Figure 3From: Immune sensitization of equine bronchus: glutathione, IL-1β expression and tissue responsivenessEffects of passive sensitization and reduced-glutathione (G; 100 μM) on contraction induced by electrical field stimulation in equine isolated bronchi. Values are expressed as percentage of ACh (100 μM) induced contraction and are mean ± SEM of four samples. C: control rings; S: passively sensitized rings. P < 0.05 vs. S.Back to article page
