Fig. 4.
Protein expressions of cyclooxygenase-2 (COX-2) and inducible nitric oxide synthase (iNOS) in renal parenchyma. Mice in groups B (allergic group) and C (null treatment group) expressed significantly higher COX-2 levels in renal tissues than mice in group A (control group), but mice in group D (anti-IL-33 group) expressed significantly lower COX-2 levels than mice in groups B and C (P<0.05). Group iNOS protein levels showed no significant difference, although levels tended to be lower in group D (P>0.05). Kruskal-Wallis and Mann-Whitney U-test. CON, control; AR, allergic rhinitis; IL, interleukin.
