Xuefei Liu, Xinglei Zhu, Aiying Wang, Hui Fan, Haitao Yuan  International Journal of Cardiology  Volume 137, Issue 3, Pages (November 2009) DOI: /j.ijcard Copyright © 2009 Elsevier Ireland Ltd Terms and Conditions

2 Fig. 1 Representative M-mode echocardiograms of rats from untreated group and high-dose valsartan-treated group. N represents group N; H represents group H. High-dose valsartan treatment significantly prevented the progression of left ventricular remodeling and heart failure.

3 Fig. 2 Representative pathological images of hematoxylin–eosin staining of hearts (×200), A–D represent group C, group N, group L and group H separately. The infiltration of inflammatory cells was reduced significantly by valsartan treatment.

4 Fig. 3 Representative pathological images of Masson's trichrome staining of hearts (×200), A–D represent group C, group N, group L and group H separately. The myocardial fibrosis was reduced by valsartan treatment. International Journal of Cardiology  , DOI: ( /j.ijcard ) Copyright © 2009 Elsevier Ireland Ltd Terms and Conditions

5 Fig. 4 Results of T lymphocyte proliferation assay of rats from the four groups. Valsartan suppressed lymphocyte proliferation in response to myosin stimulation significantly. *P<0.05 vs. group N; #P<0.05 vs. group L.

6 Fig. 5 Levels of cytokines of Th1 (IFN-γ and IL-2) and Th2 (IL-4 and IL-10) evaluated by ELISA. Th1 cytokines were significantly down-regulated, while Th2 cytokines were detected to undergo up-regulation by valsartan administration. *P<0.05 vs. group N; #P<0.05 vs. group L.
