Objectives This experimental study was designed to investigate the effect of Phaseolus angularis shell on metabolic syndrome. Methods Each 5 C57BL/6J mice were randomly assigned to normal diet group, high-fat diet(HFD) control group, high-fat diet plus 15.6 mg/kg/day of Orlistat(HFD-Orlistat) group, high-fat diet plus 100mg/kg/day of Phaseolus angularis shell extract(HFD-PAS_E) group. Weight, the blood chemical and hematologic parameter was med. The mRNA expression was assayed through Reverse transcriptase polymerase chain reaction(RT-PCR). Results In HFD-PAS_E group, the body weight gain, weight of liver, and the level of LDL-Cholesterol were significantly decreased and the level of HDL-Cholesterol were significantly increased. The size of adipocyte in HFD-PAS_E group was smaller than HFD group's. In HFD-PAS_E group, the expression of leptin, PPAR-${\gamma}$, AP2/FABP4 mRNA in liver adipocyte tissue was decreased, the expression of Adiponectin, UCP-2 mRNA in liver adipocyte tissue was increased and the expression of Leptin, C/EBP-a, AP2/FABP4 mRNA in epididymal adipocyte tissue was decreased. Conclusion These results suggest that Phaseolus angularis shell has inhibitory effects on metabolic syndrome by reducing the body weight and the levels of lipid contents in high-fat-diet induced obese mice.

Objectives The purpose of this study was to find out the effects of ChondroT on arthralgia of the Collagenase-induced osteoarthritis in rats. Methods Osteoarthritis was induced into rat by injecting Collagenase in its knee joint. Rats are divided into a total of 8 groups (n=6). Normal group was not induced for osteoarthritis whereas control groups were induced for osteoarthritis by Collagenase. Positive-A (Indomethacin) was injected with Collagenase and after 8 days, 2 mg/kg of Indomethacin was medicated. Positive-B (JOINS TAB) was injected with Collagenase and after 8 days, 20 mg/kg of JOINS TAB was medicated. Experimental groups (Chondro T) at three dose levels (50, 100 and 200 mg/kg) were injected with Collagenase and after 8days they were medicated with 10 ml/kg. Indomethacin, JOINS TAB and ChondroT were medicated each substances once a day for 10 days. Thereafter, the changes in plantar withdrawal response of osteoarthritis rats by dynamic plantar aesthesiometer were observed and then RT-PCR analysis was done to investigate the expression of related proteins. Results 1. ChondroT significantly decreased withdrawal response of mechanical allodynia compared with control group in all of the experimental groups (ChondroT-A, ChondroT-B, ChondroT-C). 2. ChondroT significantly reduced Bax/Bcl-2 ratio in all of the experimental groups (ChondroT-A, ChondroT-B, ChondroT-C). 3. ChondroT significantly reduced the expression of INF-${\gamma}$ compared with control group in group ChondroT-B, ChondroT-C. Conclusions This results suggest that ChondroT may be meaningful for suppressing the pain of osteoarthritis. Further study is needed to conduct a rigorous clinical research.

The roots of Paeonia lactiflora (PL) has been traditionally used as analgesic, spasmolytic and tonic in Korea, China, and Japan. As part of a search for herbal medicine to treat diabetes and obesity, we confirmed hypoglycemic effect of PL through high fat diet-induced obese and diabetic mice experiments in vivo. Treatment of ethanolic extract from PL led to a significant decrease in glucose level, which is comparable to that of an antidiabetic drug metformin. In addition, PL selectively stimulates the transcriptional activities of both peroxisome proliferator-activated receptor $(PPAR){\alpha}$ and ${\gamma}$, and inhibits enzymatic activity of protein tyrosine phosphatase 1B (PTP1B), which are predicted to be therapeutic target in treatment of type2 diabetes and obesity. Especially, the n-hexane fraction (Hx) from PL ethanol extract showed more potent activities on $PPAR{\alpha}$ and than others and exihibited moderate inhibitory activity against PTP1B.

The present study has been performed to compare the physiological analysis of monocot model plant (rice) in response to ionizing irradiations (cosmic-ray, gamma-ray, and Ion beam). Ionizing radiations were implanted into monocot model plant (rice) seed. After irradiation, the seeds were planted in the plastic pots for a growth period of one month. Thereafter, the morphological and physiological characteristics including malondealdehyde (MDA) and chlorophyll content, activities of antioxidant enzymes in irradiation samples were investigated. We are confirmed that the activity level of MDA and chlorophyll content were not changed by ionizing irradiation samples. However, the free radical contents were increased in all irradiated plants. And the activities of SOD, POD, and APX were significantly increased by irradiation compared with non-irradiation plant.

