Fig. 2. Serum and urine cortisol are inversely correlated with eosinophil numbers in the peripheral blood of patients with adrenal Cushing syndrome. Correlations between (A) 24-hour urine free cortisol and the percentage of eosinophils and (B) serum cortisol and the percentage of eosinophils. (C) Dexamethasone inhibited eosinophil survival at a concentration-dependent manner in vitro. Data are representative of three independent experiments and are expressed as mean±SD. ^aP<0.05; ^bP<0.01 in comparison with the corresponding controls.
