  • The objective of this paper is to examine what impact the newly introduced Purchasing Price Reimbursement System, where insurance drugs are reimbursed at the prices as they were purchased by medical care providers under the maximum allowable cap, has upon the health insurer's financing situation. The impact of the Purchasing Price Reimbursement System is considered to be confined mainly to the inpatient department among three drug reimbursement fields such as inpatient department, out-patient department and pharmacy. Hypothesis was set and tested in this study for each of three components of inpatient drug reimbursement in health insurance, i.e. average price level, composition of drugs and their overall volume. Drug price level calculated in this study from 403 selected reimbursement drugs according to the Laspayres methodology revealed faster decline under the new Purchasing Price Reimbursement System than previously by $1.53\%$ on the annual average basis. However, additional 1.4 percent financial burden in the ratio of the total inpatient reimbursement was owed by the health insurer. This was analysed to be a combined result of both 2.0-3.1 percent of reduced reimbursement due to drug price decline and 3.4-4.5 percent of additional reimbursement due to drug volume increase. These results suggest that recalling the Purchasing Price Reimbursement System would not have so much impact upon the health insurer's financial situation given that the current compulsory separation between doctor's prescribing and pharmacist's dispensing is irrevocable.

  • An attempt was made to investigate free and bound lipid contents and fatty acid compositions of ginseng and its eveven kinds related crude drugs. Contents of free and bound lipids of ginseng were 1.23% and 0.47%, and those of the related crude drugs were $0.31{\sim}13.05%$ and $0.26respectively. Fourteen even-numbered and 4 odd-numbered fatty acids were identified by GLC in those lipids from ginseng, and the major fatty acids were linoleic, palmitic, oleic and linolenic acids. The crude drugs are notably different from ginseng in kinds and compositions of fatty acids of free and bound lipids. Composition ratios of unsaturated fatty acids were higher in free lipids from ginseng than those of the crude drugs except 'Won-ji' Polygalae Radix.

  • Sokmyeungtang was the representative prescription for Apoplexy under the rule of Tang and Song dynasty of which the cultures were thriving in the history of China. However, the clinical use of Sokmyeungtang has been gradually reduced since Geumwon dynasty of China because it was misunderstood that the dryness heat drugs of pungent in flavor and warm in property such as Ephedra, Pubescent Angelica Root, Chinese Cassia Tree-Bark, Divaricate Saposhnikovia Root, Prepared Aconite Root, Fresh Ginger, and Wildginger Herb included in the presciption for Apoplexy supplemented heat as damaging Yin flood. In fact, the drugs pungent in flavor and warm in property activate exterior and interior circulation, circulate channels and collaterals, promote blood circulation, and remove blood stasis with the side effect of relieving exterior syndrome with drugs warming channels. When treating Apoplexy with Sokmyeungtang, the cold drugs such as Gypsum, Baikai Skullcap Root, and Pueraria Root are prescribed to suppress fire of pungent dryness and to control excessive heat of people with Apoplexy as reducing the effects of hot drugs causing impairment of Yin. For treatment of Apoplexy, the above drugs accelerate blood and Qi circulation in channels and collaterals and then in necrotic tissue of human body as removing blood stasis. Consequently, these drugs improve disorders of capillary tube circulation. If Sokmyeungtang, an old prescription, is properly understood, it will be substantially helpful to all kinds of treatments in clinical cases

  • The aim of the present study was to investigate the various chemical components present in the cone volatile oil of Cupressus macrocarpa and also determine its antimicrobial activity. Totally 13 compounds were identified with 99.99% by GC-MS analysis. The major compounds identified were terpinene-4-ol (19.42%), dinopol (15.63%), ${\alpha}$-pinene (13.58%), and ${\beta}$-pinene (12.16%). The antimicrobial activity was carried out for the oil and a 2% cream formulation using cup plate method by measuring the zone of inhibition. The gram positive organisms used were Bacillus subtilis, Staphylococcus aureus, Bacillus megaterium, and Bacillus cogulans. The gram negative organisms used were Escherichia coli, Kleibseilla pneumonia, Pseudomonas aeruginosa and Salmonella typhi. In vitro antifungal studies were also carried out by using organisms, Candida albicans, Aspergillus flavus, Trichoderma lignorum and Cryptococcus neoformans. The standard drugs used were penicillin ($100{\mu}g/mL$), gentamycin ($100{\mu}g/mL$) and griseofulvin ($100{\mu}g/mL$) for gram positive bacteria, gram negative bacteria and fungi respectively. Both oil and cream formulation showed good activity against fungi than bacteria. This study is being reported for the first time on cone volatile oil of this plant.

