ABSTRACT
<p><b>OBJECTIVE</b>To study the effect of the Chinese compound prescription Ginkgo biloba Pingchan Recipe (GBPR) on experimental Parkinson disease (PD) in mice and explore the possible mechanism.</p><p><b>METHODS</b>Male C57/BL6J mice were divided into normal control, PD model and treatment groups. PD model was established by intraperitoneal injection with 1-methl-4-phenyl-1,2,3,6-tetrahydropyridin (MPTP) in the mice, and in the treatment group, GBPR was administered intragastrically after the injection. The mice were sacrificed 14 and 28 days later, and using in situ hybridization with Digoxin-labeled nNOS cDNA oligonucleotide probe, neuronal nitric oxide synthase (nNOS) mRNA was detected in the striatum and substantia nigra in the brain of mice.</p><p><b>RESULTS</b>nNOS mRNA expression was detected in the striatum and substantia nigra of the PD model mice, and GBPR treatment significantly reduced its expressions.</p><p><b>CONCLUSION</b>GBPR has obvious inhibitory effect against the neurotoxicity of NO probably by producing an anti-oxiditive effect through decreasing nNOS synthesis in the brain.</p>
