ABSTRACT

<p><b>OBJECTIVE</b>To explore the mucosal protective effect on the quality of gastric ulcer healing.</p><p><b>METHODS</b>Gastric ulcers were induced in male rats by serosal application of acetic acid. Rats were gavaged for 14 days with saline, omeprazole (OME), teprenone (TEP) and TEP plus OME starting 3 days after ulcer induction. Then the tissues and blood samples were obtained and measured.</p><p><b>RESULT</b>The lower ulcer index (UI) and increased ulcer inhibition rate were observed in OME and OME+TEP groups. In TEP and OME+TEP groups, restored mucosa thickness increased, cystically dilated glands decreased, microvessels in connective tissue increased, the secretion of mucus, hexosamine, PGE(2), bFGF were enhanced, the expression of EGFR was increased.</p><p><b>CONCLUSION</b>TEP can improve the quality of gastric ulcer healing, when combined with OME,the effect is more marked.</p>
