| 摘 要： | 目的观察中药胃康宁含药血清对胃癌细胞生长和VEGF及其受体表达的作用。方法分别以高、中、低等不同剂量的胃康宁制剂对Wistar雄性大鼠进行灌胃,制备含药血清,然后分别用不同剂量组合药血清培养胃癌细胞,以倒置显微镜及流式细胞仪观测各组胃癌细胞的生长状况,免疫组织化学SABC法检测各组胃癌细胞中血管内皮生长因子(vascular endothelial growth factor,VEGF)及其受体Flt-1的表达,RT- PCR法检测各组胃癌细胞中VEGF及其受体KDR,Flt-1 mRNA的表达。结果与对照组比较,用药组胃癌细胞的生长及细胞周期明显改变(P＜0．01),用药组G_0-G_1期细胞增多,S期细胞减少,凋亡率增加,并呈一定的量效关系。VEGF的灰度值由对照组的147．82±0．15升高到低剂量组的174．80±0．81,中剂量组的178．65±0．56,高剂量组的182．44±0．54(P＜0．01)。Flt-1的灰度值由对照组144．31±0．71升高到低剂量组148．20±0．69,中剂量组162．01±0．52,高剂量组168．51±0．81(P＜0．01)。胃康宁含药血清培养的胃癌细胞中V...
