  • As a family respond to any stressful situation as a whole system, cancer diagnosis of a child, as a serious life event, could be emotional shock to destroy homeostasis of the family system. A family has a resilient capacity to adjust and adapt to stressful events. Previous studies have been focused on family stress and adaptation, but little attention has been given to family value as one of resilient factors. The data for model testing were collected from July 18, 2000 to August 30, 2000 and the analysis included 309 parents of children who are diagnosed as cancer, 18 or less years of age, and treated either hospitalized or at the outpatient clinics. The data analysis utilized SAS 6.12 and LISREL 8 for descriptive statistics, correlation, cluster analysis, factor analysis, and LISREL. The study findings are as follows. 1) Monthly income (γ=-0.28, t=-5.81) was the most important factor to explain family strain along with family support (γ=-0.11, t=-2.43), severity of children's illness (γ=0.26, t=5.22), and family stressor (γ=0.22, t=4.62). All of these factors together explained 40% of variance in family strain. 2) Among general family value, the relationship with the parents (γ=0.28, t=4.89) and relationship with the children (γ=0.20, t=3.60) showed positive effects to family value for cancer children, while relationship with the spouse (γ=-0.19, t=-3.22) and the age of the cancer children (γ=-0.11, t=-2.21) showed negative effects. These predictors together explained 22% of variance in family value for cancer children. 3) Family hardiness was explained mostly by family strain (γ=-0.53, t=-8.65) along with direct negative effects of family persistency and indirect negative effects of severity of children's illness, family stressor, relationship with the spouse, and the children's age. Family value for cancer children was the most important predictor with positive effect (γ=0.44, t=6.76) along with indirect effects of monthly income, relationship with the parents, relationship with the children, support from family and significant others, and confidence with the health professionals. 51% of variance in family hardiness was explained by all of these predictors. 4) The most important predictor for family adaptation was family stressor (γ=-0.50, t=-6.85) with direct and indirect negative effects along with the severity of children's illness (γ=-0.27, t=-5.21). However, family value for cancer children showed compromised total effect (γ=-0.13, t=-1.99) with negative direct effects (γ=-0.28, t=-3.43) and positive indirect effects (γ=0.14, t=3.01). Similarly, confidence with the health professionals also showed compromised total effect (γ=0.09, t=1.99) with positive direct effects and negative indirect effects. Family hardiness showed the biggest positive direct effects while other factors such as monthly income, family stressor, family persistence, support of family and significant others, relationship with the parents, relationship with the children, and relationship with the spouse, and children's age showed indirect effects only. 39% of variance in family adaptation was explained by all of these predictors.

  • The immune system acts to protect the host from infectious agents that exist in the environment and from other noxious insults. The immune system has two functional divisions: the innate and the acquired. Both components involve various factors such as cytokines. A number of methodologies exist to assess aspects of immune function. There are large inter-individual variations in many immune functions even among the healthy. Genetics, age, gender, smoking habits, habitual levels of exercise, alcohol consumption, diet, stage in the female menstrual cycle, stress, history of infections and vaccinations, and early life experiences are likely to be important contributors to the observed variation. While it is clear that individuals with immune responses significantly below 'normal' are more susceptible to infectious agents and exhibit increased infectious morbidity and mortality, it is not clear how the variation in immune function among healthy individuals relates to variation in susceptibility to infection. Oriental medicine is an important factor contributing to immune competence. The author investigated the immune enhancement effects of Bojungikkitanggami-bang (BITB). The forced swimming test (FST) has been used as a screening model for new immune enhancement agents. In the present study, the author investigated the effects of BITB on FST and blood biochemical parameters related to fatigue, glucose (Glc); blood urea nitrogen (BUN); lactate dehydrogenase (LDH); creatinine; and total protein (TP). The author found that BITB (1 g/kg) significantly reduced the immobility time in the FST compared to the control. In addition, the contents of Glc, LDH, BUN, TP in the blood serum were increased in BITB (1g/kg)-fed group. Also, the author investigated the effects of BITB on the production of cytokines in human T-cell line, MOLT-4 cells. BITB (1 mg/ml) significantly increased the interferon (IFN)-vproduction compared with media control (about 2.2-fold for IFN-γ) at 24 h. However, BITB has not affect the production of IL-2 and IL-4. In addition, BITB increased the protein expression level of IFN-γ in MOLT-4 cells. Thus, BITB may have therapeutic value in generating or enhancing immune function in a clinical setting.

