Comparative of Neutrophil Elastase (NE) gene expression between different groups in three time points A) Increasing level of NE gene expression in positive control group at 2, 4 and 6 h post exposure, B & C) Increasing level of NE gene expression at 2 and 4 and decreasing at 6 h post exposure in NS & NL groups respectively D) Elevating of NE gene expression at 2 h then decreasing at 4 h and increasing again at 6 h post exposure in NLS group, (p < 0.05 = *, p < 0.01 = **, p < 0.001 = ***, p < 0.0001 = ****)
