In order to study a new tumor treatment method using steep pulsed magnetic fields (SPMF), this paper developed a SPMF generator by means of the integration of pulsed power technology and modern power electronics technology. After a brief introduction of basic principle of SPMF generator, steep pulse formation circuit and Helmholtz coils, two main parts of SPMF generator, were discussed in detail,...
Mitochondrial plays an important role in apoptosis, and measuring the change of mitochondrial transmembrane potential (DeltaPsim) is a useful method for apoptosis. Exposing human liver cancer cell SMMC-7721 dyed with Rhodamine 123 to steep pulsed electric fields (SPEF), this paper observed the real-time change of DeltaPsim using laser scanning confocal microscope (LSCM) to study the apoptosis effect...
A more proper and realistic multilayer dielectric model of spherical biological cell, in which nuclear was taken into consideration, was proposed based on the classic dielectric model in this paper. The general analytical method was also deduced and analyzed in detail in calculating the time courses of transmembrane potentials of both inner and outer membranes induced by constant and time-varying...
Exposing cancer cell to steep pulsed electric field (SPEF) with appropriate dosage, the cell may die due to irreversible electrical breakdown (IREB). 48 BALB/c mice inoculated with U/sub 14/ cervical cancer cell were treated with SPEF to study the lethal and inhibitory effects of SPEF on them. They were randomly divided into test group (26) and control group (22), and then four experiments were carried...
