Fat accumulation in the body has been implicated in the increased generation of ROS and oxidative stress which enhances hepatocellular damage. Increase in serum liver enzymes have been widely used as an index of liver dysfunction and that higher ALT concentrations predicted development of type 2 diabetes. Thirty rabbits were randomly divided into six groups, each of five animals: Group 1 = control (C), Group 2 = cholesterol diet (CD) only, Group 3 = resveratrol 200 mg/kg (R200), Group 4 = resveratrol 400 mg/kg (R400), Group 5 = CD + R200 and group 6 = CD + R400. The preparations were administered for 8 weeks of experimental protocol. Blood glucose level was measured on week zero and the 8th week of the treatment. At the end of the study period, the rabbits were placed under light anesthesia (ketamine) to remain unconscious. Blood sample of about 3ml was drawn via cardiac puncture for serum extraction which were evaluated for serum concentration of liver enzymes (alanine aminotransferase ALT, aspartate aminotransferase AST and alkaline phosphatase ALP) and oxidative stress biomarkers (superoxide dismutase SOD, catalase CAT and glutathione peroxidase GPx). Blood glucose level was significantly higher in CD group compared to groups that received resveratrol supplement. Serum Liver enzymes activities showed significant (P < 0.05) decrease in ALT, AST and ALP levels in groups that were administered resveratrol with CD compared with CD alone. Significant decrease in antioxidant enzymes activities (SOD, CAT and GPx) in resveratrol treated groups (P < 0.05) were recorded when compared to CD alone group. In conclusion, the observed decreased in blood glucose level, liver enzymes and biomarkers of oxidative stress with resveratrol administration despite CD consumptions, elucidated the therapeutic potential of resveratrol.Support or Funding Information1.

The aims of this study were to determine the modulating role of ascorbic acid (AA) on rectal temperature (RT), heterophil to lymphocyte (H to L) ratio and aberrant behaviours of ostrich chicks transported by road for 4 h during hot-dry conditions. Twenty ostrich chicks aged 2.5 months, of both sexes and belonging to the Red Neck breed, served as subjects of the study. The chicks were assigned randomly to AA-treated and control groups, consisting of 10 chicks each. The AA-treated group was administered orally with 100 mg/kg body weight of AA dissolved in 5 mL of sterile water 30 min before transportation, whilst the control group was given the equivalent of sterile water only. The thermal load (TL) experienced in the vehicle during transportation fluctuated between 31 °C and 89 °C, as calculated from the ambient temperature and relative humidity. Transportation induced hyperthermia, lymphopenia, heterophilia and aberrant behaviours of pecking, wing fluffing and panting, which were ameliorated by AA administration. The relationships between the TL, journey duration and physiological variables of RT, H to L ratio and aberrant behaviours recorded during transportation were significantly and positively correlated in the control group. In AA-treated group the relationships were not significantly correlated. In conclusion, the results showed for the first time that AA ameliorated the adverse effects of stress caused by road transportation on the aberrant behaviours, RT and H to L ratio of ostrich chicks during the hot-dry season.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
