A wound model for decubitus and leg ulcers consisting of human dermal fibroblasts in type I collagen dermal "equivalent" matrix (DEM) was exposed in vitro to electric fields similar to postulated endogenous fields in wounds. After an 8-10 day maturation period, conductivity of DEM samples was determ

β¦ Synopsis
In a dermal wound model, consisting of human skin fibroblasts in collagen matrix, continuous sinusoidal electrical current stimulation elicited a maximum increase of [ 3 H]thymidine relative to control at 41 mV/m amplitude, 10 Hz. In this paper we elaborate cell cycle kinetics, using the same parameters. Labeling occurred over 4-h intervals beginning at 12 to 20 h after onset of electric exposure. The results suggest a significant increase in [ 3 H]thymidine incorporation over an 8-h period extending from 16 -24 hours after stimulus initiation.

This work was undertaken to compare the behavior of Friend erythroleukemia cells in a solenoid, where the magnetic field was 70 mT at 50 Hz (plus 45 mT DC of Earth) with that of the same cells in a magnetically shielded room, where the magnetic field was attenuated to 20 nT DC and 2.5 pT AC. The con
