Effects of oral administration of KRG and KRG-P on mouse IgA production. (A) Five BALB/c mice per group were orally and daily administered with the indicated doses of KRG or KRG-P for 10 days. Bodyweight was estimated every two or three days. (B,C) Mouse fecal samples were collected on days 5 and 11 and analyzed for IgA expression by using mouse ELISA assays. (D) The mice were sacrificed at 11 days after oral treatment, and tissues from the jejunum region of the small intestine were then collected. Intestinal IgA mRNA levels were measured using qRT-PCR. Data are presented as the means ± SD of three independent experiments. * p < 0.05 vs. the normal group. ** p < 0.01 vs. the normal group.
