Background Repair of facial laceration in the emergency department can pose a number of difficulties. Children can be uncooperative, but adults can also be if they have sustained head trauma or are intoxicated. Leukosan SkinLink consists of topical adhesive and adhesive tape that can be applied easily to long or tense wounds. In this study, the authors compared conventional suturing with Leukosan SkinLink for facial laceration patients in the emergency department. Methods The prospective study was carried out from March 2013 to September 2013 with linear facial laceration patients visiting the emergency department. Exclusion criteria were open fractures, joint injuries, skin defects, hairy skin, and mucosa. The author used Leukosan SkinLink for skin closure in the experimental group and used conventional suturing in the control group. The scar evaluation using the Patient and Observer Scar Assessment Scale (POSAS) along with satisfaction scores, procedure times, and complications were compared. Results A total of 77 patients (30 in the control group and 47 in the experimental group) participated and underwent follow-up for 6 months postoperatively. The scar assessment using the POSAS and the satisfaction score in both groups were similar. The average procedure time in the experimental group was shorter. In the control group, there were four cases of wound dehiscence, two of infection, and one of skin necrosis, whereas four cases of wound dehiscence and one allergic reaction occurred in the experimental group. Conclusions With a simple application technique, Leukosan SkinLink is a new effective method for facial laceration repair especially useful for children and uncooperative adults.
Objectives : The Skin is composed of multiple layers, including the epidermis, dermis, and hypodermis. It provides a vital barrier structure that protects vertebrates from external environmental antigens, solvents, ultraviolet light, microorganisms, toxins, and weather conditions. Although several biological effects of Mori Follium have been reported, beneficial effects of Mori Follium in skin health remain unclear. In this study, we prepared water extract of Mori Follium (MLE) and evaluated the effects on melanin accumulation and expression levels of skin fibril-related proteins.Methods : The cytotoxicities of MLE in B16F10 melanoma and human skin fibroblasts (HSF) were examined by MTT assay. Inhibitory effect of MLE on the α-MSH- and IBMX-induced melanosis in B16F10 melanoma was examined. The expression levels of fibronectin, collagen 1α2, and CCN2 in MLE-treated HSF were analyzed by reverse transcription-polymer chain reaction (RT-PCR) and western blotting.Results : The MLE treatment for 24 h did not affect to the B16F10 and HSF at concentrations of 1, 10, 50, 100, 200, 400 and 800 ㎍/ml. The MLE treatment for 72 h significantly and dose dependently suppressed melanin accumulation in B16F10 melanoma. In addition, the MLE treatment up-regulated expression levels of skin fibril-related genes such as fibronectin, collagen 1α2, and CCN2 in HSF. Our western blot analysis revealed MLE-induced up-regulation of skin fibril-related genes required the activation of CCN2 protein.Conclusions : In conclusion, these findings suggest that the MLE could be used in development of cosmetic natural material of maintaining healthy skin.
Objective: The purpose of this study was to investigate the effects of skin application with Gelidium amansii extract on skin with deep second degree burns in mice. Methods: BALB/c mice were divided into four groups: normal (NOR) group; burn-elicited mice (CON) group, Silmazine-treated mice after burn elicitation (ST) group, and Gelidium amansii-extract treated mice after burn elicitation (GT) group. To examine the skin recovery effect after burn, changes of burn area, angiogenesis and histologic structure were analyzed. To measure effect of edema regulation, matrix metalloproteinase-9 (MMP-9) was analyzed. To estimate the skin regenerative & stable effect, 5-bromo-2'-deoxyuridine (BrdU) and substance P were analyzed. Results: 2 weeks later, 1. The size of burn area decreased in the GT and ST groups more than the CON group. 2. Alleviation of angiogenesis appeared in the GT and ST groups more than in the CON group. 3. Blood clot, epithelial cell hyperplasia, and inflammatory cell infiltration declined in the GT and ST groups more than in the CON group. 4. MMP-9, BrdU, and substance P positive reaction decreased in the GT and ST groups more than in the CON group 5. In the comparative study, the GT group was superior to the ST group. Conclusion: The skin application of Gelidium amansii extract could lessen skin damage by the medium of regulation MMP-9 activation. This skin stabilization was induced in mice with deep second degree burns.
