The anti-obese, hypolipidemic and hepatoprotective effects of post-fermented green tea by Monascus pilosus was tested with mice fed with high-fat diet for 7 weeks. The body weight gain and feed efficiency ratio (FER) in normal control group (NC), CHA (2% non-fermented green tea powder supplemented high-fat diet group) and mCHA (2% green tea powder post-fermented by M. pilosus supplemented high fat diet group) groups were significantly lower than those of high fat diet control group (HC). Epididymal fat weight in mCHA and NC were significantly lower than HC. The hepatic lipid peroxide was dramatically higher in HC than that of NC and was significantly lower in CHA and mCHA. In addition, dehydrogenase type activity of xanthine oxidoreductase in HC was lower than that of NC, but significantly higher than CHA and mCHA. In histopathological findings, hepatic fat accumulation in HC was higher than that of NC, CHA and mCHA. Antiobese, hypolipidemic and antifatty liver effect of green tea powder post-fermented by M. pilosus was slightly higher than that of non-fermented green tea. In conclusion, the constituents of green tea fermented by M. pilosus has been proven to not only inhibit obesity and hyperlipidemia but also decrease the hepatic fat accumulation in high fat diet-induced obese mice.

Purpose: The objective of this study was to examine whether Hamcho freeze-dried powder and Hamcho freeze-dried nano powder have an anti-obese effect on high fat diet-induced obese rats. Methods: Sprague Dawley rats were divided into 6 different groups, each of which was bred for 8 weeks with a different experimental diet: normal diet group (NC), high fat diet group (HFC), high fat diet + 2% Salicornia herbacea L. freeze-dried powder group (2% HS), high fat diet + 5% Salicornia herbacea L. freeze-dried powder group (5%HS), high fat diet + 1% Salicornia herbacea L. freeze-dried nano powder group (1% HSN), high fat diet + 2% Salicornia herbacea L. freeze-dried nano powder group (2% HSN). Results: The 5% HS group showed a weight loss effect in body weight, liver and adipose tissue by reducing the amount of dietary intake and food efficiency ratio. In addition, the 5% HS group showed a significant reduction of serum leptin concentration, while having a beneficial effect on the improvement of lipid metabolism such as increase the serum concentration of adiponectin. However, Hamcho freeze-dried nano powder did not show a weight loss effect. Conclusion: Overall data indicated that Hamcho seemed to have anti-obesity effects. In particular, consumption of 5% Hamcho freeze-dried powder might have beneficial effects on body weight, serum adiponectin level, and lipid profiles since it led to reduced body weight and growth of adipose tissues by suppressing dietary intakes. However conduct of further research studies is needed for analysis of active components and biochemical action mechanism of Hamcho.

The study was carried out to investigate the effects of chitosan-adding (0.5-1.5%) on nitrite-reduced (30 ppm) and sodium lactate-reduced (0-2%) sausages to avoid using excessively sodium lacte, which is substituted for sodium nitrite, The number of 24 rats for blood properties were used in this experiment and raised for 1-4 weeks. The color of sausages showed significant differences each treatment (p<0.05) and $a^*$ (redness) had the highest value in control (nitrite 100 ppm) and $b^*$ (yellowness) had the lowest value in T3 (nitrite 30 ppm + sodium lactate 0% + chitosan 1.5%). There were not significant differences in pH (5.53-5.66) and water holding capacity (66.06-69.75%) between control and two treatments (T1, nitrite 30 ppm + sodium lactate 2% + chitosan 0.5%; T2, nitrite 30 ppm +sodium lactate 1% + chitosan 1%), but T3 had significant differences in pH (5.06) and water holding capacity (62.44%), respectively. Springiness, cohesiveness, chewness and adhesiveness in texture analysis had not significant differences between control and three treatments, but hardness and gumminess had lower values in control than in three treatments. Appearance and color in sensory evaluation had higher values in control than in T1, but texture and flavor had lower values than in three treatments. Microbial counts had not significant differences in control, T2 and T3 for 1 week, for 3 weeks, it showed the lowest value in control than in three treatments. Anti-oxidant activity (TBARS) in sausages were more effective in control (p<0.05). The body weigh gain of rat were significantly increased in three treatments and also neutral fat, total cholesterol, LDL-cholesterol were significantly decreased in three treatments. However, T1 treatment had higher blood glucose content and significantly decreased in HDL-cholesterol, compared with control, but T2 and T3 treatments showed similar results in body weight gain and blood properties. So, through the addition of chitosan, it's possible to manufacture nitrite-reduced and sodium lactate-reduced sausage which is supplemented its function.

