Leukocyte counts and lymphocyte subpopulations were measured in umbilical cord blood obtained from normal pregnancies delivered either vaginally or by elective cesarean section. In the group delivered vaginally there were significantly higher median values for neutrophils, monocytes, and natural killer cells. The leukocytosis associated with labor is selective for mediators of nonspecific or innate immunity. Labor may be an immunologically beneficial process for the neonate.
对经阴道分娩或择期剖宫产的正常妊娠产妇的脐带血进行白细胞计数和淋巴细胞亚群检测。在经阴道分娩组中，中性粒细胞、单核细胞和自然杀伤细胞的中位数显著更高。与分娩相关的白细胞增多对非特异性或先天性免疫介质具有选择性。分娩对新生儿可能是一个免疫有益的过程。
