  • 简介:目的:探讨线粒体膜电位(△ψm)、Caspase3在As2O3诱导ACC-2细胞凋亡中的作用。方法:进行ACC-2细胞培养,将As2O3建立不同药物浓度梯度(0,1.0,2.0,4.0,8.0μmol/L)分别作用于ACC-2细胞,用Rh123染色,流式细胞仪检测8.0μmol/LAs2O3作用前、后(24h),ACC-2细胞的线粒体膜电位(△ψm)变化;用多功能酶标仪进行Caspase3活性检测。结果:空白对照组ACC-2细胞内Rh123荧光强度最强,8.0μmol/LAs2O3处理组ACC-2细胞内Rh123荧光强度减弱,其差异有显著性(P〈0.05);随着As2O3药物浓度的增高(0,1,2,4,8μmol/L),ACC-2细胞的Caspase3酶活力单位逐渐增加。结论:As2O3作用于ACC-2细胞,可通过降低线粒体膜电位从而引起细胞凋亡。随着As2O3药物浓度的增高,ACC-2细胞的Caspase3酶活力单位逐渐增加,Caspase3被激活,细胞可发生不可逆转的凋亡过程。

  • 简介:目的探讨听神经瘤误诊为眼科疾病的临床因素。方法对2004.5-2005.5首诊于我科的听神经瘤病例误诊情况进行回顾性分析。结果由于该病情发展缓慢,早期症状为非特异性;临床眼科医生对此病认识不足;缺乏系统、针对性检查等是导致误诊的主要原因。结论临床眼科医师应了解此病临床特点及眼科可能出现的体征,全面、细致检查是减少误诊有效方法。

  • 简介:目的探讨批量白内障复明手术中眼内炎的防治方法。方法回顾性分析我院2007~2010年完成的1174例贫困白内障患者复明手术中3例并发眼内炎的患者的治疗过程和结果。结果1174例贫困白内障患者复明手术中3例并发眼内炎,发病率为0.26%。经过结膜下及玻璃体腔注射万古霉素,2例感染被控制,视力分别恢复到0.12和0.2,1例眼球萎缩。结论批量白内障复明手术需要医生术前严格筛查病人,严格掌握手术适应症;提高手术技能,缩短手术时间;发生眼内炎后应积极救治,及时行玻璃体腔注射抗菌素,尽早行玻璃体切割术,以挽救患者的视力。

  • 简介:白内障是最常见的致盲眼病之一。谷胱甘肽S转移酶(glutathioneS-transferases,GSTs)是典型的多功能酶,主要催化各种化学剂与谷胱甘肽结合。近些年的研究表明,GSTs有抗过氧化引起的白内障作用。GSTs表达水平的高低在白内障形成中有着重要的作用。我们将近年来GSTs与年龄相关性白内障的研究情况做一综述。
