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含有气管支气管和肺泡两种成分，气管支气管成分含量大于肺泡成分。2.初乳中S-IgA含量最高，其次为漱口液、新生儿唾液和NAA，且与产程、羊水破裂至分娩时间及经产妇的差异无关。3. NAA中S-IgA含量最低。溶菌酶和乳铁蛋白的浓度比s-JgA高约20倍。4.含漱液中溶菌酶含量最低，其次是s-IgA和乳铁蛋白。s-IgA和乳铁蛋白的浓度之间没有差异。产程越短，羊水中S-IgA含量越高。5.新生儿唾液中s-IgA浓度在生后第1天最低，以后逐渐升高。而溶菌酶和乳铁蛋白的含量则随日龄的增加而降低。新生儿唾液中乳铁蛋白的浓度随着新生儿出生时体重的增加而降低

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
