Purpose: It is generally believed that alopecia is caused by various factors such as scars, stress, genetical factors, androgens, etc. Androgenic alopecia is one of the most common cause of alopecia and found mainly in males. Propecia (Merck & Co., USA) and Minoxidil (McNEIL-PPC, Inc, USA) were the drugs approved from FDA for treatment of androgenic alopecia. Surgical treatments such as flap, tissue expansion, scalp reduction and hair transplantation can be considered if necessary. Hair micrograft techniques were developed for natural hair shapes and minimal adverse effect. There were attempts to measure the length of the forehead of the Korean young adults. However attempts to classify the shape and location of forehead hairline were rare. This study attempted to find out standard hairlines of young adults in their 20s & 30s and the result would be the guideline of the hairline in hair replacement surgery of male patients in their 40s & 50s. Methods: 200 male adults in 20s and 30s were photographed and measured the length of 11 vertical index lines to determine hairline. The indexes are the distances from hairline to intercanthal midpoint (A), to medial canthus (B), to upper eyelid fissure (C), to lower eyelid fissure (D), to lateral canthus (E) and distance from lateral highest point to medial lowest point, if the hairline is M-shape (F). Additionally, we classified the hairlines into 4 groups, M, horizontal, inverted U and irregular shapes. Results: The most common hairline of male adults in their 20s is inverted U-shape (53.3%), followed by horizontal-shape, M-shape, irregular-shape. In their 30s, inverted U-shape (59%) is followed by irregular-shape, M-shape, horizontal-shape. The M-shape is more frequently found in males in 30s than those in 20s. The mean values of the indexes in their 20s are as follows: A (76.14 mm), B (Rt: 75.78 mm, Lt:76.41 mm), C (Rt: 69.43 mm, Lt: 69.92 mm), D (Rt: 76.92 mm, Lt:77.46 mm), E (Rt: 64.16 mm, Lt: 64.73 mm), F (4.09 mm). Those in their 30s are as follows: A (76.13 mm), B (Rt: 76.114 mm, Lt: 76.02 mm), C (Rt: 69.87 mm, Lt: 70.37 mm), D (Rt: 77.37 mm, Lt: 77.58 mm), E (Rt: 69.63 mm, Lt: 69.85 mm), F (6.14 mm). Conclusion: The knowledge about human body measurement is indispensable to plastic surgeons. In this study, inverted U shape is the most common type of hairline in 30s, and similar distribution is found in 20s. The percentage of M shape in their 30s is elevated more than 10% compared to that in their 20s. The study of hairline shapes and 11 indexes of hairlines can be useful for planning of the hair transplantation and postoperative evaluation. This study being based on photogrammetry, there may be differences between actual distance of curved face and projected distance on flat photographs.

Human hair is an excretory system for trace metals and thus metal content in human hair can reflect the body status. The investigation of trace elements in human hair has been correlated with the diagnosis of various diseases as well as the monitoring of deficiency statues in nutrition. Many chronic diseases may be related to mineral status, some may be related to toxic mineral. Hair samples were collected from 120 inhabitants of the city of Seoul, Korea. In this study the concentrations of 10 elements (Hg, Pb, Cd, Al, As, U, Bi, Sb, Ba, Be) in hair were determined by inductively coupled plasma mass spectroscopy (ICP-MS). The conclusions showed that people in Seoul, Korea were affected by some kinds of toxic minerals. The Hg concentrations of male are higher than those of female and reference range. The mean concentration of Sb was higher in the female than male and reference range. In age distribution, the mean concentration of Hg was in 40's are higher than 20's and 30's and reference range. The concentrations of Al were the highest in the 20's. After analyzing, we concluded that a compounded treatment should be conducted, which considers the variety of factors related to detoxification.

