Staining intensity: 0, negative, no reactivity; 1, trace, faint or pale brown staining with less membrane reactivity; 2, weak, light brown staining with incomplete membrane reactivity; 3, moderate, shaded of brown staining of intermediate darkness with usually almost complete membrane reactivity; 4, strong, dark brown to black staining with a usually complete membrane pattern, producing a thick outline of the cell [17,18,19].

Aldo, aldosterone; Ep., eplerenone (n=6/group); GL, glomerulus; PCT, proximal convoluted tubule; DCT, distal convoluted tubule; CCD, cortical collecting duct; Pcap, peritubular capillary; TALH, thick ascending limb of the loop of Henle; MCD, medullary collecting duct; VR, vasa recta; tLH, thin limb of the loop of Henle.
