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 : Liver disease is an inflammatory reaction caused by oxidative stress, viral, alcohol, and drug properties. Inflammatory reaction causes hepatitis and chronic hepatitis is persistent, it progresses to liver fibrogenesis and liver cancer. The aim of this study was to confirm the hepatoprotective effect of Tongyuhwalhyeol-tang(Tongqiaohuoxue Decoction) (TH) and Gamtongyuhawlhyeol-tang(GTH) in TAA-induced liver injury animal model. Methods : The antioxidant activities were evaluated through in vitro experiments, such as 1, 1-diphenyl-2-picrylhydrazyl (DPPH) and 2, 2'-azinobis-3-ethyl-benzothiazoline-6-sulfonic acid (ABTS) radical scavenging assays, total polyphenol and total flavonoid content measurement. To confirm the liver protective effect, induced by Thioacetamide (TAA) for 3 days injection at 200 mg/kg rats. TH and GTH were treated 3 days at 200 mg/kg/day. The changes of reactive oxygen species (ROS), peroxynitrite ($ONOO^-$), alanine aminotransferanse (ALT) and aspartate aminotransferase (AST) in serum were analyzed after experiment. Also, expression of anti-inflammation, anti-oxidant related proteins were investigated by western blot analysis. Results : TH was inhibited the antioxidant activities. In the TAA-induced rat, TH decreased ROS, $ONOO^-$, ALT, AST level in serum. Inflammation related protein expressions increased in TAA-induced rat compared to normal rat. However, TH group inhibited the down expression of these proteins. Also, anti-oxidant related protein expressions increased in TH group compared TAA-induced rat. Conclusion : Therefor, these results suggested that TH provided hepatoprotective effects on the hepatic injury leading to the reduction of inflammatory response. In addition, the effect of TH was superior to that of GTH.
BACKGROUND/OBJECTIVES: Previous studies have reported that protein supplementation contributes to the attenuation of inflammation. Serious trauma such as burn injury usually results in the excessive release of inflammatory factors and organs dysfunction. However, a few reports continued to focus on the function of protein ingestion in regulating burn-induced inflammation and organ dysfunction. MATERIALS/METHODS: This study established the rat model of 30% total body surface area burn injury, and evaluated the function of blended protein (mixture of whey and soybean proteins). Blood routine examination, inflammatory factors, blood biochemistry, and immunohistochemical assays were employed to analyze the samples from different treatment groups. RESULTS: Our results indicated a decrease in the numbers of white blood cells, monocytes, and neutrophils in the burn injury group administered with the blended protein nutritional support (Burn+BP), as compared to the burn injury group administered normal saline supplementation (Burn+S). Expressions of the pro-inflammatory factors (tumor necrosis factor-α and interleukin-6 [IL-6]) and chemokines (macrophage chemoattractant protein-1, regulated upon activation normal T cell expressed and secreted factor, and C-C motif chemokine 11) were dramatically decreased, whereas anti-inflammatory factors (IL-4, IL-10, and IL-13) were significantly increased in the Burn+BP group. Kidney function related markers blood urea nitrogen and serum creatinine, and the liver function related markers alanine transaminase, aspartate aminotransferase, alkaline phosphatase, and lactate dehydrogenase were remarkably reduced, whereas albumin levels were elevated in the Burn+BP group as compared to levels obtained in the Burn+S group. Furthermore, inflammatory cells infiltration of the kidney and liver was also attenuated after burn injury administered with blended protein supplementation. CONCLUSIONS: In summary, nutritional support with blended proteins dramatically attenuates the burn-induced inflammatory reaction and protects organ functions. We believe this is a new insight into a potential therapeutic strategy for nutritional support of burn patients.

