[Healing of gastric mucosal erosions induced by indomethacin and restoration of glucocorticoids levels in the blood of rats].

The study was made of the effects of low production of glucoorticoids and subsequent replacement with these hormones on healing of hemorrhagic erosions of rat gastric mucosa emerging 4 hours after administration of indomethacin (25 mg/kg percutaneously). Corticosteroid deficiency was produced by adrenalectomy or blocking function of the hypothalamo-hypophyseo-adrenocortical system by introduction of supraphysiological dose of hydrocortisone i week before indomethacin administration. Replacement therapy was conducted 4 hours after indomethacine administration by subcutaneous injection of corticosterone in a dose of 4 mg/kg. Healing was evaluated by changes in the area of damaged surface of gastric mucosa for 2 days after indomethacin administration. Plasma levels of corticosteroids were controlled. It was found that animals with corticosteroid deficiency had a larger area of mucosal lesion and slow healing vs control rats. Administration of corticosterone in physiological dose to animals with deficient production of corticosteroids stimulated healing of gastric mucosa erosions.
