Figure 5From: Oral treatment with Euterpe oleracea Mart. (açaí) extract improves cardiac dysfunction and exercise intolerance in rats subjected to myocardial infarction Cardiac fibrosis. Collagen volume analysis of the left ventricle from Sham, MI and MI rats treated with açaí extract (100 mg/kg) during 4 weeks. (A) Picrosirius red staining of left ventricle under light microscopy (magnification 20×), showing collagen fibers in red color. (B) Collagen volume fraction of left ventricle (%). Values are mean ± S.E.M. *P < 0.05 vs. Sham. # P < 0.05 vs. MI.Back to article page
