Background: Non-alcoholic fatty liver disease (NAFLD) is a chronic liver disease associated with multiple metabolic disorders. The medicinal plant Curcuma longa L. is widely distributed in Asia and has been used to treat a spectrum diseases in clinical practice. To date, there are inadequate reports of the effects of C. longa 50% EtOH extract (CE) on NAFLD. Therefore, in this study, we evaluate the CE on an NAFLD animal and elucidate the mechanism of action. Methods and Results: C57BL/6J mice fed a methionine-choline deficient diet (MCD) were treated with CE or milk thistle, and changes in inflammation and stetosis were assessed. Experimental animals were divided into six group (n = 10); Normal, MCD, MCD + CE 50 mg/kg/day (CE 50), MCD + CE 100 mg/kg/day (CE 100), MCD + CE 150 mg/kg/day (CE 150), and the Control, MCD + Milk thistle 150 mg/kg/day (MT 150). Body weight, liver weight, liver function, and histological changes were assessed in experimental animals. Quantitative real-time polymerase chain reaction and western blot analyses were performed on samples collected after 4 weeks of treatment. We observed that CE administration improved MCD-diet-induced lipid accumulation, and triglyceride (TG) and total cholesterol (TC) levels in serum. Treatment with CE also decreased hepatic lipogenesis through modulation of the sterol regulatory element binding protein-1 (SREBP-1), CCAAT-enhancer binding protein α (C/EBPα), fatty acid synthase (FAS), and peroxisome proliferator-activated receptor γ (PPARγ) expresion. In addition, the use of CE increased adenosine monophosphate-activated protein kinase (AMPK) phosphorylation and inhibited the up-regulation of toll-like receptor (TLR)-2 and TLR-4 signaling and the production of inflammatory mediators. Conclusions: In this report, we observed that CE regulated lipid accumulation in an MCD dietinduced NAFLD model by decreasing lipogenesis. These data suggeste that CE could effectively protect mice against MCD-induced NAFLD, by inhibiting the TLR-2 and TLR-4 signaling cascades.

Objectives : Obesity is caused by the excess accumulation of fat in the body due to energy imbalance, and it causes various diseases. The aim of this study was to investigate an anti-obesity efficacy and an antioxidant activity of water from herbal mixture extract (SM17). Methods : The antioxidant activities were evaluated through radical scavenging assays using 1,1-diphenyl-2-picrylhydrazyl (DPPH) and 2,2'-azino-bis (3-ethylbenzothiazoline-6-sulphonic acid) (ABTS) radicals. To evaluated anti-obesity effect of SM17, we used a high fat diet fed mouse model. The SM17 (150 mg/kg body weight/day, p.o.) was treated every day for 6 weeks to C57BL/6 mice. Body weight and food intake were measured every day. The changes of reactive oxygen species (ROS), alanine aminotransferanse (ALT), aspartate aminotransferase (AST), triglycerids (TG) and total cholesterol (TC) in serum were analyzed after experiment. Also, expression of lipid metabolism related proteins were investigated by western blot analysis. Results : It was effective in antioxidant measurements, SM17 administration inhibited the biomarkers of lipid metaboism in serum and tissues. The administration of SM17 showed a significant reduction of body and tissue weight. Morever, it decreased ROS, ALT, AST, TG and TC in serum, compared with those of the obese mice. Adipogenesis-related protein expressions increased in obese mice compared to normal mice. However, SM17 group exhibited the down-expression of these proteins. Conclusion : A SM17 aqueous extract has a great effect on the stimulation (AMPK) activation, and may have a benefit to reduce a fatty acid metabolism through inhibition of lipid accumulation.
