Effects of NNAV on the levels of MDA, SOD and GSH. Animals were treated as described in the legend to Figure 1. The blood was collected from abdomen artery and SOD, GSH and MDA were measured in the serum and lung tissue. (A) SOD in the lung tissue. (B) GSH in the lung tissue. (C) MDA in the lung tissue. (D) SOD in the serum. (E) GSH in the serum. (F) MDA in the serum. *P<0.05, compared to control group, #P<0.05, NNAV-treated groups compared to BLM alone group. N =10 per group.
