  • Title: On the biochemical background of cimetidine's anti-ulcerogenic effect in the rat.
    Author: Bálint GA.
    Journal: Acta Physiol Hung; 1991; 77(2):153-8. PubMed ID: 1656700.
    Abstract:
    It was published earlier that during gastric ulceration an elevation in the antral and fundic mucosal cAMP/cGMP ratios can be encountered in rats. This phenomenon was interpreted as a probable sign of the reparative, antiulcerogenic processes. This assumption received further evidence when the experimental animals were treated with prostacyclin. According to the present investigations the H2-receptor blocker cimetidine, in such small dose which does not interfere with the gastric acid secretion, evoked the same cAMP/cGMP ratio elevating effect. On the basis of the performed investigations the questions raised, namely: Does the cytoprotective (anti-ulcerogenic) effect of different drugs have a common molecular basis in the (rat) gastric mucosa? If so, what is the possible role of the mucosal cyclic nucleotides in this process? Further studies are being needed in this field to clarify all details.
