Effect of faeces trogopterorum extract B1 on the experimental gastric ulcer and gastric secretion in rats

AIM: To study the effects of extracts B1, B2, and B3 from faeces trogopterorum on the experimental gastric ulcer in rats.METHODS: Two different animal models of gastric ulcers were used in this experiment: Shay''s model (n = 72) and the reserpine-induced ulcer model (n = 76). The total volume and the pH of the gastric juices were recorded. The lesion scores of gastric mucosa were also recorded.RESULTS: The lesion scores of gastric mucosa in the Shay’s model of animals in the WLZ-B₁ groups treated with either 40 g/kg or 80 g/kg were 8.6 ± 10.8 and 1.6 ± 1.9 respectively, which were lower than that of the 0.9% NaCl control group (47.0 ± 31.4, P < 0.05, P < 0.01). The lesion scores for the 80 g/kg group was lower compared to those of the Ran group (20.5 ± 16.4, P < 0.01). The pH of the gastric juices of the 80 g/kg group (3.425 ± 0.143) was higher than that of the 0.9% NaCl group (2.836 ± 0.632, P < 0.05). In the reserpine model, the lesion score of the 40 g/kg group of the WLZ-B₁ (20.7 ± 16.5) was also lower than that of the 0.9% NaCl control group (76.3 ± 50.6, P < 0.05).CONCLUSION: B₁ is the most effective of the three sections in inhibiting gastric secretion, protecting gastric mucosa and preventing experimental ulceration.
