The purpose of the study is to examine the effects of the positive menial stress, eustress, on autonomic nervous system(ANS) and human health. For this, we analyzed heart rate variability(HRV) parameters, the most promising markers of ANS function to assess the changes of emotional and physiological states of human body. We measured HRV Signal of World Cup group(281 male subjects: $29.8{\pm}5.6yr$., 187 female subjects: $29.0{\pm}5.4yr$.) in two stadiums at least an hour before the game during '2002 FIFA World Cup Korea/Japan' event. We also measured control group's(331 male subjects: $30.9{\pm}4.7 yr$., 344 female subjects: $30.2{\pm}5.2 yr$.) in the health promotion centers in two university hospitals at least a month before and after the world cup event period. Considering physiological differences between males and females, the data analysis was applied to 'male group' and 'female group' separately. As a result, some tendency was observed that is different from what we have known as the stress reaction. In general, all parameter values except that of mean heart rate tend to decrease under stressed condition. However, under eustressed condition, both heart rate and standard deviation of the Normal to Normal intervals(SDNN) were higher then those of normal condition(p<0.05). Especially, in case of female group, contrary to distressed condition, every frequency-domain powers showed tile higher value(p<0.05, p<0.001). Considering that decrease of HRV indicates the loss of one's health, the increase of SDNN and frequency parameters means that homeostasis control mechanism of ANS is functioning positively. Accordingly, induction of eustress from international sports event may affect positively to the people's health.

Purpose : Thymus is a lymphoproliferative organ that changes size in various physiological states in addition to some pathological conditions. Thymus is susceptible to involution, and shows a dramatic response to severe stress. Thymic measurements may be helpful in various diseases. UTI (urinary tract infection) is most common bacterial infection in infants and VUR (vesicoureteral reflux) is a common abnormality associated with UTI. In our study, the size of thymus was compared on the premise that a greater stress is exerted on the body when UTI is accompanied by VUR, than when occurs on its own. Methods : Thymic size was measured on standard chest anteroposterior radiographs and expressed as the ratio between the transverse diameter of the cardiothymic image at the level of the carina and that of the thorax (CT/T). The medical records of 99 febrile urinary tract infection infants without other genitourinary anomalies except VUR were reviewed retrospectively. Results : Among 99 patients with febrile UTIs, 25 were febrile UTI without VUR and 74 with VUR. For the UTI with VUR group, there was a significant decrease in the thymic size compared to the those without VUR group ($0.382{\pm}0.048$ vs $0.439{\pm}0.079$, P<0.05). However, there were no differences in the duration of fever and WBC, CRP between the UTI with VUR and UTI without VUR. In addition, there were no differences in the cardiothymic/thoracic ratios between renal defects and renal scars in febrile UTI patients. Conclusion : The results of this study show that the shirinkage of thymus was more frequently found in the UTI patients with VUR. Therefore, awareness of the risks associated with thymic size is important for the appropriate work up and management of UTI patients.

According to the Leukemia and Lymphoma Society, leukemia is a malignant disease (cancer) that originates in a cell in the marrow. It is characterized by the uncontrolled growth of developing marrow cells. There are two major classifications of leukemia: myelogenous or lymphocytic, which can each be acute or chronic. The terms myelogenous or lymphocytic denote the cell type involved. Thus, four major types of leukemia are: acute or chronic myelogenous leukemia and acute or chronic lymphocytic leukemia. Leukemia, lymphoma and myeloma are considered to be related cancers because they involve the uncontrolled growth of cells with similar functions and origins. The diseases result from an acquired (not inherited) genetic injury to the DNA of a single cell, which becomes abnormal (malignant) and multiplies continuously. In the United States, about 2,000 children and 27,000 adults are diagnosed each year with leukemia. Treatment for cancer may include one or more of the following: chemotherapy, radiation therapy, biological therapy, surgery and bone marrow transplantation. The most effective treatment for leukemia is chemotherapy, which may involve one or a combination of anticancer drugs that destroy cancer cells. Specific types of leukemia are sometimes treated with radiation therapy or biological therapy. Common side effects of most chemotherapy drugs include hair loss, nausea and vomiting, decreased blood counts and infections. Each type of leukemia is sensitive to different combinations of chemotherapy. Medications and length of treatment vary from person to person. Treatment time is usually from one to two years. During this time, your care is managed on an outpatient basis at M. D. Anderson Cancer Center or through your local doctor. Once your protocol is determined, you will receive more specific information about the drug(s) that Will be used to treat your leukemia. There are many factors that will determine the course of treatment, including age, general health, the specific type of leukemia, and also whether there has been previous treatment. there is considerable interest among basic and clinical researchers in novel drugs with activity against leukemia. the vast history of experience of traditional oriental medicine with medicinal plants may facilitate the identification of novel anti leukemic compounds. In the present investigation, we studied 31 kinds of anti leukemic medicinal plants, which its pharmacological action was already reported through many experimental articles and oriental medical book: 『pharmacological action and application of anticancer traditional chinese medicine』 In summary: Used leukemia cellline are HL60, HL-60, Jurkat, Molt-4 of human, and P388, L-1210, L615, L-210, EL-4 of mouse. 31 kinds of anti leukemic medicinal plants are Panax ginseng C.A Mey; Polygonum cuspidatum Sieb. et Zucc; Daphne genkwa Sieb. et Zucc; Aloe ferox Mill; Phorboc diester; Tripterygium wilfordii Hook .f.; Lycoris radiata (L Her)Herb; Atractylodes macrocephala Koidz; Lilium brownii F.E.

