The heartwood of Rhus verniciflua has been known to be effective for lingering intoxication and diabetes mellitus and rheumatoidal arthritis in traditional folk medicine in Korea. We have previously reported that antimutagenic effect of flavonoids derived from the heartwood extract of R. verniciflua, and sulfuretin was the active component. Recently, we have demonstrated that sulfuretin could be an anti-inflammatory principle of the R. verniciflua heartwood partially dependent on cyclooxigenase-inhibitory activity. The present study was undertaken to demonstrate the anti-rheumatoidal arthritis effect of the R. verniciflua heartwood extract, its EtOAc fraction and the main flavonoids, sulfuretin and fustin. All the test samples showed variably significant inhibitory effects on hind paw edema induced by Freund's complete adjuvant reagent (FCA reagent). Sulfuretin treatment with 10 mg/kg (i.p.) for seven days showed the inhibitory effect of 54.2${\pm}$3.0%, Similar trends in RA- and CRP tests, vascular permeability test and trypsin inhibitor test were also found. In addition, no dead mouse was found even when the dose was increased up to 5,000 mg/kg (i.p.). Treatment with 250-1,500 mg/kg on normal rats did not show any marked toxicological significances in the tests of body weight gain, wet weight of organs and hepatic functions. These results suggested that the heartwood of R. verniciflua could be an adequate crude drug for rheumatoidal arthritis with an active component of sulfuretin. The toxicological safety of the heartwood of R, verniciflua is contrasted to known severe allergenic action of the stem bark or its exudate.
Background: There is a need for index research on music therapy activities for the elderly in Korea. Purposes: This study aims to suggest application standards in music therapy by surveying the elderly's preference for music therapy activities. Methods: A survey of music-related actions and musical instrument preferences was conducted with 91 older people in 4 nursing homes. The questionnaire consisted of information about music activities, genres of songs, types of instruments, methods of movement, and purpose of participation in activities. Results: The preference for musical activities was for playing musical instruments, followed by singing, music appreciation, flowing movements, and concert-oriented activities. Music genres appeared in the order of popular songs, folk songs, and children's songs. The instrument type preferred drums, followed by shakers and woodblocks. As a movement application method, movement using themes is preferred. Participating in music activities was leisure, followed by stress relief and emotional cultivation. Conclusion: When applying music therapy to the elderly, it predicted that the treatment effect would be high when the elderly focus on playing musical instruments and singing activities preferred by the elderly. Music genres selected from popular music and folk songs, and musical instruments are drums and shakers. Therefore, if you use it, you can expect a more significant effect.

Objectives : this study was to access the effect of Hyeonggaeyeongyotang water extracts, a polyherbal formula has been used as folk medicine, on the fertility and early embryonic development of male and female Wistar rats when administered by oral gavage. Methods : In male rats, Hyeonggaeyeongyotang extract were dosed 4 weeks before pairing and 2 weeks after mating including the mating periods up to termination after necropsy of the majority of the females. In female rats, they were dosed 2 weeks before pairing, and from Day 0 to Day 7 of gestation. This study was conducted in accordance with the recommendations of the KFDA Guideline [2005-60] for Detection of Toxicity to Reproduction for Medicinal Products. Results: 1. No Hyeonggaeyeongyotang extract treatment-related changes on the clinical signs and mortalities, the Food consumptions, the Body weights and gains were demonstrated in all dosed levels tested in this study except for 500ml/kg-dosing male group in which a significant(p<0.05) increase of body gains was detected during day 0-7 after dosing. 2. No Hyeonggaeyeongyotang extract treatment-related changes on the pre-coital intervals, the estrus cycles, the mating index, conception rate and fertility index were demonstrated in all dosed levels tested in this study. 3. No Hyeonggaeyeongyotang extract treatment-related gross findings on reproductive organs, the weights of reproductive organs, histopathological findings on reproductive organs, the corpora lutea number, implantation site number, live fetus number, number of resorpted embryo and pre-and post-implatation loss were demonstrated in all dosed levels tested in this study. Conclusions : Base on the results, it is considered that the NOAEL (No-Observed-Adverse-Effect Level) for fertility and early embryonic development toxicity of Hyeonggaeyeongyotang extract was under 2000ml/kg/day in Wistar male and female rats because there no treatment-related changes on the fertility and early embryonic developmental index were demonstrated in all dosed levels tested.