  • Three hundred sixty-two(male 131, female 231) elderly aged over 65 in Chungb- uk area were interviewed to determine the disease states and drug usage patterns. The prebalence of disease was 78% and women reported more chronic diseases(83%) than men(71%). Elderly who live with spouse and have an occupation have a lower rate of disease. Average number of diseases of the elderly was $1.8\pm{1.1}$, and women$(2.1\pm{1.3)}$ have significantly higher average number of diseases than that of men$(1.4\pm{0.7)}$. Also the elderly in urban areas$(2.1\pm{1.4)}$ have significantly higher number of diseases than that of the elderly in rural areas$(1.6\pm{0.9)}$. Arthritis, hypertension, cardiovascular and gastric diseases were the most frequently listed chronic diseases in order for both men and women. Anemia and fracture of bone were relatively higher in women than in men. Particularly, the arthritis of the urban elderly have a rate of 1.5 times higher than that of the rural elderly. Fifty-two percent of the elderly were currently using drugs ; among drug users 71.2% used prescription drugs and 20.5% used nonprescription drugs. The average number taken per person was 2.1$\pm$1.4 and there was no sex or age difference. However, the elderly in rural areas $(2.7\pm{1.7)}$ consumed a significantly higher number of drugs than those in urban areas$(1.7\pm{0.7)}$. The average number of prescripti- on drugs taken was 2.0$\pm$1.4 while the average of nonprescription drugs taken was $(1.3\pm{0.6)}$. Analgesics and antihypertensive drugs were most commonly used. Vitamin and analgesics were the most frequently used self-prescribed drugs. It was noted that potential adverse drug interaction by concominant drug consumption for arthritis and antihypensive drug, abuse of digestants and antiacid without treatment of the underlying disease, and misuse of quick-acting bowel medications were problematic for the elderly. In addition drugs used for the elderly have some adverse effect on the digestive system. The types and composition of drugs used by the elderly were identified and presented. Medication compliance was poor and 13.5% reported adverse reactions such as edema, heartburn, nausea, and difficulty with eating. Seventeen percent of the elderly obtained drugs arranged by those other than medical staff. Also, even among those elderly who obtained drugs prescribed by a doctor, 69.1% of subjects had not receive instruction about potential adverse reactions. These results suggest that nutritional problems related to drug usage might exist and so dietitians, either individually or as members of health teams, need to have a better understanding of drug-nutrient interaction and closer supervision, and drug information/education service should therefore be provided to prevent or minimize adverse drug reaction in elderly users of medication.

  • Objectives : The purpose of this study was to analyze and identify the problems of the changes in regulations that are relevant to approval, notification, and review of herbal medicinal preparations and crude drug preparations. Methods : I collected the regulations of approval, notification, and review of medicinal products mostly from official gazettes, analyzed enactment and amendments regarding herbal medicinal preparations and crude drug preparations, and studied it from the view point of Korean medicine field. Results : Regulations in regards to approval, notification, and review of herbal medicinal preparations and crude drug preparations were first established in 1978. Herbal drugs started to be categorized as crude drug preparations in 1981 and the regulatory outlines were completed in 1999. From 2008 to 2012, the regulatory standards that let crude drug preparations be new drugs from natural products were established. Through those procedures, the followings became crude drug preparations: 1) wholly new prescriptions that are not recorded in Korean Medical Classics, 2) prescriptions that are recorded in Korean Medical classics but prepared with new standard, composition and efficacy, 3) prescriptions that are recorded in Korean Medical classics but prepared with new formulation, and 4) herbal drugs. In case of herbal medicinal preparations, however, only regulations that are related to 1) drugs prepared with new compositions that are not recorded in Korean Medical Classics, 2) drugs with same prescription and same formulation, and 3) drugs with new formulation were arranged. Conclusions : Actual circumstances on crude drug-oriented regulations regarding approval, notification and review and future forms of prescription and drug administration in Korean Medical Institutions can be expected due to expansion in range of herbal medicinal preparations and shrink in that of on-site preparations. Reasonable improvement in efficient usage of modernized herbal medicinal preparations in Korean medical institutions and prospective cooperation from related pharmaceutical industry are needed.
