  • The wound healing process can be categorized as follows : inflammation, fibroplasia, neovascularization, collagen deposition, epithelialization, and wound contraction. During the healing process, various growth factors are secreted to accelerate wound healing. Previous studies have demonstrated that endogenous growth factors, such as vascular endothelial growth factor(VEGF) are the important regulatory polypeptides for coordinating the healing process. They are released from macrophages, fibroblasts, and keratinocytes at the site of injury and participate in the regulation of reepithelization, granulation tissue formation, collagen synthesis and neovascularization. Onchung-Um has been used clinically to treat various skin diseases. In addition, Onchung-Um has been also used for congestive inflammations. In the present study, we evaluated the effects of Onchung-Um on wound healing process and wound size reduction in rats. Full-thickness skin wounds ($15mm\;{\times}\;15mm$) were created on the back of rats. Rats were then divided into 2 groups : The Onchung-Um treated group that was orally administered with a dose of 193.9mg/100g of Onchung-Um extract per day for 15 days and Control group without Onchung-Um administration. Moreover, the histological changes and VEGF immunoexpressions of two groups were estimated. In results, wound closures were significantly accelerated by oral administration of Onchung-Um extract. Furthermore, in Onchung-Um treated group, there were significant increases in fibroblast migration, epithelialization compared with the Control group. VEGF expressions were also increased in Onchung-Um treated group. This study has therefore demonstrated the Onchung-Um can significantly improve the quality of wound healing and scar formation and the oral administration of Onchung-Um extract may increase early tissue angiogenesis in the incisional wound of an experimental animal model.

  • Synovial fistula of the ankle joint is an uncommon complication from an ankle sprain. This may likely result in an unhealed wound around the ankle joint due to continuous leakage of joint fluid. However, in the event of an open wound on the lower leg, and not on the joint, it may be difficult to consider synovial fistula as a cause of the open wound. We experienced an interesting case with an unhealed open wound on the lower leg due to a synovial fistula of the ankle joint following an ankle sprain. We obtained good results after a treatment using a self-produced suction drainage device on the unhealed open wound.

  • Ketoprofen has been used as nonsteroidal anti-inflammatory (NSAI) agent for analgesia in surgical patients and increasing numbers of surgical patients are chronically take some forms of NSAI drugs. The purpose of this study was to investigate the therapeutic effects of ketoprofen on the healing of a closed linear surgical wound and on the contraction of an opened surgical wound in rats. The experimental groups were divided into two groups and ten rats were allocated in each group. In ketoprofen-treated group, the rats were given 2.5 mg/mg/day of ketoprofen by s.c. for ten days. In control group, the rats were given 1ml of benzyl alcohol and distilled water by s.c. for ten days. After time period, all rats were sacrificed, and the breaking strength and the collagen concentrations, at the wound site, were measured. In ketoprofen-treated group, the mean breaking strength and the mean collagen concentration were significantly decreased when compared with those of controls. The ketoprofen-treated group had shown a mean rate of wound contraction less than that of the control, although not statistically significant. These results suggested that ketoprofen impaired wound healing.

  • The oriental ore minerals, which mainly consisted of talc, actinolite, sericite, and halloysite were developed, and then used to examine the healing effect on the skin wound in rats. Full-thickness square wounds were formed on the backs of rats after the hairs on the dorsal surface were shaved. The ore minerals were applied to examine the healing effect from day 0 to 15 after wounding. Notable wound healings in terms of congestion around the wound, wound contraction and epithelialization were found in ore mineral-treated groups. Moreover, microscopic results revealed the formation of epithelial layer, hair follicles and progressive angiogenesis in ore mineral-treated groups, while complete epithelial layer could not be found in the control. These results suggest that ore minerals from Korean indigenous ores may have wound healing effect on the skin injury in rats.

  • Gorwth factors such as TGF-beta, PDGF and FGF are thought to play important roles in wound healing. However, thier biological activity and signal transduction during wound repair remain poorly understood. Growth factors are often ligands for receptor tyrosine kinase and receptor serine/threonine kinases. With recent advances in signal transduction by receptor kinases, we are beginning to understand the underlying mechanism of how growth factors may regulate cutaneous wound repair. In this paper, we will describe the pharmacological effects of growth factors on wound healing, and dscuss the potential underlying signaing mechanisms. thus, we hope to provide the basis for designing more specific therapeutics for wound healing in the near future.

