Small intestinal lactase, sucrase and alkaline phosphatase activities were measured in histologically normal peroral intestinal biopsies from 477 individuals. Enzyme activities varied with age, sex, site of biopsy, and were lowest in post-weaning children and highest in young adults. Lactase activity does not decrease with advancing age.
对477名个体的组织学正常的经口肠道活检样本测定了小肠乳糖酶、蔗糖酶和碱性磷酸酶活性。酶活性随年龄、性别、活检部位而变化,在断奶后儿童中最低,在年轻人中最高。乳糖酶活性不会随着年龄增长而降低。