  • 본 연구는 선행연구를 통한 으름 추출물의 간 보호 효과에 대하여 으름 추출물 내 유효물질로 알려진 oleanolic acid와 hederagenin을 생쥐에 투여하였을 때 알코올로 인한 급성 간독성 상태에서 간 보호 효과를 조사하였다. 그 결과 oleanolic acid와 hederagenin의 투여는 알코올로 유발된 급성 간독성 상태에서 혈중 알코올 농도 감소 및 alcohol dehydrogenase mRNA 발현을 증가시키는 것으로 나타났으며, 간 조직 내 항산화 물질인 glutathione(GSH)의 농도를 증가시키고, GSH synthetic enzyme의 mRNA 발현 역시 증가시키는 것으로 확인되었다. 또한 염증반응 지표인 tumor necrosis factor-alpha의 mRNA 발현도 억제하는 것으로 분석되었다. 위의 결과들과 기존의 실험에서 확인한 으름 추출물의 간 보호 효과를 종합하였을 때 으름 추출물의 알코올로 유발된 산화 스트레스, 염증반응에 대한 간 보호 효과는 추출물 내 유효물질로 알려진 oleanolic acid 및 hederagenin의 작용에 의한 것이라 생각한다.

  • KIF5는 2분자의 kinesin heavy chain (KHC)과 2분자의 kinesin light cham (KLC)으로 구성되며 미세소관과 직접 결합한다. KIF5는 여러가지 세포 내 소기관을 이동시키나 KIF5가 이동시키는 운반체가 어떻게 특이적으로 결합하는지는 아직 밝혀지지 못하였다. 본 연구에서 효모 two-hybrid system을 사용하여 KLC1의 tetratricopeptide repeats (TRP) 부위와 결합하는 세포 내의 단백질을 분리하였다. 결과 KLC1와 특이적으로 결합하는JNK/stress-activated protein kinase-associated protein 1 (JSAP1/JIP3)을 분리하였다. 이러한 결합은 KLC1의 TRP1, 2 영역과 JSAP1의 leucine zipper 영역이 결합에 관여하며, 또한 효모 two-hybrid assay에서 JSAP1은 KLC2와 결합하지만 신경세포에서 발현하는 KIF5A, KIF5C 그리고 모든 세포에서 발현하는 KIF5B와는 결합하지 않았다. 단백질간의 결합을 pull-down assay로 확인한 결과 KLC1은 glutathione S-transferase (GST)와는 결합하지 않으나 GST결한 JSAP1과는 결합하였다. 또한 생쥐의 뇌 파쇄 액으로부터 JSAP1 항체로 면역침강을 행한 결과 KLC1은 JSAP1과 같이 침강하였다. 이러한 결과들은 KLC1은 JSAP1과 결합하며, JSAP1은 KLC1의 수용체로세포 내 KIF5의 수송의 매개 단백질로 작용함을 시사한다.

  • This study was to examine single or combined in vitro effects of environmental endocrine disruptors on boar sperm characteristics, oxidative stress damage in sperm and development of porcine IVF embryos. Addition of various concentration of NP (10, 20, $30{\mu}M$), DBP (10, 50, $100{\mu}M$) and BPA (1, 5 or $10{\mu}g/ml$) on boar sperm characteristics such as percentages of sperm motility, viability, membrane integrity and mitochondrial activity were dose-dependently decreased within 3, 6 or 9 hr incubation period (p<0.05). The overall detrimental effects increased with incubation time increasement. NP, DBP and BPA showed the detrimental effects on sperm membrane and mitochondria of energy production organelles affecting cell viability with the dependancy of dose and incubation time. In combination effects, NP ($10{\mu}M$) + DBP ($10{\mu}M$) significantly decreased boar general sperm characteristics for 3 or 6 hr incubation period compared with control (p<0.05). When both of NP and DBP concentrations (NP; $30{\mu}M$, DBP; $100{\mu}M$) increase, the detrimental effects on sperm characteristics were larger than those of low concentration combination (p<0.05). The inhibitory effects of NP ($30{\mu}M$) + BPA ($10{\mu}g/ml$) on sperm characteristics were larger than those of NP ($10{\mu}M$) + BPA ($1{\mu}g/ml$) (p<0.05). DBP ($100{\mu}M$) + BPA ($10{\mu}g/ml$) decreased sperm characteristics compared with the low concentration combination (DBP $10{\mu}M$ + BPA $1{\mu}g/ml$, p<0.05). This result indicates the detrimental effects of both chemicals on sperm characteristics were dose dependent. Addition of NP ($30{\mu}M$) + DBP ($100{\mu}M$), NP ($30{\mu}M$) + BPA ($10{\mu}g/ml$), DBP ($10{\mu}M$) + BPA ($1{\mu}g/ml$) or DBP ($100{\mu}M$) + BPA ($10{\mu}g/ml$) significantly increased lipid peroxidation for 3 or 6 hr incubation period (p<0.05) compared with no addition control. NP (${\geq}20{\mu}M$) decreased the percentages of IVF embryo development from morulae and blastocyst stages (p<0.05) and its detrimental effects were dose-dependant. BPA 0, 1, 5 or $10{\mu}g/ml$ decreased significantly and dose-dependently the percentage of morulae plus and blastocysts (p<0.05). Combinations of DBP ($100{\mu}M$) plus NP ($30{\mu}M$) and DBP ($100{\mu}M$) plus BPA ($10{\mu}g/ml$) did not affect on morulae and blastocyst development, but NP ($30{\mu}M$) plus BPA ($10{\mu}g/ml$) has significant detrimental effect on embryo development at these stages (p<0.05). These overall results indicate that the partial detrimental effects on boar sperm characteristics and embryo development by NP, DBP, BPA or the combination of these chemicals might be due to the increasement of lipid peroxidation and free radical formation in the cell and there were no specific interaction effects on boar sperm and embryo degeneration among the combined treatments.

