| Summary: | 碩士 === 臺北醫學大學 === 保健營養學系 === 93 === This study was to investigate the effects of synbiotics on the intestinal function and antioxidative status in rats. The male Sprague-Dawley rats were randomly divided into three groups such as control (C), low (L) and high dosage (H) groups (1.56 and 7.80g/kg BW/day synbiotics powder was added to diet). The synbiotics was composed of inulin and 5 probiotics (FloraGuardâ, Viva Life Science). After 8 weeks, rats in L group showed the significantly lower fecal E. coli count than that of control group. The jejunal lactase activity and erythrocytic GRd activity were significantly increased in L group. Rats in H group had higher fecal Lactobacillus and Bifidobacterium and lower E. coli. counts than those of C group. H group also showed the significant increase in jejunal lipase, lactase and isomaltase activities. In addition, the jejunal GRd, CAT and SOD activities, erythrocytic GRd and SOD activities, and hepatic CAT activity were significantly increased in H group.
