Effects of betacyanin on SOD, CAT, GPx, GR activities and MDA content in brain of senescent mice induced by D-galactose
2% in the model group mice, betacyanin (50 or 100 mg/kg could increase the activities of SOD nearly to 76.
The responses of CAT activity to D-gal, betacyanin and VC treatments were similar to but more marked than that of SOD activity (Fig.
Betacyanin and VC treatments resulted in a significant elevation in the activities of the two enzymes.
Although the MDA-reducing effect of betacyanin was more pronounced that of VC, there were still significantly differences between the control and the two betacyanin/VC groups, meaning that the betacyanin and VC administration did not reverse the D-gal-induced membrane damage completely.
In order to examine the relationship between latency on the fifth day of the water maze test and the activities of SOD, CAT, GPx and GR and the level of MDA in mouse brain, the data obtained from different D-gal, betacyanin and VC treatments were analyzed statistically as follows:
In our study, chronic administration of D-gal impaired the performance of mice in a water maze task and the groups of mice receiving the two doses of betacyanin showed better cognitive parameters as compared to the model group (Fig.
Treatment with betacyanin for two weeks clearly improved the activities of these enzymes (Fig.
These results suggest that the oxidative damage may play an important role in the cognitive decline of the senescent mice induced by D-gal, and betacyanin action against oxidative stress to the brain may be involved in its amelioration of the impairments of learning and memory.
The present study showed that betacyanin form Porrulaca oieracea had a better ability than VC to reduce oxidative stress induced by D-gal in the way of activation of many antioxidant enzymes in aging mice, in agreement with a previous study in humans (Tesoriere et al.
