摘要
作者们在冷冻治疗裸鼠移植瘤过程中测量了生物组织的介电常数。低温生物介电谱揭示:组织的相变过程是连续的,从0℃~-80℃。第三次冻融周期的相变温度明显高于首次冻融。作者相信,介电常数测量对于监测生物膜系统在冷冻过程中的动态变化是很有用的。
The authors measured the dielectric constant of biological tissues during cryosurgery on the transplanted tumors in nude mice. It was found that the dielectric spectrum showed the process of the tissues
phase change was continuous and it occurred from 0℃--80℃. The temperature of phase change in the third
freeze-thaw cycle was significantly higher than that in the first cycle, we believe that the dielectric constant measurment is very useful for dytect the dynamic change of biomembranous system in the course of cryosurgery
