The purpose of this study was to measure and compare the skin temperature over the exercised muscle and corresponding non-exercised muscle after unilateral isokinetic exercise using digital thermography. Thirty-two young healthy volunteers with no history of knee injury were tested. After isokinetic exercise at 60 degree per second angular velocity using the right leg in a climatic chamber at ambient temperature of $23-26^{\circ}C$, skin temperature of the anterior thigh was tested. After exercise, the skin temperature of both the right and left leg had fallen significantly. The skin temperature of the exercised leg fell less than that of the non-exercised leg. The fall in skin temperature after work was not due to increased evaporative cooling, but was the result of segmental vasoconstriction probably caused reflexly in the spinal cord by non-thermal afferents from exercising muscle or moving tissues. The effect of thermoregulatory vasodilation was reduced by reflex vasoconstriction caused by non-thermal factors such as catecholamine.

Several structural proteins present in keratinocytes of the skin are known to play an important role in the formation of epidermal tissue and barrier function, and the absence of structural proteins in keratinocytes causes various skin diseases. In this study, 42 types of tetrapeptides derived from the sequence of Loricrin, a kind of terminally differentiating structural protein, were synthesized, and skin anti-aging properties were measured by measuring the elastase inhibition, proliferation of skin cells. The anti-aging efficacy was verified and, based on this, it succeeded in selecting one of the most excellent peptides. It is expected that the selected tetrapeptide can be used as a raw material for various cosmetics and quasi-drugs based on anti-aging and skin cell proliferation effects.

Sasang Constitutional Medicine (SCM) suggests the concept of health condition which is owned of different properties by each Sasang Constitution. But SCM theory has concentrate to explaining different symptoms that distinguish health condition, not much concerned with practical methods like face features, pulse diagnosis, skin surface properties and voice features. Physical properties of practical diagnosis methods from literature finding have been researched. As a result, complexion and face moisture were described to be physical properties related to health State. In scope of pulse diagnosis, depth, rate, contour, width and pressure are related. Skin surfaces' elasticity, moisture, fraction properties were also suggested as factors of health State of Sasang Constitution. We assume that this study would contribute further studies for objectifying and quantifying diagnosis methods to evaluate health state grades of Sasang Constitution.

The subjects consisted of 145 females of various ages who visited skin care room in cerming health promoting behaviors(Park In sook's Profile) and questions on their behavioral practices pertaining to personal skin care were used. The investigation also ess of the four parts of the epidermal facial tissue studied. All data collected wee entered into the SAS program and analyzed for frequency, percentages, the utilized Pusan. The study dates ranged from May 1, 1998 to May 30, 1998. The methods used for this investigation were a questionnaire survey consisting of general objective questions. The questions con a "skin analyzer" to measured levels of moisturizing hydrated, facial oils, and roughnmean, t-test, ANOVA, and Pearson Correlation Coefficients. The results of this study were as follows ; 1. Epidermal facial oil was at its highest levels in the chin area with additional decreasing levels in the forehead and nose regions. The least regions were those of the cheeks. The highest levels of hydration on the other hand started with the forehead followed by the area of the chin, the cheeks and the lowest level of epidermal facial hydration was in the region of the nose. 2. The average score of the performance in the health promoting behaviors variable was 139.51. The variables with the highest degree of the performance were rest and sleeping(35.71). The lowest degree was hiegenic life(23.44). 3. The relationship health promoting behaviors and epidermal condition was not correlated with oil, hydration and roughness of the skin surface. 4. Skin care behavioral characteristics related to epidermal condition were washing style and temperature of washing water. 5. General characteristics related to epidermal condition were occupation, education level, acne and melasma. In conclusion, this study showed that several factors were significant in the behavior of skin care. Clear knowledge of both internal and external factors which affect the epidermal condition will help women to pursue active and appropriate practices in their health behaviors and skin care.

The aim of this study was to evaluate the safety and effects of a soy lecithin-based supplement on the general health, skin condition, and blood lipid levels of dogs. Twenty-five, healthy, privately-owned dogs were enrolled in the study. Oral supplementation was administered for 8 weeks in the treatment group. Evaluation items included a thorough physical examination, owner responses to a questionnaire, blood analysis (CBC, CRP, serum chemistry, lipid profile). The results showed a significant improvement in amount of exercise, water intake, skin exfoliation in the treatment group (P < 0.05) but no significant changes in the other evaluation items, including no significant changes in blood component results following administration of the supplement. Most dogs well tolerated the treatment, and there were no serious adverse events. We suggest that soy lecithin has potential as a nutraceutical for the positive effect of general health condition such as activity and skin condition. Further studies are needed to establish the appropriate dose level and administration frequency of soy lecithin in dogs.

Background: Though people of color (POC) are less likely to become afflicted with skin cancer, they are much more likely to die from it due to delay in detection or presentation. Very often, skin cancer is diagnosed at a more advanced stage in POC, making treatment difficult.The purpose of this research was to improve awareness regarding skin cancers in people of color by providing recommendations to clinicians and the general public for early detection and photo protection preventive measures. Methods: Data on different types of skin cancers were presented to POC. Due to limited research, there are few resources providing insights for evaluating darkly pigmented lesions in POC. Diagnostic features for different types of skin cancers were recorded and various possible risk factors were considered. Results: This study provided directions for the prevention and early detection of skin cancer in POC based on a comprehensive review of available data. Conclusions: The increased morbidity and mortality rate associated with skin cancer in POC is due to lack of awareness, diagnosis at a more advanced stage and socioeconomic barriers hindering access to care. Raising public health concerns for skin cancer prevention strategies for all people, regardless of ethnic background and socioeconomic status, is the key to timely diagnosis and treatment.
