Abstract： 目的 探讨谷氨酰胺复方制剂对晕船后大鼠脑体疲劳的影响.方法 取112只SD雄性大鼠,随机分为正常对照组(N)、生理盐水组(S)、谷氨酰胺组(G)、谷氨酰胺+维生素组(GV)、谷氨酰胺+维生素+支链氨基酸组(GVB),谷氨酰胺+维生素+酪氨酸组(GVT),谷氨酰胺+维生索+支链氨基酸+酪氨酸组(GVBT),每组又随机分为A组和B组,每组8只.连续灌胃21 d,模拟晕船刺激3 d,取每组中的A组,测定其游泳时间;B组测定其学习记忆能力和生化指标.结果 与S组相比,N组(P＜0.05)、GVB组和GVBT组(P＜0.01)的游泳时间显著延长;N组和GVT组的学习记忆能力显著增强(P＜0.05);N组、GV组、GVB组和GVBT组的血清尿素氮的含量显著降低(P＜0.05);GV组,GVB组,GVBT组(P＜0.05)和GVT组(P＜0.01)的脑乳酸的含量显著下降;N组、G组、GV组和GVB组的血乳酸含量显著降低(P＜0.05);G组、CV组、GVB组和GVT组的肌糖原的含量显著升高(P＜0.05和P＜0.01);N组(P＜0.05),G组、GV组、GVB组、GVT组和GVBT组(P＜0.01)的肝糖原含量显著升高.结论 谷氨酰胺复方制剂具有提高晕船大鼠脑体功能的作用,其作用机制可能与增加肝糖原储备,改善脑的有氧代谢,以及提高骨骼细胞对能量物质的利用有关.
