Two forms of phosphodiesterase exist in the rat striatum, one with high (PDE -- I), and one with low (PDE -- II) affinity to substrate (cyclic 3',5'-AMP). The results obtained suggest that inhibition of PDE -- I activity by apomorphine or amantadine is partially related to their stimulating effect on dopaminergic system in the striatum.
大鼠纹状体中存在两种形式的磷酸二酯酶，一种对底物（环3',5'-腺苷一磷酸）具有高亲和力（PDE - I），另一种具有低亲和力（PDE - II）。所得结果表明，阿扑吗啡或金刚烷胺对PDE - I活性的抑制作用部分与其对纹状体中多巴胺能系统的刺激作用有关。
