Figure 5. Soleus muscle weight but not gastrocnemius is normalized following smoking cessation.

BALB/c mice were either exposed to room air or cigarette smoke twice a day, five days a week, for 24 weeks. All mice were then exposed to room air for an additional 60 days, without smoke exposure. Gastrocnemius (A) and soleus (B) muscles were excised and weighted. Results are mean ± SEM of 5 mice. *p<0.05 Room air control mice = Light gray Smoke-exposed mice = Black.
