چکیده مقاله:
Parkinson’s disease is a progressive and chronic disorder of the central nervous system.Levodopa and dopaminergic agonists are not used alone, but also combined with other drugs such as benserazide. The aim of this study was to investigate the effects of levodopa and benserazide on histopathological changes in the substantia nigra, and the changes of superoxide dismutase and glutathione peroxidase enzymes in serum of the Parkinsonian rats. Materials and Methods: Twenty male Wistar rats were studied in this project.Mouses were divided into five groups: control, sham, levodopa, benserazide, levodopa and benserazide.Levodopa was administered at a dose of 10 mg / kg, benserazide at a dose of 20 mg / kg, and in the combined group, 30 mg / kg intraperitoneally (ip) were injected into the mouses. Results: The overall comparison of the five groups showed a significant difference between the groups for the level of SOD enzyme (p = 0.002). The post hoc test showed a significant difference between the combination group of levodopa and benserazide with levodopa (p = 0.035) and benserazide (p = 0.001) groups, so that the SOD level in the combinationgroup was 10.73 ± 3.1 and 15.93 ± 3.1 respectively, which was more than the previous two groups, but the level of the GPX enzyme did not show significant differences between the groups (p = 0.084). About the histopathological changes, counting the number of cells showed a significant difference between the combinational group (levodopa+benserazide) compared to the MPTP group. Conclusion: According to theresults, increasing SOD levels will neutralize oxidative stress factors and free radicals, which will improve the cell’s efficiency and survive.
