Of view in the point of mother and child nursing, the analysis of the infection protection component of the newborn and the puerpera

1.NAA既含有细支气管组分，又含有肺泡组分，且前者的含量大于碎屑。2.初乳中S-Ig A浓度最高，其次为含漱液、新生儿唾液和NAA。初乳中S-Ig A浓度与产程、羊水破裂至分娩时间及初产妇与经产妇的差异无关。3.NAA中S-Ig A的浓度最低。溶菌酶和乳铁蛋白的浓度比S-JGA高20倍左右。4.在含漱液中，溶菌酶的浓度最低，其次是S-Ig A和乳铁蛋白。血清S-Ig A与乳铁蛋白浓度无差异。尿液中S-Ig A随产程缩短而升高。5.新生儿唾液中S-Ig A浓度在出生后第1天最低，之后逐渐升高。而溶菌酶和乳铁蛋白的浓度则随着出生后第二天的进展而降低。新生儿出生时体重较大，唾液中乳铁蛋白浓度呈下降趋势。

1. NAA contain both tracteobronchial and alveolar components, and their contents of the formers are larger than Tatters. 2. S-IgA concentration in colostrums was highest ascomred with that in gargle liquid, newborn saliva and NAA.S-IgA concentration in colostrums was independent of the during of labor, the time from amniorrhexis to deliver and the difference of primipara and multipara. 3. S-IgA concentration in NAA was lowest as compared with other biological components. Concentrations of lysozyme and lactoferrin were higher about 20 times than s-JgA. 4. In gargle liquid, concentration of lysozyme was lowest as compared with that of s-IgA and lactoferrin. There was no difference between the concentration of s-IgA and lactoferrin. S-IgA in garble liquid increased with shortening the during of labor. 5. Concentration of s-IgA in the newborn saliva was the lowest value at the first day after birth, then increased. On the other hand concentration of lysozyme and lactoferrin decreased with proceeding the day after birth. Concentration of lactoferrin in the newborn saliva tends to reduce as the weight of newborn at the time of the birth was heavy
