PAS staining for the evaluation of mucus production. Results showed that rats pretreated with α-mangostin (AM) at doses of 10 and 30 mg/kg ((c) and (d), resp.) and omeprazole ((e); 20 mg/kg) showed more PAS-positive mucus as compared to those pretreated with only Tween80 (ulcer control group, (b)) (Magnification: 10x).