This study was to evaluate the effect of the moisturizing cream containing five kinds of plants extracts for human facial improvements such as hydrating ability, transepidermal water loss and erythema reaction. The antioxidant activities of yellowish natural colorants, extracted from five kinds of plants (Ceramium kondoi, Phellodendron amurense, Carthamus tinctorius, Gardenia jasminoides for. grandiflora and Aphis chinensis) were tested. Twenty-one volunteers were subjected to analyze the effects, and each result was determined by treating the complex cream containing plants extracts on their skin in three times. The moisture content on skin was significantly increased more than 50% by treating the cream containing five kinds of plants extracts. The transepidermal water loss was reduced and the level of the skin erythema reaction was improved after treatment of the complex cream. Survey analysis showed that the volunteers had highly satisfaction on the tested creams. The results suggest that the complex cream containing five plants extracts had an improved effect on facial skin, and therefore can be used as moisturizing ingredients in the related industry.

Objectives Hataedock method is a Korean medical therapy which removes fetal toxin by orally administering herbal decoction to neonates. This study was to observe skin damage and anti-inflammatory effect via regulating IL-4 activity in NC/Nga mice which were induced atopic dermatitis (AD)-like skin lesion by Dermatophagoides (D.) farinae after applying Douchi Hataedock method. Methods NC/Nga mice with 3 weeks of gestational age were used. Each 10 mice were allocated to the control group (Ctrl), the AD-induced group (AE), and the group which induced AD after administering Douchi extract (GT). After 4 weeks from administering Douchi extract to the mice, the primary AD was induced by applying D. farinae extract 6 times per week for 3 weeks and then the secondary AD was induced by the same method after 1 week from the primary AD induction. To identify the skin damage and anti-inflammatory effect, we observed LxR, IL-4, Fc ${\varepsilon}$ receptor, substance P, and $NF-{\kappa}B$. Results The GT group showed alleviation of skin injury and decrease in capillary angiogenesis. Stratum corneum damage, epithelial cell hyperplasia, lymphocyte infiltration, and capillary distribution relatively decreased in the GT group. LxR-positive reaction in the GT group were increased by 53% than that of the AE group. IL-4 production, $Fc{\varepsilon}$ receptor activity, and substance P-positive reaction in the GT group were decreased by 82%, 42%, and 82% respectively compare to those of the AE group. $NF-{\kappa}B$-positive reaction in the GT group were decreased by 15% compare to that of the AE group. Conclusions Hataedock method with Douchi extract alleviated AD via reducing inflammatory cytokines secreted at the early stage of AD. Thus, Douchi Hataedock method has a beneficial effect for the prevention and treatment of AD.

Nowadays, ceramides have been found to be an important component in the outermost layer of the skin - the stratum corneum. It is undersrood that ceramides play an important role in structure and maintenance of the interellular lipid lamella structure in the SC layer. Thus, many efforts have been made by the cosmetics and pharmaceutical industries to get human skin-identical ceramides or pseudoceramides which show similar performance with natural ceramides. The purpose of our study was to systhesize new pseudoceramides via an effective and economical systhetic pathway and to show their performance of skin restoratio. Four kinds of the new pseudoceramides were synthesized by the reaction of alcoholic amine and alkyl ketene dimer. First of all, PC-4 and PC-5 were synthesized by the reaction of 3-amino-1,2-propanidiol and serinol with alkyl ketene dimer respectively. After that, PC-4R and PC-5R were produced by changign kitone group at $\beta$-position to amide bond of above synthesized PC-4 and PC-5 into hydroxyl group using NaBH4 respectively. Their expected structures were conformed by the NMR, IR spectra, and elemental analysis. A study to show the restoration effectiveness was performed in which human skin was pretreated with high concentration of SDS surfactant solution. Using 0.5% solution of above synthesized pseudoceramides, there was the significantly faster restoration of the damaged than that of placebe itself treatment.
