Abstract

Forty eight Sprague-Dawley male rats were divided into six groups including the control group fed standard diet, the group fed on AflatoxinB 1 (AFB 1 ) free wheat treated with ozone gas at 20 ppm for 20 min mixed with standard diet, the group fed on AFB 1 free wheat treated with ozone gas at 40 ppm for 20 min mixed with standard diet, the group fed AFB 1 -contaminated diet (2.5 mg/kg diet), the group fed on AFB 1 -contaminated wheat ozonation at 20 ppm for 20 min mixed with standard diet and the group fed on AFB 1 -contaminated wheat ozonation at 40 ppm for 20 min mixed with standard diet. The results indicated that the animals fed AFB 1 -contaminated diet alone showed a significant decrease in feed intake compared to the control group. Animals fed AFB 1 -contaminated wheat treated with ozone showed a significant improvement in feed intake and body weight compared to group fed AFB 1 -contaminated diet. In addition toanimals fed AFB 1 -contaminated diet (2.5mg/kg diet) untreated for 4 weeks showed a significant increase in levels ofthe biochemical parameters and levels of createnine and uric acid compared to the control group or the groups fed ozone treated wheat alone or the AFB 1 -contaminated wheat treated with ozone gas at 20 and 40 ppm. On the other hand animal fed on AFB 1 -contaminated wheat treated with ozone showed a significant improvement in all tested parameters. The Glutathione reduced (GSH) level decreased in animal feed on AFB 1 -contaminated wheat when compared with the control. Moreover, GSH value in animal feed on contaminated diet after ozonation was related with control group. The histological examination of the liver and kidney tissues showed the animals fed on AFB 1 free diet and treated with ozone showed a significant elimination of the harmful effects in the liver and kidney tissues
