儿童乳糖吸收不良的临床与实验研究

本文参考Arola描述的方法对41名健康儿童进行乙醇乳糖耐量试验(LTTE)血、尿半乳糖测定。血半乳糖(B-gal)<0.3mmol/L、尿半乳糖(U-gal)<2mmol/L诊断为乳糖吸收不良(LM)。另采用LTTE尿法和症状反应记分(SRS)法对138名健康儿童和95名急性腹泻小儿做了LM和乳糖不耐症(LI)的研究。结果提示LTTE半乳糖测定法诊断LM可信;健康儿童随年龄增加LM和LI发生率亦增加;轮状病毒肠炎易并发LM和LI。

Clinical and laboratory study on lactose malabsorption in children

Lactose tolerance test with ethanol(LTTE)described by Arola was performed in 41 healthy children and lactose malabsorption(LM)could be diagnosed if blood galactose(B-gal)was less than 0.3 mmol/L or urine galactose less than 2 mmol/L.Then 138 healthy infants and children and 95 children with acute diarrhea were examined for LM or lactose intolerance(LI)with the urine samples of LTTE and symptom-response score(SRS).It was found that LTTE was reliable in the diagnosis of LM ;the incidence of LM or LI increased with the increase of age in children)and RV enteritis was liable to be complicated with LM or Li.
