This experiment was designed to determine the effective dose of zingerone against the sublethal dose of lead acetate that induced brain dysfunctions in rats through using different successive doses of zingerone on some parameters related to oxidative stress for 28 days. Thirty-six adult male rats were randomly selected and divided equally into six experimental groups and treated for 28 days as follows: Control group: administered (orally) sterile distilled water. G1 group: administered (orally) (1/280 from LD50) of lead acetate and treated with 25mg/kg for 4 weeks, the rats were then dissected. G2 group: administered (orally) (1/280 from LD50) of lead acetate and treated with 50mg/kg for 4 weeks, the rats were then dissected. G3 group: administered (orally) (1/280 from LD50) of lead acetate and treated with 100mg/kg for 4 weeks, the rats were then dissected. G4 group: administered (orally) (1/280 from LD50) of lead acetate and treated with 150mg/kg for 4 weeks, the rats were then dissected. G5 group: administered (orally) (1/280 from LD50) of lead acetate and treated with 200mg/kg for 4 weeks, the rats were then dissected. Blood samples were collected, by heart punched under anesthesia, at the end of the experiment for measuring the serum malondialdehyde, neuroglobulin, and dopamine concentrations. The result showed a significant (P<0.05) positive correlation between successive doses of zingerone and dopamine and neuroglobulin concentrations, while a significant (P<0.05) negative correlation between successive doses of zingerone and the concentration of malondialdehyde in all animals that are treated with lead acetate compared to the control group. Concluded from this research show that the zingerone has potent antioxidants and neuroprotective effects at the dose 125 mg/kg BW may result in a significant improvement of the neurotransmitter levels and decrease in the production of oxidative stress to the brain tissue.
