In the course of search antagonistic fungi from soil in green house, four kind of fungi (AF1, AF2, AF3, AF4) were isolated, which have activities against Phytophthora capsici, Botrytis cinera, Rhizoctonia solani, Pythium ultimum and Fusarium oxysporum. The AF2 was identified according to the morphological description of Aspergillus terreus. This antagonistic fungus inhibiting various plant pathogens was effective to reduce disease incidence of cucumber seedlings caused by mixed inoculum of Rhizoctonia solani, Pythium ultimum and Fusarium oxysporum. Antifungal compound I was isolated and purified by fresh chromatography from A. terreus. The $^1H$ and $^{13}C$ assignment of compound I was achieved from two-dimensional $^1H-^1H\;COSY$, HMQC, HMBC with the add of homonuclear and heteronuclear double resonance experiment. The compound I was identified butyrolactone I (${\alpha}$-oxo-${\beta}$-(p-hydroxyphenyl)-${\gamma}$-(p-hydroxy-m-3,3-dimethyl-allylbenzyl)-${\gamma}$-methoxycarbonyl-${\gamma}$-butyrolactone, $C_{24}H_{24}O_7$, M.W.=424).

Nowaday, beyond the time of wellbeing and LOHAS, many people have great interest in self therapy, so it is called healing era. As the folk medicine fields are actively industrialized and the interest in health improvement, not disease cure, is increased, many researches about the alternative medicine and therapy in various fields are being performed. In the times of the interest in health improvement and spontaneous, natural healing ability of human body is getting increase, it is very meaningful to search the factors which consist of recognition to folk medicine. So in this study, we developed the questionaries on the basis of previous studies, researched the factors affecting the recognition to folk medicine using factor analysis, and tested statistically the difference of recognition character according to demo-statistical traits. As the result, the twenty-four measurable variables related to folk medicine are sorted to four factors, ie, health improvement factor, safety factor, psycholocial factor, and substitutional factor. And overall, the middle and senior ages, the forties to sixties, and higher-educated peoples have more experiences in folk medicine than the younger ages, below thirties and lower-educated peoples. The distiction of sex makes little differences.

35 theses conducted in Korea on the topic of senescence or anti-oxidant were classified on the basis of research methods, animals used for the experiments, and research items. Evaluating these research works with respect to the Free Radical Theory, the following conclusions were reached. 1. Of the 17 theses written in the Oriental medicine aspect, three theses used a single herb, nine theses used a complex prescription, four theses concentrated on the usage of the medicinal acupuncture, and one research paper focused on using scientific components. Common objection of these papers were on the verification of the efficacy of herbs. 2. Of the 18 these written in the Western medicine aspect, five theses used a single drug, seven theses conducted a research on the changes due to senescence, and 6 papers were on variety of topics. The main focus of these works were on the mechanism and pathology related to the senescence rather than on the suppression of senescence. 3. Among the theses written in the Oriental medicine perspective, a total of 48 herbs were utilized. 26 of these herbs has a tonification function on the Kidney. Six out of nine complex prescription mentioned above has a function of tonifying the Kidney. 4. With respect to the research subjects used on the experiments, 8 theses have used Senescence-Accelerated mice, 13 theses have used Sprague-Dawley mice, and remaining 7 papers have used human or other animals. 5. These are the categorization of the research items used: the weight (11) and weight changes of the visceral organs (9), the measurement of the content of peroxide-disease (9), the measurement of enzyme vitality (21), the blood and urine test (10), the experiment concerning immune system (3), the influence on the hepatic capability of metabolizing foreign substance (3), the effect on hepatic cell protection (3), the measurement of both the suppression of Free Radical and ability to create Free Radical (2), the measurement of effect of suppresing MDA(malondialdehyde) (4), the effect of eliminating DPPH Radical (2), and experiements about the functions (2). 6. The rate of vitalization of well known anti-oxidants such as Superoxide dismutase (SOD), Protein-bound SH, Nonprotein-bound SH, Glutathione(GSH), Catalase, and etc. were tested in 17 theses. Considering the conclusions mentioned above, the theses related to the senescence published in Korea elected different animals used for experiments, research items and the methods of research, the end result seems to be a lack of objectivity. Thus, I would argue that research methods to overcome such a deficiency need to be developed systematically.

