Background: Ginseng (Panax ginseng Meyer) is a well-characterized medicinal herb listed in the classic oriental herbal dictionary as "Shin-nong-bon-cho-kyung." Ginseng has diverse pharmacologic and therapeutic properties. Black ginseng (BG, Ginseng Radix nigra) is produced by repeatedly steaming fresh ginseng nine times. Studies of BG have shown that prolonged heat treatment enhances the antioxidant activity with increased radical scavenging activity. Several recent studies have showed the effects of BG on increased lipid profiles in mice. In this study report the effects of water and ethanol extracts of BG on hypercholesterolemia in rats. To our knowledge, this is the first time such an effect has been reported. Methods: Experiments were conducted on male Sprague Dawley rats fed with a high-cholesterol diet supplemented with the water and ethanol extracts of BG (200 mg/kg). Their blood cholesterol levels, serum white blood cell levels, and cholesterol-metabolizing marker genes messenger RNA (mRNA) expression were determined. Liver and adipose tissues were histologically analyzed. Results: We found that BG extracts efficiently reduced the total serum cholesterol levels, low-density lipoprotein (LDL) levels with increased food efficiency ratio and increased number of neutrophil cells. It also attenuated the key genes responsible for lipogenesis, that is, acetyl-coenzyme A (CoA) acetyltransferase 2, 3-hydroxy-3-methyl-glutaryl-CoA reductase, and sterol regulatory element-binding protein 2, at the mRNA level inside liver cells. Furthermore, the BG extract also reduced the accumulation of fat in adipose tissues, and inhibited the neutral fat content in liver cells stained with hematoxylin and eosin and oil red O. Conclusion: Administration of BG extracts to Sprague Dawley rats fed with high-cholesterol diet ameliorated hypercholesterolemia, which was mediated via modulation of cholesterol-metabolizing marker genes. This data throw a light on BG's cardioprotective effects.

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.

This study selected emergency medical technicians at 24 fire police boxes in Jeonnam in order to examine the relationship between job stress, fatigue and job satisfaction of 119 emergency medical technicians. Data were collected from Apr. 10 to May 9, 2004, questionnaires were mailed and returned by mail. Total 109 questionnaires were distributed and 89 questionnaires were collected and 80 except 9 omitting answers and showing inappropriate answers were used for final analysis. The results of this study are as follows. A. The total mean of areas composing job stress in the degree of job stress of 119 emergency medical technicians was over the average as 2.54 (SD .44) of 4 full marks. According to the degree of job stress by each area, the highest area of job stress was crisis situation (2.98), followed by role conflict as professional job (2.58), social factors (2.57), involvement in organization (2.55). To the contrary, the areas of the lowest job stress were professional knowledge and technique (2.35), psychological burden of medical limitation (2.38), conflicts in personal relationship and services (2.45) and improper treatment (2.53). B. The degree of fatigue of 119 emergency medical technicians by areas was over mean as 2.09(SD .49) of 4 full scores and physical fatigue was highest (2.18), followed by mental fatigue (2.11) and neurosensory fatigue (1.99). C. The degree of job satisfaction of 119 emergency medical technicians was 2.71 of 5 full scores and working condition area (3.70) showed the highest job satisfaction, followed by requirement of organization (2.85) and the lowest job satisfaction area was job itself (2.18), followed by desire for job (2.49). D. According to differences in demographical characteristics of 119 emergency medical technicians, there was no variable of statistical difference at job stress and job satisfaction in significance level .05, but fatigue showed statistical difference at final education (F=2.393, p=.046). E. According to differences related to job characteristics of 119 emergency medical technicians, job stress showed statistical differences at motif of current services (F=4.935, p=.003), fatigue showed those at health conditions (F=2.732, p=.008), job satisfaction at overtime (F=3.038, p.034) and the greatest reason of having job (F=3.217, p=.017), F. As a result of analyzing correlations between job stress. fatigue and job satisfaction of the subject, job stress showed positive correlations (r=.411, p=.000) with fatigue and negative correlation (r=-.267, p=.008) with job satisfaction. Fatigue showed negative correlation (r=-.287, p=.005) with job satisfaction. Therefore, the hypothesis of this study. "There will be relationship between degree of stress, fatigue and job satisfaction of subjects." was supported.

