Figure 2: Effect of CBS on colonic myeloperoxidase (MPO) activity of mice. Colitis was induced by administration with 5% dextran sulfate sodium (DSS) for 7 d. CBS (50 and 150 mg/kg) was administered daily for 7 d, respectively. MPO activity was determined using an MPO detection kit. Data are presented as mean ± SD of eight mice per group. versus control, versus DSS alone, and versus CBS 50 mg/kg.
