Effects Of Antioxidant From Microbe On Free Radical Metabolic, Liver Damage Repairs And Produce Performance Of Animals

The objections of this study to determine the effects of Antioxidant from microbe (AFM) on①Free radical metabolic and liver damage repairs of SD rats in experiment conditions.②Free radical metabolic and produce performance of milch cow in production conditions.Experiment1: 95 male SD rats were divided at random into 4 groups, trail 1 was blank control, and trail 2 was LPS control. Tail 3 and 4 were add AFM 0.5 and 1.0 ml/per·day with water. On the 29th day of experiment trail 2,3,4were injected LPS 3mg/Kg?WB. Results show:①on the 28th of experiment, AFM can improve the activity of SOD and GSH-Px in serum and liver(P<0.05), reduce the content of NO in serum,MDA in liver and the activity of ALT in serum(P<0.05).②After injecting LPS, the activity of SOD and GSH-Px in serum and liver was depress. on the 20h, the activity of SOD and GSH-Px was lower notability(P<0.05), and then, become recover. After 140h, the recover speed of SOD in AFM groups was well than LPS control, but GSH-Px was quite.③After injecting LPS, the content of NO and MDA in serum and liver was raise. And on the 20h, trail 2,3,4 were higher than blank...
