The effects of RU24858, mometasone and dexamethasone on spontaneous eosinophil apoptosis. The effects of RU24858 (0.01 μM, 0.1 μM, 1 μM), mometasone (0.01 μM, 1 μM) and dexamethasone (0.1 μM, 1 μM) on spontaneous eosinophil survival. Values are the mean ± S.E.M., n = 6. Results are expressed as percentage of apoptotic cells. * Indicates P < 0.05, ** P < 0.01 and *** P < 0.001 as compared with the respective control in the absence of glucocorticoids.
