Objectives : Radix Angelicae Gigantis(RAG) and Resina Ferulae(RF) have been used in oriental medicine or folk medicine to increase stamina. The aim of this study was the characterization of the mechanism of action of RAG and RF on smooth muscle and macrophages in rats to find new substances for the treatment of erectile dysfunction, cardiovascular diseases and immune dysfunction. Methods : We investigated the effects of the water extracts of RAG and RF on phenylephrine or KCl-contracted rat endothelium-denuded aorta, the production of NO in vascular smooth muscle cell (VSMC) and the production of NO and induction of iNOS in the $IFN-{\gamma}-primed$ RAW 264.7 cells. Results : The water extracts of the RAG and RF showed significant concentration-dependent relaxation effects on phenylephrine or KCl-contracted rat endothelium-denuded aorta. It also reduced the tension of the rat endothelium denuded aorta which was contracted in $Ca^{2+}-free$ media. On the other hand, it increased production of NO in VSMC which was stimulated with $IL-{\beta}$ or $IL-{\beta}$ plus $IFN-{\gamma}$. The water extracts of RAG and RF increased production of NO and induction of iNOS in the $IFN-{\gamma}-primed$ RAW 264.7 cells. Conclusions : According to the above results, the water extracts of RAG and RF relaxed the smooth muscle effectively and increased the production of NO in VSMC and macrophages. So, these herbs can be applied to erectile dysfunction, hypertension, angina pectoris, artherosclerosis and a defense defect for virus or microbe.

KJHST (Kejihongsarntang) is a modified oriental prescription that consists of five herbs such as Ginseng Radix rubra Koreana, Atractylodis Rhizoma, Zingiberis Rhiaoma, Cinnamomi Ramulus and Glycyrrhizae Radix. For the evaluation of antioxidant and staminal activities of KJHST (Kejihongsarntang), the study was done in comparison of Ginseng Radix rubra (GR). For the antioxidant study, KJHST inhibited hemolysis of erythrocyte and decolored the DPPH(2,2-diphenyl-1-picrylhydrazyl) free radical in a dose depenrlent manner more effectively than GR alone in vitro. KJHST and GR significantly suppressed the time course (1 hr∼6 hr)-level of MDA (malondialdehyde) following AAPH (2,2'-azo-bis-(2-amidino-propane) dihydrochloride) treatment in vivo as compared with control data with no statistical difference. From the evaluation of stamina by swimming test GR and KJHST significantly increased the swimming time in a time and dose dependent manner as compared with control data, while GR was more effective than KJHST in 2 weeks after treatment, though KJHST was more effective than GR at low dose (25 m/kg) 4 weeks after treatment. From the results it can be concluded GR and KJHST had antioxidant and staminal activities.

Yaksun, a medicinal diet, has been traditionally prepared and applied (based on theories in oriental medicine) for the modulation of disease symptoms and signs. However, restaurants that serve and claim Yaksun mainly focus on stamina foods. A consistent definition of Yaksun has not been provided, which can confuse the public interpretation of Yaksun. The purpose of this study was to investigate the perception of Yaksun in Korean adults living in Seoul, Gyeonggi, and Chungbuk regions. Among the participants (M=55, F=168, 25y), only 10.4% understood the definition of Yaksun (mainly through the broadcast media). The frequency of Yaksun consumed when eating out was 2~3 times per month in 50.2% of participants. The main reason for choosing a Yaksun menu (46.3% of participants) when eating out was for health. The mean satisfaction score of Yaksun was $3.5{\pm}0.8$ on the five point Likert scale. Participants highly agreed ($3.8{\pm}0.8$) that Yaksun is composed of nutritious foods combined with oriental medicinal herbs for the treatment of disease, which was significantly higher in groups with learning experience on Yaksun (p<0.05). Interestingly, participants showed neutral to the description, that a diet without oriental medicinal herbs is not Yaksun ($3.1{\pm}1.0$), which was significantly different between genders (p<0.05). Men recognized more than women that Yaksun should be based on oriental medical theory (p<0.05) and should be prepared for the prevention or treatment of diseases (p<0.05). In conclusion, the concept and terminology of Yaksun need to be defined and publicized in modern diet.