Current studies have been reported that fruits such as berries may contain both antioxidant and antitumor polyphenols that may be important in this regard. We investigated the immunostimulatory effect of fermented blueberry (Vaccinium corymbosum L.) on cyclophosphamide-induced immunosuppression in animal model. Rats were administered blueberry yeast fermented powder (BYFP) at doses 30, 100, and 300 mg/kg for 4 weeks after cyclophosphamide (Cy) treatment, respectively. The immunomodulatory effect of BYFP were measured both in vitro and in vivo, and the changes of blood components were also analyzed. We found that BYFP recovered immunosuppression-mediated decreased liver, spleen, and thymus weights as well as up regulation of white blood cell, lymphocyte, and neutrophil in blood. Moreover, BYFP up-regulated IL-2, TNF-${\alpha}$, and IFN-${\gamma}$ pro-inflammatory cytokine production compared to immune suppressed control group, respectively. According to histological studies, BYFP regenerated significantly on Cy-mediated injured spleen at the high doses (BYFP 300) comparison with Cy-treated groups (immunosuppression). Collectively, these findings suggest that BYFP may have the potential as a dietary immunostimulatory agent.

Objectives : The aim of this study is to investigate the preventive effect of Puerariae Flos ethanol extract (PE) on methionin and choline deficient (MCD)-diet-induced Nonalcoholic fatty liver disease (NAFLD) in C57BL/6J mice. Methods : In the in vivo experiments, C57BL/6J mice were divided into 4 groups; Normal group, Control group, MCD+PE 100 group, and MCD+PE 300 group. After 4 weeks, body weight, liver weight, biochemical parameters for liver function test, histological changes, reverse transcription polymerase chain reaction (RT-PCR), and Western blot were assessed. Results : Mice lost body weight with the MCD-diet and the MCD+PE 100 group and MCD+PE 300 groups lost less than the control group, though showed no statistical significance. Liver weights were decreased by the MCD diet, but MCD+PE 300 groups were increased significantly. In the liver function test, all the values were decreased with the MCD-diet, MCD+PE 100 group and MCD+PE 300 groups were increased significance. In histological findings of the livers, MCD-diet induced severe fatty accumulation in the livers, but this fatty change was reduced in the MCD+PE 100 group and MCD+PE 300 groups was inhibited respectively. In lipid accumulation factors (such as SREBP-1c, $C/EBP{\alpha}$, PPAR-${\gamma}$), MCD+PE 100 group and MCD+PE 300 groups showed inhibitory effect on liver lipogenesis by reducing associated gene expressions caused by MCD diet. Conclusions : We were able to know that Puerariae Flos ethanol extract (PE) shown hepatoprotective effects via a decrease on the hepatic lipogenesis factors in the experimental NAFLD Models.

Objective : An allergy to peanuts is a major cause of fatal food-induced anaphylaxis, with food allergies becoming an increasingly important health research issue. Food allergy as clinical entity has been recongnized for many years, although there is yet no general concord as to the incidence of this symptom.1) Methods : This study was undertaken to verify the effect of seeds of Canavalia gladiata (Jacq.) DC. extract (CGE) on the inhibition of allergic reactions using a cholera toxin and peanut extract-immunized food allergy mouse model. We determine whether the changes in rectal temperature were related to energy consumption owing to heat production in the body. Mast cell distribution and degranulation in the dermis and epidermis were observed with an optical microscope. Subsequently, Ara h1 levels in serum and interleukin (IL)-4, IL-10, and $IFN-{\gamma}$ levels in cultured supernatants of splenocytes were measured. Results : CGE treatment significantly attenuated the secretion of the Ara h1 antibody in serum and splenocytes. Ara h 1 was undetected in the cholera toxin and peanut extract-immunized food allergy mouse model. Improvement in ear tissue inflammation symptoms was the CGE experimental group. In the control group and peanut extract control group, the expression of mast cells was higher, whereas that in the CGE experimental group was significantly lower. Conclusion : CGE causes suppression in a food allergy mouse model via the inhibition of Ara h1 secretion, and might be useful for developing functional health foods.

