尼古尔逊博士之所以对此感兴趣, 是因为胆碱对脂肪的新陈代谢必不可少,但是狗却不能对此综合利用.
The reason for Dr Nicholson's interest was that choline is essential for metabolising fat, but dogs cannot synthesise it themselves.
目的：观察海洛因海绵状白质脑病患者的1H-MRS表现，分析其脑内N-乙酰天门冬氨酸、肌酸和胆碱的代谢规律。
OBJECTIVE: To observe the 1H-MRS manifestations of patients with heroin spongiform leucoencephalopathy so as to analyze metabolic regularities of N-acetyl aspartate, creatine and bilineurine in brain.
主要观察指标：病变部位及对侧的N-乙酰天门冬氨酸、胆碱、肌酸代谢率的测定；
