Photomicrographs of left ventricular tissue of adult male rats stained by Masson’s trichrome stain (× 400). (A) The control group is showing no collagen of myocardium. (B and C); MI/R injury group showing large patchy areas of collagen fibers deposition in the interstitium (*) and between distorted cardiac muscle fibers (↑). (D–F); TNA 50, 100, 200mg Treated groups respectively, showing scattered collagen fibers deposition inbetween cardiac muscle fibers (↑). (G–I); PTX 20, 30, 40mg Treated groups respectively, showing few scanty collagen fibers (↑). (J–L); CY3 5, 10, 15mg Treated groups respectively, showing no obvious collagen deposition as normal.
