  • 고장초는 오랫동안 식용 및 의약 목적으로 차를 만드는 데 사용되어 왔다. 그러나 고장초를 고부가가치 식용 재료로 사용하는 연구는 불충분하다. 이전 연구에서 우리는 tricin이 고장초의 주요 화합물임을 확인했다. 본 연구에서는 고장초 추출물의 HepG2 세포 보호 효과를 조사하였다. 고장초 추출물 또는 tricin의 HepG2 세포에 대한 독성 실험 결과, 사용한 모든 농도에서 고장초 추출물 또는 tricin에 대한 독성은 나타나지 않았다. 또한 tert-butyl hydroperoxide (t-BHP)에 의해 감소된 세포 생존율은 고장초 추출물(100 ㎍/ml에서 69.23%) 또는 tricin (100 ng/ml에서 74.47%)에 의해 증가되었다. 또한 고장초 추출물(250 ㎍/ml) 또는 tricin (250 ng/ml)은 산화적 손상에 의한 활성 산소종(ROS) 생성을 효과적으로 억제했다. 또한 항산화 효소로 알려진 superoxide dismutase 1(SOD1), catalase, heme oxygenase-1 (HO-1), nuclear factor erythroid-related factor 2 (Nrf2)의 단백질 발현은 고장초 추출물(100 ㎍/ml에서 2.1, 1.6, 1.7, 1.5배) 또는 tricin (250 ng/ml에서 2.6, 1.8, 2.2, 2.0배) 처리로 증가했으며, 이는 고장초 추출물의 HepG2 세포 보호 효과는 tricin의 활성과 관련이 있다는 것을 시사한다. 종합하면 고장초는 간 기능개선 관련 기능성 식품 소재로 개발이 가능할 것으로 기대된다.

  • Objectives We evaluated the wound healing effects of Dangguijakyak-san (DJ) using C57BL/6 mice that were generated open wound. Methods The study was conducted with seven C57BL/6 mice assigned to each group, divided into the normal group, control group, vitamin E group, DJ low-dose group, DJ high-dose group. We measured total polyphenol, flavonoid contents, the size of the wound, liver function, pro-inflammatory cytokine activity in serum, inflammation-related proteins, adhesion molecules and chemokine proteins, collagen-related proteins in skin tissue and histopathological changes by H&E and Masson's staining. Results DJ treatment significantly reduced the area of the wound compared to the control group. Also, inflammatory cytokines were reduced and the expression of anti-inflammatory-related factors (interleukin-4 [IL-4] and IL-10) was significantly increased in the DJ treatment group. We identified that DJ treatment inhibits both pathways of inflammation, the mitogen-activated protein kinases and nuclear factor-κB pathway. Moreover, the protein expressions of Sirt1 (sirtuin 1), MCP-1 (monocyte chemoattractant protein 1), ICAM-1 (intercellular adhesion molecule 1), and VCAM-1 (vascular cell adhesion molecule 1) were decreased by DJ administration. Also, the expression of α-smooth muscle actin and collagen type I alpha 1, collagen-related proteins, that help skin recovery was significantly increased in the DJ treatment group. Histopathologically, a relatively thin epithelial layer could be observed in the DJ administration group, as well as an increase in fibroblasts and collagen fibers. Conclusions These data suggest that DJ treatment is effective in wound healing, suppressing inflammatory proteins, increasing skin repair factors and improving histopathological changes caused by wounds.

  • The study was conceived in relation to a concern over the growing gap between the needs of chronic patients and the availability of care from the current health care system in Korea. Patients with agonizing chronic pain, discomfort, despair and disability are left with helplessly unprepared families with little help from the acute care oriented health care system after discharge from hospital. There is a great need for the development of an alternative means of quality care that is economically feasible and culturally adaptible to our society. Thus, the study was designed to demonstrate the effectiveness of home heath care as an alternative to bridge the existing gap between the patients' needs and the current practice of health care. The study specifically purports to test the effects of home care on health expenditure, readmission, job retention, compliance to health care regime, general conditions, complications, and self-care knowledge and practices. The study was guided by the operations research method advocated by the Primary Health Care Operations Research Institute(PRICOR) which constitutes 3 stages of research : namely, problem analysis solution development, and solution validation. The first step in the operations research was field preparation to develop the necessary consensus and cooperation. This was done through the formation of a consulting body at the hospital and a steering committee among the researchers. For the stage of problem analysis, the Annual Report of Seoul National University Hospital and the patients records for last 5 years were reviewed and selective patient interviews were conducted to find out the magnitude of chronic health problems and areas of unmect health care needs to finally decide on the kinds of health problems to study. On the basis of problem analysis, the solution development stage was devoted to home care program development asa solution alternative. Assessment tools, teaching guidelines and care protocols were developed and tested for their validity. The final stage was the stage of experimentation and evaluation. Patients with liver diseases, hemiplegic and diabetic conditions were selected as study samples. Discharge evaluation, follow up home care, measurement and evaluation were carried out according to the protocols of care and measurement plan for each patient for the period of 6 months after discharge. The study was carried out for the period from Jan. 1987 to Dec. 1989. The following are the results of the study presented according to the hypotheses set forth for the study ; 1. Total expenditures for the period of study were not reduced for the experimental group, however, since the cost per hospital visit is about 4 times as great as the cost per home visit, the effect of cost saving by home care will become a reality as home care replaces part of the hospital visits. 