Background: There is no assessment of internet sites that carry information on chronic pain disease. So we assessed the quality of information about postherpetic neuralgia available on Korean internet sites. Methods: The keywords 'postherpetic neuralgia', 'herpes zoster, neuropathic pain', 'herpes zoster, pain', 'herpes zoster' were searched in Korean on four search engines in Korea between the 1st to the 15th of May, 2009. We evaluated the outcome on two factors; the aspect of the contents which is subdivided into two categories, the content and authorship, and the technical aspect including web design, and efficiency. Results: A total of 26 internet sites were found. Among these sites, 6 (23%) informed by anesthesiologist. The average score of the 26 internet sites was only $37.4{\pm}20.1$ out of a total of 100. A mean score of the contents was $13.3{\pm}8.3$ out of 40 points, the authorship was $10.0{\pm}6.7$ out of 20 points, the design was $9.2{\pm}5.3$ out of 20 points, the efficiency was $6.8{\pm}4.3$ out of 20 points. When comparing the score between anesthesiologist and non-anesthesiologist, the contents was $18.7{\pm}7.4$ vs. $11.7{\pm}7.9$, the authorship was $13.4{\pm}4.7$ vs. $9.0{\pm}6.8$, the design was $12.5{\pm}4.2$ vs. $8.3{\pm}5.2$ and the efficiency was $6.8{\pm}4.5$ vs. $4.3{\pm}4.0$ (P < 0.05). Conclusions: There is a need for more accurate information about postherpetic neuralgia on the Korean internet by anesthesiologists.

Prevotella intermedia is one of the most frequently implicated pathogens in human periodontal disease and has a requirement for hemin for growth. This study has identified a hemin-binding P. intermedia protein by expression of a P. intermedia genomic library in Escherichia coli, a bacterium which does not require or transport exogenous hemin. The genomic library of P. intermedia was constructed into plasmid pUC18, transformed into Escherichia coli strain $DH5{\alpha}$, and screened for recombinant clones using heminbinding activity by plating onto hemin-containing agar. Approximately 5,000 recombinant E. coli colonies were screened onto LB-amp-hemin agar, single clone(pHem1) was exhibited a clearly pigmented phonotype. The 2.5kb insert DNA of pHem1 was determined by restriction enzyme mapping. Southern blot analysis of BamHI, BglII, EcoRI, HindIII and PstI-digested P. intermedia DNA indicated that single copy of the gene was present in the genome. Northern blot analysis revealed that the size of transcript was approximately 1.8 kb. The cloned gene contained a single ORF, consisting of approximately 850-residue amino acids. A BLAST search of the Institute for Genomic Research genes with similar nucleotide sequence revealed no significant similarity It needs further investigation to clarify the mechanisms of heme uptake in P. intermedia.

Objectives This study was aimed to review a standardized method of retention enema by extracting elements associated with methods of retention enema from papers involved. Methods 1) Data sources : Retrieval was made, using 'Enema' or 'Retention Enema' as search words in MEDLINE, The Cochrane Library, KISS, RISS, and NDSL DB. 2) Study selection : Two authors excluded irrelevant papers and chose qualified abstracts in the rest of the papers. The chosen studies were reviewed fully by the authors so that they could screen the significant papers based on the exclusion criteria. 3) Data extraction : Data on the total number of subjects, the target disease, the type, quality, length, diameter of catheter, the insertion length of catheter, the sample, the sample volume, the process of retention enema and the number of performing retention enema were extracted from the selected studies. Results & Conclusions The retention enema can be applied to gastrointestinal diseases, genitourinary diseases, metabolic diseases such as hypertension and diabetes, headaches and neurological disorders. The standardized treatment method is as following: 1) inserting a rental tube of 18-28 Fr that measures 20 to 30 cm into the patient's anus, 2) injecting herbal medicines which have purgative action or benefit on stomach and intestinal tract at the rate of 4 ml/min, and 3) holding them for 10 to 15 minutes.

