The purpose of this study was to determine the effects of high voltage pulsed current (HVPC) stimulation on wound healing. Thirty-four Sprague-Dawley adult female rats were assigned to experimental and control groups. Each rats were anesthetized with pentotal sodium, and a 10 mm full-thickness incision was made on the back. From 24 hours after surgery, the rats of experimental groups were stimulated with HVPC, $140{\mu}s$, 120 pps, 30-40 V for 30 minutes, daily. The rats were sacrified 2 days, 4 days and 6 days after stimulation, respectively. The skin was removed, and processed for light microscopic examination. The length of incisional wounds were measured by microcaliper, and nucleolar organizer regions were counted under light microscope. For the histological observations the specimens were stained with Hematoxylin and Eosin, Masson Trichrome, Gomori Reticulum and Ag-NOR. There was a significant decrease in the length of incisional wound in experimental group compared with control group at 6 days HVPC stimuation (p<0.05). In experimental group, wound were significant difference (p<0.01) between the duration of post surgery. The mean numbers of nucleolar organizer regions per nucleus were significantly increased in the experimental group at 6 days HVPC stimulation (p<0.05), and were significantly difference (p<0.01) between the duration of post surgery in experimental group. Histological examination of the wound site suggested a more rapid of epithelialization and collagen formation between experimental groups compared with control groups. The result may indicated that the HVPC with $140{\mu}s$, 120 pps, 30-40 V for 30 minutes promoted surgical wound healing in the rat.
