RESUMEN

<p><b>OBJECTIVE</b>To investigate the effects of dopamine (DA) and metabolite in striatum of Parkinson's disease (PD) rats treated by bone mesenchymal stem cells (MSCs) modified by plasmid pIRESneo-EGFP-BDNF.</p><p><b>METHOD</b>pIRESneo-EGFP-BDNF was transfected to MSCs with electroporation. The rat models of PD were set up by 6-OHDA and then divided into four groups randomly, which were Sham group, PD group, BDNF group. The rotating behavior of rat models induced by apomorphine (APO) intraperitoneally which transplanting bone MSCs or MSCs modified by plasmid pIRESneo-EGFP-BDNF through cerebral lateral ventricle after 2, 4 and 8 weeks. The levels of DA, homovanillic acid (HVA), dihydroxy-phenylacetic acid (DOPAC) were measured by high performance liquid chromatography (HPLC) in striatum of each group.</p><p><b>RESULTS</b>The rotation numbers (r/min) of MSCs group or BDNF group in the 2nd, 4th and 8th week after transplanting were significantly decreased compared with that of PD group (P < 0.05). Those of BDNF group were specially significant compared with those of MSCs group (P < 0.05). The levels of DA, HVA, DOPAC and the ratios of DA/HVA, DA/DOPAC in stratum after PD rats intervened by transplanting cells through cerebral lateral ventricle after eight weeks were increased significantly in BDNF group or MSCs group while compared with PD group, especially in BDNF group.</p><p><b>CONCLUSION</b>The behavior of rat with PD was improved significantly by increasing the levels of DA and decreasing metabolic rate of DA in striatum while transplanting BDNF modified bone MSCs through cerebral lateral ventricle.</p>
