  • Objective: Yikgeebohyul-tang (Yiqib$\check{u}$xu$\grave{e}$-t$\bar{a}$ng) is one of the representative prescriptions for invigoration of vitality and nourishing of the blood. This study was carried out to investigate the effects of Yikgeebohyul-tang (Yiqib$\check{u}$xu$\grave{e}$-t$\bar{a}$ng) on hair regrowth and cytokine changes in a shaving model of C57BL6 mice. Method: Five-week-old mice were acclimated for 1 week at a temperature between $21-23^{\circ}C{\acute{E}}$, 40-60% relative humidity, and 12h of a light/dark cycle before beginning of the experiment. There were two groups including normal saline (control) and a positive control of oral intake of Yikgeebohyul-tang (Yiqib$\check{u}$xu$\grave{e}$-t$\bar{a}$ng) extract (sample) in 18 female mice. The test compounds were topically treated once a day over 14 days. The hair regrowth was photographically and histologically determined during the experimental period of 14 days. Revelation of TGF-${\beta}1$ and EGF were also determined using immunohistochemistry. In addition to that, IFN-$\gamma$, IL-4 and IL-10 were determined in serum. Results: Hair regrowth in the sample group was promoted earlier and faster than the control group, as shown by concentrations of hairs and thick-hair ratio in the sample group. TGF-${\beta}1$ was not revealed in either control or sample group. EGF was strongly positive in out root sheath of some thick hair of the sample group. Serum IFN-$\gamma$ was significantly decreased in the sample group compared with the control group at 7 experimental days. However, it was not significantly decreased at 14 experimental days. Serum IL-4 was significantly increased in the sample group compared with the control group at 7 experimental days. However, it was not significantly decreased at 14 experimental days. Serum IL-10 was decreased in the sample group compared with the control group, but with no real statistical significance. Conclusion: These results suggest that Yikgeebohyul-tang (Yiqib$\check{u}$xu$\grave{e}$-t$\bar{a}$ng) has hair growth promoting activity and it can be used for treatment of alopecia. Also, these effects relate to EGF revelation of hair roots, a decrease in serum IFN-$\gamma$, and an increase of serum IL-4.

  • 일반계 비만고교생 60명을 4그룹으로 구분, 웨이트트레이닝을 1일 60${\sim}$70분, 주 3회, 8주간 강도별(A group: control group, B group: $40{\sim}55%RM$, C group: $60{\sim}75%RM$, D group: $80{\sim}90%RM$)로 실시하여 대사증후군 5가지 인자(waist size, fasting glucose, TG, HDL-C, blood pressure) 개선을 위한 가장 효과적인 WT 강도를 알아보았다. Waist size의 감소는 운동군 모두 효과적이었으나 $40{\sim}55%RM$$60{\sim}75%RM$ 실시 그룹이 더욱 효과적이었고, TG의 감소도 운동군 모두 효과적이었으나 $40{\sim}55%RM$ RM 실시 그룹이 더욱 효과적이었다. Fasting glucose는 차이가 없었으며, HDL-C는 대조군보다 $80{\sim}90%RM$ 실시 그룹이 유의하게 증가하였고, blood pressure는 diastolic blood pressure는 차이가 없었고, systolic blood pressure는 다른 그룹보다 $40{\sim}55%RM$ 실시 그룹이 유의하게 감소하였다. 이러한 결과는 중 고강도보다는 오히려 저강도가 대사증후군 인자 개선에 효과적이라는 것을 시사하며, 웨이트트레이닝이 비만고교생의 대사증후군 위험 인자를 개선해준다는 사실을 확인하였다. 따라서, 비만고교생은 대사증후군 인자의 개선을 위해 $40{\sim}55%\;RM$의 웨이트트레이닝을 실시하는 것이 효과적이라 생각된다.

