Oxygen free radicals have been shown to result from and mediate deleterious effects of ultraviolet radiation on the skin. The purpose of this study was to determine if topical DL-alpha-tocopherol (vitamin E) could reduce ultraviolet-induced damage to the epidermis. Twenty mice were treated with either ethanol or a 1:1 mixture of tocopherol and ethanol.(More)
During the past decade, many studies using platelet-rich plasma (PRP) or adipose-derived stem cells (ASCs) have been conducted in various medical fields, from cardiovascular research to applications for corneal diseases. Nonetheless, there are several limitations of practical applications of PRP and ASCs. Most reports of PRP are anecdotal and few include(More)
PURPOSE Studies regarding the effects of aesthetic outcomes after breast cancer surgery on quality of life (QoL) have yielded inconsistent results. This study analyzed the aesthetic outcomes and QoL of women who underwent breast conserving surgery (BCS) or total mastectomy with immediate reconstruction (TMIR) using objective and validated methods.

A positive cross-match in cadaveric liver transplantation is relatively acceptable, but its role in living donor liver transplantation (LDLT) is less well known. The aim of this study is to examine the significance of cytotoxic cross-match in adult-to-adult LDLT using small-for-size grafts. Forty-three adult-to-adult LDLTs were performed at Seoul National(More)
BACKGROUND Autologous fat grafting is a common procedure used in plastic surgery to correct soft tissue deficiency or depression deformity. However, absorption of grafted fat in the recipient area is unpredictable, and various methods for improving fat survival have been developed clinically. This study analyzed the changes and viability of injected fat in(More)
BACKGROUND Lower abdominal soft tissue transfer is the standard procedure for breast reconstruction. However, abdominal wall weakness and herniation commonly occur postoperatively at the donor site. To reduce the morbidities of the donor site, the superficial inferior epigastric artery (SIEA) flap was introduced, but inconsistent anatomy of the SIEA has(More)
Nipple-areolar complex (NAC) reconstruction is the final step in the long journey of breast reconstruction for mastectomy patients. Successful NAC reconstruction depends on the use of appropriate surgical techniques that are simple and reliable. To date, numerous techniques have been used for nipple reconstruction, including contralateral nipple sharing and(More)
Keloids and hypertrophic scars result from excessive collagen deposition, the cause of which is not yet known. Unlike hypertrophic scars, keloids frequently persist at the site of injury, often recur after excision and always overgrow the boundaries of the original wound. There have been many trials to control keloids, but most of them have been(More)
Wound contraction in humans has both positive and negative effects. It is beneficial to wound healing by narrowing the wound margins, but the formation of undesirable scar contracture brings cosmetic and even functional problems. The entire mechanism of wound healing and scar contracture is not clear yet, but it is at least considered that both the(More)
The applicability of the proximally based pedicled anterolateral thigh (ALT) flap has been well described with good results, but the use of a distally based ALT flap around the knee has not been fairly presented. The case of a male patient with a soft-tissue defect around the knee who underwent skin reconstruction based on an ipsilateral distally based ALT(More)
