| 4 | Antioxidant and antihyperlipidemic activity of Costus speciosus against atherogenic diet-induced hyperlipidemia in rabbits显示文摘Objective: An extract of Costus speciosus(CSE), a herb widely used in folk medicine, was evaluated for its antioxidant, antihyperlipidemic and ameliorating effects on histopathological changes in atherogenic rabbits.Methods: Twenty-four male rabbits(Oryctolagus cuniculus) were divided into 4 groups. Three groups were fed a diet containing 3% saturated fat and 1.3% cholesterol for 40 d. One of these was sacrificed on the 40 th day and was called the pathogenic(P) group; the other two groups received treatment for another 30 d as follows: one received 0.8 g/(kgád) of CSE and the other was given 0.01 g/(kgád) of simvastatin. The normal group was sacrificed on the 70 th day and used as a control.Results: CSE showed radical-scavenging ability. Administration of CSE for a 30-day period resulted in a significant decrease in total cholesterol, triacylglycerol, low-density lipoprotein and aspartate aminotransferase compared to the P group, while levels of hemoglobin, packed corpuscular volume and red blood cells were elevated. With respect to studies performed on the heart, a decrease in malondialdehyde and an increase in reduced glutathione were noted. Total protein increased in the liver, heart and aorta after treatment with CSE and also a marked improvement in histopathological parameters was demonstrated.Conclusion: The present findings indicate that the C. speciosus rhizome possesses antiatherogenic and antioxidant properties which may provide protective effects against oxidative stress in atherosclerotic rabbits. | Fatma Mohamed Hussein Shediwah Khalid Mohammed Naji Hussein Saleh Gumaih Fatima A Alhadi Amani Lutf Al-Hammami Myrene Roselyn D'Souza | 2019 | Journal of Integrative Medicine2019，17，3： | 0 |
