The present study examined the effects of Wasabi leaf (WL) on 45% Kcal high-fat diet (HFD)-fed mild diabetic obese mice. In particular, the hepatoprotective (i.e., liver weight, histopathology of liver, serum aspartate aminotransferase, alanine aminotransferase, and gamma-glutamyltransferase) effects of 12 weeks of continuous oral administration of 250 mg/kg metformin, and 200, 100, or 50 mg/kg WL were investigated. In addition, the hypolipidemic (i.e., serum triglyceride, total cholesterol, high-density lipoprotein-cholesterol, and low-density lipoprotein levels), hypoglycemic (i.e., glycated hemoglobin, blood glucose and insulin levels, pancreatic weight, and immunohistochemical-histopathological analysis of the pancreas), and anti-obesity effects (i.e., body weight, mean food consumption, total and abdominal body fat mass, periovarian fat weight, and histopathology of the periovarian and abdominal wall adipocytes) were monitored. The liver and general antioxidant defense systems were also assessed by lipid metabolism-related gene expression. All diabetes manifestations and related complications, including obesity and non-alcoholic fatty liver disease (NAFLD), were dose-dependently reduced after 84 days of oral treatment with metformin or each of the three dosages of WL. In particular, 50 mg/kg WL showed effective suppression effects against HFD-induced diabetes and related complications of obesity, NAFLD, and hyperlipidemia, comparable to the effects of metformin.

Hyperglycemia due to uncontrolled glucose regulation is widely known as cause of diabetes, non-alcoholic fatty liver disease (NAFLD), and other complications. NAFLD refers to a condition in which fat is excessively accumulated, whether inflamed or not, and has caused serious medical problems in recent years. The aim of this study was to explore the antihyperglycemia effects of Limosilactobacillus fermentum MG4295 (L. fermentum MG4295) in high-fat diet (HFD)-induced in vivo. We demonstrated the suitability of L. fermentum MG4295 as a probiotic by observing its stability, survivability, and proliferation under simulated gastrointestinal conditions, and safety, antibiotic susceptibility, hemolysis, and enzyme activity. The potential antihyperglycemic activity of L. fermentum MG4295 was investigated in an HFD and sugar-water-induced mouse model. Administration of this strain for 12 weeks showed an improved trend in glucose tolerance, insulin, alanine amino transferase, total cholesterol, low-density lipoprotein cholesterol, and glucagon-like peptide-1. Histopathological analysis revealed that L. fermentum MG4295 significantly reduced the histopathological scores of hepatic steatosis, inflammation, and hepatocellular hypertrophy in liver tissues and lipid content in adipose tissues. Administration of L. fermentum MG4295 upregulated IRS-1, AKT, and GLUT4 and downregulated G6Pc and PEPCK expression in liver and/or muscle tissues. Our results suggest that L. fermentum MG4295 can improve hyperglycemia. Furthermore, it can be used as a dietary functional supplement to manage blood glucose.

AbstractBackgroundNon-alcoholic fatty liver disease (NAFLD) is the main common cause of chronic liver disease. The aim of this study is to evaluate the effect of Shilajit, a medicine of Ayurveda, on the liver damage caused by NAFLD.Materials and methodsForty male Wistar rats, after being established as fatty liver models by feeding a high-fat diet (HFD, 12 weeks), were divided randomly into five groups as follows: control (standard diet), vehicle (HFD + distilled water), high-dose Shilajit (HFD + 250 mg/kg Shilajit), low-dose Shilajit (HFD + 150 mg/kg Shilajit) and pioglitazone (HFD + 10 mg/kg pioglitazone). The serum levels of aspartate aminotransferase (AST), alanine aminotransferase (ALT), triglycerides (TG), total cholesterol (TC), low-density lipoprotein (LDL), glucose and liver glutathione peroxidase (GPx), superoxide dismutase (SOD) activity, malondialdehyde (MDA) levels, liver weight, and histopathological manifestation outcomes were measured after the 2-week intervention.ResultsShilajit treatment significantly reduced the values of AST and ALT, TG, TC, LDL, glucose, liver weight, and steatosis, and instead, increased high-density lipoprotein (HDL) compared with the vehicle group (p < 0.05). Further, Shilajit treatment improved the adverse effects of HFD-induced histopathological changes in the liver as compared with the vehicle group (p < 0.001). MDA level and GPx activity increased but SOD activity decreased in the vehicle group compared with the control group (p < 0.05), while treatment with Shilajit restored the antioxidant/oxidant balance toward a significant increase in the antioxidant system in the Shilajit group (p < 0.05).ConclusionsThese findings suggest that Shilajit improved the histopathological NAFLD changes in the liver and indicated the potential applicability of Shilajit as a potent agent for NAFLD treatment.

