ABSTRACT
Objective To set up the Parkinson's disease(PD)rat model with pathologic characteristic of Lewy body in nigral cells.Methods SD rats were injected respectively with 8 mg Lactacystin(Lactacystin group),sodium saline(NS group)and 12 mg 6-OHDA(6-OHDA group)by stereotaxic unilateral injection into the pars compacta of substantia nigral.The spontaneous and apomorphine-induced contralateral behaviors of rats were observed.The changes of midbrain histology were viewed by microscope;expression of ?-synuclein and tyrosine hydroxylase(TH)positive cells were investigated by immunohistochemistry.The contents of dopamine and homovanillic acid in striatum were determined.Results Rats of NS group did not display abnormal behavior.The animals treated with Lactacystin developed progressively bradykinesia,hypokinesia,tremor,contralateral head tilting,and displayed apomorphine-induced contralateral rotation behavior;3 weeks later the number of TH positive cells were decreased by 83.29% compared with NS group(P
