Experiments were designed to examine whether inhibition of the renin-angiotensin system alters gastric mucosal damage in conscious rats subjected to restraint. Two hours immobilization resulted in an ulcer index of 46 +/- 4 (n = 16) which was decreased by converting enzyme inhibitor (MK 422, enalaprilat) doses of 1 and 10 mg.kg-1.h-1 by 50 +/- 16 (n = 8) and 66 +/- 8% (n = 13), respectively (p < 0.05). Gastric blood flow measured by both the 99Tc-labelled frog erythrocytes and 86Rb-clearance methods was low in untreated rats and increased to more than three-fold in angiotensin converting enzyme inhibitor treated animals. Infusion of saralasin a specific angiotensin II receptor blocker (5 micrograms.kg-1.h-1, n = 25) also decreased the ulcer index by 40 +/- 5% (p < 0.05). Thus inhibition of the renin-angiotensin system in conscious cold-restraint rat increased gastric blood flow and reduced mucosal damage. These results suggest that the renin-angiotensin system plays a significant role in the development of experimental gastric ulcer in the cold-restraint model.

Microscopic colitis (MC) is a disease with intestinal mucosal inflammation causing diarrhea, affecting predominantly middle-aged women. The etiology is unknown, but increased prevalence of autoimmune diseases in these patients has been described, although not compared with controls or adjusted for confounding factors. The aim of this study was to examine the prevalence of common diseases in patients with MC and controls from the general population. Hypertension, rheumatoid arthritis, asthma or bronchitis, ischemia, and diabetes mellitus were more prevalent in patients than in controls. The prevalence of gastric ulcer and cancer did not differ between the groups. Besides corticosteroids, many patients were also being treated with proton pump inhibitors, antidepressant drugs, angiotensin-converting enzyme inhibitors or angiotensin II receptor antagonists, statins, thyroid hormones, and beta-blockers. More patients than controls were former or current smokers (72.5% versus 57.7%). Thus, MC patients have an increased prevalence of several diseases, not only of autoimmune origin.
