Fig. 3From: Role of airway smooth muscle cell phenotypes in airway tone and obstruction in guinea pig asthma modelGSH changes in isolated airway smooth muscle cells from a guinea pig asthma model. a Levels of GSH in isolated myocytes. Scatter graphs showing that GSH levels were correlated (b) directly with changes in the PD200 ratio (upper panel) and inversely with Rmax values (lower panel). *P = 0.0064 compared with the control (unpaired Student’s t-test). r = Spearman correlation coefficient; P = paired Student’s t-testBack to article page
