It is known that there is a close relationship between cigarette smoking and peptic ulceration. Epidemiology studies showed that cigarette smokers were found to have more ulcers and they were usually healed slower but relapsed faster. However, which ulcerogenic substances in cigarette smoke are responsible for sucy actions and also the mechanisms by which cigarette smoke affects ulcer formation and healing, are still undefined. Therefore the purposes of this study are to isolate and identify this substance(s) and study how this substance(s) affects ulcer formation and healing.
