Antioxidant and protective effect of hydroalcoholic extract of Celtis australis L. on CCl4 induced hepatotoxicity

Several human diseases including cancer, rheumatoid arthritis, and neurodegenerative and hepatic diseases are related to the destructive effect of reactive oxygen species (ROS). Antioxidants may provide a possible solution to this problem. This study was carried out to investigate the effect of hydroalcoholic extract of Celtis australis on CCl4 induced hepatotoxicity in mice. The antioxidant activity of C. australis was evaluated by 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging assay. For evaluation of hepatoprotective activity of the extract, the animals were pretreated with 200 and 400 mg/kg of C. australis extract intraperitoneally for 7 days and then received CCl4 (0.5 ml/kg in olive oil). Liver injury was determined by serum biochemical parameters such as Alanine aminotransferase (ALT), Aspartate aminotransferase (AST), Alkaline phosphatase (ALP), glutathione contents of liver tissue, and histopathological studies. A significant reduction in the serum biochemical parameters was observed when compared to the CCl4 receiving group. The standard antioxidant used in the study was ascorbic acid. C. australis extract significantly suppressed the increase in plasma activities of liver enzymes and effectively protected animals against CCl4-induced hepatic tissue damages. This study confirmed the hepatoprotective effect of the hydroalcoholic extract of C. australis.

Abstract Background: Cottonseed meal (CSM), a relatively rich source of protein and amino acids, is used as an inexpensive alternative to soybean meal (SBM) in poultry diets. Two experiments were conducted to investigate the effects of CSM on growth performance, liver redox status, and serum biochemical parameters in goslings. In experiment 1, 300 1-d-old male goslings were randomly divided into 5 groups (10 goslings/replicate, 6 replicates/group) and subjected to a 28-d experiment. In experiment 2, 240 28-d-old male goslings were randomly divided into 5 groups (8 goslings/replicate, 6 replicates/group) and subjected to a 35-d experiment. Five isonitrogenous and isoenergetic diets were formulated to produce diets in which 0% (control), 25% (CSM25), 50% (CSM50), 75% (CSM75), and 100% (CSM100) of protein from SBM was replaced by protein from CSM.Results: In experiment 1, dietary CSM was associated with linear decreases in body weight, average daily feed intake and average daily gain and linear increases in the feed-to-gain ratio and mortality from 1 to 28 d of age (P < 0.05). Increased dietary CSM was associated with linear decreases in the hydroxyl radical scavenging ability and superoxide dismutase, catalase and glutathione peroxidase activities in the liver (P < 0.05). Dietary CSM was associated with linear decreases in serum total protein, albumin, and globulin concentrations and linear increases in serum uric acid concentrations (P < 0.05). In experiment 2, the growth performance from 29 to 63 d, redox status indicators (except for malondialdehyde [MDA]) in the liver, and serum biochemical parameters at d 63 were not affected by dietary CSM concentrations (P > 0.05). The MDA content in the liver in the CSM100 group was lower than those in the other four groups (P < 0.05).Conclusion: CSM in gosling diets should not exceed 7.08% in the early growth stage (d 1 to 28), but it can be increased to 22.65% from d 29 to 63. A high concentration of CSM may reduce growth performance in 1- to 28-d-old goslings due to decreases in feed intake, liver metabolism and antioxidant capacity.
