In the absence of stomach and gastric acid, the damaging effects of cysteamine (400 mg/kg s.c., sacrifice 24 hours thereafter), so far thought to be an acid related duodenal ulcerogen, and the cytoprotective effects of NaBPC157 (10 g or 10 ng/kg i.p.) were further challenged in comparison with reference agents (cimetidine (50), ranitidine (10), omeprazole (10), bromocriptine (10) and atropine (10) (values given in mg/kg i.p., 1 hour before cysteamine)) known also to be cytoprotective

This is supported by the strong positive correlation between the changes in the expression of 45 genes 1 h after the Selank or GABA administration
