纹状体中亮—脑啡肽在针剌调节免疫功能中的作用

Zusanli points of rat were used to study the effect of acupuncture on the synthesis and release of endogenous leu-enkephalin (LEK) in modulating immune function as assayed by T lymphocyte proliferative response, i.e. the lymphocyte transformation test (LTT). The results are as follows: (1) LEK level in striatum was increased as LTT was enhanced by puncture. The latter effect could be inhibited by microinjection of naloxone into striatum. (2) Injection of LEK into striatum caused a significant enhancement of LTT, an effect being more powerful than did by electropuncture. (3) Following injection of LEK antiserum into striatum, electropuncture enhanced LTT was inhibited. The above results demonstrate that the LEK plays an important role in modulating cellular immune function during electropuncture, through its action in striatum either as a neurotransmitter or as a neuromodulator.     

注射热损伤大鼠纹状mRNA的爪蟾卵母细胞对多巴胺的反应

将从下沉大鼠和热损伤大鼠的中枢纹状体提取的ｐｏｌｙ（Ａ）＾＋ｍＲＮＡ,注入非洲爪蟾卵母细胞表达。用电生理方法检测多巴胺诱发的膜电位和电流的变化,分析热损伤对中枢多巴胺受体表达的影响。结果表明,注射大鼠纹状体ｍＲＮＡ后,卵母细胞的静息电位与注射 前没有变化,但多巴胺能诱发膜电流。经验证,此受体电流的主要载流离子是Ｃ１＾－。注射热务大鼠纹状体ｍＲＮＡ的卵母细胞对多巴胺反应的敏感性降低,与正常大鼠组相比
