AbstractThe current study was conducted to evaluate the protective effects of Panax ginseng extract (PGE)against the toxicity and oxidative stress in rats fed aflatoxin (AFs) and/or fumonisin (FB)-contaminateddiet. Eighty female Sprague-Dawley rats were divided into eight experimental groups included thecontrol group, the group treated orally with PGE (0.5 mg/kg b.w.) and the groups fed AFs (1.4 mg/kg diet) and/or FB (20 mg/kg b.w.) contaminated diet alone or plus PGE for 11 weeks. Blood, liverand kidney tissue samples were collected at the end of treatment period for biochemical andhistological studies. The results indicated that PGE increased super oxide dismutase (SOD) levelin liver; however, the other parameters were comparable to controls. Animals fed AFs and/or FBcontaminateddiet showed a significant increase in serum biochemical parameters and oxidativestress markers accompanied with a significant decrease in antioxidant parameters levels and asevere histological changes in the liver tissue. These changes were more pronounced in the groupfed AFs plus FB. PGE succeeded to induce a significant improvement in all biochemical parametersand the histological picture towards the control although it did not normalize them. It could beconcluded that PGE is a promise candidate against the exposure to multi-mycotoxins in food.
