Abstract
This study was performed to investigate the effect of ultrasound irradiation on epidermal growth factor(EGF) expression in rat wound tissue. Skin wounds were created below 5mm to both sides of scapular inferior angle. The right wound was used experimental side and left was used control side. Ultrasound was irradiated pulse rate 20%, frequency IMI-Iz, intensity ⓒ.5W/cm2 for 5 minutes during 3days. After sonication during 3 days, rats were sacrified. The expression of epidermal growth factor evaluated immunohistochemistry on mouse anti-I. GF. In the control side, a little expression of EGF was observed at epidermis and dermis. In the experimental side, A strong immunostaining was seen at epidermis and dermis.
This study suggests that ultrasound irradiation is effective on EGF expression in wound tissue.