2. The effect on the rate of readmission and job retention was found to be statistically nonsignificant though the number of readmission was less among the experimental group receiving home care. 3. The effect on compliance to the health care regime was found to be statistically significant at the 5% level for hepatopathic and diabetic patients. 4. Education on diet, rest and excise, and medication through home care had an effect on improved liver function test scores, prevention of complications and self - care knowledge in hepatopathic patients at a statistically significant level. 5. In hemiplegic patient, home care had an effect on increased grasping power at a significant level. However. there was no significant difference between the experimental and control groups in the level of compliane, prevention of complications or in self-care practices. 6. In diabetic patients, there was no difference between the experimental and control groups in scores of laboratory tests, appearance of complications, and self-care knowledge or self -care practices. The above findings indicate that a home care program instituted for such short term as 6 months period could not totally demonstrate its effectiveness at a statistically significant level by quantitative analysis however, what was shown in part in this analysis, and in the continuous consultation sought by those who had been in the experimental group, is that home health care has a great potential in retarding or preventing pathological progress, facilitating rehabilitative and productive life, and improving quality of life by adding comfort, confidence and strength to patients and their families. For the further studies of this kind with chronic patients it is recommended that a sample of newly diagnosed patients be followed up for a longer period of time with more frequent observations to demonstrate a more dear- cut picture of the effectiveness of home care.

  • 1. Objectives: Though the eating habits have improved and the living method has become convenient according to the economic growth thanks to the modern industrialization, because of the lack of exercise, obesity, wrong eating habits and stress etc, various symptoms of disease of adults are on the rise. This is the phenomenon that happens as the eating life has become life in the West along with the inundation of the western culture in our society. In this perspective, there has been many various clinical research that's been proceeded so far about the physical constitution and obesity, but there has been little research on the objective analysis of the clinical research about the alimentotherapy using taeeumjoweetang. 2. Methods: In this research we have checked the weights, fat rates, fat weight, abdominal fat rate, blood pressure, and BMI over the objects of the women that were diagnosed as lunisolar system as their physical constitution, and assessed the paramecium lipid, in-blood antioxidation enzyme and the damage of oxidization in the urine by physical constitution-specific of the body shapes that were determined by BMI. The statistical analysis of the current research was processed by using of SPSS 17.0 program. We have figure out statistical amounts such as the arithmetic average, average deviation rate and percentage number. Fro the verification of he significancy of each elements, we have used the paired t-test, ANOVA, Chi-square test at the level of p<0.05. 3. Results and Conclusions: Their characteristics are age $21.20{\pm}1.35$, height $160.30{\pm}6.11cm$, weight $64.66{\pm}8.72kg$, fat rates are $35.97{\pm}4.87%$, fat amount $23.40{\pm}5.48$, abdominal fat rate $0.823{\pm}0.03$, BMI $25.12{\pm}2.79kg/m^2$, and systolic blood pressure $111.60{\pm}10.28mmHg$ and diastolic blood pressure $68.60{\pm}7.43mmHg$ and we have let them take the medicine twice a day for 8 weeks. The clinical result for the Cholesterol, Triglyceride, HDL-cholesterol, LDL-cholesterol, SGOT, SGPT, of the object people was that for the function of the liver, the result of the SGOT and SGPT test was $17.16{\pm}3.05$, $15.00{\pm}2.99IU/L$, which was a decrease, and had statistical meaning, but for the SGOT, though the figure reduced to $11.92{\pm}4.61$, $10.80{\pm}3.07$, it had no statistical meaning. For the whole cholesterol level, the figure reduced to $169.00{\pm}19.95$, $160.08{\pm}22.52$ mg/dL and had statistical significance(p<0.05). Neuter fat number, Triglyceride has slightly increased to $67.52{\pm}36.32$, $68.08{\pm}47.33$ mg/dL but did not have any statistical meaning. The antioxdant enzyme marker standard marker, SOD has increased to $2.52{\pm}0.73$, $2.86{\pm}0.60U/ml$, and had statistical significance(p<0.01). Catalase also increased by $0.63{\pm}0.18$, $1.07{\pm}0.25mmol/ml$ and had statistical meaning(p<0.01). GPx also increased to $204.76{\pm}32.64$ nmol/ml and had statistical meaning(p<0.01). But, for the Total antioxidant, though it has raised to $1.51{\pm}0.26$, $1.57{\pm}0.17nmol/{\mu}l$, it did not have any statistical meaning. MDA of oxidative stress marker has decreased to $1.70{\pm}0.68{\mu}g/ml$, $1.21{\pm}0.50{\mu}g/m$ and had statistical significance(p<0.01). 8-OHdG also decreased $3.35{\pm}0.95ng/ml$, $2.21{\pm}0.50ng/ml$ and had statistical meaning(p<0.01). In this research, we have analyzed the various markers relating to BFM and changes in oxidative enzyme in blood by takingtaeeumjoweetang. Taeeumjoweetang has the positive effect on inbody antioxidant system and reducing the content of cholesterol, which is proven to help losing weight and improving hyperlipidemia statistically. With this research, we hope to improve the lifestyle of those who are either obese or need to manage their dietary habits, and also to become the touchstone of integrating Oriental Medicine with the science of food & nutrition.

