肌酸對小鼠周圍神經(jīng)損傷修復(fù)的影響及機制研究

肌酸對小鼠周圍神經(jīng)損傷修復(fù)的影響及機制研究摘要：

目的：本研究旨在探究肌酸對小鼠周圍神經(jīng)損傷修復(fù)的影響及其機制。

方法：采用小鼠周圍神經(jīng)損傷模型，將小鼠隨機分為對照組和實驗組，實驗組分為低劑量組、中劑量組和高劑量組。對照組僅進行手術(shù)切口，實驗組在手術(shù)切口基礎(chǔ)上在傷口周圍注射不同劑量的肌酸溶液。觀察小鼠行動能力、神經(jīng)電信號傳遞、神經(jīng)元再生情況等。

結(jié)果：肌酸組小鼠的跛行現(xiàn)象逐漸改善，行動能力逐漸恢復(fù)。高劑量組小鼠神經(jīng)電信號傳遞能力明顯高于低劑量組和中劑量組，同時高劑量組小鼠神經(jīng)元再生情況明顯優(yōu)于其他兩組。

結(jié)論：肌酸能夠促進小鼠周圍神經(jīng)損傷的修復(fù)，提高其神經(jīng)電信號傳遞能力和神經(jīng)元再生能力。這些作用可能與肌酸能夠促進ATP的合成，從而提高神經(jīng)元新陳代謝有關(guān)。

關(guān)鍵詞：肌酸，周圍神經(jīng)損傷，神經(jīng)元再生，神經(jīng)電信號傳遞，ATP合成。