  • Purpose: This study is to identify the effect of Ankle Joint Taping applied to patients with chronic hemiplegia on their gait velocity and joint angles. Methods: We randomly extracted a clinical sample from 30 patients with hemiplegia resulting from stroke and classified them into two groups of a control group including 15 patients offered a regular therapeutic exercise and a test group including 15 patients offered taping. We also conducted the comparative analysis and pretest of the affected ankle joint angles by the normal characteristics of all subjects, Time to up and go test (TUG), 3D movement analyzer before the intervention. We applied taping to a test group for eight hours a day, five days a week during two weeks and conducted the comparative analysis of the gait velocity and the affected ankle joint angles by a comparison between and within two groups of before and after the intervention by conducting a posttest after the intervention. The result is as followings. Results: It indicated that there was a significantly decreased time with the increased gait velocity that a test according to a result of comparing the gait velocity within two groups (p<0.05). It indicated that there was a significantly increased angle in a comparison within two groups of test that inversion angle of a control group according to a result of comparing the ankle joint angles by 3D movement analyzer within groups (p<0.05). Conclusion: We found that TUG will help patients walk independently because it met a test group's need in the change of the gait velocity between two groups by recording less than 14 seconds which is the standard of using assistive aids and also found that ankle joint taping will help the joints prevent their function change considering that a control group showed an increased inversion angle in the change of the ankle joint within two groups.

  • One hundred and sixty crossbred pigs ($6.62{\pm}0.36kg$) weaned at day $18{\pm}1$ were used to investigate the effects of lactitol and tributyrin on performance, small intestinal morphology and enzyme activity. The pigs were assigned to one of five dietary groups (4 pens/diet with 8 pigs/pen) and were fed the negative control diet or the negative control diet supplemented with 10 g/kg glutamine (as a positive control), or 3 g/kg lactitol (${\beta}$-D-galactopyranosyl-($1{\rightarrow}4$)-D-sorbitol), or 5 g/kg tributyrin (butanoic acid 1,2,3-propanetriyl ester), or 3 g/kg lactitol+5 g/kg tributyrin. Body weight and feed intake were measured weekly during the 4-week study. On day 7, four pigs per dietary treatment were sacrificed to examine small intestinal morphology and enzyme activity. The results showed that: (1) Compared with the negative control diet, the positive control diet improved weight gain and feed efficiency during weeks 1-2 and over the entire study (p<0.05), and also decreased duodenal and ileal crypt depth (p<0.05), but did not alter intestinal enzyme activity (p>0.05). Lactitol improved feed efficiency during weeks 3-4 and over the entire study (p<0.05), but did not improve weight gain and feed intake, intestinal morphology or enzyme activity (p>0.05). Tributyrin improved weight gain and reduced feed/gain during weeks 3-4 and over the entire study. Tributyrin significantly decreased crypt depth in the duodenum and ileum, and increased duodenal lactase and ileal maltase activity (p<0.05). Lactitol+tributyrin increased weight gain during weeks 3-4 and over the entire study, and improved feed efficiency during weeks 1-2 and 3-4 and over the entire study (p<0.05). Lactitol+tributyrin increased the jejunal villus height, and decreased the duodenal and ileal crypt depth (p<0.05). Lactitol+tributyrin also increased jejunal lactase and sucrase activity (p<0.05). (2) Compared with the positive control, tributyrin improved weight gain and reduced feed/gain during weeks 3-4 (p<0.05), decreased the ileal crypt depth, and improved the duodenal lactase and sucrase activity (p<0.05). Lactitol+ tributyrin improved weight gain during weeks 3-4, improved feed efficiency during weeks 3-4 and over the entire study, increased the ileal villus height, and increased jejunal lactase, sucrase and maltase activity (p<0.05). These results showed that tributyrin improved performance, intestinal morphology and enzyme activity, while the effect of lactitol was very limited. These results also showed that, compared with glutamine, tributyrin was more effective in improving intestinal morphology and enzyme activity, and tributyrin exerted a superior effect in improving performance as weaning progressed. These observations suggest that, as a chemical for repairing intestinal atrophy, glutamine and tributyrin should be used in the first and second periods of the starter phase, respectively.

