This study was carried out to investigate the effects of the wound contraction of chitosan, aloe vera, fucidin natrium, and premycin ointment on defected wound from full-thickness skin defects(1 cm $\times$ 1 cm). Twelve dogs were designed in 5 different positions on the dorsal thoracolumbar. We examined the effects of wound contraction every four other day 16 for days. Percentage of wound contraction based on epitherial overall area of defected wound which calculated by image analyzer and computer. Four to 8 days after wound contraction in wound defected dogs, the epithelial overall rate were the most high presented by 48.1 % in the chitosan group and were the lowest by 26.8% in the premycin group. In 16 days, chitosan group were the most heigh presented by 94.4% and premycin group were the lowest by 76.5% compare to saline group of 85.9%. Thus, we conclude that the chitosan is a possible role for improvement of wound contraction by wound defected dogs.

The effect of urea and urea derivatives on the percutaneous absorption of salicylic acid and sodium salicylate through the skin of rabbit from petrolatum ointment was investigated. It was found that addition of urea or urea derivatives to the ointment base significantly increased the percutaneous absorption of the drugs in proportion to the concentratoin of the additive. The percutaneous absorptoin-enhancing activities of these compounds were that urea derivatives with the more and longer alkyl substituents showed the stronger activities. These activities of urea and urea derivatives were ascribed to the binding of these compounds with the lipids and proteins of the stratum corneum of the skin and the swelling of the tissues, which leads to the reduction of the barrier property of the layer. The preliminary skin irritation test showed that urea and urea derivatives were quite non-irritating to the skin. These results suggest that urea derivatives have a strong possibility to be developed as a percutaneous absorption enhancer.

Gastrodia elata Blume is a well-known kind of natural products used as a folk medicine for thousands of years. However, anti-atopic dermatitis-like effects of G. elata Blume had not been evaluated until now. The aim of the present study is to investigate the protective effects of water extract from the roots of G. elata Blume (GE) on 2, 4-dinitrochlorobenzene-induced atopic dermatitis-like skin lesions using balb/c mice. Combination treatment of GE (at a dose of 12.5 mg/kg body weight by administrated per os + 0.5 mg/cm² as ointment to apply on ear and dorsal skin) was significantly inhibited spleen weight, ear thickness, levels of serum immunoglobulin E and number of mast cells, compared with that of 2, 4-dinitrochlorobenzene-included groups without GE. Furthermore, combination application by oral administration plus by ointment of GE significantly inhibited the histamine release from rat peritoneal mast cells. These results suggest that combination treatment of oral administration plus ointment form of GE could be helpful as a potentially natural pharmaceutical treatment on atopic-like dermatitis.

The process of wound repair involves an ordered sequence of events such as overlapping biochemical and cellular events that, in the best of circumstances, result in the restoration of both the structural and functional integrity of the damaged tissue. An important event during wound healing is the contraction of newly formed connective tissues by fibroblasts. The polypeptide growth factors, like transforming growth factor-${\beta}$(TGF-${\beta}$, insulin-like growth factor I (IGF- I) and epidermal growth factor (EGF), play very important mediator roles in the process of wound contraction. Deer antlers, as models of mammalian regeneration, are cranial appendages that develop after birth as extensions of a permanent protuberance (pedicle) on the frontal bone. Antlers contain various growth factors which stimulate dermal fibroblast growth. They are involved in digestion and respiration and are necessary for normal wound healing and skin health. In order to investigate and evaluate the effects of red deer antlers on skin wound site, the speed of full-thickness skin wound healing and the expression of IGF-I, TGF-${\beta}$ and EGF in skin wounds, three groups of skin full-thickness rat models with a high concentration of antler ointment, a low concentration of antler ointment and without antler ointment were compared. At post-injury days 0, 2, 4, 8, 16, 20, 32, 40 and 60, the skin wound area was measured, the expressions of IGF-I, TGF- ${\beta}$ and EGF mRNA were detected by reverse transcriptase polymerase chain reaction (RT-PCR) and collagen formation by sirius red dye and the localization of IGF-I, TGF-${\beta}$ and EGF peptides were inspected by histological immunohistochemical techniques. Wound healing was significantly more rapid in antler treated skins. In addition, the wound treated with a high concentration antler ointment, a low concentration antler ointment, and the control closed completely at post-injury day 40, day 44 and day 60, respectively. Via RT-PCR, the expressions of IGF-I (day 8 and day 16), TGF-${\beta}$(day 8, day 16 and day 20) and EGF (day 4, day 8, day 16, and day 32) were obviously up-regulated in high concentration antler-treated skins compared to control skins. Similar results could be seen in the histological detection of collagen dye and immunohistochemical methods using the corresponding polyclone antibodies of IGF-I, TGF-${\beta}$ and EGF. These results illustrate that antlers stimulate and accelerate the repair of cutaneous wounds.

