【摘要】 目的试比较醋酸铅氢氧化铵法和PH还原糖法(改良班氏法)在婴幼儿粪便乳糖定性检测中的应用。方法对192例腹泻病的婴幼儿的粪便用两种方法对其作定性检测乳糖含量。结果用醋酸铅氢氧化铵法检测乳糖比PH还原糖法的检出率阳性高。P<0.001,两种方法具有显著性差异。结论用醋酸铅氢氧化铵法检测粪便乳糖具有很好的特异性、敏感性;操作简易、方便、价廉而试剂全国均有销售,所以醋酸铅氢氧化铵法检测大便乳糖易于全国各级医院进行开展。更多还原

【Abstract】 objective The purpose is to compare plumbum acetate and ammonia hydroxide method with the PH and reduction lactose method on application of qualitative lactose measurement in babies’ excrement. Methods lactose were measured qualitatively in 192 babies’ excrement by two methods. Results Positive rate of plumbum acetate and ammonia hydroxide method is significantly higher than that of PH and reduction lactose method (P<0.001). Conclusions Plumbum acetate and ammonia hydroxide method special, sensitive; and the operation is simple, convenience. Cheap reagent can be bought in whole country. So qualitative lactose measuring by plumbum acetate and ammonia hydroxide method is easily popularized in hospitals.更多还原
