| Research Abstract |
A recombinant adenoviral vector encoding the human glial cell line-derived neurotrophic factor (GDNF) gene was used to express the neurotrophic factor GDNF in the lateral ventricle of gerbil brain before 2 days of transient bilateral common carotid artery occlusion. Terminal deoxynucleotidyl transferase-mediated dUTP-biotin in situ nick end labeling (TUNEL) staining in pyramidal cells of hippocampal CA-1 was markedly reduced in the case with GDNF treatment at 2, 4 and 7 days of reperfusion. In GDNF treated group, pyramidal cells were well preserved in the hippocampus at 7 days after reperfusion [7.1% vs. 62.8% for vehicle and GDNF, respectively]. This results suggest that the treatment with GDNF has a significant protective effect on delayed neuronal death of hippocampal CA-1.
