Photomicrographs showing PCNA immunoexpression on the lung tissue of different experimental groups. (A) Moderate immunoreactivity of control group. (B) Negative immunoreactivity of lining epithelium of bronchioles of CP group (arrow). Note that the treated groups with RKs (C) 25 mg/kg, (D) 50 mg/kg, (E) 100 mg/kg and (F) 200 mg/kg were positive; the most intense in the lining epithelium of alveoli of treated group with 200 mg/kg (curved arrow). (G) graph of the mean area % of immunoreaction to PCNA. Results are expressed as mean ± S.E. and analyzed using One Way ANOVA followed by Bonferroni’s post-hoc test at p ≤ 0.05 (n = 4–6). a Indicates significant differences from +control (Control) mice. b Indicates significant differences from CP, c Indicates significant differences from RKs (25 mg/kg/p.o), d Indicates significant different from RKs (50 mg/kg/p.o).
