Abstract:
This study sought to assess the inhibitory effects of the adriamycin magnetic albumin microspheres(ADM-MAMs) on Walker-256 mal ignant tumor cells in vitro induced by the permanent magnetic fields.T he cultured Walker-256 cells were divided into three groups:the group o f ADM-MAMs combined with magnetic fields, the group of AMD-MAMs without magnetic fields, and ADM group.The growth states of the cells were obse rved and photographed under the inverted microscope.The inhibitory rates(IR) were assayed by the modified MTT colorimetric method.The resu lts showed that the IR of the ADM-MAMs group were similar to those of the ADM group (P>0.05),but the group of ADM-MAMs combined with magnetic field s had obviously higher IR and significent changes of the cells′ shapes.These findings indicate that the anticancer effect of ADM-MAMs on malignant tumor cells is similar to that of ADM,and such effect can be increased by the combined use of ADM-MAMs and external magnetic fields.
