THE EFFECT OF LACTOGENIC HORMONE PREPARATIONS ON THE BLOOD SUGAR LEVEL OF RABBITS AND MONKEYS

Abstract

Daily injection for 4-7 days in 4 monkeys of preparations of the anterior pituitary lactogenic hormone believed to be relatively free of the other known pituitary principles produced no blood sugar rise and no gtycosuria (other less purified extracts raised sugar in blood and urine). Similar injections of 0.5-3 rabbit units daily of the purified hormone in 13 pseudopregnant and 6 estrous rabbits produced no significant alteration in the blood sugar level and no glycosuria. The pseudopregnant rabbits, whose mammary glands were well developed, lactated profusely while the estrous animals showed only a scanty secretion.
