식물성장 촉진 기능을 가지는 PGPR (plant growth-promoting rhizobacteria)균은 특수한 토양시료를 사용하여 내열성을 가지는 400개의 균주를 분리하였다. 이들 분리균주에서 선발한 공시균주 Bacillus sp. YK-5는 항진균성 물질을 생산하였으며, 시험균주 Asp. flavus를 대상으로 생산조건을 검토한 결과, 공시균주의 생육배지는 생육촉진효과와 식물병원균에 대한 방제를 위해 1% peptone 및 yeast extract, 5% black sugar가 함유된 modified LB배지를 사용하였다. 식물병원균에 대한 공시균주의 길항효과는 시험균주인 식물병원균 Fusarium oxysporum KACC 40052균에 대해 배양 7일째까지 강한 생육저해를 보였다. 공시균의 식물성장촉진능은 궁중무 및 벼를 대상으로 pot 실험한 결과, 궁중무의 경우 경엽수, 줄기의 길이 및 뿌리의 길이가 무처리구에 비해 약 60%이상 우수한 성장촉진효과를 나타내었으며, 벼의 경우 이식 후 시비 8일째 시판제품 처리구에 비해 공시균주 처리구는 잎의 길이와 흰 세근의 발달이 우수하여 뿌리의 발육에 현저한 생육촉진 효과를 나타내었다. 공시균주의 동정은 분자계통분류학적 분석 (형태, 배양, 생리, 화학적 및 분자생태학적 측면)에 의해 B. subtilis YK-5로 명명하였다.

본 연구는 4년근 산양삼을 4년 숙성된 감식초에 22주간 혼입숙성하여 만든 산양삼감식초(가칭: 산삼초)를 활용하여 식이제한을 하였을 때 나타나는 비만관련 요소들을 분석하였다. 웅성 흰쥐 63마리를 대상으로 고지방식을 공급하면서 식후 2회, 6주간 산삼초를 경구투여하였다. 집단은 대조군, 제한식이군, 웨이트사이클링군으로 구분하였으며, 이를 다시 대조군, 산삼초 2.5배 희석 섭취군, 산삼초 5.0배 희석 섭취군으로 각각 구분하였다. 각 집단은 7마리씩으로 하였다. 6주간의 사육이 종료된 후, 복강내 지방(복막후지방, 장간막지방, 부고환지방)과 대사관련 단백질(AMPK, PPAR-${\alpha}$, CPT-1)의 발현을 분석하였다. 결과를 볼 때, 모든 집단에서 산삼초 섭취에 의한 지방저장량의 유의한 감소 또는 감소 경향이 나타났으며, 지방저장량의 총합계 역시 산삼초 섭취에 의해 증가가 억제되었다. 이와는 반대로 대사관련 단백질 발현은 모든 항목에서 산삼초 섭취에 의해 유의한 증가 혹은 증가 경향이 나타났다. 이 결과는 산삼초 섭취에 의한 에너지 대사의 효과적인 상승이 고지방식이 또는 식이제한을 하였을 경우에도 체내 지방 저장량의 증가를 억제하였다는 것이다. 즉, 비만의 가장 큰 문제점인 웨이트사이클링의 억제를 위한 좋은 기능성을 보유하고 있다고 판단된다. 이를 통하여 임업산물인 산양삼과 감식초의 융합소재인 산삼초를 비만억제 식품으로 활용할 수 있을 것으로 기대된다.

One's constitution is formed congenitally and is also acquired, and is relatively stable in its individually manifested function, structure and temperament. It has characteristics of universality, complexity, generality and continuity. It is also manifested in physiological responses and expresses pathologic tendencies including susceptibility. Attempts at understanding constitution has had a long history throughout the world. In Oriental Medicine, the constitution had been acknowledged from the "Huangdi Neijing", which has been a bible in Oriental Medicine for about two thousand years. In many aspects, the "Huangdi Neijing" provides the basis for both basic and practical fields. In order to derive the ideal structure from the "Huangdi Neijing" to Lee Je-ma's(Lee Jayma's) Sasang Constitutional ideas, which can strengthen the understanding of ideal core of Oriental Medicine's constitutional characteristics, the author launched his analysis of the constitutional understandings in the "Huangdi Neijing" as a first step and came to the following: 1. The constitutional understanding in the "Huangdi Neijing" was done both via the physiological responses to heat, pain and acupuncture treatment and the pathologic tendencies via body structure, strength, body heat, courage and obesity. 2. It was recognized that the constitution was formed congenitally and also acquired factors like living conditions including food customs, residents and geographical conditions were explained in detailed. 3. The constitutional typology was suggested both by the general and systematic criterion according to the Yin-yang and the Five phase theories and by single criterion such as obesity, courage and the response to acupuncture treatment. 4. As diagnosis is related to the constitution, courage was adopted for the disease caused by emotions, obesity was for its manifestations of qi and blood, the quantities of qi-blood and Yin-yang in the typology by the Yin-yang and Five phase theories were suggested. 5. In the case of obesity, Yin-yang and Five phase theory, treatment according to the constitutional ideas was mentioned, and their goals were concluded as "being the balancing between Yin and Yang" which means the Yin-yang theory is more practical than the Five phase theory in Oriental Constitutional Medical field. According to the above understandings, the author would like to suggest that the constitutional ideas in the "Huangdi Neijing" based on the Yin-yang theory blossomed via the practical spirit of Zhang Zhong-jing's "Shanghanlun" and at last from Lee Je-ma's(Lee Jayma's) Sasang Constitutional Medicine which realized "the balancing between Yin and yang" through the practical applications of herbal treatments.

