Objective : This clinical research was conducted to test patients with Atopic Dermatitis by external application with Yeongyuseungmatang in cosmetics. Methods : We gave scores to 33 patients who visited the Dept. of Oriental Medical Opthalmology & Otolaryngology & Dermatology of Semyung Jecheon Oriental Medical Hospital from April 17th, 2008 to June 12th. Seventeen patients were treated with Yeongyuseungmatang(Experimental group) and sixteen patients were treated with Atopico skin care cream(Control group) for 4weeks. We observed change of total IgE, eosinophil count, Skin Temperature, Transepidermal Water Loss(TEWL), Skin Hydration and Skin pH. Also Clinic Index of Atopic Dermatitis(SCORAD Index) and global assesment of efficacy were used to evaluate the effects of Yeongyuseungmatang. Statistical analysis was performed by using frequency analysis and descriptive analysis. Statistical significance was achieved if the probability was less than 5%(p<0.05). Results : 1. After 4 weeks of external application treatment, SCORAD Index in Yeongyuseungmatang was significant statistically decreased compared with control group. 2. After 4 weeks of external application treatment, eosinophil count in Yeongyuseungmatang was significant statistically decreased compared with control group but total IgE was very increased both Yeongyuseungmatang and control group. 3. Statistically, Yeongyuseungmatang and control group didn't showed significant effect on Skin Temperature was measured by Thermometer SM815. 4. Transepidermal Water Loss(TEWL) in Yeongyuseungmatang was significant statistically decreased compared with control group measured by Tewameter TM300. 5. Skin Hydration in Yeongyuseungmatang was significant statistically increased compared with control group measured by Corneometer CM825. 6. Statistically, Yeongyuseungmatang and control group didn't showed significant effect on Skin pH was measured by Skin-pH-Meter PH905. 7. After 4 weeks of external application treatment, Yeongyuseungmatang showed significant effect on global assesment of efficacy. Conclusion : Considering the above results, we can speculate that cosmetics with Yeongyuseungmatang has some therapeutical effects in mitigating the symptoms of atopic dermatitis.

Fructose 1,6-diphosphate(FDP), a glycolytic metabolite, is reported to ameliorate inflammation and inhibit the nitric oxide production in murine macrophages stimulated with endotoxin. It is also reported that FDP has cytoprotective effects against hypoxia or ischemia/reperfusion injury in brain and heart, and may play a protective role in ultraviolet B (UVB, 280~320 nm)-injured keratinocyte by attenuating prostaglandin (PG)-E$_2$production and cyclooxygenase (COX)-2 expression, which are possibly through blocking the intracellular reactive oxygen species (ROS) accumulation. Therefore FDP is considered to act as a potent antioxidant especially in the skin. We conducted the several safety tests (single-dose toxicity, primary skin irritation test, eye irritation test, skin sensitization test, phototoxicity test, photosenitization test and human patch test) to see if FDP is safe in case used for the skin application. Our data obtained hitherto suggest that FDP is very safe if applied to the skin.

Purpose: This experimental study was to verify the effects of the mineral oil on skin under casts for relief of skin dryness and pruritus. Method: Participants in the study were inpatients at C university hospital in D city who had long leg casts. The mineral oil was applied to the skin under the casts in the experimental group of 18 patients and was not applied to the control group, also 18 patients. During the experimentation, the participants in the experimental group were informed about how to apply the mineral oil and 1 week later were responsible for applying the oil themselves. The oil was applied three times a day. Data collection was done from July 28, 2002 to September 28, 2002. The analyses were carried using frequencies, percentages, $x^2$-test, t-test, and repeated measures ANOVA with the SPSS WIN 10.0 program. Results: Hypothesis 1, 'The experimental group using the mineral oil application showed remarkably less dryness in the skin compared to the control group' was accepted (F=16.39, p=0.000). Hypothesis 2, 'The experimental group using the mineral, oil application showed remarkably less pruritus compared to the control group' was accepted (F=34.01, p=0.000). Conclusion: These results demonstrate that mineral oil application to skin under casts was effective in treating skin dryness and pruritus. Accordingly, it is concluded that mineral oil application to skin under casts can be an effective nurse intervention to treat skin dryness and pruritus.

