[The effect of extracellular perfusion on dielectric spectroscopy of skeletal muscle cells].
The dielectric spectroscopy of the skeletal muscle cells is approached by extracellular perfusion, using curve fitting and numerical calculation with nonlinear Cole-Cole equation, and the dielectric parameter of skeletal muscle cells is compared after perfusion, The results show: (1) the permittivy at low frequency (epsilon1) and the conductivity at hight frequency (kappa(h)) reduces in keeping with extracellular perfusate; (2) the effect of extracellular perfusion on the characteristic frequency (f(c1),f(c2)) is small; (3) the extracellular perfusion mostly influences the peaks of deltaepsilon" and tgdelta for the skeletal muscle cells.
