[Criteria of efficiency of transplantation of embryonic nervous tissue preparations in rats with 6-OHDA-impaired dopaminergic nigrostriatal system].
Effectiveness of transplantation of cells from embryonal nervous tissue of the ventral mesencephalon (VM ENT) and striatum (STR ENT) by apomorphin-induced motor asymmetry (APO-test), consolidation of the transplant (the degree of glyal reaction and amount of dopaminergic neurons) and blood serum levels of GFAP was studied for 3 months in Wistar rats with 6-OHDA-impaired dopaminergic nigrostriatal system. Marked therapeutic effectiveness was registered in VM ENT transplantation in the denervated striatum and in combined transplantation of VM ENT into the lateral cerebral ventricle simultaneously with STR ENT transplantation in the striatum. Separate transplantation of VM ENT in the lateral ventricle and STR ENT in the striatum had no positive effect on recovery of the dopaminergic nigrostriatal system. A correlation was found between the degree of glial reaction of ENT transplants, severity of rotation asymmetry and serum levels of gliofibrillary protein (GFAP). GFAP in the serum for lifetime assessment of transplant consolidation and prognosis of neurotransplantation efficiency was assayed.
