Figure 4. Curcumin administration (20 mg/kg bodyweight/day) decreases infiltration of IL-4 and IL-5 producing cells in the spleens and cervical lymph nodes (CLN) of mice in an ovalbumin (OVA)-induced allergic conjunctivitis model. The iNOS inhibitor, L-NMMA, administration also decreases infiltration of cells. Representative images of immunohistochemical staining for IL-4 and IL-5 in the spleens (A) and CLN (B) were demonstrated. Bar=20 μm.
