Epicatechin Reduces Striatal MPP⁺-Induced Damage in Rats through Slight Increases in SOD-Cu,Zn Activity

Figure 3

EC effect on striatal Ca²⁺-dependent and Ca²⁺-independent nitric oxide synthase activity. The Ca²⁺-dependent NOS activity was significantly increased after MPP⁺ treatment. The results are expressed as mean ± S.E.M. of 5–7 animals per group in ng L-citrulline/500 mg of protein/30 min. , two-way ANOVA followed by Tukey’s test.
