In the present study, twenty four adult male albino rats were classified into four groups. The control group received normal diet and water; the second group was treated daily with oral dose of Ginkgo biloba (200 mg/kg body weight [b.wt]) for 3 mo; the third group was treated daily with oral dose of aluminum chloride (10 mg/kg b.wt) for 3 mo; and the fourth group was treated with both Ginkgo biloba and aluminum chloride (200 and 10 mg/kg b.wt, respectively) using a stomach tube for 3 mo. The results showed that administration of AlCl3 to rats induced significant increase (P < 0.05) in thiobarbituric acid reactive substance and decrease (P < 0.05) in glutathione, catalase, and superoxide dismutase in brain and testis homogenates. The data also showed significant decrease (P < 0.05) in noradrenaline, dopamine, and serotonin (5-HT) levels in brain tissue. The rats administered AlCl3 showed significant decrease (P < 0.05) in serum zinc (Zn) and copper (Cu), significant increase (P < 0.05) in serum iron (Fe), and non-significant decrease in magnesium (Mg). Furthermore, significant increase (P < 0.05) in serum alkaline phosphatase and acid phosphatase and significant decrease (P < 0.05) in testosterone were recorded. The histologic examination showed some degenerative changes in both brain and testis tissues while significant improvement in biochemical and histologic changes were observed in the aluminum chloride plus Ginkgo biloba group. It could be concluded that the protective effect of Ginkgo biloba may be attributed to its antioxidant properties.
