摘　　要：BACKGROUND： Literatures have reported that the density changes of dopamine transporter is negatively correlated with the severity degree and grading of disease condition of Parkinson disease （PD）. However, the distribution ofdopamine transporter in each nucleus of corpora striatum at each period is still unclear. OBJECTIVE： To observe the radioactive uptake distribution of dopamine transporter in bilateral corpora striata of patients with different stages of PD using single photon emission computed tomography （SPECT）, and make a comparison with healthy controls. DESIGN： Case-control analysis. SETTING： Department of Imageology, Second Hospital Affiliated to Guangzhou University of Chinese Medicine. PARTICIPANTS： Thirty patients with PD admitted to Second Hospital Affiliated to Guangzhou University of Traditional Chinese Medicine between January and December 2005 were recruited. The involved patients, 19 male and 11 female, were aged from 36 to 80 years and with disease course of 2.5 months to 10 years. They all met the clinical diagnosis criteria of Britain Parkinson＇s disease Association Think Tank; Following Hoehn-Yahr grading： grade Ⅰ ： unilateral morbidity; grade Ⅱ： bilateral morbidity, but without balance disorder; grade Ⅲ： bilateral morbidity, accompanied with early posture balance disorder; grade Ⅳ： severe morbidity, needs more help; grade V ： without help, only in bed or wheelchair. There were 11 patients with mild PD （grade Ⅰ - Ⅱ ）, 9 patients with moderate PD （grade Ⅲ） and 10 patients with advanced PD （grade Ⅳ - Ⅴ ）. Meanwhile, 6 healthy persons were selected as normal controls. Informed consents were obtained from all the subjects. METHODS： Twenty-four hours after withdrawal of PD drugs, 30 patients with PD and 6 healthy controls took kalium perchloricum 400 mg orally. After lying down for 30 minutes, all the subjects were intravenously injected with 740 MBq 99Tc m-TRODAT-1 （Jiangsu Institute of Atomic Medicine, Batch No. 20040310） at eBACKGROUND： Literatures have reported that the density changes of dopamine transporter is negatively correlated with the severity degree and grading of disease condition of Parkinson disease （PD）.
