Abstract
In alloxan-diabetic rats fed constant and adequate amts. of food, admn. of purified growth hormone in amts. of 3-5 mg./100 g./day for several days was accompanied by increased excretion of glucose. After cessation of treatment, glycosuria in some cases receded, or in others remained high for some time. In some susceptible animals, a single injn. of growth hormone was followed by persistent elevation of the blood glucose level.
