我院痔科1974年4月19日～1975年9月底,冷冻治疗痔疮297例,取得一定疗效,现将近期疗效分析如下: 一、冷冻治疗的机制极度冷冻对正常细胞和肿瘤细胞都足以造成不可逆性损害,其温度至少要低于-20℃以下,并持续一定时间,才能使组织细胞冰晶化而形成冰球。同时迅速而反复的冷冻和复温融解交互转换,逐步造成细胞的破裂,以致细胞坏死。冷冻在生化和细胞形态学上所引起的变化和破坏,主要表现在细胞内脂蛋白成份的变性
Hemorrhoids in our hospital April 19, 1974 to the end of September 1975, 297 cases of hemorrhoids cryotherapy, and achieved a certain effect, the recent curative effect is as follows: First, the mechanism of cryotherapy Extreme freezing of normal cells and tumor cells are sufficient to cause Irreversible damage, the temperature should be below at least below -20 ℃, and lasted a certain period of time, in order to make the cells ice crystal form ice hockey. At the same time rapid and repeated freezing and rewarming melt interactive conversion, and gradually lead to cell rupture, resulting in cell necrosis. Changes in freezing and biochemistry and cell morphology caused by the destruction and destruction, mainly in the cell lipoprotein components of the degeneration