Treatments for alopecia areata include topical corticosteroid treatment, corticosteroid intralesional injection, systemic corticosteroid treatment, PUVA(psoralen-UVA) and topical immunotherapy. The therapeutic effects are variable. Alopecia totalis is hard to treat completely. Topical immunotherapy with dinitrochlorobenzene (DNCB), squaric acid dibutyl ester (SADBE) or diphenylcyclopropenone (diphencyprone, DPCP) represents the most accepted therapeutic modality for the treatment of extensive alopecia areata. We report two cases of alopecia totalis treated with DPCP. After DPCP treatment, total scalp hair was completely recovered.

Homozygous mutations in NUDT15 R139C are known as the major factor associated with thiopurine-induced early leukopenia, particularly in Asian patients. Therefore, NUDT15 genotyping is currently recommended before thiopurine treatment to identify patients who are NUDT15 poor metabolizers and consider the use of an alternative immunomodulatory therapy. We report a case of a 12-year-old Korean girl with Crohn's disease (CD), in whom thiopurine-induced leukopenia was prevented by initiation of azathioprine (AZA) therapy at a low dose (0.5 mg/kg/day) and early detection of significant hair loss and white blood cell (WBC) count decrease at 17 days from the start of AZA treatment. The WBC count dropped from 8,970/μL to 3,370/μL in 2 weeks, and AZA treatment was stopped because of concerns of potential leukopenia in the near future. Her WBC count recovered to 5,120/μL after 3 weeks. Gene analysis later revealed that she had a homozygous mutation in NUDT15 R139C, resulting in a poor metabolizing activity of NUDT15. In situations when NUDT15 genotyping is unavailable, initiation of AZA therapy at 0.5 mg/kg/day with close observation of hair loss and WBC counts within 2 weeks may be an alternative way to prevent thiopurine-induced early leukopenia in Asian children with CD.

Cordyceps has a reputation for its broad biological activities and as a tonic which replenishs vital function in Chinese traditional medicines. As an attempt to obtain fundamental data for the development of new type Cordyceps, the effects of the fruiting bodies of cultivated fungus of Paecilomyces japonica grown on silkworm larvae on radiationinduced damages were investigated. We performed this study to determine the effect of Dongchongxiacao (Paecilomyces japonica) on jejunal crypt survival, endogenous spleen colony formation, and apoptosis in jejunal crypt cells and hair follicles of mice irradiated with high and low dose of gamma-radiation. Treatment with Dongchongxiacao showed no significant modifying effects on the jejunal crypt survival and endogenous spleen colony formation. The frequency of radiationinduced apoptosis was reduced by pretreatment of Dongchongxiacao (i.p.: 50 mg/kg of body weight, at 12 and 36 hours before irradiation, p<0.01). The spontaneous levels of apoptotic cells are $0.082{\pm}0.041$ in intestinal crypts and $0.231{\pm}0.084$ per hair follicle section of skin. Pretreatment of Dongchongxiacao was associated with decreases of 26.86% in intestinal crypt and 66.36% in hair follicle decrease in the number of cells with nuclei positively stained for apoptosis compared with the irradiation control group. We demonstrated for the first time that Dongchongxiacao administration could reduce the extent of apoptosis produced by radiation in the hair follicle. The results presented herein that Dongchongxiacao given before irradiation is capable of reducing the severity of cell loss as a result of apoptosis.

In this study, the characteristics of various raw hairs used for traditional Korean brushes were examined; further, the characteristics and deterioration patterns of Korean, Chinese, and Japanese brushes were compared, with a quantitative evaluation to assess the brush performance. The tensile strength was generally found to be higher with a greater fiber thickness. Among the hairs examined, the back and flank hair of goat was more damaged than that in other parts, and the tensile strength was low. Higher elasticity of the brush made with hair of high cysteine content was measured. Owing to deterioration by use of the brushes, artificial drying brushes had a higher yellowness index and lower tensile strength than natural drying brushes. Further, it was confirmed that brushes with good absorbency exhibited good consistency, but not good elasticity. Thus, the performance of the brush can be influenced by the kind of material used and the brush usage pattern. In addition, it is possible to identify the material science characteristics of brushes which have been produced only by experience; therefore, the results of this study could provide basic data for manufacturing brushes employed in conservation treatment, in the future.