  • DNA/RNA결합 단백질로 다양한 기능을 한다고 알려진Fused in Sarcoma (FUS)의 유전자 돌연변이가 루게릭병 및 전측두엽성 치매 환자에서 발견되었다. 정상적인 FUS는 핵에 위치하지만 병리상황에서 FUS는 세포질로 잘못 타기팅 되어 스트레스 응집체와 결합된 단백질 응집체를 형성하는 것으로 알려졌다. 그러나 이들에 의한 스트레스 응집체 형성 기전 및 응집체 형성에 관여하는 FUS의 도메인은 정확히 알려지지 않았다. 따라서, 본 연구에서는 루게릭병 연관 FUS 미스센스 돌연변이(P525L, R521C, R521H, R521G)의 세포내 위치 및 세포질 FUS의 응집체 형성에 관여하는 FUS내 도메인을 분석하고 동정하고자 하였다. 이를 위해 먼저, FUS 미스센스 돌연변이의 세포내 위치를 분석한 결과, P525L대부분은 세포질로 위치하여 스트레스 응집체를 형성하는 반면, R521C, R521H, R521G는 핵과 세포질에 위치하였다. 이를 통해 FUS의 핵으로의 이동에는 FUS의 마지막 2개의 아미노산이 매우 중요함을 확인할 수 있었다. 세포질로 빠져 나온 FUS의 응집체 형성에 관여하는 FUS도메인 분석을 위해서 핵 위치서열이 결손되어 대부분 세포질 응집체를 형성하는 FUS-∆17를 이용하여, 다양한 도메인 결손 돌연변이를 제작하고, 이들의 응집체 형성여부를 분석하였다. 그 결과, SYGQ-RGG1나 RGG2-ZnF-RGG3없는 세포질 FUS (FUS-∆SYGQ-RGG1-∆17, FUS-∆RGG2-ZnF-RGG3-∆17)는 스트레스 응집체를 형성하지 않은 반면, RRM이 없는 FUS-∆RRM-∆17은 FUS-∆17에 비해 많은 스트레스 응집체를 형성함을 알 수 있었다. 따라서, 도메인 분석결과 세포질의 FUS는 SYGQ-RGG1나 RGG2-ZnF-RGG3 도메인을 통해 FUS 스트레스 응집체 형성이 촉진되고, RRM도메인은 FUS 응집체 형성을 저해하고 있는 것으로 생각된다. 이러한 연구 결과는 FUS의 스트레스 응집체 형성과 연관된 다양한 퇴행성 뇌질환의 발병기전에 대한 이해뿐만이 아니라 이들 질환 치료를 위한 치료 후보 타겟 물질 발굴에 중요한 단서를 제공할 수 있을 것이다.

