본 연구에서는 연령별 수분함유량, 유분함유량 및 경표피수분함유량에 대한 데이터를 비교 분석함으로써 연령별 피부 특성 차이를 규명하여 향후 화장품 산업개발에 도움을 줄 수 있는 기초자료를 제공하고자 한다. 피험자 남녀 총 638명을 대상으로 볼 부위의 수분함유량, 코 끝 부위의 유분함유량, 볼과 전박부위의 경표피수분손실량을 측정하였으며, Statistical Package for the Social Sciences (version 19.00; SPSS Inc., Chicago, IL, USA) 프로그램을 사용하여 분석하였고 피험자에 대한 정보뿐 아니라 피부 수분함유량, 유분함유량, 경표피수분손실량의 피부 측정치 결과를 평균 ± 표준편차로 나타내었다. 그 결과 볼 부위의 수분함유량은 여성이 남성보다 높았으며, 연령이 높아질수록 수분함유량이 증가하였다. 또한 코 부위의 유분함유량은 남성이 여성보다 높았으며 연령이 낮아질수록 유분함유량이 증가하였다. 볼 부위의 경표피손실량은 여성이 남성보다 높은 반면, 전박 부위의 경표피손실량은 남성이 여성보다 높았다. 이상의 연구 결과로 추후 화장품 산업에서 연령별, 성별 기초화장품 개발 등에 도움을 줄 수 있는 기초자료로 활용될 수 있을 것이라 사료된다. In this study, water content, sebum content, and transepidermal water content were investigated to provide basic data for the future cosmetics industry as comparing the skin characteristics of different ages. Water content of cheek area, sebum content of nose area, and transepidermal water loss (TEWL) of cheek and forearm of trial subjects (total 638 people of both male and female) were measured. Data were analyzed using Statistical Package for the Social Sciences program (version 19.00; SPSS Inc., Chicago, IL, USA). Water content, sebum content, and TEWL of skin were measured as mean ± standard deviation. As a result, water content of cheek from female was higher than male and the water content increased with the older ages. However, sebum content of nose from male was higher than female and the sebum content increased with the younger ages. TEWL of cheek from female was higher than male, but TEWL of forearm from male was higher than female. Therefore, these results can be used as basic data in the development of future cosmetics for different ages and genders.

본 연구는 자외선 차단지수(Sun protection Factor, SPF) 측정 시험에서 피험자의 안전을 확보하고 정확한 시험결과를 통해 향후 자외선 조사시험의 기초 데이터 확보 및 연구자료 마련을 목적으로 하였다. 피부유형 기준표에 따라 피험자의 피부유형 Ⅰ, Ⅱ, Ⅲ 형에 해당되는 피험자 395명을 대상으로 하였다. 색차계를 이용하여 피부색을 측정한 뒤 ITA (Individual Typology Angle) 값을 계산하고 그 값이 28 이상인 사람을 대상으로 편안한 자세를 취하도록 하여 자외선을 60 s 간 조사한 후 24 h 뒤 피험자의 홍반 상태를 판정하였다. 전면에 홍반이 나타난 부위에 조사한 UVB의 광량 중 최소량을 최소홍반량(Minimal Erythema Dose, MED)으로 하였다. 통계학적 분석은 Statistical Package for the Social Sciences 프로그램을 사용하였다. 피부 유형이 높아질수록 MED 값이 증가하여 피부색이 어두워질수록 MED가 증가한다는 결과를 얻을 수 있었다. 또한 여성이 남성보다 높은 MED로 여성이 남성보다 어두운 피부유형을 가진 것으로 나타났고, 연령별 MED는 피부타입별 모든 연령대에서 연관성이 없었으나 이 같은 결과를 단정 짓기에는 성별, 연령대별 피험자 수가 적어 통계적 유의성을 뒷받침하는데 한계가 있을 것으로 생각된다. 본 연구를 통해 얻은 피부유형별 MED 측정값은 자외선 차단제를 사용하기 전 MED 값을 예상하여 자외선차단제의 효능 평가 시 비교, 판독을 할 수 있는 기준이 되므로 임상에 안전하게 적용할 수 있는 기초자료로써 유용하게 쓰일 수 있을 것이다. In this study, ultraviolet protection factor (Sun Protection Factor, SPF) was investigated to provide basic data for subject safety and research of ultraviolet (UV) irradiation test in the future. Trial subjects (395 people) of skin type Ⅰ, Ⅱ, and Ⅲ were evaluated according to skin type standard table. After measuring the skin color using a colorimeter, ITA (Individual Typology Angle) value was calculated. Subjects with 28 and above ITA value were positioned comfortably to be UV irradiated for 60 s and erythema was evaluated 24 hours after application. MED (Minimal Erythema Dose) was investigated where the minimal amount of erythema existed among UVB irradiated area. Statistical analysis was investigated using Statistical Package the Social Sciences program. As a result, the darker skin color results in the higher MED value since the higher skin type number results increased MED value and female has higher MED value than male since female has darker skin type than male. There was no relation between MED difference by ages in all different ages. However, it is hard to draw a conclusion as above since the number of subjects were not sufficient to support statistical significance for MED values by different ages. However, MED values by skin types obtained through this study can be used as a standard when MED value is expected to evaluate efficacy of sunscreen product and as basic data for further safety of clinical researches.