The protozoan Trypanosoma cruzi is responsible for triggering a damage immune response in the host cardiovascular system. This parasite has a high affinity for host lipoproteins and uses the low-density lipoprotein (LDL) receptor for its invasion. Assuming that the presence of LDL cholesterol in tissues could facilitate T. cruzi proliferation, dietary composition may affect the parasite-host relationship. Therefore, the aim of this study was to evaluate myocarditis in T. cruzi-infected C57BL/6 mice—acute phase—fed a high-fat diet and treated with simvastatin, a lipid-lowering medication. Animals (n=10) were infected with 5×103 cells of the VL-10 strain of T. cruzi and treated or untreated daily with 20 mg/kg simvastatin, starting 24 h after infection and fed with a normolipidic or high-fat diet. Also, uninfected mice, treated or not with simvastatin and fed with normolipidic or high-fat diet, were evaluated as control groups. Analyses to measure the production of chemokine (C-C motif) ligand 2 (CCL2), interferon- (IFN-) γ, interleukin- (IL-) 10, and tumor necrosis factor (TNF); total hepatic lipid dosage; cholesterol; and fractions, as well as histopathological analysis, were performed on day 30 using cardiac and fat tissues. Our results showed that the high-fat diet increased (i) parasite replication, (ii) fat accumulation in the liver, (iii) total cholesterol and LDL levels, and (iv) the host inflammatory state through the production of the cytokine TNF. However, simvastatin only reduced the production of CCL2 but not that of other inflammatory mediators or biochemical parameters. Together, our data suggest that the high-fat diet may have worsened the biochemical parameters of the uninfected and T. cruzi-infected animals, as well as favored the survival of circulating parasites.

Hyperlipidemia and its associated obesity, hepatic steatosis, and NAFLD are worldwide problems. However, there is no ideal pharmacological treatment for these. Therefore, the complementary therapies that are both natural and safe have been focused. Healthy foods, such as fruit vinegar, may be one of the best choices. In this study, we made a special medicinal fruit vinegar, Schisandra fruit vinegar (SV), and examined its lipid-lowering effects and the underlying mechanisms in a high-fat diet rat model. The results showed that SV significantly reduced the body weight, liver weight, liver index, the serum triglyceride (TG), total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), free fatty acid (FFA), aspartate aminotransferase (AST), alanine aminotransferase (ALT), and malondialdehyde (MDA), increased the content of high-density lipoprotein cholesterol (HDL-C) and the activity of superoxide dismutase (SOD), upregulated the expressions of peroxisome proliferative activated receptor (PPAR-α), peroxisomal acyl-coenzyme A oxidase 1 (ACOX1), and carnitine palmitoyltransferase 1 (CPT1) proteins, increased the contents of key component of antioxidant defense NF-E2-related factor 2 (NRF2) and its downstream heme oxygenase-1 (HO-1) protein, and downregulated the expression of Kelch-like ECH-associated protein 1 (KEAP1). These results suggest that SV has weight loss and lipid-lowering effects in HFD rats, which may be related to its upregulation of the expressions of β-oxidation -elated PPAR-α, CPT1, and ACOX1 and the regulation of the expressions of antioxidant pathway-related KEAP1-NRF2-HO-1. Therefore, all these data provide an experimental basis for the development of SV as a functional beverage which is safe, effective, convenient, and inexpensive.

