Objectives : This study investigated the correlation between the incidence by the climate of the day and the Stems and Branches(干支) of stroke patients. Methods : From January in 2000 to March in 2008, we studied 370 stroke patients hospitalized at Dongguk University Bundang Hospital. Each participant was investigated for the day's average temperature, the day's average air humidity, the day's average wind speed, and the day's Stems and Branches (干支) in oriental medical theory. Results: Concerning the day's average temperature, the group at a temperature under 18 $^{\circ}C$ had the highest risk. For the day's average air humidity, the group at over 60 % humidity showed a higher ratio of stroke. In respect of the day's average wind speed, the group at speeds under 2.26 $^m/s^2$ (the last 5 years average wind speed in Gyeonggi-do) had a higher risk. In the aspect of Stems and Branches (干支), stroke occurred more in Yin day(陰日) than in Yang day(陽日). In the view of the Five Circuits (五運), the Wood (木) was most common followed by Fire(火). Using the relation between Stems and Branches (干支), the mutuality cooperate pattern was more common than the mutuality control group and same characteristic group. Using the Theory of Five Circuits (五運) and Six Qi (六氣), the Fire group (火) showed the highest risk. The Wood group (木) came next. Conclusions : We could suggest that stroke attack might have some significant relationship with climate, stems, and branches in oriental medical theory.

The aim of this study was to determine the seroprevalence and risk factors of fascioliasis in yaks, Bos grunniens, from 3 counties of Gansu Province in China. A total of 1,584 serum samples, including 974 samples from white yaks from Tianzhu, 464 from black yaks from Maqu, and 146 from black yaks from Luqu County, were collected and analyzed using ELISA to detect IgG antibodies against Fasciola hepatica. The overall F. hepatica seroprevalence was 28.7% (454/1,584), with 29.2% in white yaks (284/974) and 27.9% in black yaks (170/610). The seroprevalence of F. hepatica in yaks from Tianzhu, Luqu, and Maqu was 29.2%, 22.6%, and 29.5%, respectively. Female yaks (30.9%) had higher F. hepatica seroprevalence than male yaks (23.4%). Also, F. hepatica seroprevalence varied by different age group from 24.1% to 33.8%. Further, the seroprevalence ranged from 21.8% to 39.1% over different seasons. Interestingly, the season and age of yaks were associated with F. hepatica infection in yaks in the investigated areas. These findings provided a basis for further studies on this disease in yaks from 3 counties of Gansu Province in northwestern China, which may ultimately support the development of effective control strategies of fascioliasis in these areas.

In the 18th century, Xu Lingtai (徐靈胎) and Yoshimasu Todo (吉益東洞) were medical revolutionaries. They emphasized researches about synthesis of formulae, efficacy of medication and observation and then classification of clinical phenomena, so they assumed a modern scientific character. But, there were clear differences between their academic thoughts. In this paper, we examine the causes of difference in three fields, i.e. traditional culture, viewpoints of talented people and academic personality. The first, difference was due to traditional culture. Chinese medicine has a long history and heavy traditional culture. Yin-Yang (陰陽) theory, Five Phase(五行) theory, Viscera and Bowels (臟腑) theory and Meridian and Collateral (經絡) theory stemmed from everyday practice, and Chinese people learn these theories from experience and observation. From the standpoint of Chinese people, particularly scholarly doctors [儒醫] such as Xu Lingtai, it was easy to debate medical theories. In contrast, Japanese traditional culture didn't have as long a history as China. Thus as a necessity, it was harder to disseminate traditional Chinese medicine theories in Japan. Yoshimasu Todo simplified it by cutting out the superfluous traditional Chinese medicine theory, so at that time it must have been shocking to the Japanese medical world's trends. The second, difference was due to viewpoints of talented experts. From the standpoint of Xu Lingtai, above all, medicine is just a learning, only a kind of technique, even more not a means of living. Xu Lingtai was concerned with the appearance of very talented experts such as 'great man' (偉人), and 'exceptional man' (奇士) who carried out medical research. Instead of cultivating a few talented people, Yoshimasu Todo tried to produce a large number of clinicians quickly who could treat ordinary people. The third was due to personality difference. As Xu Lingtai threw away Confucianism and studied medicine in his youth, although he had a critical attitude, he was always mild-mannered. Yoshimasu Todo always had a clearly critical and rebellious nature. Personality influenced their literary spirit and learning style, so although both advocated reactionism, the academic thought of Xu Lingtai was reformative and mild, while that of Yoshimasu Todo was revolutionary and fierce. Xu Lingtai and Yoshimasu Todo had considerably similar research domains and academic thought, so it is proper for them both to serve as examples for making a comparative study of medical history in China and Japan in 18th century.

