Cell apoptosis in lung tumor tissues of rats in each group

Note: A, Representative sections stained for apoptosis by TUNEL assay; B, The cell apoptosis rate in lung tumor tissues in each group; C-D, The protein expressions of Bax, Caspase-3, and Bcl-2 in lung tumor tissues of rats in each group detected by Western blotting. Same letters showed no significant difference, P>0.05; Different letters showed statistically significant difference, P<0.05.
