Abstract:
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.
