在某些胃肠道疾病,大分子物质通过肠道上皮的运转增加,而母乳或乳方喂养的婴儿,牛乳清蛋白可引起婴儿急性腹痛。我们应用人α-乳清蛋白(α-LA)做为标记物来研究肠道对大分子物质的吸收。病人及方法婴儿急性腹痛的定义:即正常营养发育婴儿,1周至少有4天无明显诱因的间断性过度哭闹,每天≥3小时并持续≥1周。符合上述定义就诊的足月儿,根据喂养类型将其分两组:第Ⅰ组:41名母乳喂养儿(男19名,女22名),年龄在10天～12周。第Ⅱ组;23名乳方喂养儿(男11A,女12名)年龄在4～12周。对照组无胃肠道紊乱症状的66名小儿,
In some gastrointestinal diseases, macromolecular substances increase through the gut epithelium, while milk-whey protein can cause acute abdominal pain in babies fed breast-milk or milk-fed milk. We used human α-lactalbumin (α-LA) as a marker to study the intestinal absorption of macromolecular substances. Patients and methods The definition of acute abdominal pain in infants: that normal nutrition development of infants, 1 week at least 4 days without obvious incentive intermittent over-crying, ≥ 3 hours a day for ≥1 weeks. Full-term infants who meet the above definition are divided into two groups according to their type of feeding: Group I: 41 breastfed infants (19 males and 22 females) aged from 10 days to 12 weeks. Group Ⅱ; 23 breastfeeding children (male 11A, female 12) aged 4 to 12 weeks. In the control group, 66 infants with no symptoms of gastrointestinal disorders,
