Fig. 2 Release of (A) H2S, (B) MES, and (C) DMS by feces of healthy subjects. Data represent amount of gas released per gram of dry weight of feces over 24 hours of incubation at 37°C. Samples were obtained before BSS treatment (time zero), after 3 and 7 days' BSS treatment, and 5 days after discontinuation of BSS treatment (12 days).

Fig. 3 Effect of different doses of BSS on quantity of (A) H2S, (B) MES, and (C) DMS in the rat cecum. The following quantities of BSS were administered in 100 g of chow: zero (control; ■), 4 mg (▨), 20 mg (▩), 80 mg (▨), and 400 mg (2). Different letters over bars indicate significant differences (P < 0.05).
