In the course of searching for acetylcholinesterase inhibitors from crude drugs, it was found that total MeOH extract of Corydalis Tuber showed significant inhibitory effect on acetylcholinesterase. To isolate acetylcholinesterase inhibitors from Corydalis Tuber, total MeOH extract of the the crude drug was subjected to activity guided fractionation. The MeOH extract was suspended in water and fractionated with methylene chloride and subjected to acid-base fractionation. Silica gel column chromatography of the basic fraction which showed significant inhibitory effect on acetylcholinesterase was carried out and 5 subfractions (1-5) were obtained. From subtraction 4, compound I was isolated. The structure of isolated compound I was identified by spectroscopic parameters of $^1H-NMR$, $^{13}C-NMR$, EI-MS and FAB-MS. The compound I was identified as berberine. It was found from the Lineweaver-Burk plot that berberine was a reversible and specific inhibitor of acetylcholinesterase having 90% inhibitory effect at the concentration of $2.5{\mu}M$.

It has been 2 years since the implementation of the separation of prescription and drug dispensing policy. This study analyzes the effects of the policy on the job contents and personnel structure of hospital pharmacy. The main purposes of the analysis are to determine if the policy has causes the increase of professional activities of pharmacists in hospital and to investigate whether the hospital pharmacy is equipped with enough manpower to provide high quality pharmaceutical service as intended by the policy. The level of professionality of pharmacists' activities is measured by the number of activities of direct involvement in inpatient care such as participation in patient rounding, medication consultation, the number of hospital committee the pharmacists involved and the number of continuous education pharmacists took. The adequacy of personnel structure to provide high quality pharmaceutical care is measured by the level of compliance to the governmental standard of hospital pharmacy personnel. In order to collect the data, surveys were performed for two periods: year 1999 (before the implementation of the policy) and year 2001 (after the implementation of the policy). The results show that the pharmacists' participation in inpatient rounding decreased and that the inpatient medication history management activities, operation of ward pharmacy, participation in hospital committee increased. In personnel structure, the average number of pharmacist per hospital decreased and the number of prescription processing per pharmacist increased. Based on the results this study concludes that the professional activities of hospital pharmacists has increased a little and there were structural changes in hospital pharmacy service activities to increase the professionalism in providing care. However, the pharmacy departments were understaffed hampering the strive to increase the provision of professional pharmaceutical service in hospitals.

It has been 2 years since the implementation of the separation policy of drug prescription and dispensing. This study analyzes the changes in community pharmacy operation after the implementation of the policy. The main purposes of the analysis are to determine whether the changes in community pharmacy operation have occurred and to evaluate that the changes are consistent with the intention of the policy, if the changes actually have occurred. For the study a survey on 961 pharmacies chosen by stratified sampling method has been performed. Of the 961 sample pharmacies, 438 pharmacies were responded resulting 45.6% response rate. The sample pharmacies are classified by the location that the pharmacy are operating: the pharmacies around large size hospitals, the pharmacies around clinics or medium to small size hospitals and the pharmacies with no hospitals or clinics around. Based on the classification, the number of pharmacies, number of prescriptions processed, the personnel structure, the changes in facility, and other operational characteristics are compared. The results showed that the pharmacies were tended to concentrate around hospitals and clinic since the implementation of the policy. The number of pharmacists per pharmacy was increased, the size of pharmacy was increased and the facilities were improved to accomodate the requirements of the policy. The work hours a pharmacist spent on dispensing drug have increased almost twice, however, there was no corresponding increase in the time spent on patient education and medication history management, indicating a problem in the provision of quality pharmaceutical services. Based on the results, suggestions to minimize the negative effects of the policy are provided.

The neurotoxicity induced by L-glutamate in primary cultures of rat cortical cells could be attenuated by diterpene constituents of Ginkgo biloba leaves, ginkgolides A, B and C. At the concentration of 100 nM, ginkgolides up-regulated the activity of glutathione reductase in primary cultures of rat cortical cells exposed to 100 ${\mu}$M glutamate. Furthermore, ginkgolides increased the content of reduced glutathione in glutamate-treated cortical cells. However, ginkgolides showed little effect in reducing superoxide dismutase activity. Ginkgolides did, however, markedly block the production of malondialdehyde, a byproduct of lipid peroxidation in glutamate-treated rat cortical cells.

