Purpose: In order to improve the preparation method for barium examination of the stomach by ranitidine and acetylcysteine use, the effect on the rat gastric mucosa caused by the administration of ranitidine and acetylcysteine was studied. Materials and Methods: Rat stomach that had been treated with ranitidine or acetylcysteine at different intervals and examined in vivo was excised and coated with a barium suspension. A radiograph was subsequently taken and evaluated in regard to the removal of gastric mucus and imaging of the areae gastricae (AG). The removal of mucus was assessed by six blind observers. The imaging of AG was estimated as a percentage of the imaged AG area per total gastric corpus. Results: No change was seen on the radiograph with ranitidine preparation, while the mucus was distinctly removed and AG well-imaged in the group studied 15 minutes after the peroral administration of acetylcysteine. Conclusion: Proper preparation for barium study of the stomach should involve treatment with a mucolytic agent about 15 minutes before the examination. H2-blockers must be used supplementally in the short term.
