(a) Sham group: normal control heart showing normal cardiac muscle fibers. (b) WSLEt + Sham group: WSLEt-treated (100 mg/kg) heart showing normal muscle fibers without any pathological changes. (c) WSLEt + ISO group: WSLEt-treated (100 mg/kg) + ISO-treated (85 mg/kg) heart showing no edematous intramuscular space and fewer inflammatory cells (black arrows). (d) ISO group: ISO-treated (85 mg/kg) heart showing cardiac muscle fibers with muscle separation (green arrows), edematous intramuscular space (red arrows), and inflammatory cells (black arrows).
