Özet
The possible beneficial effects of a specially pulsed electric field (PEF) on wound healing were investigated in this study. We made a pair of triangular, full-thickness, dorsal incisions in the skin of 32 healthy male mice (one control group and three exposure groups). The treatment groups were kept between parallel plates in a partially insulated exposed environment. Group I was exposed to an electric field intensity of 10 kV/m, group II was exposed to 1.9 kV/m, and group III was exposed to 0.9 kV/m. PEFs were applied to the subjects for 20-22 h and 8 consecutive days. We determined the differences in wound recovery between the groups based on the following parameters: collagen fiber density, inflammatory infiltration density, capillary proliferation, and existence of exudates. We found that a 0.9 kV/m-1.9 kV/m chopped direct current (DC) electric field with a 30 A mu s repetition time favorably affected collagen synthesis and wound recovery. Despite the intensity of 0.9-1.9 kV/m, PEF accelerated healing, but 10 kV/m decelerated this recovery process.
