PRESERVATION OF NORMAL HUMAN PLASMA IN THE LIQUID STATE. II. COMPARATIVE IN VITRO STUDIES ON THE PHYSIOLOGIC ACTIVITY OF LABILE CONSTITUENTS OF LIQUID AND FROZEN PLASMA 12

Abstract

The therapeutic use of human plasma is now well established (1 to 3). It is available in three preparations, liquid, frozen, and desiccated from the frozen state. The purpose of the present study is an evaluation of liquid and frozen plasma from the standpoint of the stability of certain constituents having important physiological activity.
