顺产与剖宫产产妇初乳中抗感染因子浓度的比较

Compare the concentrations of anti-infective factors of human colostrum between cesarean section and normal labor

目的 比较顺产与剖宫产产妇初乳中抗感染因子含量的差异。方法 采用免疫比浊法测定顺产组及剖宫产组产妇分娩后 4 8、96h共 114份初乳中SIgA、IgG、IgM、补体C3、C4浓度。结果 ①顺产组产后 96h初乳中IgG、C3比产后 4 8h明显降低 (P <0 0 1) ,剖宫产组产后 96h初乳中SIgA、IgG、IgM、G3比产后 4 8h明显下降 (P <0 0 5或P <0 0 1) ;②产后 4 8h剖宫产组初乳中SIgA、IgG、C3、C4浓度明显高于顺产组 (P <0 0 5或P <0 0 1) ;③产后 96h ,剖宫产组C4浓度明显高于顺产组 (P <0 0 5 ) ,其余差异无显著性。结论 产后 4 8h ,剖宫产组初乳中抗感染因子 (SIgA、IgG、C3、C4)

Objective To assess the effect of cesarean section on the composition of breast milk.Methods 114 cases of human colostrum were divided into two groups, normal labor (NL) group and cesarean section (CS) group. And those of both groups on the second day (48th hour) and on the fourth day (96th hour) after paturition were collected and tested for the levels of SIgA, IgG, IgM, C 3,C 4 using the technique of immuno-turbidimetry.Results The study showed that the levels of SIgA, IgG, C 3,C 4 of the colostrum lactating by the CS group were higher significantly than those of NL group at 48th hour after paturition ( P <0.05 or P <0.01). At 96th hour after parturition, the difference was not significant between the two groups except C 4. Conclusion The concentrations of antibodies and complements of human colostrum at 48th hour after parturition of CS group are higher than those of NL group.