To investigate the skin toxicity of xylene, xylene (25 mg/$\textrm{cm}^2$) has been sequentially applied to the rat skin for four days. On the light microscopic examination, epithelium was left out with infiltration of inflammatory cells in border with dermis, and formation of new epithelial layer was shown under the inflammatory zone. Application of xylene to the rat skin showed the marked rise of cutaneous xanthine oxidase activity whereas, He activities of oxygen free radical scavenging enzymes, superoxide dismutase and glutathione S-transferase, were significantly declined. Furthermore, the content of cutaneous glutathione was more and less decreased in rat skin applied with xylene. In conclusion, these results suggest that a part of oxygen free radical may be responsible for morphological changes in skin by applying xylene to the rat skin.

The most effective modality for cold application and the length of the application have not been determined despite many studies about the use of cold. A quasi-experimental study was conducted to examine the most effective modality among three methods of cold application, the most effective length of time for the application and the continuing effect after each type of cold application. Thirty adult patients admitted to medical and neurosurgical unit and with high fever (above 38.2 ℃) were assigned randomly to each of three cold ap-plication methods : (a) ice bag: (b) cold compress; and (c) tepid water sponge bath. Each method was applied to the whole anterior surface except the face and neck with the patient in the supine pos-ition. Rectal temperatures and skin temperatures (mid chest, upper arm, thigh and leg) were measured be-fore each application and every 10 minutes during ,each application for a period of 60 minutes. They were also measured every 10 minutes for 30 minutes after each cold application was finished. The experiments were carried out from Dec. 22. 1992 through Feb. 26, 1993. The data were analysed using means, ANCOVA Sheffe test and Pearson's Correlation Coefficient. The results of this study are as follows : 1. There were no significant differences among the three cold application methods in the reduction of body temperature, 2. Among the ice bag, cold compress and tepid water sponge bath groups, the ice bag proved to be the most effective method for lowering skin temperature while the cold compress was least effective. 3. Both rectal and skin temperature continued to decrease during the 60 minutes of cold application, but the hunting phenomena was not observed at any of the cold application sites. 4. There were no significant correlations between mean rectal and skin temperatures. 5. Skin temperatures according to the cold application sites decreased to a range of 3.46℃ to 5.20℃ (mid chest), a range of 4.48℃ 4.96℃ (upper arm), a range of 3.86℃ to 5.05℃ (thigh), and a range of 5.42℃ -7.12℃ (leg ). 6. In continuing effect after the cold applications were finished, rectal temperatures according to ice bag, cold compress and tepid sponge bath decreased to 0.29℃, 0.23℃ and 0.09℃ respectively, while the mean skin temperatures increased to 2.39℃ , 2.04℃ and 2.22℃ respectively. In this experiment the ice bag was the most effective modality for lowering skin temperature. when-ever cold is applied for systemic effect, the continuing effect of cold should be considered. The determination of the most effective length of time for cold application needs further study.

This paper presents an approach for detecting and measuring human skin pigmentation. In the proposed scheme, we extract a skin area by a Gaussian skin color model that is estimated from the statistical analysis of training images and remove tiny noises through the morphology processing. A skin area is decomposed into two components of hemoglobin and melanin by an independent component analysis (ICA) algorithm. Then, we calculate the intensities of hemoglobin and melanin by using the location histogram and determine the existence of skin pigmentation according to the global and local distribution of two intensities. Furthermore, we measure the area and density of the detected skin pigmentation. Experimental results verified that our scheme can both detect the skin pigmentation and measure the quantity of that and also our scheme takes less time because of the location histogram.

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.