The present study was conducted to examine the effect of a stair-stepped feed intake pattern on growth, feed efficiency, and meat quality of Hanwoo steers. Twenty-seven 11-month-old Hanwoo steers were randomly divided into three groups. The control group was fed according to the Korean steer feeding program, and the other two groups were fed according to an alternated feeding schedule of 3-2-4-2 months. During the first three months of the experiment, treatment group 1 (T1) and treatment group 2 (T2) were fed 20% and 30% less than the control group, respectively. For the following two months, the T1 group was fed 20% more than the control group while the T2 group was fed 20% less than the control group. In the third step, T1 and T2 groups were fed 20% and 10% less, respectively, than the control group for four months. In the last two months, T1 and T2 groups were fed 20% more than the control group. After the stair-step feeding trial, steers were fed concentrated feed ad libitum for five months. The altered feed intake pattern did not affect daily body weight gain. However, daily feed intake tended to decrease and growth efficiency tended to increase in the two treatment groups compared to the control group. Altered feed intake also affected blood metabolite levels. The serum glucose and BUN level of the T1 group increased in the first re-fed period compared to the T2 and control groups. The serum cholesterol level of the T2 group decreased in the first restricted-re-fed growth period compared to the T1 and control groups. The serum NEFA levels of the two treatment groups increased from the first restricted period compared to the controls. The serum insulin level of the T2 group increased in the last period compared to the T1 and control groups. Regarding meat yield index, the control group was significantly higher than the T2 group (p<0.05). Regarding meat yield grade, the carcass back fat thickness of the T2 group was significantly higher than the control group (p<0.05). In marbling score, the T1 group was the highest (4.9), followed by the control group (4.1) and the T2 group (4.0). These results indicate that using a stair-stepped growth pattern (T1) can contribute to improvements in growth efficiency and muscle marbling.

I have felt seriously a desire to study and analyse the medicine of the period of the Three Kingdoms when I thought and studied the ancient medical history. Therefore in Chapter II I inquired into the background of Politico-social and the currency of thought. In the Chapter III inquired into the system of Medical politics in the period of the Three Kingdoms. In the Chapter IV inquired into the general view of the period of the Three Kingdoms. In the Chapter V inquired into the writings of Medicine and Doctors. From this study, I reached at following-conclusions. 1. The Three Kingdoms are politically opposed to each other, but socialo culturaly cooperated, connected each other to import the technique and thought which developed in China, so generally their system and life pattern are alike. 2. On the system of medical politcics Goguryeo(高句麗) had the system of court phisician, Baek jeo(百濟) had medical doctor and collector in the Ministry of Drug which took charge of teaching and medical treatment and specially had spellchanting doctor who treat epidermic and psychological diease untreated with herb and acupuncture, Shilla(新羅) had the system of Yak chun which was charge of teaching and treatment, and had the Chimbang(針房) which assist doctor in the system of Yagchun(藥典制度). 3. The medical interchange with China made the Three Kingdoms to import the medical books. So the theory of medicine was systematized and the art of treatment developed. In the aspect of Herb the Three Kingdoms and China actively exchange their own district product. 4. The medicine of Three Kingdoms accommodated Yin Yang Ohang theory(陰陽五行說), the theory of body compose with four element(四大 : 地水火風) and the theory of life cultivation and breathing(導引養生說) with Therefore in many aspect of oriental medicine basic theory and treatment would improved. 5. The epidermic diease occurred in period of Three Kingdoms, is represented Yeok(疫), that is after all Ohn Diease(溫病), and epidermic diease, is relfected by earthquake, heavy rain, terrible droughty and eclipse of sun. The treatment of this diease did not developed in that time, we presume that there are many persons killed. 6. As the record of five starr(五星), comet(彗星) and eclipse of sun was showed, the astronomy of oriental medicine in the Three Kingdoms was high level and it became the mothers womb of Korean astronomy. 7. The medicine of the Three Kingdoms, concreted with Chinese medicine and their own ancient one, was reflect on Japanese medicine to improve the medical theory and treatment. 8. The Three Kingdoms peculiarly published Korea Nosabang(高麗老師方) Baekjyeo Shinjipbang(百濟新集方), so this independent medicine reflected on the development of natural hurb(鄕約) of the period of Korea(高麗).

