Figure 6.

Protein expression of Bcl-2 extracted from the peripheral blood PMNs of rats in the different groups. The upper panels are Western blots, and the lower panels are summaries of the densitometric analysis of Bcl-2 protein expression in the different groups. Control, control group; LPS, LPS administration group; LPS+SO₂-1, pretreatment with 10 μmol/L SO₂ before LPS administration; LPS+SO₂-2, pretreatment with 20 μmol/L SO₂ before LPS administration; LPS+SO₂-3, pretreatment with 30 μmol/L SO₂ before LPS administration. Data are shown as the mean±SD (n=6 rats in each group). ^bP<0.05 compared with the control group; ^eP<0.05, ^fP<0.01 compared with the LPS group.
