Abstract
Bifidobacterium are frequently used as probiotics, and have been reported to improve intestinal microflora, modulate immune system, modulate blood lipid. This study investigated the effects of yogurt plus fermented with Bifidobacterium longum on intestinal microflora improvement. Sparque-Dawley (SD) rats were fed with 2.135、4.27、8.54 g/kg BW of freezed-dryed yogurt plus fermented with Bifidobacterium longum. Freezed-dryed yogurt plus fermented with Bifidobacterium longum administration 2nd、4th、6th、8th week significantly increased Bifidobacterium spp., Lactobacillus spp., and decreased Clostridium perfringens, Enterobacteriaceae in feces and cecum content. Moreover, increased intestinal transit of active carbon, and decreased lesion index in gastric mucosa of SD rats. These results demonstrated that administration of different dose of freezed-dryed yogurt plus fermented with Bifidobacterium longum has effects on improve intestinal microflora, gastrointestinal motility, prevent gastric mucosal lesion, suggesting that yogurt plus fermented with Bifidobacterium longum has ameliorative effects of gastrointestinal function.
