Clinical Observation


The Daunomycin, Cyclophosphamide, Cytarabine Hydrochloride and Vincristine Sulfale all are the drugs used in the therapy of leukemia. When the leukemia cell line, K562, were treated by themin vitro, a sharp decrease of intracellular free Ca2+ concentration could be found. The anti-cancer mechanisms of these drugs are inhibiting the DNA or RNA syntheses and interrupting the mitoses of tumor cells. Our experiment suggested that beside the above behaviors, these anti-cancer drugs can also suppress the function of tumor cells by means of decreasing their intracellular Ca2+ levels.
