【摘要】 为研究分娩方式是否影响新生儿免疫状态,检测和比较了68例妊娠足月阴道产和64例妊娠足月剖宫产分娩的新主儿脐血C₃、C₄及IgG、IgA、IgM的含量,其结果;IgG的含量阴道产组明显高于剖宫产组（P<0.05）,且男婴阴道产组IgG的含量明显高于剖宫产组（P<0.05）.说明剖宫产可以降低新生儿免疫应答及抗感染能力.阴道分娩使新生儿从母体获得抗体,男婴比女婴更为重要.更多还原

【Abstract】 In order to investigate whether the delivery modes affected the immunity function in the neonate,immunoglobulins A, G,M and complements C3, C1 were measured in 64 cases of normal pregnant Women delivered vaginally and 68 cases of normal pregnant women delivered by cesarean section. The results showed that the level of IgG was significantly higher in the group delivered vaginally than that delivered by cesarean section (P<0. 05).The research make a conclusion that cesarean section might diminish the immunity function of neonate. The vaginally delivery mode let the neonate get the antibody from the body of his mother,especially in the males.更多还原
