In vivo interleukin-1 (IL-1) administration indirectly promotes type II IL-1 receptor expression on hematopoietic bone marrow cells: Novel mechanism for the hematopoietic effects of IL-1. Comparative effects of particulate and soluble glucan on macrophages of C3H/HeN and C3H/HeJ mice. Kinetics of superoxide scavenging by dismutase enzymes and manganese mimics determined by electron spin resonance.
