抚触与不同喂养方式对婴儿体液免疫物质IgG的影响

The influence of touching and different feeding methods on the IgG level of infants

目的研究0～6个月婴儿外周血血清免疫球蛋白IgG的变化规律，并探讨抚触及不同喂养方式对婴儿免疫功能的影响。方法将120例婴儿分为抚触母乳喂养、抚触人工喂养、抚触混合喂养和纯母乳喂养4组，每组30例，纯母乳喂养组为对照组。分别于出生后3，14，42d，3，6个月采外周血，进行放射免疫分析测定血清中IgG的含量。结果随着婴儿出生后天数的增加，其体液免疫物质IgG含量均呈下降趋势，并以母乳喂养抚触组下降速度最慢。在3d时各组间婴儿体液免疫物质IgG含量无显著差异；于婴儿14d后，母乳喂养抚触组婴儿的IgG含量显著的高于其他各组，混合喂养抚触组和人工喂养抚触组婴儿的IgG含量也显著的高于母乳喂养组。结论通过母乳喂养与抚触的干预，可使婴儿自身合成IgG的能力增强，或其消耗速度减慢，从而提高其免疫能力，促进婴儿健康水平。

Objective To study the changing rules of IgG among 0-6 montlxs old infants, and then make sure the influence of touching and different feeding methods on the IgG level of them. Methods Divided 120 0- 6 months old infants into 4 groups randomly, they were the touching and breast feeding group, touching and artificial feeding group, touching and mixed feeding group and the single breast feeding without touching group, there were 30 cases in the each group, the single breast feeding without touching group was the control group. In order to survey the level of IgG, sampling the blood of infants in the point of the third day, the fourteenth day, the forty - second day, the third month and the sixth month. Results The concentration of IgG was decreased according to the infants＇ growing up, the decreased speed in the touching and breast feeding group was slowly than that in the other groups. The concentration of IgG which had sampled in the touching and breast feeding group were all significant higher than those of in the other groups expect the values obtained in the third days. Conclusion Touching and breast feeding can effective improve the concentration of IgG of newborns, and then strengthen the immunity of infants.
