Natural moisturizing factors (NMFs) are hydrophilic and water-soluble components in stratum corneum of the skin. NMFs absorb water from outer environment and enhance the water-holding capacity of stratum corneum and thereby, prevent the dryness and increase flexibility and plasticity of skin. NMFs are mainly composed of amino acids and their metabolites that are produced from the degradation of filaggrin. Here we established a simultaneous quantification method for 22 amino acids in tape-stripped stratum corneum samples using UPLC-PDA. With this method, we analyzed amino acid contents from tape-stripped stratum corneum samples of forearm and forehead regions from 15 healthy volunteers. Amino acid contents of inner (or upper) region were higher than outer (or lower) region of stratum corneum. Amino acid contents of stratum corneum of forearm were higher by 1.5 fold than forehead region. Of note, total amino acid contents were significantly and inversely correlated with trans-epidermal water loss (TEWL), an index for skin barrier function. Especially, Ser, Glu, Gly, Ala and Thr were determined to positively affect skin mositurizing activities. In conclusion, we could demonstrate that amino acid contents of stratum corneum are closely linked with skin barrier and moisturizing function, providing an important and fundamental methodology for the study of amino acids in skin physiology.

To evaluate the skin aging inhibition effect of fermented Reynoutria elliptica, skin aging model was produced by the irradiation of UVB to hairless mice for 5 weeks. The skin erythema index for the positive control (PC), not fermented Reynoutria elliptica extract (NFR), and fermented Reynoutria elliptica extract (FR-500, 1000, 2000) groups were lower than that of the control group. However, both lipid and water capacity for the PC and FR groups were higher than those of the control group. Collagen fibers in dermis of the FR groups were almost intact with a regular arrangement which were similar to the normal (NO) group. Also, relatively much less number of mast cells and inflammatory cells were found in FR groups. The skin TBARS contents and XO activity in the FR group were significantly lower than the control group. The activities of GSH, SOD and CAT for the FR groups were significant higher than the control group. Therefore, fermented Reynoutria elliptica extract can be practically useful for the prevention or improvement of skin aging in terms of health promotion and beauty for the people.

The purpose of this study was to systematically evaluate and compare the effects of 640 nm LED irradiation and aromatherapy on the skin condition of the neck. Twenty female participants were divided into Group A (640 nm LED irradiation + aromatherapy) and Group B (640 nm LED irradiation only). Total of 8 experiments were conducted on the 2 groups twice a week. As a result of the experiment, moisture content was significantly improved in both group A (p<0.01) and group B (p<0.001), and wrinkle index was significantly improved in both group A (p<0.01) and group B (p<0.05). Additionally, the change in skin density was significantly improved in both group A (p<0.001) and group B (p<0.05), and the change in elasticity was significantly improved in both group A (p<0.001) and group B (p<0.001) as well. However, the change in skin tone was not significant in group A (p>0.05), but the change was drastically improved in group B (p<0.05). Blemishes and pigmentation changes were significantly improved in group A (p<0.05), but was not significant in group B (p>0.05). These results conclude that combining aromatherapy with 640 nm LED irradiation can be highly effective in improving skin condition of the neck.

Currently, As Plasma application is expanded to the industrial and medical industrial, Low temperature plasma characteristics became important. Especially in Medical industrial, Low temperature plasma directly adapted to human skin, so their plasma parameter is important. One of the plasma parameters is electron density, some kinds of method to measuring electron density are Thomson scattering spectroscopy and Millimeter-wave transmission measurement. But most methods is expensive to composed of experiment system. Heterodyne interferometer system is cheap and simple to setting up, So we tried to measuring electron density by Laser heterodyne interferometer. To measuring electron density at atmospheric pressure, we need to obtain the phase shift signal. And we use a heterodyne interferometer. Our guiding laser is Helium-Neon laser which generated 632 nm laser. We set up to chopper which can make a laser signal like a pulse. Chopper can make a 4 kHz chopping. We used Needle jet as Ne plasma sources. Interference pattern is changed by refractive index of electron density. As this refractive index change, phase shift was occurred. Electron density is changed from Townsend discharge's electron bombardment, so we observed phenomena and calculated phase shift. Finally, we measured electron density by refractive index and electron density relationship. The calculated electron density value is approximately 1015~1016 cm-3. And we studied electron density value with voltage.

