Allogeneic blood transfusion (Allo/BT) and burn injury modify the cellular immune response in patients under a variety of circumstances. We designed this study to investigate the influence of Allo/BT, burn injury, and the combination of the two on in vivo natural killer (NK) cell activity in a murine model. This study demonstrated significant enhancement of in vivo NK cell activity in noninjured BALB/c mice receiving Allo/BT from C3H mice when compared to both the control and syngeneic blood transfusion group at posttransfusion day 5. When burn-injured mice were compared to sham-stressed mice, the burn-injured mice showed significant suppression of in vivo NK cell activity. Furthermore, in this strain combination model, Allo/BT modulated the suppressive effect of burn injury on in vivo NK cell activity at posttransfusion day 5 and postburn day 7.
