(a) Group I: H & E stained myocardial tissue section from normal control heart showing normal cardiac muscle fibers. (b) Group II: pretreatment with MP (100 mg/kg) showing normal muscle fibers without any pathological changes. (c) Group III: ISO (85 mg/kg) treated heart showing cardiac muscle fibers with muscle separation (black arrows), edematous intramuscular space (red arrows), cellular necrosis (blue arrows), and infiltration of inflammatory cells (green arrows). (d) MP (100 mg/kg) + ISO (85 mg/kg) treated heart showing lowered inflammatory cells (green arrows) and reduced muscle fibrous separation with edematous intramuscular space.
