[Effect of adrenaline and hydrocortisone on thiamine absorption in the intestine]

The effect of a single intramuscular injection of adrenalin and hydrocortisone (0.5 mg/kg and 10 mg/kg, respectively) on the thiamine absorption was studied in an isolated part of the intestine in male albino rats. The hormonal action on the Na-K-ATPase activity in the intestinal mucosa was also investigated. The intestinal thiamine absorption rate was shown to increase 10 min after adrenalin and 60 min after hydrocortisone injection. The Na-K-ATPase activity in the intestinal mucosa rose 10 min after the adrenalin injection and did not change after the administration of hydrocortisone.
