为探讨高血压病（EH）患者细胞免疫功能状况。白细胞介素2（IL-2）对其调节作用及降压效应，运用桥联酶标及重氯化反应等方法，检测100名EH病人治疗前后血浆T淋巴细胞亚群数量、IL-2浓度和一氧化氮（NO）含量。结果表明：EH病人CD、CD数量及IL－2活性低于对照组（P＜0.01），尤以CD为著，IL－2治疗后明显恢复。EH病人NO含量低于对照组（P＜0．01），IL－2治疗后，NO含量回升井离于对照组（P＜0.01），IL-2明显降低EH病人的血压。此结果提示，EH病人细胞免疫功能不良，IL-2对其有纠正作用，并可能通过刺激NO释放产生降压效应。
To investigate the cellular immune function in hypertensive patients (EH). Interleukin 2 (IL-2) on the regulation and antihypertensive effect, the use of bridged enzyme labeling and heavy-chloride reaction and other methods to detect 100 EH patients before and after treatment of plasma T lymphocyte subsets, IL-2 concentration And nitric oxide (NO) content. The results showed that the number of CD and CD and the activity of IL-2 in patients with EH were lower than those in the control group (P <0.01), especially in CD patients. IL-2 significantly recovered after treatment. The content of NO in EH patients was lower than that in control group (P <0.01). After IL-2 treatment, the content of NO rose up from the control group (P <0.01). IL-2 significantly reduced the blood pressure of EH patients. The results suggest that EH patients with cellular immune dysfunction, IL-2 to correct it, and may be produced by stimulating the release of NO antihypertensive effect.
