[Effect of ionol on the stomach lesion in rats during immobilization stress]. / Vliianie ionola na porazhenie zheludka u krys pri immobiliztasionnom stresse.

Intragastric administration of the antioxidant ionol (50 mg/kg/a day) for 7 days did not prevent the formation of ulcers or massive hemorrhages to the gastric mucosa in immobilized animals, increased the number of petechiae and lowered that of erosions. In this case the parietal pH increased in the stomach and dropped in the remaining divisions of the alimentary tract. The combined action of stress and ionol brought about marked hypocoagulation. Ionol exerted a protective action on the stress-induced activation of lipid peroxidation in the stomach but did not produce any such effect on the liver.
