Figure 5

Effect of PM014 on the expression of neutrophil elastase and proliferating cell nuclear antigen. Mouse lung sections were stained immunohistochemically. Mouse lung sections were stained with anti-NE goat polyclonal antibody (a) or with anti-PCNA goat polyclonal antibody (b). After the slides were incubated with avidin-biotin peroxidase complex, the color was developed with 3,3′-diaminobenzidine tetrachloride.