The anti-obesity effects of fermented black bean were tested with mice fed a high fat diet for seven weeks. Body weight gain and feed efficiency ratio (FER) in the high fat diet control (HC) group were markedly higher, compared with those of the normal control (NC) group, but were significantly lower in the 2% black bean powder supplemented high fat diet (BB) group and 2% black bean powder fermented by M. pilosus supplemented high fat diet (BBM) group, compared with those of the HC group. Food intake in the HC and BB groups was significantly lower than that of the NC and BBM groups. Water intake in the HC group was significantly lower than that of the NC group, but was higher in the BB and BBM groups, compared with that of the HC group. On the other hand, relative liver and kidney weight in the HC group was lower than that of the NC group, but was higher in the BB and BBM groups, compared with that of the HC group. In addition, whereas epididymal fat weight in the HC group was markedly higher than that of the NC group, it was significantly lower in the BB and BBM groups, compared with that of the HC group. Meanwhile, hepatic GSH in the HC group was significantly lower than that of the NC group, but was slightly higher in the BB and BBM groups, compared with that of the HC group. Although hepatic LPO in the HC group was dramatically higher than that of the NC group, it was significantly lower in the BB and BBM groups, compared with that of the HC group. In addition, serum TG, total cholesterol, and LDL-cholesterol in the HC group was significantly higher than that of the NC group, but was significantly lower in the BB and BBM groups, compared with that of the HC group. On the contrary, HDL-cholesterol in the HC group was significantly lower than that of the NC group, but was higher in the BB and BBM groups, compared with that of the HC group. In addition, activity of XOR D type in the HC group was lower than that of the NC group, but was slightly higher in the BB and BBM groups, compared with that of the NC group. Activities of ROS scavenging enzymes, such as SOD, GPX, and GST in the HC group were significantly lower than those of the NC group, but were significantly higher in the BB and BBM groups, compared with those of the HC group. In addition, serum ALT activity in the HC and BB groups was higher than that of the NC group, but was significantly lower in the BB and BBM groups, compared with that of the HC group. In histopathological findings, hepatic fat accumulation in the HC group was higher than that of the NC group, but was lower in the BBM group, compared with that of the HC and BB groups. In particular, antiobese, hypolipidemic, and antifatty liver effect of black bean powder fermented by M. pilosus was specifically higher than that of non-fermented steamed black bean. In conclusion, the constituents of black bean fermented by Monascus pilosus have been proven to not only inhibit obesity and hyperlipidemia but also decrease hepatic fat accumulation in high fat diet-induced obese mice.

Atopic dermatitis, also called congenital fever, is a allergic eczema of chronic itching disease. It is a recurrent and familial disease and appears on a wide age group from infant to adult. It is very common, and the ratio of occurrence is about $9{\~}l2\%$ of a child. However. it is showing trend of continuous increase by social and natural environment, food culture, and life style, recently. The human skin plays a barrier role against a physical and chemical stimulus from external environment. According to the latest study, the decreased amount of ceramide in horny layer impairs the bier function and moisture-maintaining function of skin in atopic dematitis patient. Ceramide is a kind of the sphingolipid in which a fatty acid is connected to sphingosin. Ceramide constitutes about $40\%$ of total lipid between keratinocytes and has the function of defense wall and building regular structure to suppress moisture vaporization in horny layer. In horny layer of skin a comified cell is composed of multi-layer structure of a brick shape, and, as for this cornified cell, it is strongly connected by ceramide, cholesterol, and free fatty acid. Here, we described the effects of a cream containing ceramide on the recovery of skin harrier function of atopic dermatitis patient. The safety and efficacy of latex and liquid formula were evaluated as cosmetics for atopic dermatitis. The latex products was composed of intercellular lipid components-ceramide, cholesterol, and free fatty acid-to restore skin barrier function in atopic dermatitis patients. The liquid one contained beta-glucan, magnolia extracts, and licolice extracts, which have skin immunomodulatory and anti-inflammatory effects. It is also confirmed that their possibility on new cosmetic market of atopic dermatitis.

