Influence of negative air ions on experimental ulcer induced by pylorus ligature in albino rat.

The authors studied the influence of negative aeroionotherapy (AIT) on the gastric ulcer induced by pylorus ligature. After 24 hours the ligature was removed and the stomach was studied with respect to number and aspect of ulcers (hemorrhagic or not), periulcerous mucosa (edema, folds), acidity and microhemorrhage of gastric secretion. The animals were divided into 4 groups: C1 and C2 (controls)--not treated with air ions; P--prophylactically exposed 10 days before the operation to AIT; T--submitted to AIT prophylactically 10 days before the operation--therapeutically 5 days after operation. The results showed a favourable influence of AIT: the number of gastric ulcers was smaller; the regeneration processes in the mucosa were ameliorated; the gastric acid secretion and microhemorrhage diminished.