Red yeast rice, also known as Hong Qu and red Koji, has been used for a long time in Asian functional food and traditional medicine. It consists of multiple bioactive substances, which can potentially be used as nutraceuticals. Alcoholic liver disease (ALD) can range from simple steatosis or inflammation to fibrosis and cirrhosis, possibly through leaky gut and systemic endotoxemia. This study examined the liver and gut effects of red yeast rice (RYR) (Monascus purpureus) ethanol extract against binge ethanol-induced liver injury in mice. RYR extract was orally administered to C57BL/6N mice at a concentration of 200 mg/kg body weight per day for 10 days. Then, mice were administered binge alcohol (5 g/kg/dose) three times at 12 hr intervals. Binge alcohol exposure significantly elevated the endotoxin, aspartate aminotransferase (AST), and alanine transaminase (ALT) activity of plasma, as well as hepatic triglyceride levels; however, RYR treatments reduced these levels. In addition, RYR pretreatment significantly reduced the alcohol-induced oxidative maker protein and apoptosis maker in binge alcohol-induced gut and liver injuries. These results suggest that RYR may prevent alcohol-induced acute leaky gut and liver damage.

This study utilized Italian ryegrass silage (IRGS) - based total mixed ration (TMR) as feedstuff and evaluated its effects on rumen fermentation, growth performance, blood parameters, and bacterial community in growing Hanwoo heifers. Twenty-seven Hanwoo heifers (body weight [BW], 225.11 ± 10.57 kg) were randomly allocated to three experimental diets. Heifers were fed 1 of 3 treatments as follows: TMR with oat, timothy, and alfalfa hay (CON), TMR with 19% of IRGS (L-IRGS), and TMR with 36% of IRGS (H-IRGS). Feeding high levels of IRGS (H-IRGS) and CON TMR to heifers resulted in a greater molar proportion of propionate in the rumen. The impact of different TMR diets on the BW, average daily gain, dry matter intake, and feed conversion ratio of Hanwoo heifers during the growing period did not differ (p > 0.05). Furthermore, the blood metabolites, total protein, albumin, aspartate aminotransferase, glucose, and total cholesterol of the heifers were not affected by the different TMR diets (p > 0.05). In terms of rumen bacterial community composition, 264 operational taxonomic units (OTUs) were observed across the three TMR diets with 240, 239, and 220 OTUs in CON, L-IRGS, and H-IRGS, respectively. IRGS-based diets increased the relative abundances of genera belonging to phylum Bacteroidetes but decreased the abundances of genus belonging to phylum Firmicutes compared with the control. Data showed that Bacteroidetes was the most dominant phylum, while Prevotella ruminicola was the dominant species across the three TMR groups. The relative abundance of Ruminococcus bromii in the rumen increased in heifers fed with high inclusion of IRGS in the TMR (H-IRGS TMR). The relative abundance of R. bromii in the rumen significantly increased when heifers were fed H-IRGS TMR while P. ruminicola increased in both L-IRGS and H-IRGS TMR groups. Results from the current study demonstrate that the inclusion of IRGS in the TMR is comparable with the TMR containing high-quality forage (CON). Thus, a high level of IRGS can be used as a replacement forage ingredient in TMR feeding and had a beneficial effect of possibly modulating the rumen bacterial community toward mainly propionate-producing microorganisms.