Purpose: To investigate the anti-hyperlipidemic effect of Caralluma edulis and  Verbena officinalis.Methods: Phytochemical analysis of crude extracts of Caralluma edulis (Ce.Cr) and Verbena officinalis (Vo.Cr) were carried out. Hyperlipidemia was induced in mice with high-fat diet (HFD, 1.25 % w/w cholesterol, 0.5 % w/w cholic acid and 10 % v/w coconut oil). All the groups, except the saline-treated group, were fed on HFD for 4 weeks (lead-in period) to induce hyperlipidemia. Thereafter, the groups were treated with varying doses of the plant extract for 2 weeks (treatment period) as well as atorvastatin (10 mg/kg) reference standard. Body weight was measured fortnightly for all groups. Total cholesterol (TC), triglyceride (TGs) and low density lipoprotein (LDL) were assayed using Merck diagnostic kits. For histopathological analysis, liver slices were fixed in 10 % formalin and embedded in paraffin wax and was examined with the aid of hematoxylin and eosin staining (H & E).Results: Caralluma edulis (Ce.Cr) contains saponins, alkaloids, tannins, phenol, glycosides, terpenoids and flavonoids while Verbena officinalis (Vo.Cr) tested  positive for the presence of alkaloids, carbohydrates, flavonoids, saponins and tannins. HFD increased total cholesterol (TC), triglyceride (TGs), low density  lipoprotein (LDL) and very low density lipoprotein (VLDL) compared to regulator diet (p < 0.001). Treatment of the animals with Ce.Cr and Vo.Cr dose-dependently (500 - 1000 mg/kg) reduced serum TC, TGs, LDL and VLDL (p < 0.05, p < 0.01, p < 0.001, vs. HFD group) and raised high density lipoprotein (HDL) (p < 0.01, vs. HFD group), similar to that observed with atorvastatin (10 mg/kg). The  anti-hyperlipidemic effects of Ce.Cr and Vo.Cr were also confirmed via liver  histopathology results, showing improved structure with no hepatocellular necrosis and fat accumulation.Conclusion: These results indicate that Caralluma edulis and Verbena officinalis  exhibit antihyperlipidemic effect; thus, the plants have therapeutic potentials for the management of lipid disorders.Keywords: Caralluma edulis, Verbena officinalis, Anti-hyperlipidemia,   Hepatocellular necrosis

The present study evaluated the effects of acid-treated rutin on hyperlipidemia and obesity in high-fat diet (HFD)-induced obese mice. The mice consumed a HFD with or without acid-treated rutin for 7 weeks. Body weight gain considerably decreased, by approximately 33%, in the acid-treated rutin (AR) and quercetin (Q) groups compared to that in the HFD group. The adipocytes’ size in epididymal fat in AR and Q groups was significantly reduced compared to that in the HFD group (p < 0.05). Treatment with AR decreased the levels of triglycerides, total cholesterol, and low-density lipoprotein cholesterol compared to the HFD group. In particular, administration of AR significantly decreased serum triglyceride (36.82 mg/dL) by 46% compared to HFD (69.30 mg/dL). The AR group also showed significantly decreased atherogenic indices and cardiac risk factors. These results suggest that deglycosylated rutin generated by acid treatment enhances the anti-obesity and hypolipidemic effects in obese mice, and provides valuable information for improving the functional properties of glycosidic flavonoids.

AbstractSulforaphane (SFN), a naturally-occurring isothiocyanate enriched in cabbage and broccoli, has been provided as food supplements to improve weight management and reduce lipid levels. However, its effects on serum lipid profiles are contradictory. In this review, a meta-analysis and systematic review of SFN on lipid reduction and weight control is assessed with mice and rats fed on high-fat diet. The effects of SFN supplementation were evaluated by weighted mean difference (WMD) in body weight (BW), liver weight (LW) and also by its effect on serum lipids. A random-effects model was applied to estimate the overall summary effect. SFN reduced BW (WMD: − 2.76 g, 95% CI: − 4.19, − 1.34) and LW (WMD: − 0.93 g, 95% CI: − 1.63, − 0.23) significantly in our ten trials. Its effects on serum total cholesterol (TC) (WMD: − 15.62 mg/dL, 95% CI: − 24.07, − 7.18), low-density lipoprotein cholesterol (LDL-C) (WMD: − 8.35 mg/dL, 95% CI: − 15.47, − 1.24) and triglyceride (TG) (WMD: − 40.85 mg/dL, 95% CI: − 67.46, − 14.24) were significant except for high-density lipoprotein cholesterol (HDL-C) component (WMD: 1.05 mg/dL, 95% CI: − 3.44, 5.54). However, species, disease model, duration, SFN dosage as well as route of administration did not explain the heterogeneity among studies. In summary, these findings provide new insights concerning preclinical strategies for treating diseases including obesity, diabetes, hypertension, non-alcoholic fatty liver disease as well as cardiovascular disease with SFN supplements.