It has been reported that E. senticosus is effective for strengthening the liver, reduction of blood sugar levels, antistress and rainforcement of stamina. However, most of the extraction from this medicinal plant is imported from foreign countries. Therefore, farmers have tried to grow it in this country even though it is difficult to propagate by seeding method. This study was carried out to improve seeding propagation using seeds in National Honam Agricultural Experinment Station from '92 to '93. The seeds of E. senticosus were immature embryo at the time of gathering seeds in autumn, and needed wet stratification treatment for after-ripening. Embryo elongated slowly for a few days after stratification treatment, and cotyledon started to develop from 40 days after treatment. There were significantly positive correlation between after-ripening period and the ratio of embryo length. Dehiscence was the highest in the ratio of embryo length of 60∼70％, and percentage of dehiscent seed after treatment for 150 days was 76.5％.

Objective The purpose of this review was to investigate exercise therapy by sasang constitution and to offer information for further research. Method The literature was investigated from KMBASE, KISS, ScienceON, JSCM, DBpia, Pubmed. The searching term were sasang, sasang constituion, sasang type, taeyangin, taeeumin, soyangin, soeumin, exercise, physical therapy, physical activity, and so on. Studies were extracted and analyzed exercise by sasang constitution, in addition, were also collected physiological differences related to sasang constitution, exercise ability, exercise response and effects, and exercise contraindications. Result & Conclusion It is helpful for Taeyangin to lower the energy through exercises that train the lower body and deep breathing, and there is no need to exercise excessively. Taeeumin tend to be obese compared to other constitutions. In order to be physically healthy, it is good to sweat a lot through regular exercise. It is good to do aerobic exercise that burns a lot of calories every day. Soyangin has a weak lower body, so it is good to exercise to reinforce the lower body. Soyangin has weak stamina, and since static exercise easily loses interest, it is helpful to do exciting exercise, and it can be performed at normal intensity. Soeumin are statistically less physically active. So soeumin need to improve exercise habits, but because physical strength is on the weak side, it is more appropriate to do an exercise that activates the body parts evenly rather than a strong one.

The modern political scientist Liang, qi-chao (1873-1929), who insisted on the richness of China, was a major axis of Korean intellectuals in the nineteenth century. His patriotism for Chinese reconstruction oppressed by Western powers has greatly influenced Korea 's will to build a modern nation. There was military power and physical education at the center of Liang, qi-chao thought. He emphasized military strength through military strength with a strong stamina, so he mentioned the necessity of military and physical education. Based on the idea of this kind of Liang, qi-chao, the korean intellectuals believed that the Korean people should be born healthy through physical education. The initial introduction of physical education in Korea was integrated with the Military Sports. For the first time, Being introduced Western Sports in 1895, The fact that the army athletic gymnastics was first introduced into school education in 1896 proves this oneness.

Objective: The purpose of this study was to examine of this study is to study the effect of squat exercise on muscle activation in a sling device using various types of ropes and to propose an effective sling exercise method for strengthening the lower extremity strength. Method: 20 adult male subjects (age: 25.2±2.4 yrs, height: 176.5±3.2 cm, weight: 77.2±4.5 kg) participated in this study. In the experiment, a total of four squats were conducted: squat [SE], sling squat using inelastic rope [IR], sling squat using elastic rope [ER], and sling squat using two elastic ropes [TER]. Squats were performed 5 times for each condition, and a 60-second break was given for each condition to minimize muscle fatigue. The activation of biceps brachii, rectus femoris, gastrocnemius, and tibialis anterior muscles was measured. Results: It was found that the activation of all muscles was the lowest during the squat exercise [SE]. During the sling squat using inelastic rope [IR], the muscle activation of the biceps brachii was the highest. During the sling squat using elastic rope [ER], the activation of the rectus femoris, gastrocnemius, and tibialis anterior muscles was found to be the highest. In the sling squat using two elastic ropes [TER], most of the muscle activation was similar to that of the sling squat using inelastic rope [IR]. Conclusion: Our results of the experiment, it was found that sling squat exercise using elastic rope had a positive effect on the activation of all muscles. It is thought that performing a squat exercise under moderate weight load and unstable conditions, such as sling squat exercise using elastic rope, can increase the muscle activity of the lower limbs and perform more effective exercise effect than performing a conventional squat exercise under stable conditions. In the future, if research is conducted not only on adult men, but also on various ages and patients, it will be able to provide positive help in improving balance, stability and stamina through squat exercise.
