${\ulcorner}$Ilbonseogi${\lrcorner}$(edited A.D. 720) )was studied to investagate the medical and pharmaceutical exchange among ancient Korea, China and Japan. It seemed that Korean and Chinese traditional medicine was introduced to Japan through Korea. It was also shown in ${\ulcorner}$Ilbonseogi${\lrcorner}$ that Koreans who lived in china and Japan during that time seemed to hove active medical idea exchange. From various facts indicated in ${\ulcorner}$Ilbonseogi${\lrcorner}$, it was believed that Korean and Chinese traditional medicine was the basis for the foundation of Japanese traditional medicine.

Total ginsenosides were purified and their antioxidant, antibacterial and anticancer activities were measured. The crude extracts of ginseng, which were extracted with 75% ethanol by ultrasonification method, were firstly purified on AB-8 macroporous adsorption column to remove water soluble impurities, and decolored on Amberlite IRA 900 Cl anion-exchange column. Then, they were purified on Amberlite XAD16 adsorption column to delete the non-polar impurities. Total ginsenosides contents of the purified extracts were 79.4%, 71.7% and 72.5% in cultured wild ginseng, red ginseng and white ginseng, which were significantly increased than those of crude extracts. All of the three extracts showed concentration-dependant scavenging activities against DPPH radicals, among which white ginseng showed the most powerful activity. Cultured wild ginseng roots showed strongest effect against both B. subtilis PM 125(Gram-positive) and E. coli D31 (Gram-negative) bacteria, while red ginseng and white ginseng only showed the activity against B. subtilis. According to the result of the MTT assay, ail of the three extracts inhibited the growth of U-937 human hohistiocytic lympma cell, which were significantly different (p < 0.05) when compared to the control.

This study was aimed (i) to develop an effective method for the purification of ginsenosides for industrial use and (ii) to compare the distribution of ginsenosides in cultured wild ginseng roots (adventitious root culture of Panax ginseng) with those of red ginseng (steamed ginseng) and white ginseng (air-dried ginseng). The crude extracts of cultured wild ginseng roots, red ginseng, and white ginseng were obtained by using a 75% ethanol extraction combined with ultrasonication. This was followed sequentially by AB-8 macroporous adsorption chromatography, Amberlite IRA 900 Cl anion-exchange chromatography, and Amberlite XAD16 adsorption chromatography for further purification. The contents of total ginsenosides were increased from 4.1%, 12.1%, and 11.3% in the crude extracts of cultured wild ginseng roots, red ginseng, and white ginseng to 79.4%, 71.7%, and 72.5% in the final products, respectively. HPLC analysis demonstrated that ginsenosides in cultured wild ginseng roots were distributed in a different ratio compared with red ginseng and white ginseng.

Flavonoids with oxygen atoms are known to have potent biological effect.They have been studied long as major antioxidants which protect cell membranes. Recent medical surveys show that increased intake of selenium decreases the risk of breast, colon, lung and prostrate cancer by preventing free radical generation. The flavonoids, isoflavonoids, and coumarins which form the bulk of these compounds are very polar and have limited use as drugs which have to pass through BBB(Brain Blood Barrier)The non-polar property is increased by exchange oxygen to selenium as a part of heterocyclic compound.

With the Sunshine policy. exchange of goods and cultures inter Koreas is broaden and expectancy of reunification is getting higher. Especially. medical supplies and medicines is one of the biggest parts in the exchanges. So. need for preparing new medical administration system for reunification is needed. We are going to compare inter Koreas drug administration system in medical services. (omitted)

With the Sunshine policy, exchange of materials and cultures inter Koreas has been broadened and expectancy of reunification is getting higher. Especially, medical supplies and medicines are one of the biggest parts in the exchange goods. So, preparing an unified official drug standard preparing new medical administration system is required. We compared the Korean pharmacopoeia with North Korean Pharmacopoeia. Two pharmacopoeias have been developed in different direction and have many differences in the nomenclature and format. In this study, we compared general notices, general rules for preparations and crude drugs, monographs, general tests, processes and apparatus.

