Abstract : The purpose of this project is to determine if the immunosuppression which occurs after severe injury can be reversed or prevented by pharmacologic agents. The first step has been to set up defined measures of immunity which reflect postinjury immunosuppression in the mouse. These assays have now been set up; they include T cell subset analysis (blood, lymph node, spleen), T cell mitogenic response with assay for surface antigen expression, neutrophil (PMN) phagocytosis, PMN chemiluminescence, and serum opsonic activity. We are now ready to begin to study the effect of various drugs on these immune functions, which are all inhibited in the injury model. The drugs to be studied in the 3rd year include prostaglandin blockers, histamine-2 antagonists, and cyclophosphamide, an alkylating agent which in low-dose has been shown to inhibit suppressor cell proliferation. Keywords: Trauma, Lymphocytes; Neutrophils; Immunomodulation, Suppressor cells.
