在一定的低温和足够的时间条件下,当其作用于生物组织细胞时,可引起组织内部降温、凝固、结冰,使生物体内分子运动的速度减缓、停止,其结果使组织代谢率降代、抑制组织生长、甚至使组织细胞死亡而造成组织坏死。如对上述条件加以控制,则可利用冷冻对组织的作用而治疗疾病,使其达到治愈或缓解症状的目的。在这种启示下,冷冻技术被应用于临床医学。公元前3,500年,埃及人曾应用 Under a certain low temperature and enough time, when it acts on biological tissue cells, it can cause the inside of the tissue to cool down, solidify and freeze, so as to slow and stop the movement of molecules in the organism, and as a result, the metabolic rate of the tissue is reduced , Inhibit tissue growth, and even cause tissue cells to die and cause tissue necrosis. If the above conditions are controlled, you can use the role of frozen tissue on the treatment of disease, so that it can achieve the purpose of healing or relieve symptoms. With this revelation, cryogenic technology is used in clinical medicine. 3,500 BC, the Egyptians had applied
