冷冻治疗肿瘤之机理虽未完全搞清,但有两点是被公认的:冷冻能杀死瘤细胞;冷冻可刺激机体免疫力。实验研究表明在-5～-50℃范围内,温度越低、降温越快、复温越慢和浆——融次数越多,则对细胞杀伤力越大。实验研究也发现组织的冷冻损伤可作为抗原刺激物激发机体形成抗体,而这种“冷冻免疫” Although the mechanism of cryotherapy for cancer is not fully understood, there are two points that are recognized: freezing can kill tumor cells; freezing can stimulate immunity. Experimental studies have shown that in the range of -5 to -50°C, the lower the temperature, the faster the temperature drop, the slower the rewarming, and the more pulp-melting times, the greater the lethality to cells. Experimental studies have also found that frozen tissue damage can be used as an antigen stimulator to stimulate the body to form antibodies, and this “freezing immunity”
