急性期Vogt-小柳-原田综合征荧光素眼底血管造影的表现

目的分析急性期Vogt-小柳-原田综合征（VKHS）荧光素眼底血管造影（FFA）的表现。方法对11例（21只眼）急性期VKHS患者做详细的眼部检查，并行眼底彩色照相和眼底荧光血管造影等检查。结果全部患者均有脉络膜背景荧光呈斑点状充盈迟缓，2（）只眼后极部和（或）中用部视网膜色素上皮水平呈多发性细小点状荧光素渗漏，如墨渍样扩散并彼此融合，晚期呈大小不等多湖或单湖状高荧光；1只眼视盘表面辐射状毛细血管扩张，荧光素强烈渗漏，盘周线状出血遮蔽荧光；2只眼放射状条形低荧光；视网膜中央血管系统未见受累。结论急性期VKHS的FFA特征为后极部和（或）中周部视网膜色素上皮层多发性渗漏，造影晚期多湖或单湖样荧光素积存。该特征对VKHS早期诊断具有重要作用。

Capillary electrophoresis of FITC labeled amino acids with laser-induced fluorescence detection

FITC labeled amino acids have been separated using a home-built capillary electrophoresis with a laser-induced fluorescence detection (CE-LIF) system. Seventeen peaks can now be generated from the twenty common amino acids. The key conditions lie in the optimization of pH, buffer electrolytes and buffer additives.
