Liver tissue samples were taken by biopsy from Holstein cows in advanced stages of gravidity and in early lactation for pathological-histological examinations. Lipid content in hepatocytes was determined using the stereometric method by calculating volume density, and of glycogen using semi-quantitative microscopic examination of sections stained according to the method of Best. Pathological-histological examinations of liver tissue samples in healthy animals, gravid or peripartal cows did not reveal lipid infiltration or cell degeneration, and hepatocytes were completely or partly filled with glycogen. In ketotic cows, pathological-histological examinations of liver tissue samples showed lipid infiltration and hepatocyte degeneration of different intensity. In only one ketotic cow, we determined a slight degree of lipid infiltration, there was a medium degree of lipid infiltration and degeneration in six cows, and three cows were found to have a grave form of fatty liver. The quantity of glycogen in hepatocytes is in negative correlation with the degree of lipid infiltration and degeneration. In severe cases of fatty liver, glycogen is completely absent from hepatocyte cytoplasm.

Abomasal Displacement

The main aim of the present field study was to evaluate various haematological parameters in cows with left abomasal displacement (LDA) and concurrent hepatic lipidosis (fatty liver) of different severity. A further objective was to compare these haematological values among animals with concurrent LDA and fatty liver that finally died or recovered. Sixty eight Holstein dairy cows with LDA and 110 control cows were included in the study. Blood and liver biopsy samples were obtained during standing LDA surgery. Liver tissue was examined histologically and classified according to the severity of fatty liver. Haematological analysis and biochemical determination of total lipids and triglycerides concentration of liver tissue were performed. The majority of the haematological parameters evaluated were within normal range. Haematocrit and haemoglobin median values were significantly lower in all LDA cows compared to controls, but no difference was recorded among fatty liver severity groups. Haematological parameters showed no significant difference in animals that finally died compared to the ones that recovered. Haematological parameters were not significantly influenced by the concurrence of LDA and fatty liver in dairy cows.

Alcoholic Fatty Liver

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.
