A: Rh-123 fluorescence intensity curve in H22/ADM cells after exposure to chemotherapeutic agents at 24 h . B: Rh-123 fluorescence intensity curve in H22/ADM cells after exposure to chemotherapy agents at 48 h. C: Rh-123 fluorescence intensity curve in H22/ADM cells after exposure to chemotherapy agents at 72 h.Back to article page
