Abstract:
The serum immunosuppression effect and its relation to oxygen free radicals were studied in patients with thermal injury (n = 11, total body surface area 20%-83%). The serum MDA, sIL-2R increased significantly in burned patients (P < 0.01 all). The serum of burned patients depressed the IL-2 productin of normal human PBMC (P < 0.01). Antioxidants decreased the serum sIL-2R in burned patients and attenuated the suppressive effect IL-2 production of normal human PBMC (P < 0.05 all). The results suggest that oxygen free radicals participate in the serum immunosuppression effect in burned patients.
