  • Duck is an important domestic animal, especially in Asia. Eighty five percent of ducks in the world are kept in Asia, especially in the East and South Asia regions. The ancestor of domesticated ducks was mallard (Anas platylhynchos), which are still migrating between north and southern parts in Eurasia. Ducks have been domesticated in China for at least 3000 years ago. Phylogenetic studies on ducks, employing electrophoresis of blood proteins, indicate a marked difference of genetic constitution between duck breeds in southeast Asia and those in northeast Asia. Duck embryonic ovary is much more active in secretion of sex steroid hormones especially estradiol than the embryonic testes. Estradiol secreted by the embryonic left ovary has an important role in female sexual differentiation in ducks. In the female ducks, plasma LH, estradiol and testosterone levels increase and reach peaks shortly before the first egg, while progesterone level reach a peak shortly after the first egg. In laying ducks oviposition mostly occurs in the last 3 hr of darkness and first hr of light ranging 02:00-06:00 under 14 hr light (05:00-19:00) and 10 hr darkness photoperiodic condition. Measurements of plasma hormone levels reveal that onset of darkness is a major signal for LH release from the pituitary and the subsequent release of progesterone from ovary, and for induction of ovulation in the female duck.

  • Objectives The purpose of this study is to investigate recent clinical studies on the effect of herbal medicine for pediatric tonsillitis in China, and to seek better methods to treat and study for pediatric tonsillitis in Republic of Korea. Methods We searched clinical studies from the China National Knowledge Infrastructure (CNKI) by search formula (SU='扁桃体炎'+'扁桃炎'+'扁桃腺炎'+'乳蛾'+'喉蛾'+'蚕蛾'+'石蛾'+'珠蛾'+'肉蛾'+'乳蛾風'+爛乳風'+'tonsillitis') and (SU='中樂'+'中医樂'+'本草'+'湯'+'丸'+'散'+'方'+'顆粒'+'膠囊'+'自擬'+'herb'+'herbal'+'decoction'+'remedy'+'Chinese medicine'+'Korean medicine'+'kampo'+'formula'+'herbal drug'+'Chinese drug'+'plant'+'Chinese prescription'+'traditional medicine'+'Medicine, East Asian Traditional'+'Herbal Medicine') in professional search from January 2016 to August 2020. We analyzed the literature focusing on the treatment methods and results. Results Among 1464 searched studies, 35 randomized controlled trials were selected and analyzed. In most studies, the effectiveness of oral administration of herbal medicine on pediatric tonsillitis was significant. Most commonly used herbs were Fructus Forsythiae (連翹), Radix Glycyrrhizae (甘草), Radix Scutellariae (黃芩), Herba Menthae (薄荷), Fructus Arctii (牛蒡子), Radix Scrophulariae (玄蔘), Radix Platycodi (桔梗), Flos Lonicerae (金銀花), Radix Isatidis (板藍根), Radix Bupleuri (柴胡), Fructus Gardeniae (梔子), Rhizoma Belamcandae (射干), Radix et Rhizoma Rhei (大黃), Gypsum Fibrosum (石膏). Conclusions By analyzing the improvement of indicators such as total effective rate, cured rate, symptom disappearance time and symptom score, we found that herbal medicine treatment can help improve pediatric tonsillitis. However, additional studies are needed to solidify these findings.

  • Objectives: Facial diagnosis is an important part of clinical diagnosis in traditional East Asian Medicine. In this paper, we proposed a model to quantitatively classify cold sensitivity using a fully automated facial image analysis system. Methods: We investigated cold sensitivity in 452 subjects. Cold sensitivity was determined using a questionnaire and the Cold Pattern Score (CPS) was used for analysis. Subjects with a CPS score below the first quartile (low CPS group) belonged to the cold non-sensitivity group, and subjects with a CPS score above the third quartile (high CPS group) belonged to the cold sensitivity group. After splitting the facial images into train/validation/test sets, the train and validation set were input into a convolutional neural network to learn the model, and then the classification accuracy was calculated for the test set. Results: The classification accuracy of the low CPS group and high CPS group using facial images in all subjects was 76.17%. The classification accuracy by sex was 69.91% for female and 62.86% for male. It is presumed that the deep learning model used facial color or facial shape to classify the low CPS group and the high CPS group, but it is difficult to specifically determine which feature was more important. Conclusions: The experimental results of this study showed that the low CPS group and the high CPS group can be classified with a modest level of accuracy using only facial images. There was a need to develop more advanced models to increase classification accuracy.

  • Objectives : The present study was conducted to unveil the existence of a medical technique called Chicken-foot-shaped needling method("Gaejokchimbup") from the mid-Chosen Dynasty era and for historical investigation of this technique. Methods : Among historical literatures from China, Korea, and Japan on acupuncture and moxibustion, mentions of "Gaejok"(chicken foot) were searched for and studied. Results : Among the Chinese literatures, some medical scholars made references to "chicken foot" after mentioned in Lingshu Jing. In the Korean literatures, Donguibogam gave it the name Gaejokchimbup and mentioned it. In Japan's Chimgugeukbeecho which contains the acupuncture and moxibustion knowledge of Korean doctors, the procedural method was explained in detail. Conclusions : According to these ancient medical literatures, Gaejok was used largely in two meanings. First meaning was performing acupuncture with 3~4 needles in a chicken foot-like shape on a narrow area, whereas the second meaning was using one acupuncture needle and repeatedly inserting the needle while changing directions according to a path in the shape of a chicken's foot. Based on Rumenshiqin and Chimgugeukbeecho, which contain records of actual clinical experiences, Gaejokchimbup appears to have been used as the second method mention above.