Early detection of mild cognitive impairment can help prevent the progression of dementia. The purpose of this study was to design and validate a machine learning model that automatically differential diagnosed patients with mild cognitive impairment and identified cognitive decline characteristics compared to a control group with normal cognition using resting-state quantitative electroencephalogram (qEEG) with eyes closed. In the first step, a rectified signal was obtained through a preprocessing process that receives a quantitative EEG signal as an input and removes noise through a filter and independent component analysis (ICA). Frequency analysis and non-linear features were extracted from the rectified signal, and the 3067 extracted features were used as input of a linear support vector machine (SVM), a representative algorithm among machine learning algorithms, and classified into mild cognitive impairment patients and normal cognitive adults. As a result of classification analysis of 58 normal cognitive group and 80 patients in mild cognitive impairment, the accuracy of SVM was 86.2%. In patients with mild cognitive impairment, alpha band power was decreased in the frontal lobe, and high beta band power was increased in the frontal lobe compared to the normal cognitive group. Also, the gamma band power of the occipital-parietal lobe was decreased in mild cognitive impairment. These results represented that quantitative EEG can be used as a meaningful biomarker to discriminate cognitive decline.

Objectives : To clarify the possible effect of JS (Juglans sinensis), PCF (Psoralea corylifolia L.), and J+P(JS+PCF), we examined their influence on the development of pulmonary eosinophilic inflammation in the asthmatic murine model. Methods : All mice were immunized on two different days (21 days and 7 days before inhalational exposure) by intraperitonial injections of 0.2 ml alum-precipitated Ag containing 100 ${\mu}$g of OVA bound to 4 mg of aluminum hydroxide in PBS. Seven days after the second sensitization, mice were exposed to aerosolized ovalbumin for 30 minutes/day on 3 days/week for 8 weeks (at a flow rate of 250 L/min, 2.5% ovalbumin in normal saline) and, JS, PCF and J+P (200 mg/kg, 400 mg/kg) were orally administered 3 times per week for 8 weeks. Results : The suppressive effects of JS, PCF, and J+P were demonstrated by the accumulation of eosinophils into airways, with the reduction of eosinophils and lung leukocytes. These were correlated with the marked reduction of IL-4, IL-5, IL-13 levels in the BALF and serum. OVA-specific IgE levels were also decreased in serum and BAL from these mice. And also JS, PCF, and J+P decreased eosinophilic CCR3 and CD11b expression in lung tissue. Conclusions : These results indicate that JS, PCF, and J+P have deep inhibitory effects on airway inflammation and hyper-responsiveness in the asthmatic murine model. The suppression of IL-5, IgE, and eosinophilils and the increase of IFN-${\gamma}$ production in BALF seem to contribute to these effects. Specially, esosinophils and TNF-a in J+P combination group were significantly reduced in BALF and lung tissue. Hence, the results indicated that JS, PCF, and J+P could act as an immuno-modulator which possesses anti-inflammatory and anti-asthmatic property by modulating the imbalance between Th1 and Th2 cytokines.

Objectives : It has been recently shown that Piperis Longi Fructus (PLF) is involved in the reduction of eosinophil recruitment and production of Th2 cytokines in vivo. However, the main therapeutic mechanisms of PLF remains a matter of considerable debate. To investigate the therapeutic mechanisms of PLF, we examined the influence of PLF on regulatory T cells number, IgE, histamine production in vivo and Th1/Th2 cytokine balance in vitro. Methods : All mice were immunized on two different days (21 days and 7 days before inhalational exposure) by i.p. injections of 0.2 $m\ell$ alum-precipitated Ag containing 100 ${\mu}g$ of OVA bound to 4 mg of aluminum hydroxide in PBS. Seven days after the second sensitization, mice were exposed to aerosolized ovalbumin for 30 min/day on 3 days/week for 12 weeks(at a flow rate of 250 L/min, 2.5％ ovalbumin in normal saline) and PLF (150 mg/kg) were orally administered 3 times a week for 8 weeks. Splenocytes from C57BL/6 mice at 8 weeks of age were stimulated with anti-CD3 (1 mg/ml) plus anti-CD28 (1 mg/ml) antibody for 48hrs. IL-4 and IFN-$\gamma$ in the culture supernatants were measured by ELISA Results : The suppressive effects of PLF on asthma model were demonstrated by the increase the number of regulatory T cells and by reducing IgE, histamine production in vivo and modulation of Th1/Th2 cytokine balance. Conclusions : These results indicate that PLF has a deep inhibitory effects on asthma model mice by increase the number of regulatory T cells, and by reducing IgE, histamine production.
