Fatty liver disease causes accumulation of excess fat in liver cells. Berberine has antioxidant and anti-inflammatory activities, and Sitagliptin is a DPP-4 inhibitor that increases the function of incretin hormones. In this study biological activities of Berberine and Sitagliptin for the treatment of fatty liver in diabetic Sprague-Dawley rats were investigated. The therapeutic effects of Sitagliptin and Berberine on fatty liver in diabetic rats by Alloxan injection with a single dose of 100 mg/kg were done with the following groups. Groups include 1: control (physiology serum as Alloxan solvent); 2: model (fatty liver + Alloxan); 3: Sitagliptin (fatty liver + Alloxan and Sitagliptin 10 mg/kg); 4: Berberine (fatty liver + Alloxan and Berberine 150mg/kg); 5: Berberine/Sitagliptin (fatty liver + Alloxan and Sitagliptin 5 mg/kg and Berberine 75 mg/kg). After the treatment, the liver tissue separated and weighed. Levels of Liver triglyceride, cholesterol and GLUT4 gene expression in liver tissue measured by real-time PCR method. The level of GLUT4 gene expression levels increased in the treatment groups compared to the model group, but a significant difference was seen only in the co-administration group with the model group (p < 0.05). There was a significant decrease in the amount of liver cholesterol in the treatment groups compared to the model group (p < 0.01). Hepatic triglyceride decreased in the treatment groups, but only in the co-administration group, a significant difference was seen with the model group (p < 0.05). Berberine and Sitagliptin, especially when prescribed together with the increased expression of GLUT4 and the reduction of liver cholesterol and triglycerides, have a favorable effect on lipid metabolism and can be considered as an effective treatment for hyperlipidemia and fatty liver.

Non-alcoholic fatty liver disease (NAFLD) is the most common liver dysfunction and one of the most important causes of death from chronic liver diseases. The purpose of this study is to investigate the effect of eight weeks of endurance training compared to resistance training on liver bile acids (BA), relative expression of farnesoid X receptor (FXR), fibroblast growth factor 15 (FGF15), fibroblast growth factor receptor 4 (FGFR4) and beta protein Klotho (KLB) in rats with non-alcoholic fatty liver disease. In this experimental study, 16 Wistar rats with an approximate weight of 120-160 grams, after induction of NAFLD conditions, with six weeks of high-fat diet were randomly divided into two equal groups (8 rats in each group), including; Control (C), endurance training (E). group E participated in an incremental treadmill exercise protocol with an intensity of 65% of maximal oxygen consumption and a frequency of 5 sessions per week. 48 hours after the last training session, the subjects were sacrificed and liver tissue and blood samples were taken to evaluate the research variables. Data were analyzed by using independent t-test. The findings showed that E training protocols led to a significant decrease in liver BA values (p = 0.0001). Also, in the E training group, a significant increase in the relative expression of FXR, FGF15, FGFR4 and KLB protein levels  was observed (p = 0.0001). In conclusion, it seems that endurance exercise can have positive effects on the variables involved in the signaling of bile acid synthesis.

Nonalcoholic fatty liver disease (NAFLD) is a growing health concern worldwide. Unfortunately, scientists have not succeeded in finding a suitable treatment method for this disease, and more research is needed. Studies have shown that treatment with antioxidants is effective in this disease. In this study, the effect of two different antioxidants on NAFLD induced in male Wistar rats was evaluated. This study was conducted on 32 male Wistar rats weighing 200 grams, which were randomly divided into four groups of eight. Mice were fed by gavage with high-fat emulsion at the rate of 2 mg/kg for 40 days. After suffering from fatty liver, the level of interleukin-5 (IL-5) in the serum was measured and also the expression level of STAT1 gene was determined using real-time PCR. The results showed that the level of serum IL-5 in the patient group significantly increased compared to the control group, and the treatment groups with vitamin E and propolis, significantly decreased the level of interleukin-5 compared to the patient group (p < 0.05). In addition, the greatest decrease was related to the propolis group (p < 0.05). On the other hand, the level of STAT1 gene expression in the fatty liver group is significantly increased compared to the control group (p < 0.05); Whereas, after treatment with antioxidants, the expression of this gene decreased (p < 0.05). Based on the obtained results, the use of propolis and also vitamin E as natural antioxidants by reducing the inflammatory interleukin and also reducing the expression of genes effective in the formation of NAFLD, have a promising therapeutic role in non-alcoholic fatty liver disease.

According to the widespread use of nanoparticles in medicine, the pathological study seems to be necessary. Important properties of nanoparticles are their small size. Accumulation of fat and inflammation of the liver are the beginning stage of liver cirrhosis. We aimed to determine the effect of nano-curcumin on fatty liver disease. Sixty male mice were divided into 6 groups (n=10): control, gavaged with normal food. The second group were fed cholesterol, third group were fed cholesterol and curcumin. Other groups were fed different dose of nano-curcumin. Then, lipid profile and liver enzymes were measured and liver tissues were fixed in formalin buffer, staining with hematoxylin-eosin. Data were analyzed using SPSS. Evaluation of serum cholesterol showed that treatment with curcumin significantly decreased cholesterol, TG, and LDL of plasma level. Histopathological changes of the liver in the group received cholesterol showed vacuoles of fat, in groups which were fed low doses of the nano-curcumin did not show fat vacuoles of fat. Nano-curcumin may be used in the safe doses for treatment of nonalcoholic fatty liver disease.