The purpose of this study was to develop a home health care model in the public health system and to test the effectiveness of the model. Seven com-munity health practitioners in Yon- Cheon county. Kyunggi province, carried out home health care service for this research. The subjects of the home health care were a total of 111 community residents with chronic health problems and risk-prone infants and children; 29 persons with hypertension, 18 persons with diabetes, 12 persons with neurologic problems, 12 elderly, and 40 infants and children. During the period of study, from December, 1993 to March, 1995, a demonstrative home health care model was developed in the Yon-Cheon County community health centers with the cooperation of the Yon-Cheon Medical Center and Yon-Cheon Public Health Center for the first six months. A home care practice manual and recording system for home visits were also co-developed by the researchers and community health practitioners. Four workshops and monthly conferences were held for this purpose. Actual home care practice took place for two months, and on-going evaluation and replanning accompanied this process. The result of the evaluation of home care service were as follows. 1) For persons with hypertension, diabetes, neurologic problems, there was significant improvement in knowledge of disease and care, but no significant difference was seen in health behavior or symptoms after home care service. 2) No significant difference was seen in level of self esteem or depression after reminiscence therapy among 12 elderly subjects. 3) There were significant differences in satis-faction toward child rearing and parental sup-port, but no significant difference In education needs for parental role after home care service among parents of infants and children. 4) There was significant improvement in the quality of life among the subjects after the home care service. 5) Subjects responded that they were highly satisfied with the home care service given by the community health practitioners. Although, the actual implementation period was very short, and not all of the evaluation outcomes showed significant improvement, the home health care model of community health practitioners was, in general, positively evaluated. Through this re-search, the possibility of community health practitioners working as active home care personnel in the public health care system is supported. Further research with an expanded area and subjects for a longer period is recommended. Cost effectiveness research is also needed.

This study was undertaken to search for a new antiarrhythmic agent in natural plants. Extracts of Buxus microphylla var. koreana Nakai have been used as folk remedies of several diseases, including malaria and venereal disease, but any study on the pharmacological actions of this plant has not yet been carried out and its active ingredients have not been identified. In our laboratory, we isolated buxuletin (nonalkaloid) and cyclobuxine D (steroidal alkaloid) from Buxus microphylla var. koreana Nakai and reported their pharmacological actions: diuretic effects of buxuletin in rabbits and hypotensive effect of cyclobuxine D in rats. In the present study, we investigated the effect of cyclobuxine D on isolated frog heart and heart rate in urethane anesthetized rats. In order to clarify the mechanism of bradycardic effect of cyclobuxine D, we examined the changes of the ECG parameters (PR, QRS and R ${\alpha}$ T interval) produced by intravenous injection of cyclobuxine D in anesthetized rats. Cyclobuxine D depressed the contractile force in isolated frog heart and exerted a dose-dependent bradycardic effect in anesthetized rats. Intracerebroventricular injection of cyclobuxine D caused a fall in blood pressure and an increase in heart rate, but those effects were not significant. Cyclobuxine D prolonged the PR interval and RaT interval (${\alpha}$ Tindicates the apex of T), but was without significant effects on the duration of the QRS complex and PRc in urethane anesthetized rats.

'Medicinal water' have been used for the treatment of disease and the promotion of health. To study the quality and health effect of 'medicinal water', the eleven springs located near Taegu City during the period of March 27-February 17, 1986 were tested for biological and physiochemical examination and were checked for sanitary environment around the spring. Among them three springs (27.3%) had a good sanitary equipments and only one was negative for biological examination. Three 'medicinal warer' were accepted as potable by physicochemical examination. According to above findings, all of the 'medicinal water' sampled from the springs located near Taegu City were not potable by this sanitary survey adopted Drinking Water Standard in Korea. Kachang and Youngchum 'medicinal water' were more contaminated by heavy metals and bacteria than those of other springs. To solve the problem of contamination by heavy metals that originated from uncertain sources, we should search for the sources of water contamination, remove it completely and also support the environmental equipments and management system in protection of safe 'medicinal water' supply.