  • Pharmacologic coronary vasodilation in conjunction with myocardial perfusion scintigraphy has become an alternative to dynamic exercise test for the diagnosis and risk stratification of coronary artery disease, especially in patients who are unable to perform adequate exercise. Dipyridamole and adenosine have been used for pharmacologic stress testing with myocardial perfusion imaging. Adenosine is a potent coronary vasodilator with rapid onset of action, short half-life, near maximal coronary vasodilation and less serious side effects. ST segment depression has been reported in about 7-15% of patients with coronary artery disease receiving dipyridamole in conjunction with myocardial perfusion imaging. The exact cause and clinical significance are not known. In order to evaluate the relationship between adenosine-induced ST segment depression during $^{99m}Tc$-MIBI myocardial perfusion scintigraphy and the severity of coronary artery disease, we performed $^{99m}Tc$-MIBI imaging after intravenous Infusion of adenosine In 120 patients with suspected coronary artery disease. Of the 120 patients, 28 also performed coronary angiography. There were 24 patients with ST segment depression during $^{99m}Tc$-MIBI scintigraphy and 96 patients without ST segment depression. Adenosine was infused Intravenously at a dose of 0.14mg/kg per minute lot 6minutes and $^{99m}Tc$-MIBI was injected at 3 minute. We then com-pared the hemodynamic changes, side effects, scintigraphic and angiographic findings. Heart rate increased $90{\pm}19$ beats/minute in the group with ST depression compared with $80{\pm}16$ beats/minute in the group without ST depression(p<0.05). Baseline systolic blood pressure was significantly higher in the group with ST depression($152{\pm}27$ mmHg) than in the group without 57 depression($140{\pm}21$mmHg, p<0.05). Double product at baseline($10.90{\pm}2.77$ versus $9.55{\pm}2.34\;beats/minute{\times}mmHg$) and during adenosine infusion($12.72{\pm}3.89$ versus $10.83{\pm}2.98\;beats/minute{\times}mmHg$) were significantly higher in the group with ST depression(p<0.05). The incidence of anginal chest pain was also significantly higher in the group with ST depression(ST versus 29%, p<0.0001). The $^{99m}Tc$-MIBI images were abnormal in 23(96%) patients with ST segment depression and 66(69%) patients without ST segment depression(p<0.05). In patients with ST segment depression, there were more reversible perfusion defects than in patients without ST segment depression(83 versus 55%, p<0.05). The number of abnormal segments were significantly higher in the group with ST depression($3.05{\pm}2.01$ versus $1.51{\pm}1.45$, p<0.005). In patients with ST segment depression, there were more segments of reversible perfusion defects than in patients without segment depression($2.15{\pm}2.11$ versus $0.89{\pm}1.24$, p<0.05). There were no differences in the angiographic severity by vessel(p ; NS). We concluded that ST segment depression during $^{99m}Tc$-MIBI myocardial perfusion scintigraphy with Intravenous adenosine is related to the severity of coronary artery disease.

  • 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.

  • 오미자와 산수유는 한국을 포함한 동아시아 지역에서 다양한 질병의 예방 및 치료에 오랫동안 사용되어 왔다. 최근에 이들 추출물에 의한 양성 전립선 비대증(BPH)의 발병 및 진행을 억제할 수 있다는 가능성에 대한 보고가 있었지만 관련 기전에 대한 연구는 여전히 부족한 실정이다. 본 연구에서는 LNCaP 전립선 세포를 사용하여 DHT 처리에 의한 in vitro BPH 모델에서 오미자 및 산수유 추출물에 의한 BPH의 개선 가능성을 조사하였다. 본 연구의 결과에 의하면, 오미자와 산수유의 열수 및 에탄올 추출물은 DHT 처리에 의해 LNCaP 세포의 증식을 유의적으로 억제하였으며, DHT로 유도된 BPH 바이오 마커와 성장인자의 발현을 현저히 감소시켰다. 그들은 또한 세포사멸 관련 인자의 발현을 조절하였고, DHT 매개 산화적 스트레스를 유의적으로 감소시켰으며, BPH 발병에 관여하는 주요 인자에 대한 보호 효과는 열수 추출물보다 에탄올 추출물 처리군에서 더 효과적이었다. 또한, BPH에 대한 보호 효과는 오미자와 산수유의 에탄올 추출물 단독 처리군보다 1:1 복합 혼합물 처리군에서 더 높았으며, 60% 에탄올 추출물이 40% 에탄올 추출물보다 더 높은 개선 효과를 보였다. 따라서 본 연구 결과는 오미자와 산수유 추출물이 항산화 활성과 연관된 androgen 신호 전달 경로의 억제를 통해 전립선 세포의 과다 증식을 방지함으로써 BPH 개선에 관여할 수 있음을 의미한다. 따라서 오미자와 산수유 추출물은 BPH의 임상 치료에 유용할 수 있으며, 이 두 추출물의 조합은 BPH 개선에 상승 효과를 낼 수 있을 것이다.
