  • Using the nodY::lacZ fusion system in Bradyrhizobium japonicum USDA 110, 22 flavonoids, which have structurally different features, were tested to define the role of the substituted functional groups as an inducer or inhibitor for the nod gene expression. A functional ,group of 4'-OH on the B-ring and the double bond between 2-C and 3-C on the C ring were required to induce the nod gene expression in B. japonicum USDA 110. In the case of isoflavones, the 4'-methoxyl group, which blocks the open 4'-OH functional group, did not significantly lower inducing activity, as compared with isoflavones with 4'-OH. However, all flavonols tested, which have a 3-OH functional group on the C-ring, did not induce, but inhibited the nod gene expression. Flavone, 7-hydroxyflavone, and kaempferol (5,7,4'-trihydroxyflavonol) at $1\;{\mu}M$ concentration significantly inhibited the nod gene expression induced by 7,4'-dihydroxyflavone. However, 7-hydroxy-4'-methoxyflavone at $1\;{\mu}M$ concentration showed a synergistic effect with genistein and 7,4'-dihydroxyflavone on the induction activity.

  • Galectin-3 is a ${\beta}$-galactoside-binding lectin that plays a role in neuroinflammation through cell migration, proliferation, and apoptosis. In the present study, regulation of galectin-3 was examined in the brain of mice infected with the Daniel strain of Theiler's murine encephalomyelitis virus (TMEV) at days 7 and 81 post-infection by immunohistochemistry. Immunohistochemistry revealed that galectin-3 was mainly localized in ionized calcium-binding adapter 1-positive macrophages/activated microglia, but not in Iba-1-positive ramified microglia. Galectin-3 was also weakly detected in some astrocytes in the same encephalitic lesions, but not in neurons and oligodendrocytes. Collectively, the present findings suggest that galectin-3, mainly produced by activated microglia/macrophages, may be involved in the pathogenesis of virus induced acute inflammation in the early stage as well as the chronic demyelinating lesions in Daniel strain of TMEV induced demyelination model.

  • The objective of this study was to investigate the effects of supplementation of an antiobese functional formula (FC-GT) on body weight and lipid metabolism in rats fed a high-fat diet. Three groups of male Sprague-Dawley rats were fed different diets for 6 weeks: normal control (NC), high-fat (HF), and high-fat supplemented with powdered antiobese functional formula (FC-GT) (5% wt/wt) groups. Although body weight was not significantly different among the groups, relative weights of epididymal and perirenal white adipose tissues were significantly lower in the FC-GT group than in the HF group. FC-GT supplementation significantly lowered the plasma total cholesterol and triglyceride concentrations, whereas it elevated the ratio of HDL-C/total-C and improved the atherogenic index. Hepatic cholesterol and triglyceride concentrations were significantly lowered in the FC-GT group compared to the HF group. The accumulation of hepatic lipid droplets and the epididymal white adipocyte size of the FC-GT group were diminished compared to the HF group. Hepatic HMG-CoA reductase activity was significantly lower in the FC-GT group than in the HF group. Plasma GPT activity was significantly lowered in the FC-GT group compared to the HF group. Additionally, fecal weight was significantly increased in the FC-GT group than in the HF group. In addition, contents of fecal triglyceride and cholesterol were significantly higher in the FC-GT group compared to the other groups. The antioxidant activities of hepatic SOD, CAT, and GR were significantly increased in the FC-GT group compared to the HF group. Hepatic mARS and plasma mARS levels were significantly lowered in the FC-GT group compared to the NC group. Accordingly, we conclude that supplementation of FC-GT improves plasma and hepatic lipid levels in high-fat fed rats.

  • Purpose: The purpose of this study was to identify effects of a self-management program on symptom and functional status, health perception, and quality of life(QOL) of patients with CHF. Methods: Patients with CHF as defined through clinical judgment using the Framingham criteria and EF<50% were enrolled in the study (experimental: 21, control: 20). The symptom focused self-management program consisted of coping behaviors for symptoms including dyspnea, chest discomfort/pain, dizziness, ankle edema, and basic self-management including medications, diets, activity, lifestyle changes. Experimental group received an educational booklet after survey, and periodic telephone follow-up by a trained nurse. Data were collected the 3rd day after admission and at 1 month, 3 months, and 6 months after discharge using questionnaires. Results: Significant differences were found in the presence of symptoms, health perception, and QOL between groups during follow-up. Although no significant difference was found in functional status, the experimental group reported better functional status than the control group. Conclusion: By facilitating self-management of CHF using tailored interventions including education programs and telephone monitoring, it is expected that patients will be able to monitor their symptoms routinely, adhere to therapeutic regimen, and have a better QOL.

  • The present study purposed to examine the effects of transcutaneous electrical nerve stimulation, self-stretching and functional massage on the recovery of muscle contraction force for muscle fatigue caused by sustained isotonic contraction. The subjects of this study were 45 healthy students. They were divided into transcutaneous electrical nerve stimulation group(n=15), self-stretching group(n=15) and functional massage group(n=15), and using Primus RS. We observed the pattern of changes in maximal voluntary isometric contraction force(MVIC) after causing muscle fatigue in quadriceps femoris muscle through sustained isotonic contraction. Maximal voluntary isometric contraction force(MVIC) were greatly increased after transcutaneous electrical nerve stimulation, self-stretching and functional massage. In the comparison of recovery rate of muscle contraction force for muscle fatigue caused by sustained isotonic contraction among the treatment groups, it did not show any significant differences. However, it showed that each treatment may be effective in recovery of muscle fatigue caused by sustained isotonic contraction.

  • Objectives : Functional dyspepsia is a type of disease characterized by bothersome postprandial fullness, early satiation, epigastric pain and burning without structural gastrointestinal disease. The aim of this study was to analyze the characteristics of functional dyspepsia patients and evaluate changes in symptoms, quality of life, and electrogastrography parameters before and after oriental medical interventions. Methods : We recruited forty-six functional dyspepsia patients who visited gastroenterology clinic in the oriental medicine hospital of Kyung Hee University between November 2009 and February 2011. Patients were assessed for their frequency of dyspepsia (based on short form-Leeds Dyspepsia Questionnaire: SF-LDQ), quality of life (based on functional dyspepsia-related quality of life questionnaire: FD-QoL), gastric motility (based on electrogastrography: EGG) on the first visit. Then, the effect of oriental medical interventions was evaluated using EGG on the second visit. Results : The majority of patients had symptoms of nausea and indigestion. The largest decrease in EGG parameters was found in the indigestion group. The frequency of regurgitation and postprandial EGG power % bradygastria showed a significant correlation. Also, significant correlations were found between some items of FD-QoL and some EGG parameters. Compared to the EGG parameters before oriental medical interventions, some parameters after treatment had positive results, implying the improvement of gastric motility disorder. We also found improvement of EGG parameters in both digestant medicinal group and digestant combined with qi-tonifying medicinal group. Conclusions : The results of this study suggest that clinical application of EGG can be an objective diagnostic tool in functional dyspepsia patients visiting oriental medical hospital.
