Non-alcoholic fatty liver induces many complications to the liver tissue and also serum related parameters. Medicinal plants are the safe therapeutic strategy for the treatment of diseases. In this regards, the present study was conducted to evaluate the effect of Tribulus terrestris L. (Zygophyllales: Zygophyllaceae) extract on non-alcoholic fatty liver in rats. In this experimental study, thirty male Wistar rats were divided into five groups (n = 6). Animals in experimental groups were received high fructose diet (70%) (HDF) daily alone or in combined with daily intraperitoneal injection of 500, 700 and 1,000 mg/kg extract of T. terrestris. Control group of rats was feed with standard chow. The serum levels of biomarkers of liver and serum lipid profiles were assessed, also histopathological examination of liver tissue done. Data were analyzed using One-way ANOVA method followed by Tukey’s post-hoc multiple comparison test and P < 0.05 was considered statistically significant. There were significant improvements for biomarkers of liver tissue (P < 0.05) and serum lipid profiles (P < 0.01) in the HFD-fed rats that were treated with T. terrestris extract compare to HFD-fed group. In addition, accumulation of lipids in hepatocytes was significantly reduced in the HFD-fed + extract administrated groups in comparison to HFD-fed rats (P < 0.01). T. terrestris extract has protective effects against non-alcoholic fatty liver by changing biomarkers of liver tissue, serum lipid profiles and histopathological anomalies of liver tissue, to normal range.

Background: Chinese herbal monomer hairy Calycosin is a flavonoid extracted from Radix astragali. Aims and Scope: The aim of the research was to investigate the effect and mechanism of Hairy Calycosin on Non-Alcoholic Fatty Liver Dieases (NAFLD) in rats. Materials and Methods: 60 rats were randomly divided into 6 groups, then NAFLD rat models were prepared and treated with different doses of Hairy Calycosin (0.5, 1.0, 2.0 mg/kg) or Kathyle relatively. Results: Both 1.0 mg/kg and 2.0 mg/kg Hairy Calycosin treatment could significantly increase the serum Superoxide Dismutase (SOD) content of the model rats and reduce the serum levels of alanine aminotransferase (ALT), aspartate aminotransferase (AST), Free Fatty Acid (FFA), IL-6, tumor necrosis factor-alpha (TNF-α) and liver homogenate malondialdehyde (MDA), while 2.0 mg/kg Hairy Calycosin can down-regulate liver tissue cytochrome p450 2E1 (CYP2E1). In the electron microscope, compared with the model control group, the mitochondrial swelling in the hepatocytes of Hairy Calycosin (1.0, 2.0 mg/kg) treatment group was significantly reduced, the ridge on the inner membrane of mitochondria increased, and the lipid droplets became much smaller. Conclusion: Hairy Calycosin can effectively control the lipid peroxidation in liver tissues of rats with NAFLD, and reduce the levels of serum TNF-α, IL-6, MDA and FFA, effectively improve the steatosis and inflammation of liver tissue, and down-regulate the expression of CYP2E1, inhibit apoptosis of hepatocytes.

Obesity is considered a systemic low-grade inflammatory state. Although the spleen is the main immune organ with a close anatomical relationship with the liver, its role in the progression of fatty liver disease remains uncertain. Therefore, we sought to clarify the functional role of the spleen in the development of steatohepatitis in high-fat (HF)-diet-induced obese rats. Male Sprague-Dawley rats were fed HF food and divided into two groups, a splenectomy (SPX) group and a sham-operation (Sham) group. The liver and abdominal white adipose tissue (WAT) were removed one and six months after surgery, and we evaluated the effects of SPX on WAT and HF-induced fatty liver. SPX rats exhibited worse dyslipidemia and inflammatory changes in WAT one month after surgery. Hepatic steatosis and inflammation were accelerated by SPX, based on the time after surgery. At one month after surgery, the tissue triglyceride content increased in SPX rats, compared with Sham controls ( P < 0.05). The liver histology also showed a worsening of steatosis in those rats. At six months after SPX, dramatic inflammatory and fibrotic changes were observed in liver tissue sections. Hepatic carnitine palmitoyltransferase-1 was suppressed at one and six months after SPX ( P < 0.05 for each). WAT and liver tissue levels of inflammatory markers such as tumor necrosis factor- α, and the expression of Kupffer cells were all increased at six months in SPX rats, compared with Sham controls ( P < 0.05 for each). Our results indicate that the preservation of the spleen contributes to the prevention of the progression of hepatic steatosis to steatohepatitis in obese rats.
