Representative microscopic images of immunohistochemically stained lung sections with anti- iNOS antibody from different experimental groups. a. Control, b. CP and c. ALO + CP groups. Arrowhead refers to the brown coloration of the immuno-positive cells. d. Histogram shows the quantitative and statistical analysis of the changes in the % area of immuno- positive cells from the different experimental groups. Data are represented as the means ± standard error of mean (SEM); analyzed by One-way ANOVA followed by Tukey’s multiple comparisons test. A level of probability (P value) ≤ 0.05 was considered significant. P < 0.05 * compared with the Control group, # compared with CP group
