Fig. 6From: Beneficial antioxidant properties of betaine against oxidative stress mediated by levodopa/benserazide in the brain of ratsThe effects of levodopa, betaine and benserazide treatments on CAT activity in control and treated rats. Values represent mean ± SEM of enzyme activity (unit/mg protein of brain tissue). *P < 0.05 versus control group. **P < 0.05 versus levodopa, LD/Bet., LD/Ben. and LD/Bet.-Ben. groups.