Objectives : The aim of this study was to investigate the effect of various Republic of Korea policies, including the medicine cost rationalization policy implemented By investigating the management strategy/performance changes of the industry caused by such policies. Methods : Pharmaceutical companies listed on the national stock exchange and the KOSDAQ were examined for 10 years from 2004 to 2013. Their financial statements were collected and market changes before and after drug price policy implementations were compared. Results : From the result of this research, among the medicine related policies, the drug price rationalization policy was found to have a significant effect on business management strategies in terms of safety, profitability and growth potential after its implementation. After the drug pricing transparency policy was implemented, management strategies were affected significantly in terms of safety and profitability. Conclusions : As a result, all of the medicine related policies were found to have regulatory effects. Based on these findings, implications, research limitations and future study plans are presented.

This study was performed to investigate the supply and demand of the oriental medical doctor(OMD) based on the supply and demand analysis of OMD up to the year 1997. The baseline projection and demographic methods were considered to examine the supply of OMD. On the contrary, for the demand analysis, two different approaches were conducted with the nonlinear regression model. The findings of this study indicate that the OMD will be oversupplied before the year 2012 with decreasing rate. However, when we consider the demand of OMD in the future. it is anticipated that the demand of oriental medicine will be increased rapidly with two major aspects. The first is the expansion of insurance benefits. The second is the increasing number of adult diseases because of the aging of the population structure. Therefore, the effective cooperation system and mutual exchange between western and oriental medicine is required for the future. Also. it is necessary to make the oriental medicine of the pharmaceutical services in more scientific way for the appropriate policy of the demand and supply of OMD. For the future study, the students who study abroad, especially China should be considered. These students will be the key element for the future supply of OMD.

The purpose of this study is to assess how accounting conservatism is practiced in the Jordanian pharmaceuticals and medical industry. It assesses the association between accounting conservatism and intellectual capital (IC) in this industry. This study measures IC performance using the market price per share less book value. Accounting conservatism is measured using the book-to-price ratio, and the data was collected from company annual reports and the Amman Stock Exchange (ASE) website. The data was collected for the period of six years (2014 to 2019). The sample was made up of four companies in the industry listed in the ASE. The data was analyzed using the SPSS program though the ordinary least squares regression model to assess how accounting conservatism is associated with IC. The findings indicate a negative association with companies having higher IC performance and reporting lower accounting conservatism. IC is applied more in these companies, although it might be lower than in other companies in other sectors. This study provides empirical evidence on how IC is applied in the industry and how it might be negatively associated with accounting conservatism. Findings indicate the need for more effective policies to promote recognition of intangible assets in the sector.

원지(Polygala tenuifolia, Polygalaceae)에 함유되어 있는 ${\beta}$-carboline계의 알칼로이드를 HPLC를 이용하여 정량하는 방법을 검토하였다. 고정상으로는 RP-18 컬럼을 사용하였고, 이동상으로는 $CH_3CN$과 0.01M 인산완충액(pH=3.5)을 기울기 용리시켰으며, UV254nm에서 검출하였다. 알칼로이드 분획을 얻기 위한 전처리 방법으로 산, 염기 처리에 의한 용매추출법과 양이온교환수지(Amberlyst 15)를 이용한 고상추출법을 비교한 결과 양이온 교환수지를 이용한 방법에서 더 나은 크로마토그램을 얻을 수 있었으며, 정량 결과 원지 중 알칼로이드 함량은 각각 harman $2.8{\times}10^{-3}%$, norharman $1.7{\times}10^{-3}%$, 1-carbomethoxy-${\beta}$-carboline $1.3{\times}10^{-3}%$, 1-carboethoxy-${\beta}$-carboline $1.4{\times}10^{-3}%$, perlolyrine $3.3{\times}10^{-3}%$로 나타났다.
