Fig. 1From: 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 plasma total homocysteine (tHcy) concentration among the control and treated rats. Values represent mean ± SEM of tHcy (µmol/l of plasma). *P < 0.05 versus control, betaine and LD/Bet. groups. **P < 0.05 versus control, levodopa, betaine, LD/Bet. and LD/Bet.-Ben. groups.
