| Outline of Final Research Achievements |
Our results in previous study indicated that magnetic fields (60 Hz, 50 mT) enhance the potency of drugs in bacterial cells and suggested that magnetic fields change the permeability of cell membrane and increase drug uptake. If magnetic fields enable us to enhance the potency of anticancer drug on target region only, the dosage can be reduced and thus side effects can be suppressed in clinical cancer chemotherapy. In present study, we made a magnetic fields exposure system for cultured human cells and measured the effect of magnetic fields on a potency of anticancer drug, cisplatin to human lung cancer cell line. The viabilities of A549 cells treated with cisplatin only and cisplatin under magnetic fields exposure (60 Hz, 50 mT for 24 hours) were measured by colony assay. The result suggested that magnetic fields (60 Hz, 50 mT for 24 hours) enhance the potency of cisplatin on human cancer cells.
