Investigation of the Tiger Milk Medicinal Mushroom, Lignosus rhinocerotis (Agaricomycetes), as an Antiulcer Agent
ABSTRACT
The aim of this study was to determine the antiulcer activity of Lignosus rhinocerotis in rats. A total of 48 Sprague-Dawley rats were used in ethanol-induced, aspirin-induced, and water immersion-restraint stress-induced ulcer models. Rats were equally divided into 4 groups for each model and orally administered 5 mL/kg distilled water, 20 mg/kg omeprazole, as well as 250 and 500 mg/kg of L. rhinocerotis powder. L. rhinocerotis powder at both 250 and 500 mg/kg doses demonstrated significant (P < 0.05) protection against gastric ulceration in all the induced ulcer models. Histological studies revealed severe damage and hemorrhage of gastric mucosa in the negative control group for all ulcer-induced models. The study suggests that L. rhinocerotis powder possesses dose-dependent antiulcer activity in the gastric mucosa, as ascertained grossly and histologically, compared with the negative control groups.