This thesis study of the medical concept Qiu Zheng Lu (求正錄) is discussed in the Lei Jing Fu Yi (類經附翼), a book authored by Zhang Jie Bin (張介賓) a medical doctor during the Chinese Ming (明) dynasty (1368-1683). The meaning of Qiu Zheng Lu (求正錄) is "searching for the rightness." In his book Zhang Jie Bin (張介賓) intended to clarify Qiu Zheng Lu (求正錄) by delineating the concept into four categories. These are: Sanjiao Baoluo Mingmen Bian (三焦包絡命門 辨) the theory of the triple warmer, the Pericardium, the Gate of Life ; Da Bao Lun (大寶論) the theory of the great treasure of the human body; Zhen Yin Lun (眞陰論) the theory of true-yin fluid; and Shi Er Zang Mai Hou Bu Wei Lun (十二臟脈候部位論) the theory of the part of the pulse and its condition in regards to the twelve viscera. Sanjiao Baoluo Mingmen Bian (三焦包絡命門辨), the theory of the triple warmer, the Pericardium, the Gate of Life. The triple warmer (三焦: Sanjiao) is composed of three parts: the upper, middle, and lower. This concept is also connected with the functions and roles of the vital organs. The upper burner is related to the heart and lungs. The middle burner is related to the liver and spleen. Whereas, the lower burner is related to the kidneys. Bao-Luo (包絡) is the Pericardium, the envelope of the heart, serving as the protector of the heart. Ming-Men (命門) is the Gate of Life, reffering to the vitals of life. It functions as kidney-yang which is considered as the origin of yang-energy of the human body, and serves partly as the function of cortico-adrenal gland in modern medicine. Zhang Jie Bin (張介賓) discussed the Da Bao Lun (大寶論) as the most important function in the human body because the Da Bao (大寶/great treasure) is the true-yang (眞陽) which is the affective force for physiological functions, and as the source of energy for life activities. Moreover, true-yang (眞陽) functions both as a heater and thermometer that warms the human body and indicates vitality by levels of body warmth respectively. The Zhen Yin Lun (眞陰論) theory states that if true-yang (眞陽) is energy, then true-yin (眞陰) is the source of energy. This can be likened to a tree with roots which absorbs nutrients from the ground (source), and spreads the nutrients (energy) through its branches. Thus, true-yin (眞陰) is the root cause for later functional activities of true-yang (眞陽). In Shi Er Zang Mai Hou Bu Wei Lun (十二臟脈候部位論) the theory of the pulse (脈 /Mai) and its condition in regards to the twelve viscera, Zhang Jie Bin (張介賓) insisted that when a diagnoses by the pulse is made the five vital organs and the six viscera (五臟六腑) of a human body should be harmoniously arranged in accordance with its respective part of the pulse. Furthermore, Zhang Jie Bin (張介賓) supported his theory with evidence from earlier Chinese medical doctors. And, by stating that human beings must cultivate and preserve their true-yin (眞陰) and true-yang (眞陽) energies he therefore created four new prescriptions called: Zuoguiyin (左歸飮), Youguiyin (右歸飮), Zuoguiwan (左 歸丸), Youguiwan (右歸丸). To further clarify his theory Zhang Jie Bin (張介賓) considered that the function of true-yang (眞陽) and true-yin (眞陰) is expressed by Ming-Men (命門). This theory is that for humans to be spiritually and physically healthy they must live in accord with natural law. Also, within the framework of natural law, astronomical and geographical factors must be considered for complete, holistic, health. Thus, Ming-Men is the basis for healthy living in the modern world.

