| Abstract: |
| The effects of fermentation product of peanut meal by Bacillus natto on growth performance and antioxidant activity of aging female rats induced by D-galactose were investigated. The results showed that the serum SOD activity of rats in aging model group was significantly lower than those in normal control group(P＜0.05), and the content of MDA was significantly higher than those in normal control group(P＜0.05), indicating that the model was successful. During the experiment, the average body weight of rats in middle and high dose groups increased by 7.99% and 12.18% respectively. There was no significant difference in serum lipid enzyme among rats in each group (P>0.05), indicating that the experimental dose of HFW had no obvious damage to the liver.Compared with the aging model group, the contents of TC,TG and LDL in each HFW group decreased significantly(P<0.05), and the content of HDL increased significantly(P<0.05). The SOD activity in middle and high dose groups increased significantly(P<0.05), and the content of MDA decreased significantly(P<0.05).The middle and high dose groups had a significant increase in thymus index of rats(P＜0.05). A certain dose of HFW had a significant improvement in the body weight loss and dyslipidemia, and increased antioxidant activity in aging rats. |
