Expression of caspase 3 immunohistochemical staining (× 400). a A section obtained from the liver of a control rat shows caspase 3-immunolabeled hepatocytes were rarely present. b A section obtained from the liver of a rat treated with 500 mg/kg COC shows a decreased number of caspase 3-immunolabeled hepatocytes were observed around central veins, identified by brown staining. c Sections taken from the liver of a rat treated with curcumin followed by 500 mg/kg COC shows caspase 3-immunolabeled cells were slightly similar to the control group
