为了解我国足月儿母乳淀粉酶活性的动态变化规律,测定40例足月顺产儿乳母不同泌乳期及一次喂奶时前、中、后段乳及母血中淀粉酶的活性。结果显示初乳中淀粉酶活性为(9772.37±1.70)IU/L;随着泌乳期的延长,淀粉酶活性逐渐下降;一次喂奶前、中、后段乳中淀粉酶的活性差异无显著性意义;母乳淀粉酶98％为唾液型淀粉酶;母乳中淀粉酶活性高于母血100倍;产妇年龄与母乳淀粉酶活性无显著性相关。提示母乳中含有丰富的淀粉酶,对母乳喂养儿的淀粉消化和潜在的抗感染作用具有积极意义,应向广大群众大力提倡母乳喂养。
In order to understand the dynamic changes of amylase activity in term milk of full-term infants in China, the amylase activity in 40 lactating full-term cows and lactating maternal blood in different lactation periods and in one feeding period were determined. The results showed that the activity of amylase in colostrum was (9772.37 ± 1.70) IU / L. With the prolongation of lactation, the amylase activity decreased gradually. There was no significant difference in the amylase activity in the milk before, during and after feeding ; Milk amylase 98% salivary amylase; amylase activity in breast milk is 100 times higher than maternal blood; maternal age and breast milk amylase activity was not significantly correlated. It is suggested that breast milk is rich in amylase, which has a positive effect on starch digestion and potential anti-infective effect of breastfeeding children. Breastfeeding should be vigorously promoted to the general public.