Background: The global burden of cancer is continuously increasing. According to recent report of the National Cancer Registry Programme (NCRP) on time trends it is estimated that future burden of cancer cases for India in 2020 will be 1,320,928. It is well known that knowledge of the incidence of cancer is a fundamental requirement of rational planning and monitoring of cancer control programs. It would help health planners to formulate public health policy if relevant ethnic groups were considered. North East-India alone contains over 160 Scheduled Tribes and 400 other sub-tribal communities and groups, whose cancer incidence rates are high compared to mainland India. As since no previous study was done focusing on ethnicity, the present investigation was performed. Materials and Methods: In this paper PBCR-Guwahati data on all cancer registrations from January 2009 to December 2011 for residents of the Kamrup Urban District, comprising an area of 261.8 sq. km with a total population of 900,518, including individual records with information on sex, age, ethnicity and cancer site are provided. Descriptive statistics including age adjusted rates (AARs) were taken as provided by NCRP. For comparison of proportional incidence ratios (PIR) the Student's t test was used, with p<0.05 considered as statistically significant. Results and Conclusions: Differences in leading sites of Kamrup Urban District since from the beginning of the PBCR-Guwahati were revealed among different ethnic groups by this study. The results should help policy makers to formulate different strategies to control the level of burden as well as for treatment planning. This study also suggests that age is an important factor of cancer among different ethnic populations as well as for overall population of Kamrup District of Assam.

As a nursing practice involves nurses'actions in a specific context of health care, this study has focused on exploring the espoused theories in nursing practice within the action science perspectives. Espoused theories are the belief, principles, and rationale expressed by the practitioner as guiding her/his actions in a situation of practice. The data were analysed qualitatively and 25 elements of espoused theories of nursing action were identified and clustered into 6 categories. The 25 elements of espoused theories are as follows: The clinical nurse worked in wholistic and individual nursing, focussed on the patient's needed, comfort and supportive nursing (5 theories of nursing goal); excellent skills, knowledge based, assessment and data collection, explaining, educating or a scientific basis(6 theories of nursing intervention): advocacy, value oriented, treatment, accountability and commitment(4 theories of nursing ethics); human respect, partnership, trust(3 theories of patient-nurse relationship) : knowledgable, accumulated clinical experiences and personally lived experiences, positive perspectives(4 theories of nurse), role of intervention, rewarding, peer relationship(3 theories of situations). The above mentioned espoused theories are similar to that of nursing textbooks which students learned through basic nursing education and almost the same as the Acts ofa Nurse in Korean. However, we are doubtful whether nurses actually do as they think. Therefore, it is recommended to review the theories-in-use in order to find any discrepancies between the espoused theories and the reality of nursing actions.

Background: Nodal invasion by colorectal cancer is a critical determinant in estimating patient survival and in choosing appropriate preoperative treatment. The present meta-analysis was designed to evaluate the diagnostic value of endorectal ultrasound (EUS) in preoperative assessment of lymph node involvement in colorectal cancer. Materials and Methods: We systematically searched PubMed, Web of Science, Embase, and China National Knowledge Infrastructure (CNKI) databases for relevant studies published on or before December 10th, 2014. The sensitivity, specificity, likelihood ratios, diagnostic odds ratio (DOR) and area under the summary receiver operating characteristics curve (AUC) were assessed to estimate the diagnostic value of EUS. Subgroup analysis and meta-regression were performed to explore heterogeneity across studies. Results: Thirty-three studies covering 3,016 subjects were included. The pooled sensitivity and specificity were 0.69 (95%CI: 0.63-0.75) and 0.77 (95%CI: 0.73-0.82), respectively. The positive and negative likelihood ratios were 3.09 (95%CI: 2.52-3.78) and 0.39 (95%CI: 0.32-0.48), respectively. The DOR was 7.84 (95%CI: 5.56-11.08), and AUC was 0.80 (95%CI: 0.77-0.84). Conclusions: This meta-analysis indicated that EUS has moderate diagnostic value in preoperative assessment of lymph node involvement in colorectal cancer. Further refinements in technology and diagnostic criteria are necessary to improve the diagnostic accuracy of EUS.

X-linked agammaglobulinemia (XLA) is a hereditary humoral immunodeficiency that results from Bruton's tyrosine kinase (BTK ) gene mutations. These mutations cause defects in B-cell development, resulting in the virtual absence of these lymphocytes from the peripheral circulation. Consequently, this absence leads to a profound deficiency of lg all isotypes, and an increased susceptibility to encapsulated bacterial infections. A 15-month-old Korean boy presented with recurrent sinusitis and otitis media after 6 months of age, and had a family history of 2 maternal uncles with XLA. Laboratory tests revealed a profound deficiency of Ig isotypes, and a decreased count of $CD19^+$ B cells in the peripheral circulation. Based on his family history and our laboratory test results, he was diagnosed with XLA. We performed BTK gene analysis of peripheral blood samples obtained from family members to confirm the diagnosis. Mutational analysis revealed a novel hemizygous frameshift mutation (c.82delC, p.Arg28Alafs*5), in the BTK gene. His mother and maternal grandmother were heterozygous carriers of this mutation and his two maternal uncles were hemizygous at the same position. After XLA diagnosis, intravenous immunoglobulin (400 mg/kg, monthly) treatment was initiated; recurrent sinusitis and otitis media were subsequently brought under control. To our knowledge, this is the first reported case of a Korean pedigree with a novel mutation in the BTK gene.
