Abstract

The effect of hypophysectomy on glucose and galactose absorption from the small bowel was studied in young rats. In vitro studies were performed on intestinal rings, and in vivo studies were done on jejunal loops. Glucose and galactose absorption was found to be increased in hypophysectomized rats, both in vitro and in vivo, 5 days after hypophysectomy, but these levels returned to the control range 11 days after surgery. Conversion of glucose-1-14C to14CO2, by small bowel rings obtained from hypophysectomized rats 5 days after surgery, was found to be enhanced. These observations suggest that, soon after hypophysectomy, glucose is metabolized at a higher rate by the intestine.
