Antioxidant Property of a Dietary Supplement of Moringa oleifera Leaves and Pleurotus ostreatus in Wistar Rats Subjected to Forced Swimming Endurance Test

摘要

The antioxidant property of Moringa oleifera leaves and Pleurotus ostreatus on swimming performance and related biochemical parameters were investigated in thirty adult male and female wistar rats. Purpose: The aim of the present study was to evaluate the antioxidant property of M. oleifera and P. ostreatus mixture in specific proportions in wistar rats. Material and Methods: The mushroom species and M. oleifera leaves were cultivated at the biotechnology laboratory of the University Cheikh Anta Diop de Dakar, Senegal. Oxidative stress in rats was induced by swimming. The dietary supplement was composed of a mixture of powders of Moringa oleifera and Pleurotus ostreatus in 2:1 ratio. Three groups received different doses of dietary supplements 500 mg/kg, 1000 mg/kg, and 1500 mg/kg, with one group being the stressed and the other the control group. Parameters in serum such as serum glutamyl oxaloacetate transaminase, serum glutamyl pyruvate transaminase, albumin, Testosterone, creatinine, and, oxidative stress parameters (catalase, reduced glutathione, and malondialdehyde) were measured. Results: Results showed that the dietary supplement has an effect on oxidative stress because it increases the activity of catalase and the level of cellular glutathione in rats. The 500 mg/kg dose would be the most appropriate dose for stressful conditions. The 1000 mg/kg dose would be the most appropriate dose for liver damage. Conclusion: This study shows that the antioxidant properties of M. oleifera leaves and Pleurotus ostreatus are demonstrated by their ability to improve body energy stores and tissue antioxidant capacity. The dietary supplement of M. oleifera leaves and P. ostreatus powders mixture could be good in stressful conditions.
