This study investigated ginsenosides and tissue characteristics of roots injured by physiological disorder, rusty and rough skin. After separation to cortex and stele parts of healthy, rusty (red) and rough skin roots, respectively, the contents of saponin and ginsenosides were analyzed. And also, the histological and cytological characteristics of cortex and stele parts were investigated. Crude saponin contents were little different among healthy, rusty (red) and rough skin root and ginsenesides as - Rgl, - Re and - Rbl were largely detected both in stele and cortex part. The ratio of PT/PD showed about 1:1 in three kinds of root. In histological study, destoryed cells in epidermis of rusty(red) root, and those in epidermis and exodermis of rough skin root were observed. The cells in cortex of rusty (red) and rough skin root have generally nucleus with unfixed shape, unequal cell wall, large number of vacuole and mitochondris, and unidentified dark substances compared to healthy root. But in cell of stele tissue, most of organellE seems to be normal except a small number of cells in rough skin root.

Objective : Skin barrier protects skin against harmful environment. Its function includes antimicrobial barrier as well as physical barrier. But there are few studies about skin barrier function about men and women who don't have skin disease. The aim of this study is to investigate skin barrier function healthy men and women show. Method : There are many ways to measure skin barrier function, but lately transepidermal water loss is mainly used to know skin barrier function. Transepidermal water loss was measured over eight four the Korean twenties and thirties who don't have skin disease from March 14th, 2007 to March 16th 2007. We surveyed cubital fossa and cheek beside nose to measure transepidermal water loss and used vapometer. Result : After analyzed data, we concluded that cheek showed higher transepidermal water loss than cuital fossa. At cheek, the thirties had higher transepidermal water loss than the twenties. The male got higher transepidermal water loss than the female at cheek and in the average. And temperature and humidity effected on transepidermal water loss. Conclusion: In our study, it was observed that temperature and humidity effected on transepidermal water loss. In traditional korean medicine, the inbalance of cold(寒), heat(熱), dryness(燥), wetness(濕) makes many diseases and the inbalance of them induces dameum(痰飮) and the disorder of blood flow. Dameum(痰飮) and the disorder of blood flow make skin diseases made by abnormal skin barrier function in many ways. So we need to study dameum(痰飮) and the disorder of blood flow to take care of patients who have abnormal skin barrier function.

This study was to set the guidelines of soil chemical components in order to assure the safety and quality of the panax ginseng from physiological disorder. The disorder symptoms appeared on the leaf with yellow spot, atrophy, yellow-brown spot, also showed red skin and rough skin of the root. Occurrence type of physiological disorder in cultivated field divided into two types : type I 'such as, yellow spot' consist of single disorder symptom; type II 'such as, yellow spot and yellow-brown spot' consist of two or more different disorder symptoms. The individual contribution of soil properties to the occurrence type was as follows ; The yellow spot was affected by Na > $NO_3$-N > salinity (EC) in soil. The same results was observed in red skin. Atrophy was affected by $NO_3$-N > salinity (EC) > Ca > Mg. Rough skin was affected by $P_2O_5$>pH>Organic material > K. It showed positive associated to $P_2O_5$, pH and K, but negative associated to organic matter. Simultaneous occurrence of two different disorder, including cases which yellow spot and yellow-brown spot, those were affected by $NO_3$-N > salinity (EC) > Na > Mg. In the case of atrophy plus yellow-brown spot, those also were affected by in the order : $NO_3$-N > salinity (EC) > Ca > Mg > Na. Red-rough skin was affected in the order : salinity (EC) > $NO_3$-N > K > Na. Soil chemical components appear to be related to occurrence of physiological disorder, particularly in salinity (EC) and $NO_3$-N. The salinity (EC) and $NO_3$-N were negative related to plant growth. In addition, exchangeable cation capacity play critical roles in attributing to complex occurrence of physiological disorder.

Psoriasis is an auto-immune skin disease, which is characterized by the excessive generation of plaques on the skin with typically a long-lasting red, itchy and scaly symptoms. Imiquimod, which has been used for the treatment of external genital warts, actinic keratosis, and superficial basal cell carcinoma, induced of psoriasis-like skin disorders with skin erythema and thickness in mice. In the present study, we tried to find the bioactive herbal extract against imiquimod-induced psoriasis-like skin disorder in mice. During the searching of the herbal extract with anti-psoriatic effect, the ethanolic extract of Cnidium officinale ameliorated imiquimod-induced psoriasis-like skin disorder in mice. The morphological evaluation, H&E staining and Psoriasis Area and Severity Index (PASI) score showed that ear and back thickness, and erythema induced by imiquimod were significantly reversed after the treatment of the cream of the ethanolic extract of C. officinale. The overexpressed myeloperoxidase (MPO) and keratin 6A levels were decreased by the treatment of C. officinale cream. Also, $IFN-{\gamma}$, c-fos and $I{\kappa}B-{\alpha}$ mRNA levels, which are related to the progression of psoriasis, were reduced by C. officinale cream. Thus, the ethanolic extract of C. officinale ameliorated psoriasis-like skin disorder induced by imiquimod and might be the therapeutic agent for psoriasis.