Objectives : This study was carried out to identified the effects of distilled cultivated wild ginseng pharmacopuncture to the obesity. Methods : Cultivated wild ginseng pharmacopuncture was administered on the points of chung-wan(CV12), $Ch'{\breve{o}}nch'u$(ST25), and Chok-samni(ST36) on lowering lipid and oxidative capacity in biochemical and molecular biological aspects were investigated in obese rats fed with high fat diet. Results : 1. The contents of plasma ${\beta}-lipoprotein$ showed a tendency to decrease in the pharmacopuncture groups compared to the control group. In the pharmacopuncture groups, the values of ST25 and ST36 pharmacopuncture groups showed lower value. 2. The contents of plasma free fatty acids showed a tendency to decrease in pharmacopuncture groups compared to the control group. However, in the pharmacopuncture groups, the values were not significantly different. 3. Plasma triglyceride and glucose showed lower value in the ST25 pharmacopuncture groups compared with the other groups. 4. The activity of AST showed a tendency to decrease in the pharmacopuncture groups. However, the activity of ALT was not significantly different in all the treatment groups. 5. Plasma total cholesterol and LDL-cholesterol showed lower value in the ST25 and ST36 pharmacopuncture groups and HDL-cholesterol showed higher value in the CV12 pharmacopuncture groups than that of the other treatment groups. 6. Liver total cholesterol values didn't show significant difference in all the treatment groups, and triglyceride showed lower value in the pharmacopuncture groups. 7. The contents of plasma TEARS showed lower value in the ST25 pharmacopuncture group and contents of liver TBARS showed a tendency to decrease in the pharmacopuncture groups. However these values didn't show significant difference in the pharmaco puncture groups. 8. Liver super oxide dismutase activity showed higher value in the ST25 and ST36 pharmacopuncture groups, and the value of liver glutathione peroxidase and catalase activity showed a tendency to increase in the pharmacopuncture groups. However, these values showed no significant difference in the pharmacopuncture groups. 9. Expression of apo-B and E mRNA in liver cells was lower in the ST25 pharmacopuncture group than that of the other treatment groups. However, expression of $TNF-{\alpha}$ and leptin mRNA in adipose cell showed no difference among all the treatment groups. 10. ST25 pharmacopuncture group showed a good histological character of liver. It showed similar to that of normal group. However other treatment groups and control group showed slight vasodilation and slight fat accumulation. Conclusion : These results indicate that distilled cultivated wild ginseng pharmacopuncture suppressed adipose tissue mass and lipid peroxidation, and increased antioxidant capacity.
This study was performed to investigate the effect of desalinated underground seawater (named as 'magma seawater', MSW) of Jeju Island in Korea on lipid metabolism and antioxidant activity. MSW was collected from underground of Han-Dong in Jeju Island, and freely given to high fat diet (HFD)-fed C57BL/6 mice for 10 weeks. Although there were no significant differences in the body weight changes and plasma lipid levels, hepatic triglyceride levels were significantly lower in the MSW group than in the normal tap water (TW)-drunken control group. Furthermore, the activity of fatty acid synthase (FAS) was significantly decreased and carnitine palmitoyltransferase (CPT) activity was increased in MSW group compared to TW group. Similarly, real-time PCR analysis revealed that mRNA expressions of lipogenic genes were lowered in MSW groups compared to the control group. In a morphometric observation on the liver tissue, accumulation of fats was remarkably reduced in MSW group. Meanwhile, in vitro assay, tree radical scavenging activity measured by using diphenylpicrylhydrazyl (DPPH) was increased in MSW group. The 2'-7'-dichlorofluorescein diacetate (DCF-DA) staining followed with fluorescent microscopy showed a low intensity of fluorescence in MSW-treated HepG2 cells, compared to TW-treated HepG2 cells, which indicated that the production of reactive oxygen species by tert-butyl hydroperoxide (t-BHP) in HepG2 cells was decreased by MSW treatment. The antioxidant effect of MSW on t-BHP-induced oxidative stress in HepG2 cells was supported by the increased activities of intracellular antioxidant enzymes such as catalase and glutathione reductase. From these results, we speculate that MSW has an inhibitory effect on lipogenesis in liver and might play a protective role against cell damage by t-BHP-induced oxidative stress.
