Embodiment 1

[0035] Sixteen LS174T nude mice bearing human colon cancer were taken, and after the tumor volume was measured and calculated, they were randomly divided into two groups according to the tumor volume. The first group was the control group. Nude mice were injected with 0.1ml of water containing a certain amount of nano-magnetic powder, and the second group of nude mice were placed in the electromagnetic induction coil of the above-mentioned tumor magnetic hyperthermia treatment apparatus, and the frequency was 100KHz, and the field strength was 30KA / m. The temperature of the tumor was heated to 42-43° C. for 1 hour. After 10 days of treatment, the above-mentioned nude mice were sacrificed, the tumor was separated, and the weight of the tumor was weighed. The results showed that the tumor weight of the first group was 4.2±0.8g, the tumor weight of the second group was 1.3±0.3g, the tumor inhibition rate of the treatment group was 75%, and the P value was less than 0.01. At the s...

Embodiment 2

[0037] Sixteen LS174T nude mice bearing human colon cancer were taken, and after the tumor volume was measured and calculated, they were randomly divided into two groups according to the tumor volume. The first group was the control group. Nude mice were injected with 0.2ml of water containing a certain amount of nano-magnetic powder, and the second group of nude mice were placed in the electromagnetic induction coil of the above-mentioned tumor magnetic hyperthermia treatment apparatus, and the frequency was 200KHz, and the field strength was 20KA / m. The temperature of the tumor was heated to 42-43° C. for 1 hour. After 10 days of treatment, the above-mentioned nude mice were sacrificed, the tumor was separated, and the weight of the tumor was weighed. The results showed that the tumor weight of the first group was 2.77±0.75g, the tumor weight of the second group was 0.19±0.11g, the tumor inhibition rate of the treatment group was 93%, and the P value was less than 0.01.
