Abstract
Daily subcutaneous administration of cortisone acetate (0.2 mg/kg of body weight) sharply enhanced phagocytosis of staphylococci by macrophages obtained from pleural inflammatory exudates. The increase amounted to 50% of the control values. In addition, such hormonal treatment enabled macrophages from adren-alectomized rabbits to phagocytize as actively as macrophages from control animals.
