The influence of partial resection of the small intestine on the pituitary gland.
Starting from the observations of other investigators according to whom massive resection of a portion of the small intestine brings about compensatory changes in the remaining intestine, the existence of a feed-back mechanism between the small intestine and the pituitary gland is postulated. The weight and histologic aspect of the pituitary gland were studied after resection of 50 cm jejunum in the white rat. The results showed increase in the weight of the pituitary and histologic signs of hyperactivity in the anterior lobe.
