10例 60 Co源辐射事故受照者眼晶状体的随访观察
远期效应 眼晶状体浑浊 医学随访
2016/1/7
观察 60Co源辐射事故对受照者眼晶状体的远后效应。方法 对河南省1986年至2000年期间发生的4起60Co源辐射事故共10例受照者进行眼晶状体远期医学观察。用复方托吡卡胺充分散瞳后在裂隙灯下检查眼晶状体,记录病变特征。结果 开封事故中"亮"、新乡事故中"梅"分别于照后2、3年出现典型放射性白内障;许昌事故中"许",照后6年出现典型放射性白内障;开封事故中"燕"、郑州事故中"杰"、新乡事故中"天...
基于COⅠ基因的媒介蝇类快速分子鉴定研究
细胞色素C氧化酶亚基Ⅰ基因 蝇类 分类鉴定
2014/10/30
为解决蝇类形态学鉴定的不足,建立基于细胞色素C氧化酶亚基Ⅰ(COⅠ)基因的DNA条形码技术对蝇类进行分子鉴定。方法 选取烟台口岸常见的16只蝇类作为研究对象,形态学鉴定后,取蝇的单后足代表微量组织,提取总DNA。依据资料,选取COⅠ国际通用引物LCO1490:5′-GGT CAA CAA ATC ATA AAG ATA TTG G-3′,HCO2198:5′-TAA ACT TCA GGG TGA...
