Abstract
Gastric acid secretion in response to meals of infant formula was studied in 8 healthy infants aged 4 to 24 weeks. The technique involved intragastric volume determinations using a marker and measurement of the acidity of the gastric contents. In the 2-hour postprandial period, pH declined from 7 to 5.2. The one-hour postprandial gastric acid output was 236 +/- 49 mumol/kg body weight.
摘要
对8名年龄在4至24周的健康婴儿进行了研究，观察其摄入婴儿配方奶后胃酸分泌情况。该技术包括使用标记物测定胃内体积以及测量胃内容物的酸度。在餐后2小时内，pH值从7降至5.2。餐后1小时的胃酸分泌量为236±49微摩尔/千克体重。
