冷冻治疗是利用各种不同的零下低温,使组织和细胞迅速降温,对局部病理性细胞或组织发生所需的不同程度的破坏,同时可激发机体免疫能力,从而达到治疗疾病和破坏肿瘤的一项技术。冷冻使细胞和组织产生以下改变:①由于细胞中水分的丢失而致脱水和电介质浓缩;②细胞内外结冰,伴随细胞膜的破坏而产生冰冻的结晶;③细胞膜内液体蛋白分子的变性;④发生冷休克;⑤血管瘀血,微循环停止,局部毛细血管阻塞,邻近较大血管血流停滞。治 Cryotherapy is the use of a variety of sub-zero temperature, the rapid cooling of tissues and cells, the local pathological cells or tissues required to varying degrees of damage, and can stimulate the body’s immune capacity, so as to achieve the treatment of disease and destruction of the tumor Technology. Frozen cells and tissues to make the following changes: ① due to the loss of water in the cells caused by dehydration and dielectric concentration; ② inside and outside the cell freezing, with the destruction of the cell membrane to produce frozen crystals; ③ cell membrane protein molecules of liquid degeneration; ④ occurred Cold shock; ⑤ blood stasis, microcirculation stopped, local capillary obstruction, blood vessels near the larger blood stagnation. rule
