dá)及梗死面積的影響。結(jié)果:冠心合劑治療組及陽性對照組血清VEGF濃度及心肌VEGF蛋白的表達(dá)增加,高于模型組和假手術(shù)組(P<0.05);隨冠心合劑劑量的增加,梗死面積逐漸減小;冠心合劑大劑量組療效與西藥對照組無明顯差異(P>0.05)。結(jié)論:冠心合劑可能通過促進(jìn)心肌梗死大鼠心肌VEGF蛋白表達(dá)、分泌,從而促進(jìn)梗死心肌血管新生。關(guān)鍵詞:冠心合劑;心肌梗死;血管內(nèi)皮生長因子;促血管新生中圖分類號:R285.5文獻(xiàn)標(biāo)識碼:A文章編號:1673-7717(2011)02-0247-03EffectsofGuanxinDecoctionontheExpr