This study has evaluated the physiological reaction to wearing brassiere as well as the sensations that the wearer feels in order to understand the effect of brassiere use on the human body. Six healthy women in their twenties were used as subjects and the experiment measured the difference in their S.C.L, Skin Temperature, B.V.P and Pulse. The measurements were made in the following conditions: Women not wearing any brassiere, women wearing sports brassiere, and the women wearing wire brassiere. The results showed significant differences in the following areas. 1. S.C.L was found to be the highest when they didn't wear any brassiere, followed by when they wore wire-brassiere and then sports brassiere. 2. The Skin Temperature was found to be the highest when they wore wire-brassiere, followed by when they wore sports brassiere and when they didn't wear any of them. In particular, when they wore sports brassiere, the B.V.P was found to be the highest when they wore none of them, fir skin temperature dropped as time passed. 3.ollowed by when they wore sports brassiere and then wire brassiere. When they wore sports brassiere, they had irregular blood-flow. 4. Pulse was found to be the highest when they didn't wear any of them, followed by when they wore sports brassiere and then wire brassiere. 5. Those who didn't wear any brassiere felt the most chill, followed by those wearing wire brassiere and then sports brassiere. The moisture level was found to be the highest when they wore sports brassiere, followed by when they wore wire brassiere and then when they wore none of them. Comfort level was found to be the best with no brassiere, followed by wire brassiere and then sports brassiere.

Paragonimus infection is prevalent in Korea, establishing several endemic foci. Kim(1969) reported an endemic area in Hyeonbuk Myeon. Yangyang-Gun, but thereafter no further epidemiologic study of Paragonimus infection was performed in the Gangweon-Do. Hoengseong-Gun is mountainous area which is located in the southwestern part of Gangweon-Do and borders with Hongcheon-Gun on the east, with Pyeongchang-Gun on the east, with Yeongweol-Gun and Weonseong-Gun on the south, and with Yangpyeong-Gun on west. The author carried out an epidemiologic study of Paragonimus infection by intradermal test with V.B.S antigen, and of intermediate host (crayfish) in Hoengseong-Gun, Gangweon-Do. The results are summarized as follows: 1. The positive skin test reaction to Paragonimus antigen was 14.5% from 2,807 examiness; 16.0% in male and 11.6% in female and no sex or age difference on the skin test positive reactions was noticed among the villages. 2. The positive skin test reactions were 31.3% in Gapcheon-Myeon, 20.5% in Cheongil-Myeon and 19.8% in Woocheon-Myeon. Primary school children in Byeongjibang-ri, Gapcheon-Myeon showed positive in 36.4%. 3. The prevalence by skin test reaction by social strata was 16.1% (226 out of 1,408) in primary school children, 12.8% out of 725) in middle school, 6.4% (11 out of 172) in high school students, and 15.3% (77 out of 502) in inhabitants of Heongseong-Gun. 4. Metacercarial positives of Paragonimus in crayfish were 20.9%. Through the survey results, it is postulated that Heongseong-Gun, Gangweon-Do is to be categorized as an endemic area of Paragonimus infection.
Both immune reaction and hypersensitivity reaction are occurred by the same mechanism, the antigen and antibody reaction. The favorable result of this reaction towards a host is called clinically an immune reaction and the opposite results is called an hypersensitivity reaction. Type IV hypersensitivity reaction is a delayed type which is related to the cellular immune reaction and a contact hypersensitivity is included in this type. Various dental materials such as metal (mercury, nickel, chrome, cobalt), resin and eugenol are etiologic substances. Patch test kit is composed of test substance with a controlled concentration which respond only to a susceptible patient and an aluminum chamber, and etiologic substances for hypersensitivity can be easily and comfortably found just by applying the kit to the patient's skin. In this case report, the patch test was performed to a patients with oral lichen planus and the allergen, restorative material was found. After removal of the matching restoration from the patient's mouth, the symptom was improved.
Early wound healing responses in the skin of the Korean fire bellied toad, Bombina orientalis, were examined using histochemical , scanning and transmission electron microscopical techniques. Cutaneous wounds were induced by sharp razor blade , and maintained in special cages for up to 3 days. By this treatment whole parts of epithelium and dermis were profoundly affected. After injury, retraction of damaged surface of the skin was observed. At 3 hours after injury, poly-band was form by mucous substance. The wound skin consisted of mucous gland secreted mucous substance which flows into wound cavity and the wound area was sealed by mucous substance which form thick layer at 6 hours. It appeared that natural disposition showed acid and neutral mucous substance by reaction of PAS and Alcian blue (pH 2.5) staining. After formation of the poly-band, epithelial cells were formed by migration of regenerating epithelial cells. These cells moved over the wound surface by migration at 12 hours after wounding. Poly-band was much increased in thickness and migrating cells were completely formed wound closure at 24 hours post-wounding. After 72 hours regenerated epithelial layer consists of four or five cell layers which are similar to clear, granular, and spinous layer.
