Modulation the Neuro-toxicity Induced by Aluminum Chloride in Rats Using Beetroots and Broccli Extracts

Backgound: The generation of oxidative stress can be referred to Aluminium toxic effect in animals and humans. This study aimed to evaluate the role of broccoli (Br) and beetroot (Be) extarcts as antioxidant that prevents oxidative stress that associated with aluminum toxicity. Materials and Methods: Fifty Wister female rats were grouped into five groups (each 10 rats): Group 1: control group, administered drinking water only. Group 2: (Neurogenerative) which were induced by oral administration of aluminum chloride (20 mg/kg b.w) daily for one month. Group 3: Rats given aluminum chloride were treated with Rivastigmine (Ri) (1 mg/kg b.w) as a reference drug daily for five weeks. Group 4: Rats given aluminum chloride were treated with beet root extract (50 mg/kg b.w) daily for six weeks. Group 5. Rats given aluminum chloride were treated with broccoli extract (50 mg/kg b.w) daily for five weeks. Results: (AlCl3) group showed a significant increase in Ach level (P<0.05) and a non-significant change in DOP and NE levels compared to control. (AlCl3+Be) was non-significant (P˂0.05) change in Ach, DOP and NE levels compared to (AlCl3) group and showed a significant (P<0.05) increase in Ach level compared to control. (AlCl3+Br) showed a significant (P<0.05) increase in NE level and non-significant (P˂0.05) change in Ach and DOP levels compared to (AlCl3) group. (AlCl3+Ri) showed a significant (P<0.05) increase in Ach, DOP and NE levels compared to (AlCl3) group. Also, showed a significant (P<0.05) increase in Ach and NE compared to control. Conclusion: Neuroprotective role of broccoli in the present study which may result from its antioxidant properties due to its bioactive content such as glucosinolate, isothiocyanate, Sulforaphane, and flavonoids. Therefore, Broccoli can have a favorable effect on neurotoxicity due to their antioxidant and anti-inflammatory properties.