Five phase theory has significant effect on Traditional Chinese Medicine, which puts its emphasis on correlation and integrity. However, the five phase theory itself has a limitation that it cannot reflect the general correlation and special features of affairs. Traditional Chinese Medicine pertains the five organs to five elements, absorbing the essence of the five phase theory, and transcending the limitation of the five phase theory in practice. Therefore, Traditional Chinese Medicine and other traditional medicine theories can be called as "five viscera correlation theory". On the course of modernization of traditional medicine, the effects among the five viscera can be concluded to 3 correlations of promotion, coordination and inhibition, to illustrate the integrity and correlation theory of traditional medicine from different approaches.

This study is intended to provide information to menopausal women so they can control their symptoms. The basic data was gathered by interviewed 200 postmenopausal women on a HRT program. The women were questioned about their perception of menopause and compliance to the therapy with the fellowing result $71.7\%$ of the women experianced hot flushes, and $64.1\%$ experienced short term memory loss and some psychological symptoms. The women reported that these symptoms reduced their quality of life. $53\%$ of the women responded that menopause is a natural state and $59.1\%$ agreed to HRT based on their doctor's recommendation. $76.2\%$ of the women reported that HRT was effective, with $74.7\%$ reporting reduced hot flush symptoms $67.3\%$ of the women reported compliance with the medication schedule. and $43.9\%$ reported periodic non-compliance. Although HRT has been shown to be an effective treatment, the study found that less than $10\%$ of postmenopausal women are currently being treated and these treated women are generally negligent in continuing with HRT, The study recommends that a program be developed that explains the benefits and risks of HRT to be distributed to patients being treated by doctors and pharmacists. In conclusions, It is very important for hormone replacement therapy on menopausal women to take more intensive medication consultation to increase medication compliance and effectiveness of pharmacotherapy.

This study intended to investigate the pediatric drug dispensing practice at hospital pharmacies in order to provide the children with proper pharmaceutical care services. According to the study results, the most significant problem in dispensing pediatric drugs was that only a few pediatric drugs were supplied by the pharmaceutical companies in Korea. It was found that pediatric drugs like rifampicin, phenobarbital and theophylline should be produced in the form of syrup or powder, for the children to swallow drugs with ease. The study results also showed that only $35.5\%$ of the hospital pharmacists reviewed all the prescriptions issued by doctors. In most cases $(65.3\%)$ drug information was only provided when the patients asked to the pharmacists. The lack of working time and clinical information on the patients were found as major barriers. Thus in order to provide better pharmaceutical care services for the children, not only the pharmaceutical companies should pay attention to the production of pediatric drugs, but pharmacists should make every efforts on playing patient-oriented roles.

Objectives: Agent Orange TCDD has been related to serious diseases among Korean veterans who were exposed to it. Decades after the end of the war, however, its effects are still being debated. The object of this study was to examine various unmet needs raised among Agent Orange exposed veterans and their families and to find grounds of a new welfare policy for providing alternative legislation. Methods: Literatures concerning Agent Orange, TCDD, the associated diseases, compensation for veterans and Supreme Court sentencing were searched using PubMed, ProQuest, press news and relevant homepages. Results: Agent Orange exposed veterans are eligible for various benefits from the government, including disability compensation for diseases associated with exposure. The Ministry of Patriots and Veterans Affairs has classified certain diseases into two categories, Agent Orange sequela diseases and sequela suspect diseases and has provided differential benefits based on separated laws. Big differences exist in benefits to veterans and their families between the two laws. The absence of definite standards to classify the Agent Orange associated diseases was confirmed by recent Supreme Court sentencing which ruled in favor of US manufacturers. Conclusion: It appears that the evidence for cause and effect of Agent Orange related diseases would never be perfect. The results suggest a need to change welfare principles from presumptive or indefinite disease basis to exposure experiences combined with integrated disability evaluation. We propose to extend eligibility by enacting a new law for Agent Orange exposed Korean veterans.
