A and B Negative and positive control groups show negative expression of caspase-3 in cardiomyocytes. C The acute treated group shows weak positive Caspase-3 expression in cardiomyocytes (arrows). D Chronic treated group reveals strong Caspase-3 expression in cardiomyocytes (arrows). E Chronic withdrawal group shows caspase-3-positive expression in cardiomyocytes (arrows)Back to article page