This study was to identify the nursing intervention method in finding out the incidence, risk factor, prevention and treatment of bed sore cilents who received regional home care nursing services. The eleven home care nurse practitioners took the survey on 97 patients who received home care nursing service from Seoul City Nurses Association for one month from September 26 to October 26 1996. A modified version of Braden's bed sore assessment tool for bed sore risks and a tool for assessment of bed sore stage and measurement bed sore sizes by Bergstrom, Braden, Laguzza and Holman(1987) were as research tools for this study and a questionnare with 40 questions and 12 items on nursing activities was used to find out the prevention and treatment of bed sores. Also, two open ended questions were used on current approaches and efforts of the treatment being applied to clients. The finding of the study were summarized as following : 1. The rate of bed sore occurrence was 47.4% 2. The areas of bed sore occurrence were hip(28.9%), sacrum(18.6%), great trochanter(14.4%) and the average number of sore spots were 2.26 3. Two groups-one with bed sores and the other without-were studied to determine prediction factors for bed sore risks. Sensory function, humidity, level of activity, mobility, nutrition, skin friction and chapping and body temperature turned out to be statistically significant factors for bed sores. Also the age of clients turned out to be a individual characteristic variable significantly affecting the rate of bed sore occurrences. 4. The education for clients and family on systematic skin assessment and bed sores and practice of active/passive R.O.M. are mainly used as nursing activities for bed sore care. 5. The treatment method varied by stages of bed sores. Sometimes folk remedies like applying the powders of dried elm tree roots to sores were used. Good nutrition, frequent position change and skin care turned to be the most effective means to fast recovery of sores.
The brine treatment applied during the fabrication of forged high tin bronze objects is considered effective at the removal of surface oxide layers developed at elevated temperatures. There is not much information, however, available for the understanding of its exact effect and purpose. This work performed laboratory experiments to characterize the effect brine treatments produce on the surface of bronze objects during fabrication. Specimens were first made in the bronze shop of the Yongin folk village under varying conditions of brine treatments, and the results obtained were then used in the following laboratory experiments where the effect of brine treatments were investigated in terms of brine concentrations, alloy compositions and thermo-mechanical treatments. The results show that oxide layers generated at high temperature are easily removed by the brine treatment. It was found that the element, chlorine, played a key role in the removal of such oxide layers as opposed to the other constituent of the brine, sodium, makes no notable contribution. In bronze alloys containing 22% tin, this brine effect is obtained regardless of the application of forging as long as the brine concentration is over 0.5% based on weight. In alloys containing lead, however, no brine effect is observed due to the molten lead that emerges from inside the hot bronze specimen and forms a thin layer on its surface.
Yacon has been used in folk medicines as a medicinal tea for hypoglycemia treatment. In a recent study described herein, antioxidative, antibacterial, antifungal activities, and cell-protective functions of yacon leaves have been reported. To evaluate the effects on fibrosis on pancreatitis, the efficacy of 1% of yacon extract (YE) on dibutyltin dichloride (DBTC) (8 mg/kg)-induced pancreatitis in rats was examined. On the 21st day after the DBTC treatment, a large increase in collagen was observed in the pancreas in the DBTC-treatment group (DT). But this was noticeably decreased with YE. In relation to the expression of COX-2, there was no response or a very weak response in the pancreas of the control group (CON). However, in DT, strong expression of COX-2 was observed in the pancreas on the 14th day, and COX-2 was present in inflammatory cells in the pancreas of the DT, especially on the 21st day. The expression was decreased for YE compared with DT. A remarkable increase in TGF-${\beta}1$ expression was observed in inflammatory cells in the pancreas in DT on the 21st day, whereas the expression was not found in YE after 21 days. However, on the 21th day, TGF-${\beta}1$ expression was increased in acinar cells of YE compared with DT. VEGF expression was very similar to the expression of in the pancreas. These results suggest that YE has an inhibitory effect on DBTC-induced pancreatic fibrosis.

Objectives: This study was conducted to investigate the treatment status and its related factors of the rural hypertensives. Methods: A questionnaire survey was performed to 618 rural hypertensives during September, 2002. Results: The proportion of those who were compliant to the antihypertensive medication was 68.9%. The compliance rate to the antihypertensive medication was significantly related with sex and economic status(p<0.05). That is, if they were female, higher economic level, the regular antihypertensive medication rate was higher. The regular antihypertensive medication rate was higher when they had higher knowledge for hypertension, higher severity for hypertension of him or her(p<0.01). And the compliance rate to the antihypertensive medication was significantly related with hypertensives' own explanatory model for hypertension(p<0.01). The rate of drug use except antihypertensives was 12.5%. The rate of drug use except antihypertensives was higher when they experienced side effects of antihypertensive drug and when they had irregular medication for antihypertensive drug(p<0.01). The rate of medical equipment use was 18.9%. The utilization rate of medical equipment such as jade mat, germanium material was significantly related with age, experience of side effects of antihypertensive drug, medication status for antihypertensive drug(p<0.05). The rate of folk therapy use was 16.2%. The rate of folk therapy use was higher when they had no family, when they had knowledge about hypertension on the average, when they had hypertension over 10 years(p<0.05), and when they experienced side effects of antihypertensive drug and when they had irregular medication for antihypertensive drug(p<0.01). The rates of drug use except antihypertensives, medical equipment use, and folk therapy were significantly related with hypertensives' own explanatory model for hypertension(p<0.05). Conclusions: On consideration of above findings, it would be essential to provide knowledge about hypertension and its treatment, and severity of hypertension complications through health education.
