Leukocyte alkaline phosphatase (LAP) activity was studied in 50 women at delivery and in the newborn after delivery. The following findings were observed: (1) the LAP activity of newborns is lower than that of the mothers; (2) significant decrease in the LAP activity has been observed in newborns on the 4th day after delivery; (3) there are no significant differences between newborns from normal and prolonged labor; (4) immediately after delivery the LAP scores of male newborns are lower than those of females, but 4 days later these scores were reversed, and (5) 4 days after delivery, the LAP scores do correlate to the weight of the newborn.
对50名产妇及产后新生儿的白细胞碱性磷酸酶（LAP）活性进行了研究。观察到以下结果：（1）新生儿的LAP活性低于母亲；（2）产后第4天新生儿的LAP活性显著下降；（3）顺产和难产新生儿之间无显著差异；（4）分娩后即刻，男婴的LAP评分低于女婴，但4天后这些评分发生逆转；（5）产后4天，LAP评分与新生儿体重相关。
