Comparison of conventional and microwave hyperthermia. Leukocytes are exposed to conventional hyperthermia via water bath or microwave hyperthermia at 44 °C for 1 h. Leukocytes not exposed to hyperthermia are the negative control. A Cell death rates and B CIC rates are determined after 4 h of co-incubation