Soybean koji refers to steamed soybeans inoculated with microbial species. Soybean fermentation improves the health benefits of soybeans. Obesity is a serious health concern owing to its increasing incidence rate and high association with other metabolic diseases. Therefore, we investigated the effects of soybean and soybean koji on high-fat diet-induced obesity in rats. Five-week-old male Sprague-Dawley rats were randomly divided into four groups (n = 8/group) as follows: (1) regular diet (RD), (2) high-fat diet (HFD), (3) HFD + steamed soybean (HFD+SS), and (4) HFD + soybean koji (HFD+SK). SK contained more free amino acids and unsaturated fatty acids than SS. In a rat model of obesity, SK consumption significantly alleviated the increase in weight of white adipose tissue and mRNA expression of lipogenic genes, whereas SS consumption did not. Both SS and SK reduced serum triglyceride, total cholesterol, and low-density lipoprotein cholesterol levels, and increased high-density lipoprotein cholesterol levels. SS and SK also inhibited lipid accumulation in the liver and white adipose tissue and reduced adipocyte size. Although both SS and SK could alleviate HFD-induced dyslipidemia, SK has better anti-obesity effects than SS by regulating lipogenesis. Overall, SK is an excellent functional food that may prevent obesity.

Alcoholic Fatty Liver Disease

Non-alcoholic fatty liver disease (NAFLD) has become a major challenge to the healthcare system. This study was designed to evaluate the effect of the triterpenoid-rich fraction (TF) from Ilex hainanensis Merr. on NAFLD. Male Sprague-Dawley (SD) rats were fed a normal diet (control) or high fat diet (NAFLD model). After four weeks, the high fat diet group was orally administrated TF (250 mg/kg) for another two weeks. High fat diet fed rats displayed hyperlipidemia and a decline in liver function compared with control. However, administration with TF could effectively improve these symptoms, as demonstrated by decreasing the plasma levels of triglyceride (p <0.05), total cholesterol (p < 0.01), low-density lipoprotein cholesterol (p < 0.05), alanine transaminase (p < 0.05), aspartate aminotransferase (p < 0.01), liver index (p < 0.05) and insulin resistance index (p < 0.05) while increasing the high-density lipoprotein cholesterol (p < 0.05). Meanwhile, histopathological examination of livers also showed that TF could reduce the incidence of liver lesions induced by high fat diet. Furthermore, TF could alleviate oxidative stress and inflammation status indicated by the decline malondialdehyde and superoxide dismutase levels (p < 0.01, both) and levels of interleukin 6 and tumor necrosis factor-α (p < 0.05). In addition, immunohistochemistry showed TF evidently elevated the peroxisome proliferator-activated receptor (PPARα) expression (p < 0.01), while it diminished the Cytochrome P450 2E1 (CYP2E1) expression (p < 0.01) in liver. These results demonstrate that TF has potential ability to protect liver against NAFLD by regulating lipids metabolism and alleviating insulin resistance, inflammation and oxidative stress. This effect might be associated with regulating PPARα and CYP2E1 expression.

Eclipta Alba has been used in traditional and folklore medicine to treat Hyperlipidemia and hepatic disorders. The present study was aimed to investigate the Antihyperlipidemic and hepatoprotective potentials of Eclipta Alba in high-fat diet -induced Albino rats and to determine the underlying mechanism.  A total of 30 adult albino rats of Wistar strain weighing 165–215 g were utilized. Animals were treated with high-fat diet for 8 weeks followed by post-treatment of E. Alba for 1 week, 2 weeks, and 3 weeks, respectively. After 12 h of fasting on the last day of the experiment, serum blood samples were collected in EDTA vials and processed for biochemical analysis.  A significant decrease in levels of total cholesterol and triglycerides was noted on animals treated with E. alba compared to high-fat diet animals. Treatment of hypercholesterolemic rats with E. Alba showed a marked decrease of serum low-density lipoprotein (LDL) and very LDL cholesterol concentrations compared to the hypercholesterolemic rats. High-fat diet feeding worsened the levels of serum glutamic oxaloacetic transaminase, serum glutamic pyruvic transaminase, and alkaline phosphatase enzymes, whereas the same markers were significantly improved by supplementation with E. alba compared to the normal group.  E. alba acts as an antihyperlipidemic agent in hyperlipidemic conditions and helps for better health.