Nutrient utilization and plasma level of minerals were studied in lactating crossbred cows fed diet supplemented from different source of minerals. Twelve crossbred cows of first to third lactation during their mid stage of lactation were distributed equally under two groups and were fed concentrate mixture, green fodder (para grass) and finger millet straw as per requirement. Cows in group I were fed concentrate mixture supplemented with 1% mineral mixture whereas cows in group II were not supplemented with mineral mixture in the concentrate mixture but were offered additional quantity of green fodder (1 kg DM/cow/day) to compensate for the requirement of minerals. Balance study conducted towards the end of 120 days of feeding experiment indicated that the total dry matter intake in both the groups did not differ significantly. The cows in group II offered additional quantity of green fodder consumed significantly (p<0.05) more of green fodder (5.11 vs. 4.51 kg /animal/day) and the cows in group I consumed significantly (p<0.01) more of finger millet straw (1.71 vs. 0.92 kg/animal/day). The digestibility of major nutrients did not differ between the groups except for ether extract which was significantly (p<0.05) lower in cows fed additional green fodder. The total daily intake of P, Cu, Fe and Co did not differ significantly in both the groups whereas significantly higher intakes of Ca, Mg, Zn and Mn were observed in cows supplemented with inorganic source of minerals. However, supplementation through both the sources could meet the mineral requirement in group I and group II. The gut absorption (%) of all the minerals was comparable between the groups except for Mg which was significantly (p<0.05) higher in cows supplemented mineral mixture. The net retention of all the minerals was significantly more in the group supplemented with inorganic source of minerals. Except for P, Mg and Co the retention as percentage of total intake was comparable for all minerals in both the groups. Irrespective of source of mineral supplementation the average monthly blood plasma mineral levels (Ca, P, Mg, Cu, Zn, Fe) were within the normal range and comparable between the groups. Lower level of Cu observed at the start of the experimental feeding in both the groups increased with the advancement of supplemental feeding. The plasma Zn and Fe content in cows of both the groups did not vary. The blood plasma level of some minerals (Ca, P, Mg and Cu) was significantly higher towards the end of experimental feeding as compared to the initial values due to the reduction in milk yield with advancement of lactation or due to supplemental effect of minerals. It could be concluded that supplementation of minerals through inorganic source is better utilized in terms of retention as compared to green fodder (para grass), which is a moderate source of most nutrients.
The purpose of this study was to determine to which differences in the source of protein (soy vs casein) and of isoflavones in soy protein are responsible for differential effects of bone mineral density and bone mineral content. Thirty 21-d-old Sprague-Dawley young rats were divided into 3 groups: the control group was find a casein-based diet, the soy concentrate group was fed soy protein with totally reduced isoflavones content (isoflavone 0.07 mg/g protein), and soy isolate group was fed with a higher isoflavone content (isoflavone 3.4 mg/g protein) than normal. The animal was scanned to determine the BMD and BMC using dual energy X-ray absorptiometry (DEXA, Lunar Corporation, Madison, WI). The soy concentrate group had significantly higher total body calcium/weight and total mineral content/weight than the casein group. The soy isolate group had significantly greater total bone mineral density/weight, spine bone mineral density/weight, and femoral bone mineral density (in g/$\textrm{cm}^2$ than the control and soy concentrate group. The findings of this study suggest that soy protein and isoflavones in soy protein are beneficial for bone-formation in growing male rats. Therefore exposure to these soy protein and isoflavones early in life may have long-term health benefits for bone diseases such as osteoporosis.
Background: Elevated testicular temperature disrupts spermatogenesis and causes infertility. In the present study, the protective effect of enzymatically biotransformed Panax ginseng Meyer by pectinase (GINST) against chronic intermittent heat stress-induced testicular damage in rats was investigated. Methods: Male Sprague-Dawley rats (4 wk old, 60-70 g) were divided into four groups: normal control (NC), heat-stress control (HC), heat-stress plus GINST-100 mg/kg (HG100), and heat-stress plus GINST-200 mg/kg (HG200) treatment groups. Each dose of GINST (100 mg/kg and 200 mg/kg) was mixed separately with a regular pellet diet and was administered orally for 24 wk. For inducing heat stress, rats in the NC group were maintained at $25^{\circ}C$, whereas rats in the HC, HG100, and HG200 groups were exposed to $32{\pm}1^{\circ}C$ for 2 h daily for 6 mo. At week 25, the testes and serum from each animal were analyzed for various parameters. Results: Significant (p < 0.01) changes in the sperm kinematic values and blood chemistry panels were observed in the HC group. Furthermore, spermatogenesis-related molecules, sex hormone receptors, and selected antioxidant enzyme expression levels were also altered in the HC group compared to those in the NC group. GINST (HS100 and HS200) administration significantly (p < 0.05) restored these changes when compared with the HC group. For most of the parameters tested, the HG200 group exhibited potent effects compared with those exhibited by the HG100 group. Conclusion: GINST may be categorized as an important medicinal herb and a potential therapeutic for the treatment of male subfertility or infertility caused by hyperthermia.
