Eosinophils accumulate in renal interstitium after unilateral ureteral obstruction (UUO). A: representative kidney sections immunostained for major basic protein (MBP), an eosinophil marker, from wild-type (WT) mice 7 days after sham surgery or UUO depicting medulla and corticomedullary junction regions. MBP-positive cells within the corticomedullary region tended to accumulate around vessels, whereas medulla MBP-positive cells were diffusely present. B: quantification of the no. of MBP-positive cells per high-power field in WT mice after sham surgery or UUO (n = 3 in both groups, ***P < 0.005). Scale bar = 50 μm for ×200 images and 20 μm for ×400 images.