Ginseng is the English common name for the species in the genus Panax. This article gives a broad botanical review including the morphological characteristics, ecological amplitude, and the ethnobotanical aspect of the genus Panax. The species of Panax are adapted for life in rich loose soil of partially shaded forest floor with the deciduous trees such as linden, oak, maple, ash, alder, birch, beech, hickory, etc. forming the canopy. Like their associated trees, all ginsengs are deciduous. They require annual climatic changes, plenty of water in summer, and a period of dormancy in winter. The plant body of ginseng consists of an underground rhizome and an aerial shoot. The rhizome has a terminal bud, prominent leafscars and a fleshy root in some species. It is perennial. The aerial shoot is herbaceous and annual. It consists of a single slender stem with a whorl of digitately compound leaves and a terminal umbel bearing fleshy red fruits after flowering. The yearly cycle of death and renascence of the aerial shoot is a natural phenomenon in ginseng. The species of Panax occur in eastern North America and eastern Asia, including the eastern portion of the Himalayan region. Such a bicentric generic distributional pattern indicates a close floristic relationship of the eastern sides of two great continental masses in the northern hemisphere. It is well documented that genera with this type of disjunct distribution are of great antiquity. Many of them have fossil remains in Tertiary deposits. In this respect, the species of Panax may be regarded as living fossils. The distribution of the species, and the center of morphological diversification are explained with maps and other illustrations. Chemical constituents confirm the conclusion derived from morphological characters that eastern Asia is the center of species concentration of Panax. In eastern North America two species occur between longitude $70^{\circ}-97^{\circ}$ Wand latitude $34^{\circ}-47^{\circ}$ N. In eastern Asia the range of the genus extends from longitude $85^{\circ}$ E in Nepal to $140^{\circ}$ E in Japan, and from latitude $22^{\circ}$ N in the hills of Tonkin of North Vietnam to $48^{\circ}$ N in eastern Siberia. The species in eastern North America all have fleshy roots, and many of the species in eastern Asia have creeping stolons with enlarged nodes or stout horizontal rhizomes as storage organs in place of fleshy roots. People living in close harmony with nature in the homeland of various species of Panax have used the stout rhizomes or the fleshy roots of different wild forms of ginseng for medicine since time immemorial. Those who live in the center morphological diversity are specific both in the application of names for the identification of species in their communication and in the use of different roots as remedies to relieve pain, to cure diseases, or to correct physiological disorders. Now, natural resources of wild plants with medicinal virtue are extremely limited. In order to meet the market demand, three species have been intensively cultivated in limited areas. These species are American ginseng (P. quinquefolius) in northeastern United States, ginseng (P. ginseng) in northeastern Asia, particularly in Korea, and Sanchi (P. wangianus) in southwestern China, especially in Yunnan. At present hybridization and selection for better quality, higher yield, and more effective chemical contents have not received due attention in ginseng culture. Proper steps in this direction should be taken immediately, so that our generation may create a richer legacy to hand down to the future. Meanwhile, all wild plants of all species in all lands should be declared as endangered taxa, and they should be protected from further uprooting so that a. fuller gene pool may be conserved for the. genus Panax.

Choline, an essential nutrient for humans, is required for the structural integrity of the cell membranes, methyl-group metabolism, synthesis of the neurotransmitter acetylcholine, synthesis of the membrane phospholipid components of the cell membranes, and the transport of lipids and cholesterol. Choline can be synthesized in the body, but it is insufficient to meet the daily requirements and hence it must be obtained through the diet. In the United States/Canada, Australia/New Zealand, Europe, China, and Taiwan, the adequate intake (AI) and tolerable upper intake level (UL) of choline have been established, while the establishment of the 2020 Dietary Reference Intakes for Koreans (KDRI) for choline was postponed due to the lack of a choline database for Korean foods and studies on the choline intake of Koreans. However, as part of the preparation work for the 2020 DRI revision and finalization, choline intake and the possibility of disease occurrence were verified through analysis of published data. The groundwork for the subsequent establishment of a choline DRI was laid through a literature search, evaluation, and review of the literature reported from 1949 up to 2019. This can be regarded as the culmination of this project. According to the results of randomized controlled trials (RCTs), cohort studies, case-control studies, and cross-sectional observational studies in humans, approximately 400-500 mg/day of choline intake was effective in preventing liver function damage (fatty liver), neural tube damage, cardiovascular disease, breast cancer, and cognitive function improvement. The same amount of choline intake, however, also correlated with the risk of prostate and colorectal cancer. At present, there is limited information available on choline intake and health outcomes, particularly for the Korean population. More human studies, including clinical trials on the requirements and the physiological benefits associated with dietary intake, are needed to establish the KDRI for choline.