This study was conducted to establish the effects of subjective body-forming perception on weight-controlling behavior and weight loss, and to suggest the need for proper information and education. Using the data from the National Health and Nutrition Examination Survey conducted in the 6th period (2013-2015), 6,238 women aged 19 and over who have a body mass index of $18.5-25kg/m^2$ were analyzed. As a result, the higher the level of education and income level, the higher they were perceived to be obese, the more they chose to lose exercise and diet in order to lose weight across the board. The weight loss effort rate was higher in the obese body type recognition group, but the body weight type was the highest in the one year body weight change group (p < .001). As a result, subjective perception of body shape affected not only weight control behavior but also weight change (p < .001). Accordingly, it is necessary to have a systematic education on healthy weight-controlling behaviors, proper body image, and healthy body type recognition.

Objectives: The study investigated constipation in male and female high school students and in order to provide data base for development of education and intervention programs aimed at preventing and managing constipation in high school students. Methods: The study used a technique of convenience sampling to mobilize the entire students in an academic high school in D region. Of the combined 360 copies of questionnaire distributed, 340 copies were collected and used for the final analysis. The gathered data were analyzed using frequency, percentage, and ${\chi}^2-test$ in SPSS 21. Results: The ratio of female students with constipation is significantly higher than that of male students with the condition(${\chi}^2=5.73$, p=0.017), and there were significant differences in exercise habits(${\chi}^2=26.75$, p<0.001), eating habits(${\chi}^2=43.19$, p<0.001), and bowel habits(${\chi}^2=22.96$, p<0.001) between female students and male students. Also there was significant difference in water intake between the normal group and the constipation group(${\chi}^2=10.01$, p=0.040). Significant differences between the two groups were also discovered in the level of perception of constipation(${\chi}^2=98.76$, p<0.001), bowel movement time(${\chi}^2=15.74$, p=0.008), and use of laxatives(${\chi}^2=17.68$, p<0.001) and enema(${\chi}^2=16.97$, p<0.001) for constipation relief. Conclusions: To prevent and manage constipation in high school students, education about healthy dietary, and bowel habits is required. Also there is an urgent need to improve the school toilet environment in order to respect the rights of students to void or defecate when necessary, a process which will require involvement of students, teachers, and other school staff.
Epidemiological and experimental studies provide evidences that diet and intestinal microflora play an important role in colon carcinogenesis. In recent years, it has been suggested that lactic acid bacteria (LAB) used to ferment dairy products have an inhibitory effect on the colon cancer. This study was designed to determine the effect of Bifidobacterium longum HY8001 (Bif) and Lactobacillus acidophilus HY2104(Lac) of Korean origin on azoxymethane (AOM)-induced colonic preneoplastic lesions such as aberrant crypt foci(ACF) formation and cecal pH. At five weeks of age, Spraque-Dawley rats were divided at random into four (AOM alone, Bif, ,Lac, and Bif+Lac) groups. Animals were weighed weekly and oral administration of LAB cultures were performed daily until the termination of the study. Two weeks later, all animals were given a subcutaneous injection of AOM dissolved in normal saline at a dose of 15 mg/kg of body weight once per week for 2 weeks. All rats were necropsied 7 weeks after the last AOM injection , and the ACF were visualize under light microscopy in the formalin-fixed, unsectioned methylene blue-stained colons. The total number of aberrant crypt in Bif, Lac, and Bif+Lac groups were significantly lower than that of the AOM alone group and the percentage of inhibitions weas 35.0, 45.6%, respectively. Significant inhibition (p<0.001) in the total number of ACF was also observed in LAB treated groups (Bif , Lac, and Bif+Lac group by 3003, 38.6, and 41.2%, respectively). Furthermore, cecal pH appeared to significantly decrease by LAB administration. The results of present study provide some evidences for potential colon tumor-inhibitory properties of lactic cultures and fermented dairy products.