Objective: To evaluate the performance of predicting early recurrence using preoperative factors only in comparison with using both pre-/postoperative factors. Materials and Methods: We retrospectively reviewed 549 patients who had undergone curative resection for single hepatcellular carcinoma (HCC) within Milan criteria. Multivariable analysis was performed to identify pre-/postoperative high-risk factors of early recurrence after hepatic resection for HCC. Two prediction models for early HCC recurrence determined by stepwise variable selection methods based on Akaike information criterion were built, either based on preoperative factors alone or both pre-/postoperative factors. Area under the curve (AUC) for each receiver operating characteristic curve of the two models was calculated, and the two curves were compared for non-inferiority testing. The predictive models of early HCC recurrence were internally validated by bootstrap resampling method. Results: Multivariable analysis on preoperative factors alone identified aspartate aminotransferase/platelet ratio index (OR, 1.632; 95% CI, 1.056-2.522; p = 0.027), tumor size (OR, 1.025; 95% CI, 0.002-1.049; p = 0.031), arterial rim enhancement of the tumor (OR, 2.350; 95% CI, 1.297-4.260; p = 0.005), and presence of nonhypervascular hepatobiliary hypointense nodules (OR, 1.983; 95% CI, 1.049-3.750; p = 0.035) on gadoxetic acid-enhanced magnetic resonance imaging as significant factors. After adding postoperative histopathologic factors, presence of microvascular invasion (OR, 1.868; 95% CI, 1.155-3.022; p = 0.011) became an additional significant factor, while tumor size became insignificant (p = 0.119). Comparison of the AUCs of the two models showed that the prediction model built on preoperative factors alone was not inferior to that including both pre-/postoperative factors {AUC for preoperative factors only, 0.673 (95% confidence interval [CI], 0.623-0.723) vs. AUC after adding postoperative factors, 0.691 (95% CI, 0.639-0.744); p = 0.0013}. Bootstrap resampling method showed that both the models were valid. Conclusion: Risk stratification solely based on preoperative imaging and laboratory factors was not inferior to that based on postoperative histopathologic risk factors in predicting early recurrence after curative resection in within Milan criteria single HCC patients.
Objective: This study aimed to evaluate the role of preoperative two-dimensional (2D) shear wave elastography (SWE) in assessing the stages of liver fibrosis in patients with suspected biliary atresia (BA) and compared its diagnostic performance with those of serum fibrosis biomarkers. Materials and Methods: This study was approved by the ethical committee, and written informed parental consent was obtained. Two hundred and sixteen patients were prospectively enrolled between January 2012 and October 2018. The 2D SWE measurements of 69 patients have been previously reported. 2D SWE measurements, serum fibrosis biomarkers, including fibrotic markers and biochemical test results, and liver histology parameters were obtained. 2D SWE values, serum biomarkers including, aspartate aminotransferase to platelet ratio index (APRi), and other serum fibrotic markers were correlated with the stages of liver fibrosis by METAVIR. Receiver operating characteristic (ROC) curves and area under the ROC (AUROC) curve analyses were used. Results: The correlation coefficient of 2D SWE value in correlation with the stages of liver fibrosis was 0.789 (p < 0.001). The cut-off values of 2D SWE were calculated as 9.1 kPa for F1, 11.6 kPa for F2, 13.0 kPa for F3, and 15.7 kPa for F4. The AUROCs of 2D SWE in the determination of the stages of liver fibrosis ranged from 0.869 to 0.941. The sensitivity and negative predictive value of 2D SWE in the diagnosis of ≥ F3 was 93.4% and 96.0%, respectively. The diagnostic performance of 2D SWE was superior to that of APRi and other serum fibrotic markers in predicting severe fibrosis and cirrhosis (all p < 0.005) and other serum biomarkers. Multivariate analysis showed that the 2D SWE value was the only statistically significant parameter for predicting liver fibrosis. Conclusion: 2D SWE is a more effective non-invasive tool for predicting the stage of liver fibrosis in patients with suspected BA, compared with serum fibrosis biomarkers.