Background: The prognosis of patients with hepatocellular carcinoma (HCC) after curative resection varies greatly. Few studies had investigated the risk factors for early recurrence (recurrence-free time ${\leq}$ 1 year) of hepatitis B virus (HBV)-related HCCs meeting Milan criteria. Methods: A retrospective analysis was performed on the 224 patients with HCC meeting Milan criteria who underwent curative liver resection in our center between February 2007 and March 2012. The overall survival (OS) rate, recurrence-free survival (RFS) rate and risk factors for early recurrence were analyzed. Results: After a median follow-up of 33.3 months, HCC reoccurred in 105 of 224 patients and 32 died during the period. The 1-, 3- and 5-year OS rates were 97.3%, 81.6% and 75.6% respectively, and the 1-, 3- and 5-year RFS rates were 73.2%, 53.7% and 41.6%. Cox regression showed alpha-fetoprotein (AFP) > 800 ng/ml (HR 2.538, 95% CI 1.464-4.401, P=0.001), multiple tumors (HR 2.286, 95% CI 1.123-4.246, P=0.009) and microvascular invasion (HR 2.518, 95% CI 1.475-4.298, P=0.001) to be associated with early recurrence (recurrence-free time ${\leq}$ 1-year) of HCC meeting Milan criteria. Conclusions: AFP > 800 ng/ml, multiple tumors and microvascular invasion are independent risk factors affecting early postoperative recurrence of HCC. In addition resection appears capable of replacing liver transplantation in some situations with safety and a better outcome.

The present study aimed to explore the neuroprotective effect and possible mechanisms of rhGLP-1 (7-36) against transient ischemia/reperfusion injuries induced by middle cerebral artery occlusion (MCAO) in type 2 diabetic rats. First, diabetic rats were established by a combination of a high-fat diet and low-dose streptozotocin (STZ) (30 mg/kg, intraperitoneally). Second, they were subjected to MCAO for 2 h, then treated with rhGLP-1 (7-36) (10, 20, $40{\mu}g/kg$ i.p.) at the same time of reperfusion. In the following 3 days, they were injected with rhGLP-1 (7-36) at the same dose and route for three times each day. After 72 h, hypoglycemic effects were assessed by blood glucose changes, and neuroprotective effects were evaluated by neurological deficits, infarct volume and histomorphology. Mechanisms were investigated by detecting the distribution and expression of the nuclear factor erythroid-derived factor 2 related factor 2 (Nrf2) in ischemic brain tissue, the levels of phospho-PI3 kinase (PI3K)/PI3K ratio and heme-oxygenase-1 (HO-l), as well as the activities of superoxide dismutase (SOD) and the contents of malondialdehyde (MDA). Our results showed that rhGLP-1 (7-36) significantly reduced blood glucose and infarction volume, alleviated neurological deficits, enhanced the density of surviving neurons and vascular proliferation. The nuclear positive cells ratio and expression of Nrf2, the levels of P-PI3K/PI3K ratio and HO-l increased, the activities of SOD increased and the contents of MDA decreased. The current results indicated the protective effect of rhGLP-1 (7-36) in diabetic rats following MCAO/R that may be concerned with reducing blood glucose, up-regulating expression of Nrf2/HO-1 and increasing the activities of SOD.

