Objective To investigate the effect of levodopa on Parkinson's disease rats induced by 6-OHDA lesioned in different degrees. Methods Each group of PD rats whose nigrostriatal had been previously lesioned unilaterally by 6-OHDA received levodopa or saline injections twice daily for three weeks. The rotational behavior, immunohistochemistry and GSH level were observed. Results The rotational behavior ameliorated levodopa was seen only in severely lesioned PD rat. The levels of GSH in striatum were upregulated by levodopa treatment in moderately and severely lesioned PD rats. The number of tyrosine hydroxylase immunorecative neurofibers in the striatum were increased in mildly and moderately lesioned PD rats received levodopa treatment. Conclusions Levodopa upregulates the level of GSH in the striatum in moderately and severely lesioned PD rats. Levodopa will be benefical to mildly and moderately lesioned PD rats and has neurotrophic effect to promote the recovery of TH immunoreactive neurofibers in the striatum.

Objective] To explore the relationship between the pathogenesis theory of Qi and blood and stroke. [Method] The system research of ancient literature on the pathogenesis of stroke, analysis of stroke from the relationship between Qi and blood and stroke, focus on exploring the basic role of Qi and blood in the onset of stroke. [Results] Before the Tang and Song Dynasties doctors hadargument in the imaginary evilstroke pathogenesis;Jin era, that the internal gas is stroke, or qi deficiency Erzhi phlegm blockage;Ming and Qing Dynasties, many from the deficiency of Qi and Blood Stasis Theory, gas, blood throughout the stroke always. Supplementing qi and activating blood circulation method can improve the clinical symptoms of patients with stroke, stroke with Qi and blood as the pathogenesis treatment, clinical therapeutic effect. [Conclusion] Stroke syndrome differentiation from the blood, more can promote blood regulating. The stroke engine has extremely important theoretical and clinical significance from the blood, can provide a theoretical basis for the treatment of stroke in different stages, and guide the clinic, it is worth further study.