  • "Donguibogam" has been published several times in Japan and China since the first was published and established itself as representing the East Asian medicine in 17th Century. Also, modern far has attracted attention as a major classic book of Korea medicine. For these "Donguibogam" its contents, as well as several medical historians and bibliographers were early comment on versions. However, these prior studies did not confirm about the various editions of the publication time, especially for the initial wood-block edition estimate only. Through this new study found the following facts. First, Wood-block edition of two Jeollagamyeong published until the mid-18th century to be confirmed by the "Seungjeongwonilgi". Second, the timing of the editions published later modified in Naeuiwon is confirmed by the "Chakpan Catalog" and the "Seungjeongwonilgi". Third, the person who keeps wood-block edition of Chonnamgamyeong is the first empirical examples of the same edition. Fourth, the edition is not published editions group that bypasses the Naeuiwon modified.

  • Objectives Although the faith that pulse diagnosis via a thread, namely "Xuanxizhenmai", had been applied to some women in royal families, is widely spread in East Asian countries, but it is still controversial that whether this faith is based on historical facts or just originated from some folk tales. So we provided some reasonable clues to interpret that faith. Methods The digitalized Annals of Joseon Dynasty and Twenty Five Books of Chinese History were used for historical example search. Conventional internet search engines are widely used for investigation of other examples and related interpretations. Additionally, a pilot observation with nylon threads and optical vibration detection devices was performed to confirm it's feasibility. Results Although there are a few evidences supporting Xuanxizhenmai's existence in Qing dynasty, no evidence was found to show it's existence in authoritative annals of Korea and China. The pilot observation showed that in optimal environment, some intense arterial pulse could be propagated dozens of centimeter, but it was not applicable to clinical needs. Conclusions Pulse propagation via a thread was proved to be reproducible within limited extents, but pulse diagnosis via a thread, namely Xuanxizhenmai, seem to have never been used for proper clinical purpose.

  • Objectives : In each section of Huangdineijing, we reviewed how the actual clinical application of Five-Transport-points was reflected and looked at the pattern of the application at the time. Methods : The contents related to Five-Transport-points in Huangdineijing were collected from each part, and analyzed. Results : There was a great difference in the number and contents of the clinical application of each Five-Transport-point for each 12 meridian, and only 28.3% of all Five-Transport-points had been related to clinical treatment. In addition, in specific applications, spring point, stream point, and sea point were used more often than well point, and Five-Transport-points between the same meridian or different meridians were used in combination as needed. Conclusions : Five-Transport-points described in Huangdineijing are intended to be operated within the overall framework structurally or functionally with a certain principle, but as a result of comprehensive analysis of specific examples of clinical application, there was a difference in the application between Five-Transport-points. This indicates that at the time of the establishment of Huangdineijing, which was the early stage of the development of Traditional East Asian Medicine, a variety of miscellaneous acupuncture methodologies were used in addition to those based on five elements principle.

  • Objectives : This study aims to diachronically examine the classification systems of all materia medica, followed by categorization and analysis of each category to deduce each category's characteristic. This will provide foundation for further examining classifications of bencao in contemporary herbology. Methods : Classification systems from a total of 93 bencao related texts were collected and categorized. Each category's classification system was analyzed to determine its meaning. The classification systems were compared from a diachronic perspective, to further deduce each system's problem from a historical context. Results : The classification systems of materia medica could be summarized as following three standards: quality, origin, and medical application. In reality, bencao could be generally classified according to origin and medical application. The origin-based classification system provided a stable and flexible classification outline in the expansion process of bencao. The medical application-based classification strengthened the relationship between bencao and illness pattern, improving clinical applicability. Conclusions : In the history of herbology, the two classification systems created the current of herbology through mutual contribution and conflict. We hope that further discussion on the direction towards which classification system of bencao in contemporary herbology should head will proceed based on this study.

  • The present paper attempts to investigate the factors which may affect the attitude toward Oriental Medicine among the university students in Korea and China. The research on determining factors that may influence the attitude toward the Oriental Medicine can provide the answers for the question how the traditional things can acquire their present position and make a development in modern society. The East Asian countries such as Korea and China have promoted the western-style changes and development, thinking that modernization means the westernization. Given this, the research on the attitude toward Oriental Medicine can be a good case study that shows how tradition sustains its place and develops. The present study makes two hypotheses in order to analyze the factors which make the influence on the attitude toward the Oriental Medicine: Hypothesis there will be no significant difference between the socio-demographic variables and attitude toward Oriental Medicine. Hypothesis there will be significant differences between traditionalism, modernity, nationalism, and attitude toward Oriental Medicine. The statistical results show that hypothesis 1 was confirmed in the case of the gender of the participants, whereas it was not confirmed in the case of the birthplace, economic status, and nationality. And hypothesis 2 was not confirmed in the relations between nationalism and modernity and the attitude toward Oriental Medicine, whereas it was confirmed in the relations between traditionalism and the traditional medical concept and attitude toward Oriental Medicine.
