本文研究各种浓度（１０－８ｍｏｌ／Ｌ～１０－５ｍｏｌ／Ｌ）去甲肾上腺素（ＮＥ）对Ｔ淋巴细胞增殖的影响，并初步探讨ＮＥ影响Ｔ细胞功能的作用时间。实验结果说明：１０－８～１０－５ｍｏｌ／Ｌ范围内各种浓度的ＮＥ均可抑制Ｔ细胞对刀豆素Ａ（ＣｏｎＡ）的增殖反应；淋巴细胞先与ＮＥ作用１ｈ后再接受ＣｏｎＡ刺激，其增殖反应同样可被ＮＥ所抑制，但淋巴细胞接受ＣｏｎＡ刺激６ｈ后再与ＮＥ作用，其增殖反应就不再被ＮＥ所抑制，本实验结果提示，ＮＥ在较广的浓度范围内均可抑制细胞免疫功能；ＮＥ的这种免疫抑制作用可能发生于Ｔ细胞激活前或激活后初期。
In this paper, we studied the effect of norepinephrine (NE) in various concentration (10-8mol / L ~ 10-5mol / L) on the proliferation of T lymphocytes and explored the effect of NE on T cell function. The results showed that all concentrations of NE in the concentration range of 10-8 ~ 10-5mol / L could inhibit the proliferation of T cells against ConA. Lymphocytes were stimulated with ConA for 1h with NE, The proliferative response was also inhibited by NE, but lymphocytes were inhibited by NE after stimulated by ConA for 6h, and the proliferative response was no longer inhibited by NE. Our results suggest that NE could be inhibited in a wide range of concentrations Cellular immune function; NE of this immunosuppressive effect may occur before T cell activation or early after activation.
