Several large foci of cellular infiltrations (arrow) in the inflammatory region are shown (grade 3). (c) Representative histopathology in a carvedilol group. Several small foci of cellular infiltrations in the inflammatory region (arrow) are shown (grade 2). (d) Representative Masson’s trichrome stained heart in a normal group. (e) Representative Masson’s trichrome stained heart in a myocarditis group. (f) Representative Masson’s trichrome stained heart in a carvedilol group.
