Background: A stroke is a medical condition in which poor blood flow to the brain may result in death. Death as an outcome of stroke is not always the case as partial disabilities and paralysis may happen as well. The use of animal models in recent years has provided a better understanding of the pathophysiologic mechanisms of stroke. Aim: The present study aims to examine the effect of Ginkgo biloba on induced ischemic stroke in rats. Material and Methods: This study was conducted on 60 adult rats weighing 180 ± 20 gm and of 10-12 weeks in age. Ginkgo biloba, the dietary supplement was given orally in ischemic-stroke-induced rats. Hematological and biochemical serum analysis, as well as histological examination, were done to explore the ameliorative effect of ginkgo extract. Results: ANOVA results showed a statistically significant difference in hemoglobin, hematocrit, platelet count, urea, cholesterol, triglycerides, glucose, FT3 and TSH. Post-hoc analysis showed significant increases in urea, cholesterol, triglycerides, glucose, and TSH, while a decrease in platelet count in the ischemic-strokeinduced rats compared with the controls. On the other hand, the group that received G. biloba showed significant decreases in urea, glucose, FT3 and TSH, while the platelet counts significantly increased compared with the ischemicstroke-induced rats. In comparison between the control group with the group that was given G. biloba, a significant increase in triglycerides was noticed. Histology examination demonstrated several alterations in brain, heart and thyroird in ischemic-stroke-induced rats that have been recovered after G. biloba treatment. However, G. biloba induced negative alterations in the thyroid. Conclusion: The results obtained in this study demonstrated that G. biloba-treated group showed better biomarkers. However, G. biloba had unwanted effects on triglycerides and thyroid as observed. Further study on the effect of G. biloba on the thyroid gland is required.
