Cytotoxic effect of pre and co-administration of pCA and Dox on H9c2 cells. Values are expressed as ±SD of three individual experiments. Typical morphological changes of H9c2 cells treated pCA, dox and pre/co-administration of pCA after 72 h of treatment. F indicates the % cell viability of control, Dox and pCA treated cells, Dox + pCA indicates co administration, pCA + Dox indicates pre treatment. *Significant compared to control (p < 0.05), **significant compared to Dox (p < 0.05). The picture is the representation of three separate experiments.
