Abstract
We studied the effect of in vivo ozone inhalation (3 ppm, 2 h) on neuroreceptor function in guinea pig tracheal smooth muscle in vitro and the role of the epithelial layer in this process. Changes in smooth muscle tension after stimulation of the muscarinic- and β-adrenergic receptor were recorded isometrically and stained tracheal tissue sections were histologically evaluated for changes in the epithelial and smooth muscle layer. Ozone exposure resulted in an increase in maximal contraction following stimulation of the muscarinic receptor, whereas pD