Objectives : Biofeedback is a useful non-pharmacological treatment for panic disorder (PD), but no studies have identified physiological markers related to the treatment response. This study investigated predictors of the treatment response for biofeedback in patients with PD. Methods : A retrospective study based on the electronic medical records of 372 adult patients with PD was performed. Patients received biofeedback treatment at least once, and physiological markers including heart rate, heart rate variability, respiratory rate, skin conductance, skin temperature, and electromyography were collected before the treatment began. The patients were classified as responders or non-responders based on the change in Clinical Global Impression-Severity (CGI-S) score. Results : The response rate to biofeedback treatment was 30.4%. Multivariable logistic regression analysis revealed that a higher CGI-S score at baseline and fewer benzodiazepine prescriptions were associated with a better response to biofeedback treatment. According to subgroup analyses, the baseline CGI-S score, dose of benzodiazepines, and skin conductance are candidate predictors of the response to biofeedback treatment in men, while only baseline disease severity was associated with the treatment response in women. Conclusions : The present results suggest that skin conductance may be target marker and predictor for biofeedback in male patients with PD.

과피흑변은 '부유' 단감(Diospyros kaki, 'Fuyu') 과실의 저장 중에 발생하는 주요 생리적 장해의 하나이다. 부유 과실의 과피에서 페놀화합물의 함량, PPO와 POD의 활성, 지질 포화도를 분석하였다. 페놀화합물은 일광의 방향에 따라 과피에 불균등하게 분포하였는데, 일광 노출면에 축적량이 가장 많았고 그 반대면에서는 가장 적었다. 그러나 수관 내부의 음지 가지에서 수확한 과실의 경우 페놀화합물은 과피에 비교적 고르게 분포되어 있었다. PPO와 POD의 활성 또한 과피에서 고르지 않았으나, 이는 과피흑변이 발생한 과실에서만 그러하였으며, 흑변 부위는 PPO 활성은 가장 높고 POD 활성은 가장 낮았다. 수확 시에 일광면에 표식을 한 과실을 저온에 저장하였을 때, 저장 중 과피흑변의 증상인 운형 흑반은 정확히 표식 부위에 발생하였다. 게다가, 일광면은 높은 지질포화도를 보였는데, 이는 일광에 의해 야기된 고온에 대한 적응을 의미한다. 따라서 이러한 결과로 미루어 볼 때, 부유 과실의 과피흑변 장해는 일광에 노출된 과실의 고온 순화 과피 조직에서 나타나는 저온장해 증상의 일종인 것으로 간주할 수 있을 것이다.

Advancement toward aging society has presented the importance of house planning in consideration of the elderly, increasing the necessity of such planning. Therefore the importance of indoor design guideline for elderly houses has been stressed and the understanding of the aging in regard to this trend will create more mature spaces. In line with this trend the purpose of this study is to study the medical factors related with bathroom interior design guidelines of the existing elderly houses from the viewpoint of deteriorating physical functions due to aging process. In order to research the deterioration of physical functions due to aging literatures of medical and exercise physiology were used and concerning the existing bathroom design guidelines for the aged people, the guideline items of behavior facilitation, physiological maintenance and perceptual maintenance aspects out of Murtha & Lee's user benefit criteria(1976) related with physical functions were selected to research in relation with the knowledge about the deterioration phenomena of physical functions. Physical aging and deterioration aspects were classified from the viewpoint of musculoskeletal disorder, cardiovascular disorder, respiratory disorder, gastronomy disorder, urology disorder, somatosensory disorder, endocrine disorder, immune disorder, nervous disorder and skin diseases and these were utilized in interpreting total 100 items of bathroom design guideline. Because bathroom is the space where many physical movements are done, it had the closest relationship with the deterioration of musculoskeletal health in general and as bathroom is the space where people use water and feel the difference in temperature and moisture more than other spaces, deterioration of skin and somatosensory health had the next closest relationship. The result of this study revealed that regarding the deterioration of physical functions of the elderly people in aspect of their perceptibility as designers will design creatively and sincerely based on its relationship with nervous system in future, the result of this study will be used to develop better spatial designs efficiently to meet for the aging society.

Functional medicine is a system which utilizes certain investigative and treatment methods that are primarily oriented toward the recognition of functional disorder. Functional disorders take place on an energetic plane. This plane is not capturable using our regular investigatory techniques, such as X -ray. ultrasound, computer tomography and laboratory analyses. The 7-zone-diagnostic system(VEGA-DFM 722 and ABR-2000, etc) is a diagnostic device Which applies pulse signals to predetermined bodily locations. Applying alternating positive and negative stress to tissues with positive and negative pulses first manifests itself as negative and positive wave forms. The skin has many functions as an organ. It is the organism's interlace with the outsider world. Hence, the manner in which the skin reacts to external stimuli reflects the current state of the organism(as meridian systems). This system make a diagnosis of functional disorder or some typical organic diseases include stress of the mind or the body, and the energetic situation, reserves. We are known a disorder or disease throw the result chart. This result chart contain disorder flow wave forms and some valuable diagnostic hints (letters ; S, OM, RA, etc). In spite of this 7-zone-diagnostic system that is applied plentifully in the clinical application, there is not a statistics which is suitable. Therefor we must carry out many various research in the future.
