From: Multiple exposures to swine barn air induce lung inflammation and airway hyper-responsiveness
Airway smooth muscle quantification. The staining pattern for smooth muscle in controls (A), 1-day (not shown in picture), 5-day exposed (B) and 20-day exposed (C) rat lungs appeared similar. D. The stained area of smooth muscle around the bronchioles was measured using image analyses software. The area of smooth muscle was not significantly different between the groups (P = 0.681).
