The Effect of Typhoid Vaccine Injection of Partial Body Irradiated Rats

Abstract
Typhoid vaccine was injected into partial body irradiated rats in an attempt to elucidate the mechanism of irradiation induced leupopenia. Upper body irradiation predominantly damages intravascular leucocytes. Lower body irradiation depresses the release of leucocytes from the bone marrow and also damages intravascular leucocytes, but to a lesser degree than upper-body irradiation.
