甲硝唑与护理液对棘阿米巴原虫体外杀伤效果的评估

摘要

目的:分析6种角膜接触镜多功能护理液和加入甲硝唑滴跟液的护理液对自生生活性棘阿米巴原虫的杀伤效果.方法:将6种多功能护理液分别加入96孔板中,每种护理液占用48孔,其中24孔滴入阿米巴悬液,另外24孔先滴入甲硝唑滴眼液后再滴入阿米巴悬液,室温静置8h后在倒置显微镜下观察残存阿米巴的形态变化和数量.将残存的棘阿米巴原虫分别在PYG培养液中培养5d,观察其形态、活性与增殖能力的变化.结果:单纯护理液组1-6号阿米巴检出率分别为0%、80.3%、29.1%、41.7%、62.5%、79.2%,加入甲硝唑滴眼液后护理液1-6号阿米巴检出率分别为0%、0%、4.2%、8.3%、16.7%、16.7%,3-6号护理液加与不加甲硝唑滴眼液杀伤阿米巴的效力差异有统计学意义(3-6组的X2值分别为3.75、7.11、10.54和18.78,P＜0.05).残存的棘阿米巴原虫经培养后活力与增殖力减弱.结论:部分多功能护理液对棘阿米巴原虫的杀伤效果不佳,添加甲硝唑滴眼液后杀伤效果明显提高.%AIM:To analyze the killing efficiency of six kinds of contact lens solutions and solutions with arilin on free living Acanthamoeba culturedin vitroMETHODS:Six kinds of contact lens solutions were added into 96-well microtiter plates,respectively,with each care solutions used 48 holes of them.Suspension of Acanthamoeba were added into 24 of these holes.and arilin gutta and suspension of Acanthamoeba were added into the other 24 holes.After standing in room ternperature for 8 hours,the morphologic change and quantity of the remnant Acanthamoeba were observed under the jnverted microscope.The remnant Acanthamoeba were cultivanted in peptone-yeast extract-glucose (PYG)-culture medium for 5 days.Their variation of appearance,activity and reproductive activity were observed.RESULTS:In the six experimental groups using contact lens solutions only.the detection rate of Acanthamoeba of were 0%,80.3%,29.1%,41.7%,62.5% and 79.2%,respectively.After arilin was added,the detection rate of Acanthamoeba of the six groups were 0%,0%,4.2%,8.3%,16.7% and 16.7%,respectively.From group 3 to group 6,after arilin was added,the differences of the killing efficiency of contact lens solutions have statistical significance(X2=3.75,7.11,10.54 and 18.78;P＜0.05).Cultivation of the remnant Acanthamoeba showed a reduction in the activity and proliferative ability.CONCLUSION:The killing efficiency of some contact lens solutions on free-living Acanthamoeba were not satisfying.Arilin can improve the killing efficiency of contact lens solutions.
