This study was performed to investigate the effects of Cheonggukjang added with Job's tears (CAJT) on antiobesity and lipid profiles on diet-induced obese rats. Male Sprague-Dawley rats were fed high-fat diet only (A, control), and high-fat diet with Cheonggukjang powder 10% (B), CAJT powder 10% (C), Cheonggukjang powder 20% (D), CAJT powder 20% (E) for 5 weeks. Body weight gains were similar in the experimental groups, but FER was significantly lower in the group E than group A (p<0.05), and adipose tissue weights in groups with Cheonggukjang and CAJT powder were similar to those in the group A. The lengths of small intestine were significantly longer in the groups B, C, D, and E than the group A (p<0.05). Hepatic concentrations of total cholesterol (TC) and triglyceride (TG) were similar to each other. Fecal weights were not significantly different among the groups. Fecal TC concentrations were similar in the experimental groups, but fecal TG concentrations were greatly increased in the groups B, D, and E (p<0.05). The serum TC, HDL-C and LDL-C levels varied slightly among the groups, but serum TG levels were decreased in the group D and E than in the group A (p<0.05). The AI and CRF were marginally decreased in the groups B, D, and E than in the group A (p<0.05). However, blood glucose levels were not significantly different among the groups. From the findings, it had shown that Job's tears Cheonggukjang could improve lipid profiles.

Halophytes have been reported to possess a variety of physiological activities, such as anti-cancer, anti-oxidant, anti-diabetes, anti-inflammatory, and anti-obesity. Studies on the roots of the halophyte Rosa rugosa, in particular, have shown a variety of physiological activities and are known to be effective for nursing diabetic complications in traditional Korean medicine. In this study, the effect of R. rugosa on adipogenesis was investigated in 3T3-L1 pre-adipocytes treated with crude extract and solvent fractions (H₂O, n-BuOH, 85% aq. MeOH, and n-Hex) obtained from R. rugosa roots. Treatment with extract and the solvent fractions inhibited the formation of intracellular lipid droplets in differentiated 3T3-L1 adipocytes compared to the untreated group. In particular, n-BuOH and 85% aq. MeOH fractions effectively decreased the expression of adipogenic transcription factors: peroxisome proliferator activated receptor-γ (PPARγ), CCAAT/enhancer-binding protein α (C/EBPα), and sterol regulatory element-binding protein 1c (SREBP1c) in both mRNA and protein levels. In conclusion, these results suggest that R. rugosa contains anti-adipogenic molecules that can be utilized as a nutraceutical against obesity. Further refining of n-BuOH and 85% aq. MeOH fractions and analysis of their action mechanisms could yield potential therapeutic agents with anti-adipogenic effects.

The traditional Korean drink "Jehotang", which is one of the most commonly prescribed drugs for treatment of the heat stroke accompanied by high fever, severe sweat and thirst, it is effective far quenching thirst strengthening the stomach, stopping diarrhea and regulating intestinal function. It is also known to play a role in activating the growth of useful microbes in the intestine and in multiplying intestinal immune cells. Thus, this study investigated all aspects of the drink in an effort to develop a new functional beverage. In the course of this study, the analytical research into the literature concerning Jehotang an error in the secrets of preparing the drink. The Japanese apricot, which was given the botanical name, "Prunusmume", should only be used with the flesh (scientifically referred to as "Fructusmume"), which is fumigated with straw fire before drying. and the seed should be thrown away. The honey should only be used after it is heated with a gentle fire, before removing the white foam that farms on its surface to make the "Yeonmil". Two kinds of cooking processes were found in the ancient literature. One procedure boiling down the powered Fructus mume mixed with the Yeonmil, while the other procedure involved preparing the Fructus mume's water by adding water to it and blending the water with the Yeonmil and the rest of the raw ingredient before boiling them down. The current procedure, in which the cooking is done in a double boiler, has been widely adopted to its simplicity. The finished Jehotang is put in porcelain, kept at room temperature, and consumed after mixing with cold water.

