  • This paper is study on Dong-Eue-Bo-Gam(東醫寶鑑) Dong-Eue-Bo-Gam(單方門)that is written by Heo-Joon. When Heo-Joon worte Dong-Eue-Bo-Gam(東醫寶鑑) between 1596 and 1610, it was the time for the people's healthy to be threatened by all kinds of infections and malnutrition. Dong-Eue-Bo-Gam(東醫寶鑑) compiled Chinese medical books and our medical books that still exists systematically. Especially there was Dan-Bang-Mun(單方門), medical art that is to use only one herb, at the end of each chapter for the people to treat disease. There was Tang-Aek-Pyun the end of Dong-Eue-Bo-Gam(東醫寶鑑). In this part, as it says herbs in rural areas were written in details, it was easy for everyone to get herbs to prevent any disease and to treat their sickness. That's why I'd like to succeed to our senior doctors' spirit for the medicine. So I decided to study Tang-Aek-Pyun that is based on Dan-Bang-Mun in Dong-Eue-Bo-Gam(東醫寶鑑) and many herbs that refer to the 4th of Gang-Je-By-Geup(廣濟秘笈). Medicine that was introduced in Dan-Bang-Mun(單方門) was 860 kinds of medicine. Among them, I choose about 3 kinds of medicine that was used the most frequently.

  • The purpose of this study was to determine the effect of dietary ${\gamma}$-linolenic acid on plasma lipid metabolism and anti thrombotic activity in male Sprague Dwaley Strain rats. Rats weighing an average of $100{\sim}120g$ were fed a experimental diets containing 5% lard (saturated fatty acids), corn oil(linoleic acid), evening promise oil(EPO, 9% ${\gamma}$-linolenic acid) or borage oil(BO, 24% ${\gamma}$-linolenic acid) for 3Odays, respectively. Though there were no significant difference in the food intake among the groups, the body weight gain of the BO group was significantly lower than that of other group. The spleen weight of the lard group was significantly lower than that of other group. The bleeding time of the BO group was significantly longer than that of other group. The blood clotting time was significantly tended to long in EPO and BO groups compared with lard group. The plasma triacylglyceride and total cholesterol concentration were high in order of lard, com oil, EPO and BO, groups and there were significant differences among the groups. The plasma HDL-C concentrations were high in order of BO, EPO, com oil and lard groups and there were significant differences among the groups. The plasma LDL-C concentrations were significantly the highest in lard group, but the lowest in BO group. These data indicate that ${\gamma}$-linolenic acid has a antithrombotic activity, and decrease the plasma triacylglyceride, total cholesterol and LDL-C concentrations in rats.

  • Man-Byeong-Hoi-Chun(萬病回春) is a representative writing of Gong Zhongxian. It was generally used by Koreans in Joseon(朝鮮) era and issued many times in the latter period of Joseon dynasty. We investigated the Jeung-Bo-Man-Byeong-Hoi-Chun (增補萬病回春, An enlarged edition of the Man-Byeong-Hoi-Chun), which is published in the 17th century, coming to a conclusion like the followings. 1. In Joseon(朝鮮), there was the J eung-Bo-Man-Byeong-Hoi-Chun which was made through revision and enlargement of the Man-Byeong-Hoi-Chun written by Gong Zhongxian of China. 2. There are two versions of the Jeung-Bo-Man-Byeong-Hoi-Chun pressed in Joseon, which are written by Kim Yuk(金堉) in 1656 and by Kim Seok-ju(金錫胄) in 1679. 3. The representative medical books of Joseon such as Eui-Rim-Chual-Yo-Sok-J ip (醫林撮要續集), Dong-Eui-Bo-Gam (東醫寶鑑), J e-Jung-Sin-Pyeon(濟衆新編) contained quotations from the J eung-Bo-Man-Byeong-Hoi-Chun(增補萬病回春), not from the Man-Byeong-Hoi-Chun (萬病回春). 4. The Jeung-Bo-Man-Byeong-Hoi-Chun(增補萬病回春) contained not only the essence of the Chinese medicine but also new medical systems reflecting actual circumstances of Joseon at that time. So, it can be recognized as the foundation of the Joseon medicine in the latter period of the dynasty.