  • 목적 : 수술이 불가능한 복강내 악성 종양으로 간외 폐쇄성 황달이 있는 환자에서 시행한 고식적 방사선치료의 효과를 알아보고, 그에 따른 인자들에 대하여 분석해 보고자 본 연구를 시행하였다. 방법 : 1984년 4월부터 1996년 12월까지 근치적 절제술이 불가능한 복강내 악성 종양으로 인한 간외 폐쇄성 황달로 본원에서 방사선치료를 받았던 72명의 환자들 중 방사선조사랑이 10 Gy 미만이었던 13명을 제외한 59명의 환자들에 대하여 후향적 분석을 시행하였다. 대상이 된 환자들은 위암이 21명($35.6\%$), 췌장암이 12명($20.3\%$), 간외 담도암이 15명($18.6\%$), 기타 종양이 11명($18.6\%$)이었다. 조직학적으로 확진된 경우는 31명($52.5\%$)이었으며, 이들 중 27명 ($87.1\%$)이 선암이었다. 외관상 황달을 주소로 내원한 경우는 47명($79.7\%$), 간기능 검사상 황달이 발견된 경우는 12명($20.3\%$)이었다. 복통은 29명($49.2\%$)의 환자에서 동반되었다. 경피적 담도배액술을 시행했던 경우는 24명($40.6\%$)이었으며, 항암화학요법이 병행된 경우는 32명($54\%$)이었다. 방사선치료는 증상완화를 목적으로 6 혹은 10 MV의 선형가속기를 이용하였고, 총 방사선조사량은 $10.8\~55.8$ Gy(중앙값 37.8 Gy)였다. 결과 : 전체 환자의 중앙 생존 기간은 $7.80{\pm}1.15$ 개월이었다. 고식적 방사선치료의 반응률에 대해서는 황달의 경우, 경피적 담도배액술을 시행한 환자와 시행하지 않은 환자를 비교해 보았을 때 반응률은 각각 $81.8\%$$66.7\%$로 나타났으나 통계적으로 유의한 차이를 보이지는 않았다. 또한 치료 후 $~2$주사이의 혈중 총빌리루빈의 감소 비율이나 혈중 총빌리루빈치가 $50\%$까지 감소하는데 걸리는 기간, 그리고 총빌리루빈치가 정상화되는 데까지 걸리는 기간등 황달이 회복되는 정도에 따라서도 통계적으로 유의한 차이를 보이지 않았다. 통증의 경우에는 항암화학요법을 시행한 경우가 방사선 단독치료에 비하여 통증의 완화정도가 높은 것으로 나타났으며 이 결과는 통계적으로 유의했다(p<0.05). 그러나 경피적 담도배액술을 시행했던 경우에는 오히려 통증의 반응률이 떨어지는 것으로 나타났다(p<0.05). 환자의 나이, 성별, 질환, 조직학적인 차이에 따른 방사선치료 결과의 차이는 나타나지 않았다. 생존율 분석에서는 Karnofski Performance Status (KPS)에 따른 환자의 임상 수행 능력이 높았던 경우(KPS>70)와 총방사선 조사량이 35 Gy이상이었던 경우에 생존율이 향상되는 결과를 보였으며(p<0.05), 또한 증상의 완화가 이루어진 경우에 생존율이 증가되는 결과가 나타났다(p<0.05). 치료와 관련된 합병증으로는 경피적 담도배액술을 시행한 경우 세균성 담관염이 12명($50\%$)에서 나타났으며, 항암화학요법을 시행한 경우에 치료와 관련된 합병증이 증가되는 것으로 나타났는데 이 결과들은 모두 통계적으로 유의한 차이를 보였다(p<0.05). 결론 : 본 연구에서는 외부 방사선치료를 시행함으로써 복강내 악성종양으로 인한 폐쇄성 황달로 인한 증상들을 완화시킬 수 있었으며, 대상이 된 환자들 모두가 수술이 불가능한 경우였음에도 불구하고 임상 수행 능력이 높았던 경우, 35 Gy이상의 방사선치료를 시행한 경우, 그리고 치료 후 증상의 완화가 있었던 경우에 생존율이 증가되는 것으로 나타났다. 향후 환자의 특성에 따라 이러한 고식적 치료들과 여러 가지 방사선치료의 기법들을 적절하게 운용함으로써 증상의 완화는 물론 생존율의 향상에도 기여할 수 있을 것으로 기대되지만, 이에 대해서는 좀 더 체계적인 연구가 필요할 것으로 생각된다.
