The degree of drug-resistence was detected by MTTmethod; the concentration of ADM in cells BIU-87 and BIU-87/ADM was detected after the cells were treated by carvedilol and ADM.
Results:
Pretreatment by carvedilol increased the concentration of ADM in BIU-87/ADM cells, ,and the concentration was much higher than that in those cells treated by ADM only.