This study investigated anti-diabetic activity of Kocat-D1, which is a currently used traditional medicine for treatment of diabetes in Shandong, China. Insulin sensitizing activity was observed in a cell-based glucose uptake assay using 3T3-L1 adipocytes. The treatment of 0.2 mg/mL of hot water extract of Kocat-D1 with 0.2 nM insulin was associated with a significant increasing in glucose uptake ($165.0{\pm}0.7%$) over the treatment of 0.2 nM insulin. C57BL/KsJ-db/db mice (8 weeks of age) were separated into 3 groups: normal control (control, db/+ mice untreated), diabetic control (DM control, db/db mice untreated), Kocat-D1 (db/db mice treated with Kocat-D1 extract 350 mg/kg/day). After 16 weeks of treatment, body weight and total diet intake of Kocat-D1 group were significantly lower than DM control groups. Blood glucose levels of the Kocat-D1 group ($14.7{\pm}1.4\;mmol/L$) were significantly lower compared to the DM control group ($27.1{\pm}0.2\;mmol/L$). Furthermore, insulin level was significantly increased in the Kocat-D1 group ($0.17{\pm}0.02\;ng/mL$) compared with the DM control group ($0.05{\pm}0.02\;ng/mL$). The glomeruli in kidney was stained using periodic acid-shiff base (PAS) for confirming collagen accumulation. The glomeruli in kidney of Kocat-D1 group had significantly reduced PAS-positive compared with that of DM control.

This study was conducted to compare and analyze the qualitative property of MLT (mulberry leaf tea) and FMLT (fermented mulberry leaf tea) based on the antioxidant, anticancer activities of various extracts. When the antioxidant activity of MLT and FMLT extracts was evaluated, the electron donating activity was found to increase proportionally as the concentration of each extract increased. In addition, the extract of FMLT showed a higher electron donating activity than that of MLT. Furthermore, the ethanol extracts showed the highest electron donating ability. When the SOD activity was evaluated, it was also found to increase proportionally with the concentration of each extract. Furthermore, the SOD activity of the ethanol extract group was the highest, whereas the SOD like activities of both MLT and FMLT were similar. When nitrite decomposition was evaluated for each pH, the highest value was observed at pH 1.2. Finally, the nitrite deleting ability was the highest for the ethanol extracts. When each extract of MLT and FMLT was analyzed in vitro for anticancer effects, they were found to decrease the number of cancer cells proportionally as the concentration of extract increased for both HeLa cells and MCF-7 cells. Furthermore, FMLT was found to exert a greater inhibition of cancer cells than MLT. Among the extract groups, the ethanol extract induced the greatest inhibition of the development of cancer cells, and these effects were greater against MCF-7 cells than HeLa cells.

Sea cucumber, $Stichopus$ $japonicus$, is used not only as an outstanding tonic food but also as a traditional medicine for the treatment of asthma, hypertension, rheumatism, anemia, and sinus congestion. The purpose of this study was to examine sea cucumber as an anti-gastritis and anti-gastric ulcer in HCl-ethanol-induced gastric and $H.$ $pylori$-infected animal models. Thirty 7-week-old SD rats and Mongolian gerbils were divided into normal (Nor, n=6), control (Con, 60% HCl-ethanol+water, n=6), groupI (DSCI, 60% HCl-ethanol+sea cucumber 30 mg/kg, n=6), groupII (DSCII, 60% HCl-ethanol+sea cucumber 100 mg/kg, n=6), and group III (DSCIII, 60% HCl-ethanol+sea cucumber 300 mg/kg, n=6). Sea cucumber significantly suppressed gastric lesions and ulcers in the 60% HCl-ethanol-induced gastric model. Especially, 100 mg/kg of sea cucumber showed significantly inhibitory effects. In histopathological analysis of the $H.$ $pylori$ model, we found that sea cucumber augmented the eradication rates of $H.$ $pylori$ and attenuated gastric ulcer formation. Our results suggest that sea cucumber has inhibitory effects on gastritis and gastric ulcers. In addition, sea cucumber can be applied for the treatment of $H.$ $pylori$.

The root of Adenophora triphylla is widely used as traditional herbal medicine in Korea. We studied its effects on sodium nitroprusside (SNP) cytotoxicity and antioxidant genes expression in HepG2 cells. To study whether Adenophora triphylla ethylacetate extract (ATea) inhibited NO-induced cell death, HepG2 cells were preincubated for 24 hr with 50 and 100 $\mu$g/mL ATea followed by 24-hr exposure to 0.5 mM SNP (exogenous NO donor). No-induced cytotoxicity was inhibited by pretreatment of ATea, as assessed by mitochondrial dehydrogenase activity (MTT assay). We further investigated the effects of ATea on mRNA levels of various enzymes of the antioxidant system such as Cu, Zn superoxide dismutase (SOD 1), Mn SOD (SOD 2), glutathione peroxidase (GPx), catalase and several enzymes of the glutathione metabolism [glutathione reductase (GR), $\gamma$-glutamyl-cystein synthetase (GCS), glutathione-S-transferase (GST), $\gamma$-glutamyltranspeptidase ($\gamma$-GT), glucose-6-phosphate dehydrogenase (G6PD)] by RT-PCR. CAT, GCS, GR and G6PD mRNA levels were increased after treatment with ATea. The SOD 1, SOD 2, GPx, GST and $\gamma$-GT mRNA levels were not affected in ATea-treated HepG2 cells. We concluded that ATea have an indirect antioxidant effects, perhaps via induction of CAT, GCS, GR and G6PD.

