目的研究在使用微波照射胸部过程中,照射靶点与周围组织以及全身温度的变化情况,并比较和改良加热方式.方法采用不同体外微波照射方式,对健康成年新西兰兔胸部不同部位进行照射,分别测量照射区域表皮、皮下、深部及邻近组织的温度和肛温.按重复测量数据的两因素多水平设计实验并分为a、b、c、d组.结果 d组兔背侧肺表面温度升高速度与b1组相似(F=0.02,P>0.05);腹侧肺表面温度升高较慢,10 min后该部位所测温度平均值低于b1组(F=10.04,P<0.01);而肛温升高较快,10 min后该部位所测温度平均值高于b1组(F=7.04,P<0.01)结论多发射源阵列照射方式可安全地获得满意照射深度及合适治疗温度,在良好控制下微波照射是理想热疗手段.

Objective To clarify the temperature curve of the irradiation target area,its adjacent tissue and the whole body during extracorpereal microwave irradiation, then to compare and optimize different irradiation models. Methods Different parts of the chest of adult New Zealand white rabbit were irradiated using different extracorporeal microwave irradiation models. The temperature of the irradiated skin, the subcutaneous and deep parts, the adjacent tissues and the anus was measured. The experiment was bi-factor and multi-level designed according to the repeatedly measured data and the rabbits was divided into group a,b,c and d. Results The increase rate of the surface temperature in the dorsal lung was similar between group d and group b1(F=10.04,P<0.01). However,the increase rate of the surface temperature in the ventral lung of group d was lower, and the mean temperature of this site measured 10 minutes later was also lower than group b1(F=10.04,P<0.01). The increase rate of the rectal temperature of group d was higher,and the mean rectal temperature tested 10 minutes later was also higher than group b1(F=7.04,P<0.01). Conclusions Multi-array irradiation could achieve satisfactory irradiation depth and appropriate therapeutic temperature. Well controlled extracorporeal microwave irradiation under is an ideal thermotherapy method.
