The rabbits in the control group were not intervened. Then the heat therapy animals received heat therapy irradiation once every day for 15 days by in vitro HG-2000 high frequency heat therapy instrument (output power: 90%-95%, voltage: 220 V, controlled temperature: about 43℃, time: 10 minutes).
Normal saline(NS,500 ml) + Cisplatin(60 mg/m2) and 1 000 ml NS + 5-FU 500 mg/m2 for two weeks at 43-45℃ were infused rapidly into abdominal cavity in an hour in treatment group after ascites were drained by peritoneocentesis,then the patients were treated with hyperthermia by external high frequency thermo-therapeutic apparatus HG-2 000(60 min,twice a week).
Transurethral prostatic hyperthermia is a significant progress in uiology, following the extraneous shock -wave lithotrity. This paper introduces its principle,construction and applications.
The importance and difficulty of the temperature measurement and control in microwave hyperthermia instruments are discussed in combination with our scientific research work for many years.Plans of the temperature measurement and control,and the characteristics of the clinical application are compared.Finally the method of caculating the temperature distribution with few measurement signals and the advantages of using the adaptive generalized predictive control (GPC) are expounded.