An 8-year-old, castrated male Shih-tzu was referred due to relapsing pododermatitis and generalized pruritus. On physical examination, right forepaw showed swelling and serosanguinous exudates from sinus tract on dorsal paw. There were no remarkable findings on complete blood count (CBC), serum chemistry, and radiologic examination. On cytological examination of exudates from sinus tract, phagocyted bacteria and numerous degenerative neutrophils were noted. Results of deep skin scraping and plucking hair examination were unremarkable. Skin biopsy was performed and ruled out other skin diseases. Histopathology showed epidermal hyperplasia and diffuse mononuclear cell inflammation in dermal layer. Moreover, pyogranulomatous inflammation was demonstrated in subcutaneous layer. This case was clinically diagnosed as pododermatitis secondary to atopic dermatitis (AD). Clinical signs of pododermatitis were gradually improved following topical application of tacrolimus 0.1% ointment. This case report describes that tacrolimus ointment can be applicable for the treatment of refractory pododermatitis.

Water-soluble chitin (WSC) was prepared by carefully deacetylating chitins to about $50\%$ of N-acetyl content. Topical formulations based on WSC were prepared and their effects on wound healing were evaluated on a rabbit ear model. Full-thickness, open skin wounds were made on the ears of rabbits and WSC ointments were embedded in the open wounds. The application of WSC ointments significantly accelerated wound healing and wound contraction. The areas of epithelial-ization and granulation tissues in WSC ointment group are remarkably larger than those in control group (no treatment) and in placebo group (treated with ointment-base materials). A large number of grown granulation tissues including dense fibroblast deposition were observed under the thickened epithelium of the wound treated with WSC ointments. The number of inflammatory cells in WSC ointment group was significantly decreased compared with those in control and placebo groups, indicating that WSC would give low stimuli to wounds and prevent excessive scar formation. Neovascularization was the most prominent in WSC ointment group. Wound contraction in WSC ointment group was much larger than those in control and placebo groups. Overall results demonstrate that the topical formulation based on WSC is considered to become an excellent dressing as a wound healing assistant.

Drug delivery system(DDS) applied to various fields, such as medicine, cosmetics, agriculture and necessities of life. Among these application fields, DDS is often used as the method of drug dosage into the epidermic skin. We investigated characters of transdermal therapeutic system(TTS) and the skin permeability of that with applying DDS. Chitosan was selected as material of TTS. We investigated the permeation of chitosan ointment containing drug in rat skin using horizontal membrane cell model. Permeation properties of materials were investigated for water-soluble drug such as riboflavin in vitro. We used glycerin, PEG 600 and oleic acid as enhancers. Since dermis has more content water(hydration) than the stratum corneum, skin permeation rate at steady state was highly influenced when glycerin was used in water-soluble drug. The permeation rate of content enhancer and drug was found to be faster than that of content water-soluble drug only. These results showed that skin permeation rate of drug across the composite was manly dependent on the property of ointment base and drug. Proper selection of the polymeric materials which resemble and enhance properties of the delivering drug was found to be important in controlling the skin permeation rate.

Allergic contact dermatitis is an inflammatory condition associated with periorbital erythema, edema, and pruritus. The periorbital skin is relatively thin compared with the skin over other facial areas; therefore, it is vulnerable to allergen penetration and may show a variety of cutaneous manifestations. Recently, vision enhancement surgery is a widely performed procedure, and the prevalence of senile cataract and glaucoma is increasing. The prevalence of periocular allergic contact dermatitis is increasing secondary to the growing use of topical ophthalmic medications. Several studies in Korea have reported periocular allergic contact dermatitis secondary to the use of topical ophthalmic medications including latanoprost ($Latano^{(R)}$), fluorometholone ($Tolon^{(R)}$), polymyxin B ($Terramycin^{(R)}$), atropine sulfate ($Atropine^{(R)}$), neomycin sulfate ($Cambison^{(R)}$), and befunolol hydrochloride ($Bentos^{(R)}$), among others. However, ofloxacin ($Effexin^{(R)})$-induced allergic contact dermatitis has not been reported in the domestic and/or foreign literature. We report a case of periocular allergic contact dermatitis secondary to the use of ofloxacin ophthalmic ointment.
