M ethods 1. 30 health subject s ( 15 male 15 f emale) were randomly selected from the clinic of Tianjin CDC . They w ere provide 15 g Isom altooligosaccharides once a day for 7 days; 2. 4 0 BABLc mice w ere divided into 4 groups 3 ex perimental groups and 1 control group . These 3 experimental groups w ere f ed different dose of Isomaltooligosaccharides by gavage f or 7 days. Feces of both human and mice were determ ined before and at the end of the experiment . Result s The re sult s show ed that the reproduction of Bif idob acteria and Lactobacillus greatly increased and the growth of Clostridium per friengenes w as significantly inhibited b
