摘要
目的:探讨地塞米松对小梁细胞bcl-2基因表达的影响。方法:应用组织块培养的方法建立人小梁细胞培养。取第三代小梁细胞培养于载玻片上,含10^(-7)mol/L地塞米松的培养液作用6小时、12小时、24小时后,应用LSAB观察bcl-2基因表达的情况。结果:地塞米松作用6小时后可见bcl-2蛋白阳性细胞,且随时间的延长,阳性细胞有所增多。结论:地塞米松可诱导小梁细胞bcl-2基因表达,可能在激素性青光眼发病中起着一定的作用。眼科学报1998;14:187～189。
Purpose:To investigate the influence of dexamethasone on expression of bcl-2 gene in human trabecular cells.
Methods: The trabecular specimens from human eyes were cultured in vitro and the cultured cells of the third generation on slides were immersed in culture solution containing 10-7M dexamethasone for 6 hours, 12 hours and 24 hours respectively. The expression of bcl-2 gene was studied with LSAB.
Results: The positive cells of the bcl-2 protein could be identified after dexamethasone effected for 6 hours and the positive cell increased with time going on. Conclusion :The expression of bcl-2 gene can be induced by dexamethasone, it may be related with glaucomatic pathogenesis. Eye Science 1998 ; 14 ; 187 - 189.