The effects of ethanol extract from leaves of Eleutherococcus senticosu were evaluated on hyperlipidemic rats. Male SD rats were divided into a normal group, control (AIN-76 diet) group, Garcinia cambogia extract group, and AIN-76 diet group supplemented with ethanol extract from Eleutherococcus senticosu (EEES). The body weight of the AIN-76 group increased, whereas those of the Garcinia and EEES groups decreased. The serum total cholesterol of the AIN-76 group increased by 28.36% compared to the normal group, but decreased by only 27.15% in the Garcinia group and 25.47% in the EEES group. The serum triglyceride level of the AIN-76 group increased by 35.04% compared to the normal group, but decreased by only 26.76% in the Garcinia group and 37.54% in the EEES group. The serum HDL-cholesterol levels of the Garcinia and EEES groups increased compared to that of the AIN-76 group. The liver and epididymal adipose tissue weights of the EEES group decreased compared to those of the AIN-76 group. In measuring the concentration of triglycerides and total cholesterol level in the liver extracts, the AIN-76 group showed significant increases compared to the normal group, whereas the Garcinia and EEES groups showed a significant decrease compared to the AIN-76 group. These results indicate that the EEES group may improve lipid metabolism and reduce fat accumulation and body weight.

Objectives : The purpose of this study is to investigate Acute and Subacute Toxicity, and Anti-cancer Effect of H Herbal-acupuncture on mice and rats. Methods : Balb/c mice were injected intraperitoneally with H Herbal-acupuncture for $LD_{50}$ and acute toxicity test. Sprague-Dawley rats were experimented in the same way for subacute toxicity test. H Herbal-acupuncture was injected into abdomen of mice having S-180 cancer cell line. Result : 1. During the test, $LD_{50}$ could not be counted since there was no expired subjects. 2. In an acute toxicity test, the loss of motility and reflex action was observed, but weight increased in the treatment group, compared with those in the normal group (P<0.05). 3. In an acute toxicity test of serum biochemical values of mice, glucose increased in the treatment group II while total cholesterol was increased in the all treatment groups (P<0.05). 4. In a subacute toxicity test, a little loss of motility and reflex action was observed in the treatment group. Weight of mice in the treatment group decreased on the 28th day. 5. In a subacute toxicity test, liver weight was decreased but lung weight of mice increased in the all treatment groups (P<0.05). 6. As a result of measuring Complete Blood Count test (CBC) of rat, HCT was decreased in treatments even though it was not significant, compared with the normal group (P<0.05). 7. In a serum biochemical value test of subacute toxicity, total protein and albumin decreased in the all treatment groups. Creatinine, glucose, GOT increased in the treatment group I compared with the control group. Alkaline phos-phatase decreased in treatment II group, compared with the control group (P<0.05). 8. Median survival time that was measured in the rats treated with sarcoma-180 cancer cell Median decreased in the treatment group, compared with the control group (P<0.05). 9. Natural killer cell activity showed significant reduction at 100:1 and 10:1 E/T ratio while it increased at 50:1 E/T ratio. It is inferred that there was an error in the experiment (P<0.05). 10. In an interleukin-2 productivity test, even though it decreased in lung cancer, and increased in abdomen cancer, but it was only a small difference (P<0.005). 11. After injecting B16F10 cell into a capillary vessel of C57BL/6 mice and generating metastasized lung cancer, the lung was examined with the naked eye. It was not possible to see metastasized cancer in the all groups on the seventh day but the cancer was viewed on the fourteenth day. The number and volume of metastasized cancer in the treatment group enlarged in the treatment group, compared with the control group. Conclusion : According to the results, H herbal-acupuncture took no effects in cancer.