  • By studing the congestion theory of Choo Dan-kyei mentioned in "DongEuiBoGam", I have reached following conclusions. 1. Dan-kyei's congestion theory influenced greatly on "DongEuiBoGam". The congestion theory of "DongEuiBoGam" is built up with several theories centering round on Dan-kyei's theory and Huh-Jun's own opinion in addition. 2. Dan-kyei's congestion theory has given theoretical foundation to the classification and diagnosis of congestion reported in "DongEuiBoGam"-Congestion Chapter. 3. Dan-kyei's congestion theory offers many examples of symptoms reported in "DongEuiBoGam"-Congestion Chapter. It's shown well through outer symptoms, several congestion disease, congestion mass, and "congestion never sudden death", etc. 4. Dan-kyei's congestion theory has influenced greatly on treatment of congestion reported in "DongEuiBoGam"-Congestion Chapter, and it's well shown through spewing method, grand method in congestion treatment and common medicine of congestion, etc. 5. Dan-kyei's congestion theory offers variety of treating methods to symptoms caused by congestion reported in "DongEuiBoGam". It's shown variously through upper stomachache, stomachache, back pain, side pain, "San", joint pain, Summer disease, internal injury, cough and morning sickness, etc.. 6. Dan-kyei's congestion theory has factors that could be operated to common diseases of mordern people. They can be classified as food congestion, alcohol congestion, obstruction congestion and Qi congestion, and they are clinically very efficient.

  • The bovine lymphocyte antigen (BoLA)-DRB3 gene encodes cell surface glycoproteins that initiate immune responses by presenting processed antigenic peptides to CD4 T helper cells. DRB3 is the most polymorphic bovine MHC class II gene which encodes the peptide-binding groove. Since different alleles favour the binding of different peptides, DRB3 has been extensively evaluated as a candidate marker for associations with various bovine diseases and immunological traits. For that reason, the genetic diversity of the bovine class II DRB3 locus was investigated by polymerase chain reaction-restriction fragment length polymorphism method (PCR-RFLP). This study describes genetic variability in the BoLA-DRB3 in Iranian Golpayegani Cattle. Iranian Golpayegani Cows (n = 50) were genotyped for bovine lymphocyte antigen (BoLA)-DRB3.2 allele by polymerase chain reaction and restriction fragment length polymorphism method. Bovine DNA was isolated from aliquots of whole blood. A two-step polymerase chain reaction followed by digestion with restriction endonucleases RsaI, HaeIII and BstYI was conducted on the DNA from Iranian Golpayegani Cattle. In the Iranian Golpayegani herd studied, we identified 19 alleles.DRB3.2${\times}$16 had the highest allelic frequency (14%), followed by DRB3.2${\times}$7 (11%). Six alleles (DRB3.2${\times}$25, ${\times}$24, ${\times}$22, ${\times}$20, ${\times}$15, ${\times}$3) had frequencies = 2%. Although additional studies are required to confirm the present findings, our results indicate that exon 2 of the BoLA-DRB3 gene is highly polymorphic in Iranian Golpayegani Cattle.

  • The structural characteristics of 4-coordinate $BO_4$ [B(1)] and 3-coordinate $BO_3$ [B(2)] groups in $BiB_3O_6$ were studied by $^{11}B$ magic angle spinning (MAS) and single-crystal nuclear magnetic resonance (NMR) spectroscopy. The spin-lattice relaxation time in the laboratory frame, $T_1$, for $^{11}B$ decreased slowly with increasing temperature, whereas the spin-lattice relaxation times in the rotating frame, $T_{1{\rho}}$, for B(1) and B(2), which differed from $T_1$, were nearly constant. Further, $T_{1{\rho}}$ for B(1) and B(2) showed very similar trends, although the $T_{1{\rho}}$ value of B(2) was shorter than that of B(1). The 3-coordinate $BO_3$ and 4-coordinate $BO_4$ were distinguished by $^{11}B$ MAS NMR spectrum and $T_{1{\rho}}$.
