Quantification of immunopositive cells a) p53, b) Itgb1, c) Cdk6, d) Nfkb1 and e) Apaf1 in control (C), LPS, high dose without LPS (D10), low dose without LPS (D20), high dose in combination with LPS (DL10) and low dose in combination with LPS (DL20) group. Lung section stained without primary antibody (f) does not show any colour development in airways epithelium and staining with p53 (g) showed immunopositive reaction in airway epithelial (arrow) and septal cells (arrow head). ^a,b no common superscript between two levels of an effect indicates significant difference (p < 0.05)