This study was carried out to develop a method for decreasing the heavy metal composition of living stock. Sprague-Dawley (SD) male rats were pre-treated with heavy metals administered i.p. at the limits of regulation according to the feed CODEX in Korea. Herbal medicine remnant was administered p.o. (2, 4 ppm of average feeding amount) for the entire period of study with organic selenium (2 ppm of average feeding amount) before any other treatment. 2,2'-azobis(2-amidinopropane) dihydrochloride (AAPH) was also administered i.p. in a single dose of 60 mg/kg body weight before animals were sacrificed. The TBARS test with the FOX assay demonstrates a decrease of heavy metals due to these functional materials in vitro. Moreover, this decrease in heavy metals was also demonstrated by in vivo tests based on SD rats hair analysis and organ analysis after 6 weeks. A good linear correlation between hair analysis and organ analysis represented by liver and blood was shown. The present findings suggest that measurement method of heavy metal composition using hair analysis for healthy livestock can be used in place of detection methods carried out by organ and blood analysis, and herbal medicines with organic selenium may be very effective at decreasing heavy metals of feed materials in feed manufacture industry.

Objectives : The purpose of this study is to report the causes and the effects of korean medicine treatment on alopecia. Methods : 1050 patients with alopecia, who had visited oriental medical clinics from July 2011 to October 2012, were analyzed by self-assessments. And 153 patients of them were treated with korean medicine treatment for 3 months. Treatment results were evaluated by patients' self-assessments and global & enlarged photographic reviews. Results : 1. The gender ratio of male to female was 2:1 and most patients belonged to the 20~30 year old group. 2. Family history of baldness in alopecia patients was a total of 57.3%, paternal 44.4% and maternal 21.2%. 3. Subjective symptoms of fever in parietal region was a total of 97.4% in alopecia patients. 4. After 1 month treatment, the fever in the parietal region was decreased by 37.3% of patients. And their subjective hair loss was also significantly decreased. 5. After 3 months of treatment, the global photographic review was improved by 56.2% of the patients and the enlarged photographic review was significantly improved by 5.2% in patients' total hair count. Conclusions : A significant number of alopecia patients were young and less relative in genetic alopecia causes was less relevant than the past. Recent causes of alopecia were more concerned with the fever in parietal region. According to that reason, cooling effect korean medicine treatment was expected to be effective for febrile alopecia, and actually had significant effects on this study. For future studies, it's long term treatment and follow up studies are needed.

Effect of red ginseng treatment on experimentally induced hyperkeratosis was investigated by light microscopic observation scanning electron microxcope (SEM) examination, epidermal enzyme activities nd lipid contents. Both light microscopic observation and SEM examination showed that hexadecane induced epidermal hyperplasia, hypertrophy and hyperkeratosis by increasing the numbers as well as the sizes of epidermal cells including desquamating horny cells. The superficial horny cells were protruded around the base of hair shaft. Among red ginseng components, only saponin treatment inhibited epidermal hyperplasia and hyperkeratosis by reducing the thickness of epidermis and arranging the cornified cells. Saponin from korean red ginseng inhibited abnormally increased epidermal LDH, ICD and G6PDH activities and reduced the contents of epidermal lipids induced by hexadecane. It seems that red ginseng saponin has preventive effect on experimental hyperkeratosis possibly by controlling the enzyme activities involved in epidermal cellular metabolism, resulting in reduced amounts of abnormal epidermal lipids.

Trichotillomania is a neuropsychiatric disorder characterized by repetitive pulling out of one's hair. We present a trichotillomania case study illustrating the effectiveness of habit reversal training, which has recently been found, in western countries, to be a very effective cognitive behavioral treatment. The refractory patient in our study had previously received 1 year of drug treatment and psychiatric consultation for the disorder. We administered 10 habit reversal training sessions, which was followed by an obvious improvement in the patient's trichotillomania symptoms. Our observations indicate that habit reversal training might be effective in the treatment of trichotillomania.
