双歧杆菌活菌对肠道菌群及SIgA含量的影响

给３０名健康成人、３０名儿童、１５名血液病患儿、１５名新生儿住院患者服用自行配制的含双歧杆菌的活菌饮料，分析服用前后肠道菌群及ＳＩｇＡ含量，结果提示服用外源性双歧杆菌后，健康成人、儿童、新生儿住院患者肠道内类杆菌数量减少，成人粪便中分泌ＳＩｇＡ的水平上升，儿童肠道内双歧杆菌数量增加，血液病患儿因口服抗生素，肠道菌群及ＳＩｇＡ变化不显著。

The Effect of Drinking Living Bifidobacterial Juice on Intestinal Bacterial Flora and SIgA

Quantitative analyses of intestinal bacterial flora and SIgA were done on a test group of people before and after drinking living Bifidobacterial juice.This test group consisted of 30 adulte.30 children, 15 leukemia childre,and 15 newborn babies. The results showed that after drinking Bifidobacterial juice, the number of intestinal Bacteroides of the abults,children and newborn babies decreased, while SIgA of the adults and the number of Bifidobacteria in the intestine of the childrenrose. The intestinal flora and SIgA of leukemia children did not change noticeably, because they had taken antibiotics orally.
