Nocturnal asthma is associated with circadian rhythms. Although glucocorticoids have contributed to therapeutic success, the underlying mechanism has not been studied thoroughly in asthma. Here, we report that cortisol, a member of glucocorticoids, ameliorate guinea pig tracheal spasm via a nongenomic effect. We set a concentration gradient of cortisol to mimic the functional circadian fluctuation. When administrated over a threshold (150 ng/ml), cortisol could synergize with the spasmolytic… CONTINUE READING
