Methods］ MTT assay was employed to test the lethal concentration 50 (IC50) of sensitive germline (SK-OV-3) and ovarian cancer cell subline induced by ADR (SK-OV-3/adr) treated by 4 drugs, resistance index and reverse multiple were calculated. The changes of drug content were observed by fluorescence microscope, the intracellular accumulation of ADR was evaluated by fluorospectrophotometry, the changes of mdr 1/P-gp resistance were observed respectively by RT-PCR and Western blot.
