ABSTRACT
Objective:
To develop ~(99)Tc~m labeled dopamine transporter(DAT) imaging agent ~(99)Tc~m-(2?-[N,N~(,)-bis(2-mercaptoethyl)ethylenediamino]methyl,3?-(4-chlorophenyl)tropane(TRODAT-1) for evaluating changes of DAT in patients with Parkinson disease(PD).Methods:
The SD rats were divided into control group(n=5),PD models group(n=22)and generalized cerebral infarction models group(n=5).~() Unilateral smashing and injecting autothrombo into carotid artery of SD rats were used.~(99)Tc~m-TRODAT-1 distributing in normal rat striatum was observed.The uptakes in sound side and smashed side of PD rats striatum and in two sides of multiple infarction rats striatum were compared.Results:
~(99)Tc~m-TRODAT-1 distribution in normal rats striatum exhibited a obvious uptake in striatum.And PD rats results exhibited that the uptake was less in normal striatum than in smashed striatum obviously.The result of multiple infarction rats is same as normals rats.Conclusion:
~(99)Tc~m-TRODAT-1 might betaked specificly.Its imaging can provide a beneficial evidence for PD disease early diagnose.