Objective: To determine whether the values of hepatic apparent diffusion coefficient (ADC) can differentiate biliary atresia (BA) from non-BA or be correlated with the grade of hepatic fibrosis in infants with cholestasis. Materials and Methods: This retrospective cohort study included infants who received liver MRI examinations to evaluate cholestasis from July 2009 to October 2017. Liver ADC, ADC ratio of liver/spleen, aspartate aminotransferase to platelet ratio index (APRI), and spleen size were compared between the BA and non-BA groups. The diagnostic performances of all parameters for significant fibrosis (F3-4) were obtained by receiver-operating characteristics (ROCs) curve analysis. Results: Altogether, 227 infants (98 males and 129 females, mean age = 57.2 ± 36.3 days) including 125 BA patients were analyzed. The absolute ADC difference between two reviewers was 0.10 mm2/s for both liver and spleen. Liver ADC value was specific (80.4%) and ADC ratio was sensitive (88.0%) for the diagnosis of BA with comparable performance. There were 33 patients with F0, 15 with F1, 71 with F2, 35 with F3, and 11 with F4. All four parameters of APRI (τ = 0.296), spleen size (τ = 0.312), liver ADC (τ = -0.206), and ADC ratio (τ = -0.288) showed significant correlation with fibrosis grade (all, p < 0.001). The cutoff values for significant fibrosis (F3-4) were 0.783 for APRI (area under the ROC curve [AUC], 0.721), 5.9 cm for spleen size (AUC, 0.719), 1.044 x 10-3 mm2/s for liver ADC (AUC, 0.673), and 1.22 for ADC ratio (AUC, 0.651). Conclusion: Liver ADC values and ADC ratio of liver/spleen showed limited additional diagnostic performance for differentiating BA from non-BA and predicting significant hepatic fibrosis in infants with cholestasis.
People with higher genetic predisposition to obesity are more susceptible to cardiovascular diseases (CVDs) and healthy plant-based foods may be associated with reduced risks of obesity and other metabolic markers. We investigated whether healthy plant-foods-rich dietary patterns might have inverse associations with cardiometabolic risk factors in participants at genetically elevated risk of obesity. For this cross-sectional study, 377 obese and overweight women were chosen from health centers in Tehran, Iran. We calculated a healthy plant-based diet index (h-PDI) in which healthy plant foods received positive scores, and unhealthy plant and animal foods received reversed scores. A genetic risk score (GRS) was developed based on 3 polymorphisms. The interaction between GRS and h-PDI on cardiometabolic traits was analyzed using a generalized linear model (GLM). We found significant interactions between GRS and h-PDI on body mass index (BMI) (p = 0.02), body fat mass (p = 0.04), and waist circumference (p = 0.056). There were significant gene-diet interactions for healthful plant-derived diets and BMI-GRS on high-sensitivity C-reactive protein (p = 0.03), aspartate aminotransferase (p = 0.04), alanine transaminase (p = 0.05), insulin (p = 0.04), and plasminogen activator inhibitor 1 (p = 0.002). Adherence to h-PDI was more strongly related to decreased levels of the aforementioned markers among participants in the second or top tertile of GRS than those with low GRS. These results highlight that following a plant-based dietary pattern considering genetics appears to be a protective factor against the risks of cardiometabolic abnormalities.
This study was performed using animals to confirm the effect of tourmaline-ionized water (TIW) the properties of which were changed by tourmaline energy and electric discharge. In the ICR mice fed high-fat diet, body weight increasing rate of the TIW-treated group (Exp) was generally decreased and moreover exhibited significance at 11th week (P<0.05) compared with the control (Con) group fed distilled water, although water intake of the Exp group was lower than that of the Con group. In the ICR mice with $CCl_4$-induced hepatotoxicity, AST and ALT activities of the Exp group were not significant but showed some decreasing trend, and histological damage of liver was less compared with thatof the Con group. On the study of ethanol-induced hangovers in Sprague-Dawley rat, blood alcohol concentration was significantly decreased (P<0.01), activity of GST, antioxidant enzyme related to the alcohol metabolism, was increased in liver tissue (P<0.05), and AST and ALT show a tendency to be decreasedin the Exp group. These results suggest that drinking TIWhas not only some obesity preventing effect but also an alcohol detoxification effect and liver protecting effect in vivo. It is supposed due to a structural change of water cluster and a property which maintains the changed structure through tourmaline energy and electric discharge. Therefore, TIW has a potentiality to be developed as functional water with several beneficial effects as well as for daily drinking, but further study on the mechanism related with efficacy will be necessary.
