RESUMEN
Adopting the cell model of multilayer spherical symmetry and the circuit analysis, the present paper gives the calculated results of the voltages on each of several parts of malignant Tonsillar B-cells and Jurkat T lymphocytes when the first-order Gaussian pulses at different central frequency apposed on them. The relationship between the central frequency and the transmembrane voltages of plasma membrane is also given. The optimum frequency causing electroporation in nuclear envelope is given as well. The paper discusses the reasons of electroporation in membrane and DNA degradation in nuclear. The work provides a reference for usage of transient bipolar electric pulses in cancer treatment.

Nuclear envelope voltages of T cells were analyzed with a lumped circuitry for cells in combination with frequency domain power density of Gaussian pulses and monocycle pulses. According to the differences in geometric and electric parameters between normal and malignant T cells, circuitry analysis was performed. Theoretical evaluations indicated that apoptosis of malignant T cells was of feasibility, which could be applied in cancer therapy. The evaluations were in accord with the published experimental findings.