Objective : Recently, obesity has increased at an alarming rate and is now a worldwide health problem. Natural dietary supplement, $CharmSlim^{(R)}$(C), is mixed pills, which consists of beans, black sesames, kelps, onions, adlay seeds, anchovies, pyogo mushrooms, green tea. Our study was performed to determine the weight-loss effects of natural dietary supplement, based on natural ingredients, in mice fed high-fat diet with an abundance of carbohydrates. Methods : Four groups of male ICR mice were fed different diets during 6 weeks: normal diet(NOR), high-fat (15%, w/w) diet(HF), high-fat supplemented with natural dietary supplement powdered 5%(C5) and 10%(C10) groups. We measured the changes of food intake, body weight and adipose tissues weights. Also we examined levels of lipid profiles in serum. Results : Body weight, liver weight and food efficiency ratio were significantly higher in the HF group than in NOR group. After 6 weeks of treatment, body weight, liver weight and adipose tissues weights (epididymal, perinephric, visceral and BAT) were significantly decreased in the C10 group when compared to the control HF group. The C10 group had markedly lower serum levels of total cholesterol and triglyceride when compared with HF group. Conclusion : These results demonstrate that this dietary supplement can suppress the increased lipid profiles, body weight and fat gains, thus could be considered as an effective adjunct in the treatment of obesity.

Objectives : This study was conducted to investigate the anti-obesity effects of mixed water extract of Plantaginis Semen & Poria (CJB) on obese rats induced with high fat diet. Method: Male Sprague-Dawley rats were divided into three groups; Normal group, high-fat (HF) group, HF+CJB(100 mg/kg, P.O.) for 8 weeks. The body weight, food intake and weights of adipose tissues were measured, respectively. Lipid profiles in serum were analyzed by automatic analyzer of blood. Obese marker proteins and the changes of NPY and LR immunoreactivities in hypothalamus were analyzed by Western blot and immunohistochemistry. Results : CJB significantly reduced body weight, food intake, adipose tissue weights compared to HF group. Serum triglyceride and total cholesterol were significantly higher in HF group than in Normal group however, CJB significantly lowered those of HF group. HDL-cholesterol level in CJB groups was elevated compared to HF group. The pAMPK in hypothalamus were decreased in that of HF group and that of CJB group decreased. Inversely, ACC was increased in HF group and that of CJB groups decrease. Expression of PPAR□ in hypothalamus was increased by CJB treatment. However, PPARα levels in CJB group were decreased compared to HF group. The expressions of NPY and LR in PVN and ARC of hypothalamus were decreased in CJB group, respectively. Conclusion : Administration of CJB can play anti-obesity through regulations of NPY and LR activities and obesity marker proteins in obese rat`s hypothalamus.

