Summary of article contents:
Introduction
Parkinson's disease (PD) is a progressive neurodegenerative disorder primarily characterized by bradykinesia, resting tremor, rigidity, and postural instability. It is associated with the loss of dopamine neurons in the substantia nigra, leading to significant motor control issues. Current treatments for PD, including levodopa and various dopamine agonists, are often accompanied by side effects that can adversely affect patients' quality of life. The present study evaluates the anti-Parkinson’s activity of Brassica nigra (B. nigra) seeds through various experimental models, focusing on their neuroprotective properties, particularly in combating oxidative stress associated with PD.
Neuroprotective Effects of Brassica nigra
The study demonstrated that the hydro-alcoholic extract of Brassica nigra significantly affects both behavioral and neurochemical responses in chlorpromazine-induced models of Parkinson's disease in male Wistar rats. Chronic administration of the extract (400 mg/kg) led to a notable reduction in cataleptic scores and increased locomotor activity compared to control groups. Furthermore, the administration of B. nigra resulted in improved neurochemical markers, as indicated by elevated levels of reduced glutathione (GSH) and decreased levels of thiobarbituric acid reactive substances (TBARS), suggesting a reduction in oxidative stress.
Antioxidant Activity and Mechanism
The antioxidant activity of Brassica nigra was assessed through in vitro studies, specifically examining its DPPH free radical scavenging activity and metal chelation ability. The extract displayed concentration-dependent inhibition of DPPH radicals, with an IC50 value of 26.54 µg/ml, demonstrating its potential as a strong antioxidant. Additionally, the extract showed significant metal chelation at various concentrations, effectively binding ferrous ions and thereby preventing oxidative reactions that may exacerbate neuronal damage. This activity is attributed to its phytochemical constituents, including gallic acid, which may confer protective effects against neuronal degeneration.
Effects on Neurochemical Parameters
The study also evaluated the neurochemical changes associated with Brassica nigra treatment in the context of oxidative stress. Chronic chlorpromazine administration elevated brain TBARS levels, indicative of increased lipid peroxidation, while levels of GSH were significantly reduced, highlighting the oxidative damage in the model. In contrast, treatment with B. nigra markedly reversed these changes, decreasing brain MDA levels and enhancing GSH concentrations. These results suggest that Brassica nigra can mitigate oxidative damage caused by chlorpromazine, providing further insights into its neuroprotective mechanism.
Conclusion
In conclusion, the findings of this study indicate that Brassica nigra possesses significant anti-Parkinson’s activity, primarily through its antioxidant properties and extension of neurochemical support against oxidative stress. The reduction of catalepsy and improvement of locomotor activity in experimental models illustrate its potential as a therapeutic option for managing Parkinson’s disease symptoms. Given its rich phytochemical profile, particularly the presence of gallic acid, Brassica nigra warrants further investigation as a promising candidate for developing alternative or adjunct treatments for PD and other neurodegenerative disorders.
