温热疗法是治疗恶性肿瘤的最新辅助疗法,对于培养细胞的温热感受性研究证明,恶性细胞和正常细胞对温热的感受性具有明显差异,活体研究亦证明恶性组织的温热感受性比正常组织高,而且在乏氧情况下,可以增强对肿瘤的抗癌作用。作者对34只家兔VX_2肿瘤作了实验性研究,结果看到,当加温到43℃时,即刻及3小时后血管造影像显示动脉变细,中断。24小时以后缓慢恢复。组织学上加温43℃后即刻见到肿瘤边缘及周围非癌部血管扩张、郁血及破裂出血。加温3小时后,肿瘤内微血管广泛血栓形成,血管周围的肿瘤细胞变性。加温到24小时后,肿瘤广泛坏死。当加到41℃后,即
Hyperthermia is the latest adjunctive therapy for the treatment of malignant tumors. Studies of warm sensibility of cultured cells have demonstrated that malignant cells and normal cells have apparently different susceptibility to warmth, and living studies have also proved that the warm tissue sensitivity of malignant tissues is higher than that of normal tissues. , And in the absence of oxygen, can enhance the anti-cancer effect of the tumor. The authors conducted an experimental study of 34 VX_2 tumors in rabbits. The results showed that when heated to 43°C, arterial thinning and disruption occurred immediately after 3 hours. Slow recovery after 24 hours. Histologically heated 43 °C immediately after the tumor edge and surrounding non-cancer vasodilation, blood stasis and bleeding. After warming for 3 hours, the microvessels in the tumor were extensively thrombotic and the tumor cells surrounding the blood vessels were degenerated. After warming up to 24 hours, the tumor was extensively necrotic. When added to 41°C,