최근 화장품을 사용하는 인구가 증가함에 따라 세안의 중요성도 강조되고 있다. 회전 브러시를 이용한 세안은 이전부터 산업계에서 적용되어 온 방법이나, 국내 문헌상 회전 브러시를 이용한 클렌징 기기의 세정효과에 대한 연구가 보고된 바가 없는 실정이다. 본 연구는 회전 브러시를 장착한 클렌징 기기인 PBRCF1201(Amorepacific Co., Korea)에 대한 세정력과 피부상태 개선효과에 대한 실험 결과를 보고한다. 총 20명의 환자가 참여하였으며, PBRCF1201를 사용하기 전 블랙헤드, 세정력(피부 밝기), 피부 각질, 모공, 유분함유량에 대해 측정을 하였고 시험제품을 1회 사용하게 한 후 동일한 항목을 측정하였다. 평가 대상 부위는 얼굴과 전박부를 대상으로 하였다. 그 결과 클렌징 젤을 단독으로 사용할 때보다 클렌징 젤과 클렌징 기기를 사용하였을 때 통계적으로 유의한 차이를 나타내며 더 좋은 세정력을 나타냈으며 피부 각질, 블랙헤드, 유분 함유량, 모공 개수 역시 감소하였다. 결론적으로 회전 브러시를 장착한 클렌징 기기는 피부에 손상이나 건조를 유발시키지 않는 효과적인 세안방법이라고 생각된다. Recently, the importance of cleansing is emphasized according to increasing use of cosmetics. Even though many cleansing devices with a rotating brush are commercially available, there are no reports about cleansing devices with rotating brushes in Korean literature. In the present study, we evaluated the efficacy of cleansing device with a rotating brush which was named PBRCF1201 (Amorepacific Co., Korea). 20 volunteers were enrolled in this study. Before and after use of PBRCF1201, we measured the number of black head, skin brightness, desquamation index, sebum, and the number of pores on the face and forearm. Cleansing by cleansing device with a rotating brush was shown to cleanse better than manual cleansing. In addition, the number of black heads, skin brightness, desquamation index, sebum and the number of pore were also improved after cleansing. Therefore, the cleansing device with a rotating brush appears to be an effective cleansing method without causing injury or dryness.

Background: The choice of topical agents is very important for patients with atopic dermatitis (AD) because mild to moderate AD-related symptoms and skin lesions could be significantly relieved with appropriate topical treatment. This study was performed to evaluate the effectineness of a mixed herbal extract lotion containing the extract of Sophorae Radix, Cinnamomi Cortex, Saururi Herba Seu Rhizoma and Aurantii Immaturus Fructus in relieving symptoms and skin lesions associated with AD. Methods: A total of 24 patients who were suffering mild to moderate AD applied topical lotions, i.e. the test lotion on the right antecubital fossa and the control lotion on the left antecubital fossa twice daily for up to 4 weeks. The treatment efficacy was evaluated by the measurement of skin hydration and trans-epidermal water loss (TEWL) on the same site at each visit. Additional evaluation methods were the investigator global assessment (IGA) and the visual analogue scale visual analogue scale for pruritus. Results: The test lotion-applied right antecubital fossa achieved more clinical improvement than the control lotion-applied left antecubital fossa. TEWL on the test side more significantly decreased than that on the control side after 4 weeks of lotion application. There were slightly more improvements in both the IGA and patient assessment of pruritus on the test side. Conclusion: Mixed herbal extract lotions containing the extracts of Sophorae Radix, Cinnamomi Cortex, Saururi Herba Seu Rhizoma and Aurantii Immaturus Fructus can relieve symptoms, such as pruritus, in AD patients.
