加味四逆散对慢性束缚应激大鼠海马部分氨基酸含量的影响

目的：观察加味四逆散对慢性束缚应激大鼠海马部分氨基酸含量的影响。 方法： 大鼠随机分为3组：正常对照组、模型组、加味四逆散组。采用OPA高效液相色谱分析法检测海马氨基酸含量。 结果： 模型组海马谷氨酸（Glu）、天冬氨酸（Asp）含量明显高于正常对照组（P<0.01），γ-氨基丁酸（GABA）和牛磺氨酸（Tau）含量明显低于正常对照组（P<0.01或P<0.05）；加味四逆散组Glu、Asp明显低于模型组（P<0.05），GABA和Tau含量变化不明显。 结论： 加味四逆散能调节慢性束缚应激反应海马部分氨基酸水平，防止兴奋性氨基酸的神经毒性作用。

Effect of Jiawei sinisan on the levels of some amino acids in hippocampus of rats with chronic stress

AIM: To observe the effect of Jiawei sinisan (JWSNS) on some amino acids in hippocampus of rats with chronic stress. METHODS: Wistar rats were randomly divided into 3 groups: control, model and JWSNS group. OPA (HPLC) was adopted to detect the contents of amino acids in hippocampus. RESULTS: The contents of Glu and Asp in hippocampus of model group increased significantly ( P < 0.01), while the contents of GABA and Tau decreased significantly ( P < 0.01 or P < 0.05). In JWSNS group, the contents of Glu and Asp decreased significantly, although GABA and Tau was no significant difference compared with the chronic stress group. CONCLUSION: JWSNS regulates the levels of amino acids in hippocampus during chronic stress, which prevents the neuro - toxicity of excitatory amino acids.
