The rosette inhibition test has been advocated as a test of immune reactivity in patients given transplants. We have done the test in lymphocytes from patients with severe burns, non-burnt control patients, and normal subjects. There was no correlation with the period of immunosuppression which follows a severe burn, though both groups of patients showed a wider range of minimal inhibitory concentrations (M.I.C.) than the normal group. Wide day-to-day variation of M.I.C. in burn and control patients was noted; this seemed to correlate with the ratio of sodium to potassium excreted in the urine. In-vitro experiments suggest that the M.I.C. is correlated with a plasma constituent which may be similar in action to hydrocortisone and that the rosette inhibition test is not a direct measure of immune reactivity.
