Figure 1 Histologic sections of kidney from 5/6 nephrectomized Wistar rat. Immunohistochemistry staining. Representative results are shown. (A) Glomerular and tubulointerstitial proliferating cell nuclear antigen (PCNA) immunostaining in rats 1week after 5/6 nephrectomy (NFX). Sections were counterstained with eosin (original magnification ×200), and (B) from a calcium citrate–treated animal (NFX-CIT). Sections were counterstained with eosin (original magnification ×200). (C) Immunohistochemical detection of α-smooth muscle actin in rats 10weeks after 5/6 nephrectomy (original magnification ×400), and (D) from a calcium citrate–treated animal (NFX-CIT) that shows positive staining only in arterioles (original magnification ×400). (E) Immunohistochemical detection of desmin in rats 10weeks after 5/6 nephrectomy (original magnification ×400), and (F) from a calcium citrate–treated animal (NFX-CIT) that shows positive staining only in arterioles (original magnification ×400). (G) Periodic-acid Schiff (PAS) staining in rats 20weeks after nephrectomy showing glomerulosclerosis, tubular atrophy, and interstitial infiltration (original magnification ×200), and (H) from a calcium citrate–treated animal (NFX-CIT) (original magnification ×200).
