ABSTRACT
Anthocleista schweinfurthii is used in the traditional management of
gastro-duodenal ulcers; this led us to evaluate the gastro-cytoprotective
and healing effects of this plant. Anti-ulcer activity of the stem barks
aqueous extract of Anthocleista schweinfurthii (EAS) was evaluated
using five methods: HCl/ethanol; indomethacin - HCl/ethanol;
Absolute ethanol; Pylorus-ligated (acute gastric lesions), and Acetic
acid-induced chronic ulcers in rats. The parameters assessed were
mucus production; gastric ulcer index; pH, acid concentration and
volume of gastric contents. Sucralfate, cimetidine and ranitidine were
used as the reference anti-ulcer drugs. In all cases, oral administration
of EAS (250 and 500mg/kg), dose-dependently, prevented gastric
lesion formation (p
