维生素E琥珀酸酯抑制人翼状胬肉成纤维细胞生长作用的研究

目的: 探讨维生素 E 琥珀酸酯(VES) 对体外培养翼状胬肉成纤维细胞增殖的影响, 寻找辅助治疗翼状胬肉和预防翼状胬肉复发的新方法。方法: 翼状胬肉成纤维细胞原代、传代培养,观察 VES 对细胞生长曲线的影响,四甲基偶氮唑盐(MTT) 法检测不同质量浓度 VES 对细胞增殖的影响。结果: 与对照组相比,VES 使细胞生长曲线下移,用10, 20mg/L VES 处理细胞 2, 4, 7d 后,细胞生长抑制率分别为 33.2%和 46.7%、67.9%和 76.8%、81.7%和 89.3%。MTT 法显示 VES 对细胞增殖抑制作用在一定范围内呈剂量 - 效应依赖性。结论: VES 可有效抑制翼状胬肉成纤维细胞的增殖活性。

Inhibition of human pterygium fibroblasts in vitro by vitamin E succinate

AIM: To study the antiproliferation of vitamin E succinate (VES) on pterygium fibroblasts in vitro and to find a potential agent for prevention and treatment of primary and recurrence pterygium.METHODS: Primary culture and subculture of pterygium fibroblasts were established in vitro ,and different concentrations of VES (0, 10 and 20mg/L) were added to subcultured fibroblasts, respectively. Influence of VES on the growth curve of fibroblast was observed at day 2, 4 and 7 after treatment of VES. 3- 4,5-Dimethylthiazolzyl]-2,5-Diphenyl Tetrazolium Bromide (MTT) assay at 490nm was used to evaluate the effect of the cells proliferation.RESULTS: The addition of VES to culture caused the marked descent of growth curve in comparison with the control group, and the inhibiting rate of 10 and 20mg/L of VES was 33.2% and 46.7%, 67.9%, and 76.8%, 81.7% at day 2,4 and 7, respectively. VES could obviously inhibit the fibroblast proliferation in dose-dependent manner by MTT assay.CONCLUSION: VES can significantly inhibit the proliferation of pterygium fibroblast in vitro.
