Abstract: A Tateishi Denki-made, 13.56 MHz, induction heater, Model HEH-500C was used to study heating characteristics, and histologic retrieval of heated organs, and to clarify the following matters. Heating characteristics : Two mini-pigs, weighing 43 kg and 30 kg, respectively, were subjected to five patterns of heating. The results of heating experiment are summarized as follows. 1) Without the large -sized cooling bolus, both abdomen and groin were easily heated to the temperatures higher than 43°C.2) With the large-sized cooling bolus, the deeper regions of both abdomen and groin were difficult to be heated to the temperatures higher than 42°C. 3) The large-sized cooling bolus prevents heating of body surface and panniculus adiposus, but deteriorates heating of the deeper regions. The large-sized cooling bolus should be used after weighing the merits and demerits, and setting the conditions carefully. 4) The small intestines and stomach are easily heated to higher temperatures, but the liver and pancreas are difficult to be effectively heated. Histologic changes : The histologic retrieval was made of the organs of the two mini-pigs subjected to the heating experiment. The examined organs included the stomach, small intestines, dorsal muscles, adipose tissues, liver, and spleen. Findings after heating showed without exceptions the three items : edema and hyperemia, bleeding, and necrosis. The relationship between the temperatures and the histologic changes were clarified in each organ studied. The histologic changes were most remarkable in the small intestines, then fairly noticeable in the stomach, muscles and adipose tissues, and least remarkable in the liver and spleen. The heating characteristics of 13.56 MHz induction heater, Model HEH-500C and the results of histologic retrieval present the important, basic data for consideration of indications and features of clinical application.
