Stimulation of healing by free radical scavengers of ischemia-induced acute gastric mucosal injury in the rat.


Allopurinol and dimethyl sulfoxide (DMSO; 1 mL of 1, 2, or 5% by gavage daily) were used to examine the influence of scavenging oxygen-derived free radicals on the healing of reserpine- (5 mg/kg, intraperitoneal) and 5-hydroxytryptamine- (50 mg/kg, intraperitoneal) induced acute ischemic injury of the rat gastric mucosa. Allopurinol and DMSO demonstrated a… (More)
