Comparison of BAL fluid neutrophil counts per mm3 in each group. Contusion resulted in a significant increase in neutrophil population (p = 0.003). Contusion-induced neutrophil increase was reduced significantly by Dxm. administration compared to sham group (p = 0.016). *: p < 0.01 compared Group I, Mann whitney U test. †: p < 0.05 compared Group II, Mann whitney U test. Group I: control. Group II: contusion (sham). Group III: contusion + CoQ10. Group IV: contusion + vitamin C. Group V: contusion + vitamin E. Group VI: contusion + dexamethasone.
