Effects of Dietary Fiber on the Bacterial Enzymes and Putrefactive Metabolite in Aged Rats

주요 식이섬유질원이 첨가된 식이가 노화 흰쥐의 장내효소 및 유해산물에 미치는 영향

This study was performed to investigate the influcence of various dietary fiber sources in Korea for activities of bacterial enzymes (${\beta}$-glucosidase, ${\beta}$-glucuronidase) and amounts of putrefactive product (indole) in aged rats. ${\beta}$-Glucosidase activity in the intestinal content was significantly lower in the seamustard 15% group than in other groups whereas the activity of ${\beta}$-glucuronidase was higher in the mugwort 15% group than other experimental groups. The amount of indole and pH in the intestinal content of aged rats were significantly lower in mugwort groups than in other groups.
