用中药高三尖杉酯碱（Ｈｏｍｏｈａｒｒｉｎｇｔｏｎｉｎｅ）及血栓通（ＸｕｅＳｈｕａｎＴｏｎｇ）与地塞米松（Ｄｅｘａｍｅｔｈａｓｏｎｅ）联合应用，对体外培养的人翼状胬肉成纤维细胞抑制的结果表明：前两药的给药浓度分别在１０－６Ｍ／Ｌ及３ｇ／Ｌ时，抑制率为５０．４％及６４．３％，均有明显的抑制作用及相应的细胞形态学改变。当高三尖杉酯碱给药浓度为１０－４Ｍ／Ｌ时．其细胞增殖抑制率达９１．８％，镜下基本见不到正常细胞。而当两药分别与地塞米松联合应用时，呈现比单一药物应用时的药量减少而药效增强。 Homoharringtonine and XueShuanTong were combined with Dexamethasone to inhibit the growth of human pterygium fibroblasts in vitro. The results showed that the concentrations of the first two drugs were At 10-6M / L and 3g / L, the inhibitory rates were 50.4% and 64.3%, respectively, with obvious inhibition and corresponding morphological changes of cells. When homoharringtonine administered at a concentration of 10-4M / L. The cell proliferation inhibition rate of 91.8%, the basic microscope can not see the normal cells. When the two drugs are used in combination with dexamethasone respectively, the dosage is lower and the efficacy is better than when the single drug is used.