  • In the field of tissue engineering and reconstruction, the development of efficient biomaterial is in high demand to achieve uncomplicated wound healing. Chronic wounds and excessive scarring are the major complications of tissue repair and, as this inadequate healing continues to increase, novel therapies and treatments for dysfunctional skin repair and reconstruction are important. This paper reviews the various aspects of the complications related to wound healing and focuses on chitosan because of its unique function in accelerating wound healing. The proliferation of keratinocytes is essential for wound closure, and adipose-derived stem cells play a significant role in wound healing. Thus, chitosan in combination with keratinocytes and adipose-derived stem cells may act as a vehicle for delivering cells, which would increase the proliferation of keratinocytes and help complete recovery from injuries.

  • The effects of ethanol extract of Ruta graveolens on ulceration induced by ethanol and wound healing properties were investigated in mice. Oral administration of the extract reduced the incidence of ulcer, ulcer index and ulcer length produced by ethanol. The gastroprotective effects of R. graveolens were observed in a dose-dependent manner. However, this activity was statistically less potent than the anti-ulcer drug, omeprazole. When the extract applied on the wound, it promoted wound healing in mice. The wound contraction was faster in these mice when compared to untreated wounds. Based on these present findings, R. graveolens possesses anti-ulcer activity and promotes incision wound healing in mice.

  • Treatment towards wound healing, a complex and dynamic process, has been given a great deal of efforts in the last few decades. Focus has been imposed on developing wound dressings that meet the requirements for proper wound healing. In this study, hydrogel made from blends of poly (vinyl alcohol) and ${\beta}$-1,6-branched-${\beta}$-1,3-glucan (beta-glucan) were synthesized by modified solvent casting method for wound dressing application. Optimization of hydrogel composition and analysis of wound dressing parameters such as stability and fluid uptake capacity (in the presence of water, saline and different pH solutions) has been studied. The result indicated that the PVA/beta-glucan hydrogel hold its structural integrity even at alkaline pH (pH~9) and upholds fluids four times of its original weight. Thus, the developed hydrogel is expected to be a promising candidate as wound dressing.

  • The purpose of the present study was to investigate the effect of polyphosphate on healing of skin wound in rabbits. Four skin wounds of 8mm in diameter were induced bilaterally(4 wounds/rabbit) on the dorsolateral aspect of the trunk of 15 male New Zealand white rabbits. Ten percent polyphosphate(poly P) type 25, 10% poly P type 35, 10% poly P type 25+10% poly P type 35 and 0.85% sterile saline solution were applied on the wound area and examined grossly and histopathologically. The rate of wound contraction and histopathological changes after poly P application on the skin wound were investigated. In gross findings, the wound contraction rates of 10% poly P 25 group were significantly decreased from day 2 to day 7 after operation than those of 0.85% sterile saline solution treated group (p < 0.01). Although the hemorrhage and inflammation were observed on days 3, 6 and 9 after operation in all groups, but in 10% poly P 25 was gradually decreased. Revascularization and reepithelialization were seen 3, 6 and 9 days after operation in all groups, especially in 10% poly P 25 was formed completely on 9 days. Fibroplasia were seen 3. 6 and 9 days after operation in all groups, especially in 10% poly P 25 was compact than other groups on 9 days. The results suggested that polyphosphate, especially 10% poly P 25 would be effective on healing of skin wound in rabbits through decrease of would contraction rate, increase of revascularization, reepithelialization and fibroplasia.

  • The purpose of this study was to investigate the effects of a protein-free, standardized dialysate/ultrafiltrate (HD) derivatives from calf blood (Solcoseryl$^{(R)}$) for second-intention full-thickness skin wound healing in dogs. Three $2{\times}2cm$ area-matched full-thickness skin wounds were created bilaterally on the dorsolateral aspect of the trunk of nine dogs. In each dog, two wounds were treated with HD, cemella asiatica extract (Centrasol$^{(R)}$) and normal saline, respectively. For six weeks, the wounds were evaluated grossly for contraction, epithelialization and healing and were examined histopathologically. In the first week of the wound healing period, HD stimulated wound contraction and healing more significantly than centasol and normal saline (p<0.05). Neutrophils were more increased in the HD-treated wounds than those in centasol or normal saline treated wounds. In the second week, HD stimulated epithelialization more significantly than centasol or normal saline (p<0.05), and neovascularization and granulation more increased in the HD-treated wounds than those in centasol and normal saline treated wounds. In conclusion, HD was the most effective on early wound contraction, epithelialization and healings among three experimental drugs in full-thickness skin wound.
