Further studies of the rate of healing of human skin measured by the electrical wound potential of experimental abrasions

Abstract 1. 1. An experimental wound consisting of a circular abrasion 3 cm. in diameter on the arm showed a decline in positive electrical wound potential as healing progressed. This electrical sign of growth was slower in rate but similar to the decrease of potential previously described for smaller abrasions on the fingertips. 2. 2. Abrasions of the index finger heal more rapidly than those on the little finger. This electrical polarity of the human hand must be recognized when testing the effects of drugs on finger potentials. 3. 3. The rate of decline of wound potential is described for various dressings on experimental abrasions.