Objectives: This study used semiology based on traditional Chinese medicine (TCM) to investigate vital energy (Qi) behavior in women with abdominal myofascial pain syndrome (AMPS). Methods: Fifty women diagnosed with chronic pelvic pain (CPP) secondary to AMPS were evaluated by using a questionnaire based on the theories of "yin-yang," "zang-fu", and "five elements". We assessed the following aspects of the illness: symptomatology; specific location of myofascial trigger points (MTrPs); onset, cause, duration and frequency of symptoms; and patient and family history. The patients tongues, lips, skin colors, and tones of speech were examined. Patients were questioned on various aspects related to breathing, sweating, sleep quality, emotions, and preferences related to color, food, flavors, and weather or seasons. Thirst, gastrointestinal dysfunction, excreta (feces and urine), menstrual cycle, the five senses, and characteristic pain symptoms related to headache, musculoskeletal pain, abdomen, and chest were also investigated. Results: Patients were between 22 and 56 years old, and most were married (78%), possessed a elementary school (66%), and had one or two children (76%). The mean body mass index and body fat were 26.86 kg/cm2 (range: 17.7 - 39.0) and 32.4% (range: 10.7 - 45.7), respectively. A large majority of women (96%) exhibited alterations in the kidney meridian, and 98% had an altered gallbladder meridian. We observed major changes in the kidney and the gallbladder Qi meridians in 76% and 62% of patients, respectively. Five of the twelve meridians analyzed exhibited Qi patterns similar to pelvic innervation Qi and meridians, indicating that the paths of some of these meridians were directly related to innervation of the pelvic floor and abdominal region. Conclusion: The women in this study showed changes in the behavior of the energy meridians, and the paths of some of the meridians were directly related to innervation of the pelvic floor and abdominal region.

The main purpose of this study is to differentiate Sasang Constitutions of men and women by measuring 5 parts of the body. By the definitions about Four Chos(四焦) in ${\ulcorner}$The Discourse on Viscera and Bowels(臟腑論)${\lrcorner}$, the body is divided into four parts and sets up the five borderlines. They are Top-line, Bosom-line, Stomach-line, Navel-line and Bottom-line. Top-line(第一線) is the horizontal distance between Rt. & Lt. Coracoid processes passing through the acupuncture point CV-22(天突穴) or the horizontal distance between Rt. & Lt. beginning points of Axillary lines. Bosom-line(第二線) is the horizontal distance passing through Rt.& Lt. Nipples. Stomach-line(第三線) is the horizontal distance passing through Rt.& Lt. acupuncture point ST-19(不容穴). Navel-line(第四線) is the horizontal distance passing through the navel(CV-8; 神闕穴) and the acupuncture point ST-25(天樞穴). Bottom-line(第五線) is the horizontal distance between Rt. & Lt. Anterior Superior Iliac Spine(ASIS). The measured numerical values of Five Lines are the most important factors to classify the Four Constitutions(Taeyangin, Taeumin, Soyangin, Soeumin). Among the five lines, Stomach-line(Middle-line) is the base line to decide Yin and Yang. As a result, I could differentiate the four Constitutions as follows. 1. Taeyangin's Top-line is more than 36cm long. Top-line is the longest. Bottom-line is the shortest. The length-difference between Top-line and Bottom-line is more or less 10cm long. 2. In case of Taeumin, Navel-line is the longest. The numerical values of Middle and Bottom lines are almost the same or Bottom-line is shorter than Middle-line by 1 or 2 cm long. In some special case, the five lines are all the same and the body just looks like a log. 3. In case of Soyangin, just like Taeyangin, Top-line is the longest. Bottom-line is the shortest. The length of Top-line is ranged between 30cm to 35cm long. From Top-line to Bottom-line, the length gradually diminishes each by 2cm: for example, 34-32-30-28-26. 4. In case of Soeumin, the longest one is Bottom-line. Specially, Navel-line is shorter than Middle-line. Bottom-line is longer than the Middle.
