Siyatik sinir yaralanması oluşturulan ratlarda Andız (Juniperus sp) kökü ekstraktının ve B12 vitamininin sinir iyileşmesi üzerine etkisinin karşılaştırılması

Abstract

The self-repair capacity of peripheral nerves is limited, and the repair of severely damaged or significantly flawed nerves is challenging. For preclinical investigations on peripheral nerve regeneration, the sciatic nerve injury model is the most often used experimental model. In rats, sciatic nerve injury is the most frequently used model in studies related to peripheral nerve regeneration. Material and Methods: In this study, 32 rats were subjected to sciatic nerve injury, and applications of B12 vitamin and Andız root extract were performed. After the applications, the rats were sacrificed on the 21st day, and samples of the sciatic nerve tissue were taken. The collected samples were examined using histopathological and immunofluorescence methods. Results: The examination revealed that B12 vitamin and Andız root extract, when applied separately to the rats, provided limited and similar benefits histopathologically, while the group that received combined treatment showed more effective positive effects compared to all other groups. Additionally, when assessing S100 and GFAP expression through immunofluorescence, it was observed that individual applications provided similar benefits, while the group that received combined treatment contributed more effectively compared to all other groups. Conclusion: In conclusion, in the rat model of sciatic nerve injury, it was determined that Andız root extract and B12 vitamin, when applied separately, had limited and similar effects compared to the control group in determining the levels of recovery. However, when applied together, they exhibited a synergistic effect, providing a greater contribution to nerve regeneration compared to all other groups.
