Representative photomicrographs of immunocytochemical staining for monocyte/macrophage infiltration (ED-1-positive cells) in the kidney cortex of stroke-prone spontaneously hypertensive rats (SHRSPs). A: mild infiltration in sham-operated (Sham) SHRSP (arrows). B and C: accumulation of inflammatory cells was prevented in the adrenalectomy (ADX) and ADX + angiotensin II (ANG II) groups when aldosterone (Aldo) was absent. D: when Aldo was given back (ADX+Aldo), a substantial increase in ED-1-positive cells was observed (arrows).
