Abstract

A rapid increase of skin temperature after discontinuation of local microwave (MW) exposure of the heart and thyroid indicates a vasomotor response in the exposed and adjacent zones. The infrared radiation (IR) of the particular parts of skin surface before and after local MW exposures (460 MHz, current density 10, 120 and 230 mW/cm2) of the rabbit heart and thyroid regions was registered by IR thermograph. The investigations were performed on un-narcotized, narcotized (nembutal 40 mg/kg) animals, on rabbits with anaesthetized skin receptors (lidocaine 100 mg) and on carcasses. The changes observed depended on the exposure site, functional status of the rabbits and MW current density. The energy-depending reactions are attributed to direct myocardial reactions and extracardiac vegetative responses in the cardiac and thyroid exposures, respectively.

摘要

停止对心脏和甲状腺进行局部微波（MW）照射后，皮肤温度迅速升高，这表明在暴露区域和相邻区域存在血管舒缩反应。通过红外热像仪记录了兔心脏和甲状腺区域在局部MW照射（460 MHz，电流密度分别为10、120和230 mW/cm²）前后皮肤表面特定部位的红外辐射（IR）。研究在未麻醉、麻醉（戊巴比妥40 mg/kg）的动物、皮肤感受器麻醉（利多卡因100 mg）的兔以及尸体上进行。观察到的变化取决于暴露部位、兔的功能状态和MW电流密度。能量依赖性反应分别归因于心脏照射时的直接心肌反应和甲状腺照射时的心外自主反应。
