[Passive electrical tissue parameters of normal and pathologically altered cervical epithelium]

Normal and pathologically changed tissues can be distinguished on the basis of passive electric measurements, if the concentrations of the membranes, the resistance of the membranes, the membrane capacity, or the conductivity in and outside of the cells are different for both tissues. The electrical parameters are immediately measurable without anesthesia under in vivo conditions by change of electrical pulses. 2043 measurements on 300 patients were carried out. A suitable combination of electrical parameters of the tissues revealed that there is a difference of 64.5 +/- 0.5% between normal and pathologically changed epithelium (cancer).
