目的:更好地阻断和控制肝吸虫病的传播和流行,研究何种浓度的乙醇溶液对杀灭肝吸虫囊蚴更有效。方法:分组(囊蚴50/个组),将囊蚴置于等量(0.5 ml)不同浓度(体积分数25%、50%、75%、95%)乙醇中,分别作用不同时间,显微镜下观察囊蚴的活动情况,设立对照组。结论:低(25%)、中(50%)、高(95%)浓度的乙醇溶液对肝吸虫囊蚴的杀灭作用弱,较高浓度(75%)乙醇溶液杀灭作用较好,但白酒的乙醇含量均不到70%,因此,白酒对肝吸虫没有杀灭作用。
OBJECTIVE: To better block and control the spread and prevalence of clonthiasis and to study which concentrations of ethanol solutions are more effective at killing metacercariae of liver flukes. Methods: The metacercariae were placed in different concentrations (25%, 50%, 75%, 95%) of ethanol in equal volume (0.5 ml) Observation of the activity of metacercaria, the establishment of the control group. CONCLUSION: The killing effect of the low (25%), medium (50%) and high (95%) ethanol solution on metacercariae of liver flute is weak, but the killing effect of higher concentration (75%) ethanol solution is better, Alcohol content of less than 70% of liquor, therefore, white wine does not kill liver fluke role.