The existing Extracorporeal membrane oxygenation(ECMO) and Cardiopulmonary bypass system(CPB) have been developed and applied to various devices according to their respective indications. However, due to the complicated configuration and difficult usage method, it causes inconvenience to users and there is a risk of an accident. Therefore, smart all-in-one cardiopulmonary circulation device is being developed recently. The smart all-in-one cardiopulmonary assist device consists of a blood pump for cardiopulmonary bypass, a blood oxidizer for cardiopulmonary bypass, a blood circuit for cardiopulmonary bypass, and an artificial cardiopulmonary device. It is an integrated cardiopulmonary bypass device that can be used for a variety of purposes such as emergency, intraoperative, post-operative intensive care, and long-term cardiopulmonary assist, combined with CPB used in open heart surgery and ECMO used when patient's cardiopulmonary function does not work normally. The smart all-in-one cardiopulmonary assist device does not exist as a standard and international standard applicable to advanced medical devices. Therefore, in this study, we will refer to the International Standard for Blood Components, the International Standard for Blood, the Guideline for Blood Products, and prepare applicable performance and safety guidelines to help quality control of medical devices, and contribute to the improvement of the health of people. The guideline, which is the result of conducted a survey of the method of safety and performance test, is based on the principle of all-in-one cardiopulmonary aiding device, related domestic foreign standards, the status of domestic and foreign patents, related literature, blood pump(ISO 18242), blood oxygenator (ISO 7199), and blood circuit (ISO 15676) for cardiopulmonary bypass.The items on blood safety are as follows: American Society for Testing and Materials ASTM F1841-97R17), and in the 2010 Food and Drug Administration's Safety Assessment Guidelines for Medical Assisted Circulatory Devices. In addition, after reviewing the guidelines drawn up through expert consultation bodies including manufacturers / importers, testing inspectors, academia, etc. the final guideline was established through revision and supplementation process. Therefore, we propose guidelines for evaluating the safety and performance of smart all-in-one cardiopulmonary assist devices in line with growing technology.

Objective: Fibronectin 3 (FN3) and immunoglobulin like modules (Ig) are usually collocated beside modular cellulase catalytic domains. However, very few researches have investigated the role of these modules. In a previous study, we have sequenced and analyzed bacterial metagenomic DNA in Vietnamese goats' rumen and found that cellulase-producing bacteria and cellulase families were dominant. In this study, the properties of modular cellulases and the role of a FN3 in unique endoglucanase belonging to glycosyl hydorlase (GH) family 5 were determined. Methods: Based on Pfam analysis, the cellulases sequences containing FN3, Ig modules were extracted from 297 complete open reading frames (ORFs). The alkaline, thermostability, tertiary structure of deduced enzymes were predicted by AcalPred, TBI software, Phyre2 and Swiss models. Then, whole and truncated forms of a selected gene were expressed in Escherichia coli and purified by His-tag affinity column for assessment of FN3 ability to enhance enzyme activity, solubility and conformation. Results: From 297 complete ORFs coding for cellulases, 148 sequences containing FN3, Ig were identified. Mostly FN3 appeared in 90.9% beta-glucosidases belonging to glycosyl hydrolase family 3 (GH3) and situated downstream of catalytic domains. The Ig was found upstream of 100% endoglucanase GH9. Rarely FN3 was seen to be situated downstream of X domain and upstream of catalytic domain endoglucanase GH5. Whole enzyme (called XFN3GH5 based on modular structure) and truncate forms FN3, XFN3, FN3GH5, GH5 were cloned in pET22b (+) and pET22SUMO to be expressed in single and fusion forms with a small ubiquitin-related modifier partner (S). The FN3, SFN3 increased GH5 solubility in FN3GH5, SFN3GH5. The SFN3 partly served for GH5 conformation in SFN3GH5, increased modules interaction and enzyme-soluble substrate affinity to enhance SXFN3GH5, SFN3GH5 activities in mixtures. Both SFN3 and SXFN3 did not anchor enzyme on filter paper but exfoliate and separate cellulose chains on filter paper for enzyme hydrolysis. Conclusion: Based on these findings, the presence of FN3 module in certain cellulases was confirmed and it assisted for enzyme conformation and activity in both soluble and insoluble substrate.

CD47 (integrin-associated protein), a multi-spanning transmembrane protein expressed in all cells including red blood cells (RBCs) and leukocytes, interacts with signal regulatory protein ${\alpha}$ ($SIRP{\alpha}$) on macrophages and thereby inhibits phagocytosis of RBCs. Recently, we generated a novel C57BL/6J CD47 knockout ($CD47^{-/-}$ hereafter) mouse line by employing a CRISPR/Cas9 system at Center for Mouse Models of Human Disease, and here report their hematological phenotypes. On monitoring their birth and development, $CD47^{-/-}$ mice were born viable with a natural male-to-female sex ratio and normally developed from birth through puberty to adulthood without noticeable changes in growth, food/water intake compared to their age and sex-matched wild-type littermates up to 26 weeks. Hematological analysis revealed a mild but significant reduction of RBC counts and hemoglobin in 16 week-old male $CD47^{-/-}$ mice which were aggravated at the age of 26 weeks with increased reticulocyte counts and mean corpuscular volume (MCV), suggesting hemolytic anemia. Interestingly, anemia in female $CD47^{-/-}$ mice became evident at 26 weeks, but splenomegaly was identified in both genders of $CD47^{-/-}$ mice from the age of 16 weeks, consistent with development of hemolytic anemia. Additionally, helper and cytotoxic T cell populations were considerably reduced in the spleen, but not in thymus, of $CD47^{-/-}$ mice, suggesting a crucial role of CD47 in proliferation of T cells. Collectively, these findings indicate that our $CD47^{-/-}$ mice have progressive hemolytic anemia and splenic depletion of mature T cell populations and therefore may be useful as an in vivo model to study the function of CD47.
