Exploration of D2 receptors and cotent of DA of striatum in hemi-parkinsonism model rats before and after Madopar treatment[J]. Nuclear techniques, 1998, (5): 257-261.DOI:
HPLC-ECD were used to study therelationship between D2 receptors and the content of DA
HVA
DOPAC in striatumof hemi-parkinsonism model rats before and after Madopar treatment. After Madopartreatment
the striatum/cerebellum 125I-IBZM uptake ratio of lesioned side was 7.23±0.67
showed 17.22± 3.94% increasing as compared to the contralateral side
theincreasing were significantly declined compared with the pretreatment group andcontrol group (P<0.01). The DA
HVA
DOPAC levels in lesioned side striatum ofMadopar group were increased compared with the other two groups (P<0.05). All ofthe above verified that Madopar treatment can elevate DA levels of lesioned striatumin hemi-parkinsonism model rats
and thus prevent and reverse the up-regulation ofD2 receptors.
