The result is the followings after investigating composition, dosage and usage of Sagunjatang(四君子湯), Samultang(四物湯), Palmultang(八物湯), Sipjeondaebotang(十全大補湯) in literature by country and Era 1. Sagunjatang has become equal to Panax ginseng(人蔘), Atractylodes japonica(白朮), Poria cocos(복령) each for 2 Jeon(錢), Glycyrrhiza uralensis(甘草) 1 jeon since the Ming Dynasty in China and it is standardized by Panax ginseng, Atractylodes japonica, Poria cocos and Glycyrrhiza uralensis each for 1 Jeon 2 Pun(分) 5 Ri(里) since Dongeuibogam in Korea. 2. Samultang has become equal to Angelica gigas(當歸) and Rehmannia glutinosa(地黃) each three Jeon, Cnidium officinale(川芎) is 1 Jeon 2 Pun or 1 jeon and Paeonia lactiflora(芎藥) 2 Jeon since the Ming Dynasty in China and it is standardized by Angelica gigas, Cnidium officinale, Paeonia lactiflora and Rehmannia glutinosa each for 1 Jeon 2 Pun 5 Ri since Dongeuibogam in Korea. 3. In the case of Palmultang, compositional usage of medicine was different in the Ming Dynastry and the Ching(靑) Dynastry in China. Total dosage was increased and ratio of Angelica gigas and Rehmannia glutinosa was increased comparatively in the Ching Dynasty. All prescription of medicine was consisted of 1 Jeon 2 Pun and specific dosage was presented except Euirimchwalyo(醫林撮要) that dosage was not recorded in Korea. 4. Sipjeondaebotang tended to increase total dosage in the latter part in China. Dosage was mostly used 1 Jeon thus Dongeuibogam but Bangyakhap(方藥合編) used 1 Jeon 5 Pun differentially.

Hookworm infections are widely prevalent in tropical and subtropical areas, especially in low income regions. In the body, hookworms parasitize the proximal small intestine, leading to chronic intestinal hemorrhage and iron deficiency anemia. Occasionally, hookworms can cause overt gastrointestinal bleeding, but this is often ignored in heavily burdened individuals from endemic infectious areas. A total of 424 patients with overt obscure gastrointestinal bleeding were diagnosed by numerous blood tests or stool examinations as well as esophagogastroduodenoscopy, colonoscopy, capsule endoscopy or double-balloon enteroscopy. All of the patients lived in hookworm endemic areas and were not screened for hookworm infection using sensitive tests before the final diagnosis. The patients recovered after albendazole treatment, blood transfusion, and iron replacement, and none of the patients experienced recurrent bleeding in the follow-up. All the 31 patients were diagnosed with hookworm infections without other concomitant bleeding lesions, a rate of 7.3% (31/424). Seventeen out of 227 patients were diagnosed with hookworm infections in the capsule endoscopy (CE), and 14 out of 197 patients were diagnosed with hookworm infections in the double balloon enteroscopy (DBE). Hookworm infections can cause overt gastrointestinal bleeding and should be screened in patients with overt obscure gastrointestinal bleeding (OGIB) in endemic infectious areas with sensitive methods. Specifically, the examination of stool specimens is clinically warranted for most patients, and the proper examination for stool eggs relies on staff's communication.

Obstetrics and Gynecology include gynecology which is concerned with the treatment for the disease based on physiology and pathology of women, and obstetrics which is concerned with pregnancy delivery. These obstetrics and gynecology can be said to da-te from the birth of human beings. This pap-er has carried on the studies about the deve-loping process of obstetrics and gynecology of Ming and Qing age. The results of this study are as follows: In Ming age, Many Obstetrics and Gynecology books including "Nukecuoyao"("女科撮要"), "Xiaozhufurenliangfang"("校注婦人良方"), "Wanshifurenke"("萬氏婦人科") and "Nukezhingzhizhunsheng"("女科證治准繩") were published Distinction in Ming age we-re equal development on theory and clinic t-aking a serious view of the differentiation of symptoms and signs, fashion of medicine th-ought of reactionism under the influence of "lixue"(理學). The refore Obstetrics and Gyn-ecology were influenced by these points. And for this example, as treatment contents on "Xiaozhufurenliangfang"("校注婦人良方") and the theory about "fetuse-energy"(胎氣) in "Furengui"("婦人規"), theoretic system with a view point's change of women's disease were established on Obstetrics and Gynecology. But it was restricted on a field of diagnosis under the influence of feudal "lixue"(理學), so the the number of obstetrics doc-tors who were mostly men at that time had fallen greatly and maternity who were short of expert medical knowledge appeared. In Qing age, an explosive increase in po-pulation called greater demand on medicine book and generation after generation extre-mely much Obstetrics and Gynecology books including "NukeChanhoubian"("女科産後編"), "Yetianshinuke"("葉天士女科"), and "Shenshinukejiyao"("沈氏女科輯要") were p-ublished, and it is studied that application of "eight extra-channel"(奇經八脈) theory and the study of drug attributive on extra-chan-nel were progressed. Besides, it is studied that existing traditional Obstetrics and Gyn-ecology changed newly under the influence of the school of combination of traditional Chinese medicine and western medicine which was appeared in the late Qing age.