Purpose: This study was performed to investigate effects of behavior modification on obesity index, skinfold thickness, body fat, serum lipids, serum leptin in obese elementary school children. Method: Forty seven students were selected from two elementary schools. Twenty four children in one school were assigned to experimental group and twenty three children in another school were assigned to control group. Experimental group was received 60～70 minutes of behavior modification once a week for 8 weeks. Result: Obesity index of the experimental group was significantly decreased after behavior modification. But there was no significant difference between two groups. The increase of skin fold thickness was significantly low in the experimental group compared to the control group. Percentage of body fat and fat mass were significantly decreased in the experimental group. Fat free mass was significantly increased in the experimental group. HDL-C, triglyceride and serum leptin between the experimental group and control group showed no significant difference. Conclusion: These results indicate that behavior modification is effective in decreasing percentage of body fat and fat mass, in less increasing skinfold thickness and in increasing fat free mass. In conclusion, behavior modification can be used as effective strategy for managing obesity in elementary school children.

This study was under taken to investigate the healing of Sa Gun Ja Tang extract (SE) and Sa Gun Ja Tang added Radix Astragali extract (SHE) on the artificial wound on rabbit skin. The granulation tissues were observed by microscope at the five day interval for twenty days. In order to understand the healing mechanism chick embryo culture was carried out in the presence of the extracts and the growth ratio and fusion index were counted. The results obtained were as follows: 1. The healing power of SE treated group on wound was more significant than the control group. 2. The healing power on wound was more effective at the SHE than the SE. 3. The growth ratio and fusion index were higher at the SHE treated groups than the SE treated groups. From the above result, SHE was more effective than the SE on wound healing activity by the mechanism of stimulating the cell growth ratio and fusion index.

We have examined seasonal and annual means of clear-sky solar noon and daily erythemal ultraviolet-B irradiances measured in Anmyeon. The intensity of the EUV-B irradiance is mainly dependent on solar zenith angle (SZA) and total ozone amounts on clear day conditions. The daily maximum occurs near solar noon time and the highest monthly accumulated EUV-B is seen in July in Anmyeon. The maximum daily variation occurs in June and July due to precipitation and clouds. The 7-year trend of EUV-B irradiance shows that it is slightly increasing. Additionally, we could confirm that aerosol effects such as Asian Dust decreases the EUV-B irradiance reaching the ground surface by 35% to 60%. For more than 45% of the summer days, EUV-B irradiacne was high enough that the UV index registered higher than category Extremely High. This information will be very important for evaluation of the UV index for prevention of both skin cancer and ecosystem damages as well as to understand UV climatology over the Korean Peninsula.

Techniques, using physical wedge filter and using dynamic wedge filter and FIF(Field in Field) and ISCT(Irregular Surface Compensating Technique), have been developed according to progress of radiation therapy of breast cancer. Measurement of dose was done to judge the usefulness of technique using three cases, non tissue loss after breast conserving operating and tissue loss after breast conserving operating and mastectomy. Dose indexes of breast tissue, CI (Conformity Index), HI (Homogeneity Index) and QOC (Quality of Coverage), dose index of skin, or dose indexes of lung, volume of 50 percent dose and 20 percent dose were estimated and compared. Using dynamic wedge filter is useful plan at non tissue loss allowing for high dose of lung. FIF and ISCT are useful plan at tissue loss. ISCT is useful plan at mastectomy. Henceforth, we need to apply to valid plan and body type and thorax size.

Purpose: In performing breast reconstruction, making symmetrical breast is still a challenge. A precise estimate of the volume of the breast specimen is necessary to reconstruct a symmetrical and aesthetically pleasing breast. This study aims at finding out the relationship with breast tissue density and body mass index designed to apply for breast reconstruction. Methods: By using the Archimedes' principle, the authors calculated the volume of the breast specimen and drew a correlation between the density of breast specimen and BMI. From October 2002 to November 2004, this method was used on 197 patients to predict breast volume for TRAM flap reconstruction. Results: The mean density was 0.9954g/cc and had no correlation with BMI (p-value=0.069). There was no difference between denstiy of breast tissue after skin spared mastectomy and that of breast tissue after nipple spared mastectomy. Conclusion: These data will be helpful to predict the needed volume for breast reconstruction.