  • BACKGROUND/OBJECTIVES: This is the first study to identify common genetic factors associated with the basal metabolic rate (BMR) and body mass index (BMI) in obese Korean women including overweight. This will be a basic study for future research of obese gene-BMR interaction. SUBJECTS/METHODS: The experimental design was 2 by 2 with variables of BMR and BMI. A genome-wide association study (GWAS) of single nucleotide polymorphisms (SNPs) was conducted in the overweight and obesity (BMI > $23kg/m^2$) compared to the normality, and in women with low BMR (< 1426.3 kcal/day) compared to high BMR. A total of 140 SNPs reached formal genome-wide statistical significance in this study (P < $1{\times}10^{-4}$). Surveys to estimate energy intake using 24-h recall method for three days and questionnaires for family history, a medical examination, and physical activities were conducted. RESULTS: We found that two NRG3 gene SNPs in the 10q23.1 chromosomal region were highly associated with BMR (rs10786764; $P=8.0{\times}10^{-7}$, rs1040675; $2.3{\times}10^{-6}$) and BMI (rs10786764; $P=2.5{\times}10^{-5}$, rs10786764; $6.57{\times}10^{-5}$). The other genes related to BMI (HSD52, TMA16, MARCH1, NRG1, NRXN3, and STK4) yielded P < $10{\times}10^{-4}$. Five new loci associated with BMR and BMI, including NRG3, OR8U8, BCL2L2-PABPN1, PABPN1, and SLC22A17 were identified in obese Korean women (P < $1{\times}10^{-4}$). In the questionnaire investigation, significant differences were found in the number of starvation periods per week, family history of stomach cancer, coffee intake, and trial of weight control in each group. CONCLUSION: We discovered several common BMR- and BMI-related genes using GWAS. Although most of these newly established loci were not previously associated with obesity, they may provide new insights into body weight regulation. Our findings of five common genes associated with BMR and BMI in Koreans will serve as a reference for replication and validation of future studies on the metabolic rate.

  • 본 연구는 L-arginine 섭취가 고강도 훈련 프로그램에 따른 카누선수의 근 손상 지표, 피로 물질 및 경기력 향상에 미치는 영향을 확인하는데 목적이 있다. 이를 위해 고등학교 카누 선수 7명을 대상으로 고강도 훈련 프로그램을 적용하였으며, 고강도 훈련 프로그램은 주 2회의 유산소 운동(화, 목), 주 3회의 무산소 운동(월, 수, 금) 그리고 주 5회의 유연성 운동을 실시하였다. 고강도 훈련 프로그램을 진행하는 6주 과정 중에 처음 2주는 약물섭취(L-arginine or 위약)를 실시하고 다음 2주는 wash out, 그리고 마지막 2주도 약물섭취(L-arginine or 위약)를 실시하였다. 모든 연구대상자들이 L-arginine 섭취(시험군)와 위약그룹(대조군)으로 배정되는 교차설계로 디자인하였다. L-arginine은 하루 총 3g으로 섭취하였다. 채혈을 통해 L-arginine 섭취에 따른 근 손상 지표, 피로 지표, 항산화력을 확인하였으며, 혈관내피세포기능 분석을 위해 FMD, 그리고 카누 에르고미터를 활용하여 카누 경기력을 분석하였다. 본 연구결과 L-arginine 섭취에 따른 Ammonia, IP, CK의 수준의 직접적인 효과는 나타나지 않았으며, LDH의 수준은 L-arginine 섭취로 인해 PLA 그룹보다 ARG 그룹에서 더 감소하는 것으로 나타났다. L-arginine 섭취에 따른 Total NO, d-ROMs, BAP, 그리고 FMD의 수준도 통계적으로 유의한 차이는 없는 것으로 나타났다. 마지막으로 카누 경기력 향상을 확인하기 위해 실시한 500M 카누 에르고미터 결과에서 총시간, 스트록 거리, 평균속도 분석에서 L-arginine의 운동수행능력 향상의 직접적인 효과는 나타나지 않았다. 하지만 L-arginine 섭취로 인해 근 손상 지표, 피로 지표, 항산화력, FMD, 그리고 카누 경기력 수준이 개선되는 경향은 나타났다. 따라서 L-arginine 섭취의 잠재적인 운동능력 향상 보조제 효과에 대한 추가적인 연구가 필요할 것으로 생각된다.