Chewing betel quid is associated with an increased risk of oral cancer. The betel quid chewed in Taiwan includes the inflorescence of Piper betle, which contains high concentrations of safrole (15 mg/fresh weight). Piper betle leaf is also used in betel quid; however, the concentration of safrole in betel leaf has not been documented. Chewing betel quid may contribute to safrole exposure in man (420 mm in saliva). Using $a^{32}$P-postlabeling method, we have recently demonstrated the presence of stable safrole-like DNA adducts in human oral tissues following betel quid chewing. Safrole is a rodent hepatocar-cinogen, and the real nature of safrole-DNA adducts in human tissues beside oral has not been elucidated. In this paper, we tested the safrole DNA adducts forming potential in human hepatic and oral derived cells by the ${32}^P$-postlabeling technique. The results suggest that oral cancer derived cell OC-2 alone is not able to form safrole-DNA adduct. However, safrole DNA adducts can be detected following I'-hydroxysafrole, a proximate safrole metabolite, treatment. In addition, pretreament of cytochrome P450 inducers also enhanced the formation of previously undetectable safrole DNA adducts. This finding couples with our previous results suggest that oral may serve as a target tissue for safrole, and safrole may be involved in oral carcinogenesis.

Background: Central lymph node metastasis(CLNM) is common in papillary thyroid microcarcinoma (PTMC). The aim of this study was to define the pathohistologic risk grading based on surgical outcomes. Materials and Methods: Statistical analysis was performed to figure out the optimal cut-off values of size in preoperative ultrasound images for defining the risk of CLNM in papillary thyroid microcarcinoma. Receiver operating characteristic curves (ROC) studies were carried out to determine the cutoff value(s) for the predictor(s). All the patients were divided into two groups according to the above size and the clinic-pathological and immunohistochemical parameters were compared to determine the significance of findings. Results: The optimal cut-off value of tumor size to predict the risk of CLNM in papillary thyroid microcarcinoma was 0.575 cm (area under the curve 0.721) according to the ROC curves. Significant differences were observed on the multifocality, extrathyroidal extension and central lymph node metastasis between two groups which were divided according to the tumor size by the cutoff values. Patients in two groups showed different positive rate and intensity of Ki67. Conclusions: The size of PTMC in ultrasound images are helpful to predict the aggressiveness of the tumors, it could be an easy predictor for PTMC prognosis and assist us to choose treatment.

This study concerns of how the Qing dynasty overcame the national inferiority on the process of the Ming-Qing war in the East Asia during the early 17th century. Historically the Qing came forward in succession the total 12 Emperors whose posthumouses were recorded according to a respective independent system. These studies will be commented the alliance between Manchurian and Mongolian tribes. As the researching result, it will be commented that the Qing's emperors possessed the names of the Emperor of Han's race, Khan of Mongolian tribe, Han of Manchurian clan at the same time. Furthermore in other to follow the war against the Ming dynasty the Qing dynasty promoted positively the strategic alliance through the marriage connection with Mongolian royal family. And the Qing dynasty succeeded in organizing the Military Eight Banners so that Qing dynasty could utilize the reorganized social civilian groups into the avaliable groups to the battle. Thus this Eight Banners were comprehended all members who were not only the Mongolian clans allianced but also the submitted soldiers from the Ming in the war.

Objective: Findings for associations between the methylenetetrahydrofolate reductase (MTHFR) A1298C gene polymorphism and head and neck cancer risk have been conflicting. We therefore performed a meta-analysis to derive a more precise relationship. Methods: Ten published case-control studies were collected and odds ratios (ORs) with 95% confidence intervals (CIs) were used to assess the association between MTHFR A1298C polymorphism and head and neck cancer risk. Sensitivity analysis and publication bias assessment also were performed to guarantee the statistical power. Results: Overall, no significant association between MTHFR A1298C polymorphism and head and neck cancer risk was found in this meta-analysis (C vs. A: OR=1.04, 95%CI=0.87-1.25, P=0.668, Pheterogeneity<0.001; CC vs. AA: OR=1.07, 95%CI=0.70-1.65, P=0.748, $P_{heterogeneity}<0.001$; AC vs. AA: OR=1.06, 95%CI=0.88-1.27, P=0.565, $P_{heterogeneity}<0.001$; CC+AC vs. AA: OR=1.06, 95%CI=0.86-1.30, P=0.571, $P_{heterogeneity}<0.001$; CC vs. AA+AC: OR=1.02, 95%CI=0.69-1.52, P=0.910, $P_{heterogeneity}<0.001$). Similar results were also been found in succeeding analysis of HWE and stratified analysis of ethnicity. Conclusion: In conclusion, our meta-analysis demonstrates that MTHFR A1298C polymorphism may not be a risk factor for developing head and neck cancer.

A study was carried out to compare the food cultures among Korea (Chosun dynasty), China (Ming, thing dynasty) and Japan (Muromachi, Edo era) from 14 century to 19 century. For this study, geographical environments, historical background with the times were researched and also bibliographies related on food cultures were compared among these three countries. There were special geographical environments in three countries upon their territories and geographical features. Historically, in those era, the livelyhoods of the common people in three countries were difficult considerably because of the disturbances of war in the inside and outside of the countries. But the food cultures of three countries were changed owe to introduce the new western culture and institutions. And also there were numerous bibliographies related on food culture which were published from 14C to 19C in Chosun dynasty, Ming and Ching dynasty, and Muromachi, Edo era. They were shown to be the most in Japan, and order of China and Korea followed them. The bibliographies of Ming and thing dynasty showed less than those of Edo era for considering their population and territory, comparatively. In Japan, the biliographies related on food culture of Edo era was given the term of the age of cookery books. It was thought to be resulted from that the peoples of Japan were concerned about cooking and had more chances to contact foreign culture earlier than other country.
