Primary Study on the Effect of Hyperthermia Treated with Dextran Magnetic Fluid on Grafted H22 Tumor in Mice

Objective To study the effects of hyperthermia with dextran magnetic fluid on growth, vascular endothelial growth factor (VEGF) expression and apoptosis of grafted H22 tumor in mice. Methods Mice inoculated H22 tumor cells were divided into four groups randomly. The fourth group was injected into tumor with dextran magnetic fluid and treated with 55kHz, 20 kA/m alternating magnetic field for 10 min subsequently. The first, the second and the third group regarded as control groups, were injected with physiol...
