ABSTRACT
<p><b>OBJECTIVE</b>To investigate the mechanisms of Yinxing Pingchan recipe (YXPC) and its components, i.e. the components for detoxicating (A), for calming liver (B) and for dissolving blood stasis(C), in preventing and treating Parkinson's disease, and the path of its inhibition on nigrostriatal dopaminergic neuron (DAn) apoptosis in model mice of Parkinson's disease.</p><p><b>METHODS</b>Male C57BL/6J mice were divided into the normal group, the model group and four Chinese medicinal groups, that is, the YXPC group, and Group A, B and C, treated with YXPC and its components A, B and C respectively. Mouse model of Parkinson's disease was established by intraperitoneal injection with 1-methl-4-phenyl-1,2,3,6-tetrahydropyridin (MPTP). All mice were sacrificed in 2 batches at the 14th and the 28th day respectively. The activity of mitochondrial enzyme complex I, II and IV (MEC I, II and IV) in the brain of mice were measured, respectively.</p><p><b>RESULTS</b>As compared with the normal group, the activity of MEC I and IV in brain was significantly lower (P < 0.05 or P < 0.01), and that of MEC II had no obvious change in the model group. As compared with the model group, the activity of MEC I was significantly higher in YXPC group and Group C at the 14th day (P < 0.05), while the activity of MECII in Group A at the 14th day, Group B at the 28th day and Group C at both 14th and 28th day was significantly lower (P<0.05 or P<0.01). Activity of MEC IV in the four Chinese medicinal groups at the 14th day all significantly increased (P<0.05 or P<0.01), and retained at high level in Group B and Group C at the 28th day (P<0.05).</p><p><b>CONCLUSION</b>YXPC and its components can maintain the mitochondrial function by partial inhibiting the activity of its enzyme complex, preventing DAn apoptosis to slow down the progress of Parkinson's disease.</p>
