Map and Dex (0.4%; w/v) eye drops do not cause any apparent increase in the number of positive apoptotic eosinophils detected by TUNEL procedure in tarsal conjunctival sections prepared from guinea pigs sacrificed 6 hours after Map and Dex treatment (8 hours after OVA challenge).

Notes: Contrary to apoptotic eosinophils, non-apoptotic eosinophils infiltrating the conjunctiva, evidenced by chromotrope-2R, were increased by OVA challenge and reduced by Map and Dex. Ctrls were not treated with OVA. Representative micrographs, in which TUNEL-positive cells appear as distinct, rounded, bright green nuclei and chromotrope-2R-positive cells appear as red spots, are shown. Each group comprised five guinea pigs, and both eyes were evaluated (n=10).

Abbreviations: Ctrl, control; Dex, dexamethasone; Map, mapracorat; OVA, ovalbumin; TUNEL, terminal deoxynucleotidyl transferase dUTP nick end labeling.
