Abstract : Experiments with two models of intestinal ischemia were performed in order to examine the protective effect of dimethyl sulfoxide (DMSO). Segmental ischemia of the small intestine for 150 minutes caused necrosis of the affected bowel in 90% of the animals. Intravenous administration of DMSO or impregnation of the peritoneum with this substance prevented the development of gangrene in 28 of 29 rats. 30 or 60 minutes of complete ischemia of the small intestine, produced by clamping of the superior mesenteric artery, resulted in partial or complete necrosis of bowel segments with a high incidence of perforation and peritonitis and a high mortality rate within the first 24 hours. Intravenous DMSO, given upon declamping of the artery, effectively protected the bowel from the ischemic damage. There were no deaths among DMSO-treated animals and at 24 h there was no evidence of ischemic damage to the intestine. Through the exact mechanism of action of DMSO is unknown, the results of these and other experiments may warrant clinical trials especially in cases of mesenteric thrombosis.
