FOR more than a year we have been engaged in a study of the inactivation by enzymes of purified preparations1 of the oxytocic principle of the pituitary gland. The stimulating action of the hormone on smooth muscle is slowly destroyed by aminopolypeptidase preparations from English brewers' yeast, and is rapidly destroyed by dipeptidase and proteinase… CONTINUE READING
