Abstract
A total of 75 adult rats were used to produce hemiparkinson^s disease (PD) model by unilateral injection of 6-hydroxydopamine (6-OHDA) into the right substantial nigra. Four weeks following the lesions, rats were tested for apomorphine (APO) -induced asymmetric rotation. Only rats that showed more than seven turns per minute were selected as PD models for transplantation. A tyrosine hydroxylase expression plasmid (pSVK3-TH) mixed with lipofectin was transplanted into the right striatum of 15 PD rats. Another 20 PD rats transplanted either with lipofectin or with pSVK3-TH served as controls. Every three days following transplantation, the perforpance of asymmetric rotation were tested and stained with the TH-immunohistochemistry. Only the animals grafted with pSVK3-TH mixed with lipofectin were found to show the decreased rotational behavior and a few TH-positive cells in the right striatum at the postgraft day 3-12, but not day 18. The results indicate that there exists a correlation between amelioration of asymmetric rotation and the TH gene expression in the denervated striatum.
