Time evolution of temperature distribution in the human abdominal cross section is investigated on the basis of numerical analysis of governing heat conduction equation, emphasizing the effect of the surrounding cooling water. The human abdomen is simplified by a model of cylindrical muscle medium whose cross sectional shape is a rectangle sandwiched between two semicircles. Enhancement of metabolism, i. e., the increase of blood perfusion caused by the temperature rise, is taken into account as a function of the maximum temperature in the abdominal region. It is shown, for example, that the permeation of cooling effect is rather slow (several centimeters after one hour at most), but the effect of water cooling is very pronounced, and that the use of such a coolant will be indispensable to heating a deep-situated tumor region.