The flower of Chrysanthemum morifolium Ramat. with antioxidant, anticancer, and anti-inflammatory functions has been a widely used traditional herb as a healthy beverage and medicine. The aim of the present study was to investigate a herb tea consisting of C. morifolium Ramat., Corni fructus and Schizandra chinensis Baillon for its hepatoprotective activity against $CCl_4$-induced toxicity in freshly isolated rat hepatocytes and antigenotoxic effect against oxidative stress induced DNA damage in human leukocytes. Three different compositions of the herb tea (Mix I, II, and III) were prepared by extracting with water at $90^{\circ}C$. Freshly isolated rat hepatocytes were exposed to $CCl_4$ along with/without various concentrations of each tea. Protection of rat primary cells against $CCl_4$-induced damage was determined by the MTT assay. The significant antihepatotoxic effect of the tea was shown in Mix I and II. The increased transaminase (AST and/or ALT) release in media of $CCl_4$ treated hepatocytes was significantly lowered by all the teas tested. The effect of the tea on DNA damage in human leukocytes was evaluated by Comet assay. All teas showed a protective effect against $H_2O_2$-induced DNA damage. From these results, it is assumed that herb tea based on C. morifolium Ramat., Corni fructus and Schizandra chinensis Baillon exerted antihepatotoxic and antigenotoxic effects.

Objectives : Skin color deformation by cupping has been widely used as a diagnostic parameter in Traditional Korean Medicine(TKM). Skin color deformation such as ecchymoses and purpura is induced by local vacuum in a suction cup. Since existing studies have relied on a visual diagnostic method, there is a need to use the quantitative measurement method. Methods : We conducted an analysis of cross-polarization photographic images to assess the changes in skin color deformation. The skin color variation was analyzed using $L^*a^*b^*$ space and the skin erythema index(E.I.). The meridian theory in TKM indicates that the condition of primary internal organs is closely related to the skin color deformation at special acupoints. Before conducting these studies, it is necessary to evaluate whether or not skin color deformation is influenced by muscle condition. Hence, we applied cupping at BL13, BL15, BL18, BL20 and BL23 at Bladder Meridian(BL) and measured blood lactate at every acupoint. Results : We confirmed the high system measurement accuracy, and observed the diverse skin color deformations. Moreover, we confirmed that the $L^*$, $a^*$ and E.I. had not changed after 40 minutes(p>0.05). The distribution of blood lactate levels at each part was observed differently. Blood lactate level and skin color deformation at each part was independent of each other. Conclusions : The negative pressure produced by the suction cup induces a reduction in the volumetric fraction of melanosomes and subsequent reduction in epidermal thickness. The relationship between variations of tissue and skin properties and skin color deformation degree must be investigated prior to considering the relationship between internal organ dysfunction and skin color deformation.

The purpose of this study was to describe the perceived burden of the terminally III patients's caregiver and to analyze relationship between the perceived burden and the various demographics, illness characteristics, family relationships, and economic factor of the family & patients. The sample of 132 caregivers who care for the terminally III patients Kyung-Gi province, Seoul, Korea. The period of this study was from August to September, 2002. The perceived burden of the family caregiver was measured by the burden scale(20 items, 4 point scale) developed by Montgomery et al. (1985). The Data was analyzed using SAS-program by t-test and ANOVA. The results were as follows; 1. The mean of the family caregiver's burden score was 3.02. The score showed that caregivers perceive severe the level of burden. The hight items of the family caregiver's burden were' I feel it is painful to watch patient's diseases'(3.77). 'I feel afraid for what the future holds for my patients'(3.66), 'I feel it reduced to amount of privacy time'(3.64). 2. The caregiver's burden was significantly related to patient's gender(F=3.17, p= 0.0020), patient's job(F=2.49, p=0.0476), caregiver's age(F=4.29, p=0.0030), and caregiver's job(F=2.49, p=0.0476). 3. The caregiver's burden according to illness characteristics showed no significant difference. 4. The caregiver's burden was significantly associated with patient's family relationship (F=4.05, p=0.0041), patient's care mean period in a day(F=47.18,