Zingiber officinale Roscoe has been widely used as a folk medicine to treat various diseases, including cancer. This study aims to re-examine the therapeutic potential of co-administration of natural products and cancer chemotherapeutics. Candidate material for this project, ${\alpha}$-zingiberene, was extracted from Zingiber officinale Roscoe, and ${\alpha}$-zingiberene makes up $35.02{\pm}0.30%$ of its total essential oil. ${\alpha}$-Zingiberene showed low $IC_{50}$ values, $60.6{\pm}3.6$, $46.2{\pm}0.6$, $172.0{\pm}6.6$, $80.3{\pm}6.6$ (${\mu}g/mL$) in HeLa, SiHa, MCF-7 and HL-60 cells each. These values are a little bit higher than $IC_{50}$ values of general essential oil in those cells. The treatment of ${\alpha}$-zingiberene produced nucleosomal DNA fragmentation in SiHa cells, and the percentage of sub-diploid cells increased in a concentration-dependent manner in SiHa cells, hallmark features of apoptosis. Mitochondrial cytochrome c activation and an in vitro caspase-3 activity assay demonstrated that the activation of caspases accompanies the apoptotic effect of ${\alpha}$-zingiberene, which mediates cell death. These results suggest that the apoptotic effect of ${\alpha}$-zingiberene on SiHa cells may converge caspase-3 activation through the release of mitochondrial cytochrome c into cytoplasm. It is considered that anti-proliferative effect of ${\alpha}$-zingiberene is a result of apoptotic effects, and ${\alpha}$-zingiberene is worth furthermore study to develop it as cancer chemotherapeutics.

The seed of Vigna angularis has long been cultivated as a food or a folk medicine in East Asia. Genistein (4',5,7-trihydroxyisoflavone), a dietary phytoestrogen present in this plant, has been known to possess various biological properties. In this study, we investigated the possible lifespan-extending effects of genistein using Caenorhabditis elegans model system. We found that the lifespan of nematode was significantly prolonged in the presence of genistein under normal culture condition. In addition, genistein elevated the survival rate of nematode against stressful environment including heat and oxidative conditions. Further studies demonstrated that genistein-mediated increased stress tolerance of nematode could be attributed to enhanced expressions of stress resistance proteins such as superoxide dismutase (SOD-3) and heat shock protein (HSP-16.2). Moreover, we failed to find genistein-induced significant change in aging-related factors including reproduction, food intake, and growth, indicating genistein exerts longevity activity independent of affecting these factors. Genistein treatment also led to an up-regulation of locomotory ability of aged nematode, suggesting genistein affects healthspan as well as lifespan of nematode. Our results represent that genistein has beneficial effects on the lifespan of C. elegans under both of normal and stress condition via elevating expressions of stress resistance proteins.
Euonymus alatus(Thunb.) Sieb has been used for cancer theraphy such as Liver cancer, esophagus cancer, stomach cancer, and uterine cancer in folk. Eupolyphaga simemsis(ES) extracted from Euonymus alatus(Thunb.) Sieb increases HDL-C/TC ratio and LCAT activity. TGF-${\beta}$ and Insulin has been Knoen as factors to induce the supression of proliferation of Hep3B, Human hepatoblastoma cell. Plasma HDL3-C involved in carbohydrate methabolism in the liver was maintained in low level by Euonymus alatus(Thunb.) Sieb. The low level of plasma HDL3-C suppresses the transition from normal liver to Fat liver. Finally, this resuly in suppression of cancer in liver. In this study, Euonymus alatus(Thunb.) Sieb showed higher cell toxicity in hepatoblastoma cell(Hep3B) compared to the uterine cancer cell(HeLa). This means Euonymus alatus(Thunb.) Sieb seems not to affect in the all kinds of cancer. In future, we will study whether Euonymus alatus(Thunb.) Sleb have an effect on the liver cancer induced by virus and hepatocellular carcinoma. Also, the mechanims of suppression of cell proliferation in HCC need to investigated.
