<p><b>A</b>. Immonohistochemical localization of renin/prorenin in the aortas of normal, CKD and AST-120-treated CKD rats. <b>B</b>. Quantitative data of renin/prorenin-positive area in the aortas of normal (n = 9), CKD (n = 8) and AST-120-treated CKD rats (n = 8) (Mean±SE). ***p<0.001 vs normal, #p<0.05 vs CKD. <b>C</b>.