BACKGROUND/OBJECTIVES: Endoplasmic reticulum (ER) stress is positively associated with atherosclerosis via elevating macrophage cell death and plaque formation, in which oxidative stress plays a pivotal role. Antioxidative, lipid-lowering, and anti-atherogenic effects of kimchi, a Korean fermented vegetable, have been established, wherein capsaicin, ascorbic acid, quercetin, 3-(4'-hydroxyl-3',5'-dimethoxyphenyl)propionic acid, and lactic acids were identified. In this study, mechanisms of action of kimchi methanol extracts (KME) on fatty streak formation via suppression of ER stress and apoptosis in aorta were examined in low-density lipoprotein receptor knockout mice. MATERIALS AND METHODS: Mice fed a high cholesterol diet with an oral administration of KME (KME group, $200 mg{\cdot}kg-bw^{-1}{\cdot}day^{-1}$) or distilled water (control group) for 8 weeks (n = 20 for group). Plasma lipid and oxidative stress levels were evaluated. Protein expression was measured by western blot assay. Fatty streak lesion size and the degree of apoptosis were examined in the aorta. RESULTS: Compared to the control group, in the KME group, plasma lipids levels were decreased and oxidative stress was alleviated (P < 0.05). Protein expression levels of nuclear factor (erythroid-derived 2)-like 2-mediated antioxidants in aorta were increased whereas those for ER stress markers, glucose regulated protein 78, phospho-protein kinase RNA-like ER kinase, phospho-eukaryotic initiation factor 2 subunit ${\alpha}$, X-box binding protein 1, and C/EBP homologous protein were decreased in the KME group (P < 0.05). Moreover, apoptosis was suppressed via downregulation of phospho-c-Jun N-terminal kinase, bcl-2-associated X protein, caspases-9, and -3 with a concomitant upregulation of anti-apoptotic protein, B-cell lymphoma 2 (P < 0.05). Fatty streak lesion size was reduced and the degree of apoptosis was less severe in the KME group (P < 0.05). CONCLUSIONS: In conclusion, antioxidant activity of KME might prevent fatty streak formation through, in part, inhibition of ER stress and apoptosis in aortic sinus where macrophages are harbored.

Momordica charantia, commonly known as bitter melon, has interesting pharmacological activities such as anticancer, antiviral, antibacterial, anti-inflammatory, analgesic, and antioxidant. As supported by recent scientific reports on the beneficial effects of M. charantia, it is one of the most promising functional plants for diabetes today. In this study, we fermented the bitter melon with lactic acid bacteria and investigated the capability of controlling diabetic conditions by decreasing the blood glucose levels. After extracting the fermented bitter melon with hot water or ethanol, we tested several biological activities using mouse models. When we tested the efficacy of the glycemic control, the extracts of fermented bitter melon significantly lowered the blood glucose levels of the alloxan-induced diabetic mice. We also found that the lactic acid bacteria-fermented bitter melon protected liver damages from the treatment of alloxan monohydrates and maintained low levels of triglycerides and high levels of HDL cholesterol in these mouse models. These results suggest that our approach on fermenting bitter melon and the extracts of fermented bitter melon could lead to the possibility of the development of functional foods that contain the effectiveness of controlling blood glucose and lipid levels as well as preventing liver damages.

The anti-diabetic effect of green tea fermented by cheonggukjang was evaluated using KK-$A^y$ mice, an animal model of type 2 diabetes mellitus. Over a 90 day testing period, food and water intake decreased significantly in the group fed fermented green tea (FGT) and a group fed commercially available health functional food (PC), when compared with a diabetic control group (DC). The blood glucose levels of FGT mice were lower than in DC mice throughout the test period and were similar to the levels in PC after 60 days. Levels of Hemoglobin A1c (HbA1c) levels and insulin resistance were lower in mice of the FGT group than in mice of the DC group. DNA microarray analysis showed that administration of FGT increased the abundance of 12 mRNA transcripts related to diabetes. Whereas FGT increased hexokinase transcripts related to glycolysis more than 37 fold, levels of Pdx1 (pancreatic and duodenal homeobox1) and Cacna1e (calcium channel) transcripts increased more than 1.8 fold.
