The product was identified to be L-Cysteine based on thin layer chromatography, optical rotation and HPLC studies.

酶促反应后的产物经薄层层析、旋光度法和高效液相色谱鉴定为L -半胱氨酸。

CONCLUSION: After high dose of L-dopa intervention, rotation behavior of PD rats improves, and D2 receptor is down-regulated significantly.

结论：大剂量左旋多巴干预能明显改善PD大鼠的旋转行为，并使纹状体多巴胺d2受体明显下调。

1800 relative rotation between the diffraction pattern and micrograph that would not be detectable in the double exposure technique illustrated in fig. l. 3.

图表1。3所示的双曝光技术中对于衍射模型和显微图并没有表示出来，这个倒置，就在衍射模型和显微图之间形成了一个额外的1800相关旋转。
