Abstract

Introduction: The protective effect of Ginkgo biloba (Gb), a natural antioxidant, against toxicity induced by chemical and physical agents has been the subject of studies. Objective: To propose quantitative methods associated with histological techniques to analyze the effectiveness of Gb as a cerebral radioprotector. Method: 35 rats were used, grouped into: group 1: control; group 2: exposed to ionizing radiation (IR); group 3: treated with Gb; group 4: exposed to IR and subsequently treated with Gb; group 5: treated with Gb and subsequently exposed to IR. The recordings obtained by the electrocorticogram were evaluated using the Fourier Transform, Approximate Entropy and Lempel-Ziv Complexity. Finally, the hippocampus was collected and analyzed using histological techniques. Results: The analysis of the experiments shows that IR interferes with cortical electrical activity, increasing the frequency of delta and beta waves and decreasing theta and alpha. While groups 4 and 5 were similar to 1, demonstrating a radioprotective capacity. Regarding histology, apoptosis was identified in group 2 in the CA1 and Dentate Gyrus region of the hippocampus. Conclusion: Based on these data, it is concluded that the protective effect of Gb extract can act as an adjunct therapy to reduce IR-induced toxicity.
