ABSTRACT
Parkinson's disease (PD) is the second leading neurodegenerative disease after Alzheimer's disease. Mucuna pruriens (L.) DC. (MP) is a plant that contains Levodopa (L-DOPA) and has been known to improve the symptoms of PD. In this preliminary study, we investigated the anti-parkinsonian potential of MP to compare the effects of L-DOPA. We first developed an in vivo model of the PD in C57BL/6 male mice using rotenone. A total of twelve mice were used for this experiment. Nine mice were injected with rotenone (28 mg/kg) daily for 28 days. The mice experiments were performed to validate the effectiveness of MP to treat PD. Synthetic L-DOPA in a ratio of 120 with MP was used as MP contains 5% L-DOPA by weight in it. MP and L-DOPA were injected for 19 days on a daily basis. Cognitive function was evaluated using beam balance and olfactory tests. Serum analysis was performed using serum enzyme-linked immunosorbent assay (ELISA) analysis test. IL-12, IL-6, and TGF-ß 1 were evaluated to validate the PD inducement and treatment. The levels of IL-12, IL-6, and TGF-ß1 (p < 0.0001) in the PD mice group were significantly higher than those in the control group. The PD mice also showed higher latencies in beam balance and olfactory tests (p < 0.0001) compared to the control group. Both MP and L-DOPA-treated groups showed alleviation in latencies in beam balance and olfactory tests and decreased neuroinflammation in ELISA analysis (p < 0.001). The results treated by MP and L-DOPA showed insignificant differences in their values (p > 0.05). This proved that the MP and L-DOPA had similar effects in improving the symptoms of PD when used in the ratio of 120. Furthermore, both MP and L-DOPA reduced the level of IL-6 and TGF-ß1 in this study. It may be inferred that a reduction in the level of IL-6 and TGF-ß1 eventually leads to a reduction in the Th17 cells. The pathogenic Th17 is thought to be present in virtually all chronic inflammatory disorders. This can be an interesting area of research in further understanding the immunological effect of MP in ameliorating PD symptoms.
