Figure 3. Effects of C21 administration for 8 days on myocardial fibrosis in CsA-treated rats.

Figure 3

Panel 1: Representative photomicrographs of perivascular and interstitial fibrosis and inflammatory cell infiltration in left ventricle of control (a and d), CsA-treated (b and e) and CsA+C21-treated rats (c and f). Sirius red staining: interstitial fields, original magnification ×20; perivascular fields, original magnification ×40. Sirius red staining did not show changes in myocardial fibrosis, both at perivascular and interstitial area in CsA-treated rats (b and e) and CsA+C21-treated rats (c and f). Immunohistochemical staining of myocardial inflammatory cell infiltration showed a significant increase in interstitial monocyte/macrophage cells in CsA-treated rats (h) compared with control rats (g). C21 administration did not modify the increase of monocyte/macrophage infiltration in CsA-treated rats (i). Panel 2: Quantification of myocardial perivascular and interstitial fibrosis and monocyte/macrophage inflammatory cells in the different groups of rats. Data are means ± S.E.M. *P<0.01 compared the control group.
