Figure 1 Photominographs showing representative abnormalities of fibrin deposition and myocardial fibrosis in heart of a mouse with myocarditis in Experiment I (day 14). Interstitial fibrin deposition (A, arrows) and fibrosis (B, blue) in areas of myocardial necrosis in untreated group was more severe than in immunoglobulin-treated group (C, D). A, C = Immunoperoxidase stain for fibrin; B, D = Massons trichrome stain for fibrosis: A, B, C, D x120.
