Basic Study

In vitro and in vivo experiments on temperature rise with microwave

To confirm the temperature raising effect of microwave irradiation, microwaves were irradiated in vivo and in vitro, and the subsequent temperature rise was examined. In experiment (A), six culture vessels containing physiologic saline were irradiated for 9 seconds, 7 seconds, 5 seconds and  3 seconds three times each, and the effective temperature of 42°C was reached.  In experiment (B), BALB/C(albino) mice were irradiated with microwaves for 5 seconds, 4 seconds and 3 seconds three times each, and the temperatures in the esophagus and rectum were measured. As a result, the effective temperature of 42°C was reached through 3 sets of 4-second irradiation.  The results of both the in vitro and in vivo experiments confirm that microwave irradiation for the appropriate time can raise the internal temperature up to the effective temperature. The overview of the experiment process and results are as shown below (Results from experiments conducted by Dr. Motomura Tadashi, Associate Professor, Baylor College of Medicine, United States).
