| 1 | Comparison of pre-treatment and post-treatment use of selenium in retinal ischemia reperfusion injury显示文摘AIM: To investigate the effects of selenium in rat retinal ischemia reperfusion(IR) model and compare pretreatment and post-treatment use.METHODS: Selenium pre-treatment group(n =8) was treated with intraperitoneal(i.p.) selenium 0.5 mg/kg for7 d and terminated 24 h after the IR injury. Selenium posttreatment group( n = 8) was treated with i. p. selenium0.5 mg/kg for 7d after the IR injury with termination at the end of the 7d period. Sham group(n =8) received i.p.saline injections identical to the selenium volume for 7d with termination 24 h after the IR injury. Control group(n =8) received no intervention. Main outcome measures were retina superoxide dismutase(SOD), glutathione(GSH),total antioxidant status(TAS), malondialdehyde(MDA),DNA fragmentation levels, and immunohistological apoptosis evaluation.RESULTS: Compared to the Sham group, selenium pre-treatment had a statistical difference in all parameters except SOD. Post-treatment selenium also resulted in statistical differences in all parameters except the MDA levels. When comparing selenium groups, the pre-treatment selenium group had a statistically higher success in reduction of markers of cell damage such as MDA and DNA fragmentation. In contrast, the post-selenium treatment group had resulted in statisticallyhigher levels of GSH. Histologically both selenium groups succeeded to limit retinal thickening and apoptosis. Pre-treatment use was statistically more successful in decreasing apoptosis in ganglion cell layer compared to post-treatment use.CONCLUSION: Selenium was successful in retinal protection in IR injuries. Pre-treatment efficacy was superior in terms of prevention of tissue damage and apoptosis. | Alper Yazici Hasan Aksit Esin Sogutlu Sari Arzu Yay Haydar Ali Erken Dilek Aksit Harun Cakmak Kamil Seyrek Sitki Samet Ermis | 2015 | International Journal of Ophthalmology(English edition)2015，8，2： | 3 |
| 2 | CSCR中盐皮质激素受体基因-2G/C的多态性及其与血浆皮质醇水平的关系(英文)显示文摘目的:评估中心性浆液性脉络膜视网膜(CSCR)病变中盐皮质激素受体基因-2G/C单核苷酸多态性,以及基因多态性和血浆皮质醇水平的关系。方法:选取60例中心性浆液性脉络膜视网膜病变患者和50例正常人作为研究对象。患者皆患有急性中心性浆液性脉络膜视网膜病变,即浆液性视网膜脱离和视网膜色素上皮脱离或功能障碍(排除其它可能导致渗出的疾病,比如脉络膜新生血管、炎症或浸润病变)。为避免皮质醇水平的昼夜变化,上午8时到10时之间采集外周血样,检测盐皮质激素受体基因多态性(rs2070951)和血浆皮质醇水平。结果:CSCR组的基因型频率分布为G/C(46.6%),G/G(26.7%)和C/C(26.7%)。两组间基因型分布无统计学差异(P=0.96)。研究结果显示,CSCR组的血浆皮质醇水平为401.2±162.1 nmol/L,对照组为296.8±130.1nmol/L,两组间差异有统计学意义(P<0.01)。血浆皮质醇水平在G/C(345.0±137.0 nmol/L),G/G(369.2±165.3 nmol/L)和C/C(395.3±188.8 nmol/L)基因型之间不存在差异(P=0.50)。结论:盐皮质激素受体基因多态性与中心性浆液性脉络膜视网膜病变和血浆皮质醇水平无关。 | Alper Yazici Esin Sogutlu Sari Betul Eser Gozde Sahin Medine Alpdemir Adil Kilic Muhammet Kazim Erol Sitki Samet Ermis | 2016 | 国际眼科杂志2016，16，7： | 0 |
