直流电疗法 ( directcurrenttherapy,DCT)用于恶性肿瘤 ,是在肿瘤内直接接入电极 ,通入直流电后 ,利用阴、阳极下发生的电化学、电生理反应 ,改变肿瘤的内环境 ,使肿瘤细胞丧失生存条件 ,产生多种病理变化 :细胞核固缩、细胞膜崩溃、线粒体消失、核蛋白凝固坏死 ,从而达到治疗 Direct current therapy (DCT) is used for malignant tumors. It is directly connected to the electrodes in the tumor. After the direct current is applied, the internal environment of the tumor is changed by the electrochemical and electrophysiological reactions occurring under the anions and the anodes, and the tumor cells are lost. Survival conditions, resulting in a variety of pathological changes: nuclear condensation, cell membrane collapse, disappearance of mitochondria, nuclear coagulation and necrosis, so as to achieve treatment
