[Phagocytic activity by guinea-pig peritoneal macrophages and human peripheral leukocytes irradiated in vitro...

A dose/effect curve for phagocytic activity of guinea-pig peritoneal macrophages and human peripheral leukocytes was determined ranging from anti-inflammatory to immunosuppressive doses. The nitroblutetrazolium reduction test was used stimulating the phagocytes by latex microspheres. A significant enhancement of phagocytic activity by low doses of gamma radiation was observed in guinea-pig macrophages.
