100％，量效关系有高度显著性(P.01)，EC50=2.97mmol/L；经茶碱(20mmol/L)处理的细胞，其DNA凝胶电泳带没有&梯子&状分布；与不同浓度茶碱（5-80 mmol/L）在CO2培养箱孵育15 min，小脑颗粒神经元内cAMP均升高，且是剂量依赖性的。

E. , ACTH antagonizes the analgesia mediated byμand δ opioid receptors, but notκreceptor;(2) The antagonizing effect of ACTH on opioid analgesia is proposed to be mediated by ACTH receptors, although the latter has not been characterized;(3) A contradictory interaction on intracellular cAMP content may constitute one of the postreceptor mechanisms underlying ACTH antagonism of opioid analgesia;(4) Another proposed mechanism of the anti-opioid effect of ACTH is that ACTH can modulate opioid-induced suppression of calcium influx;(5) ACTH has been shown to induce Fos protein expression in selected areas of the rat brain including the nuclei involved in pain regulation as well as the ependyma of the third ventricle and the aqueduct.

根据以上实验结果，本论文首次提出以下论点：（1）ACTH在脊髓水平对抗阿片镇痛具有受体选择性，即ACTH可对抗μ受体和δ受体介导的镇痛，不对抗κ受体所介导的镇痛；（2）由于ACTH与阿片μ受体的肽类配体的结合位点仅有很低的亲和力，与μ受体的非肽类配体的结合位点以及δ受体无亲和力，推测ACTH是通过中枢内的ACTH受体介导发挥抗阿片效应的；（3）ACTH抗阿片作用的受体后作用机制之一是在cAMP信使通路水平与阿片发生相互作用；（4）ACTH抗阿片作用的另一受体后机制是在〓水平影响阿片的效应；（5）通过Fos蛋白的诱导揭示：ACTH可以作用于脑内多个核团，其中包括许多与痛觉调制有关的核团，推测ACTH可能通过激活这些核团的神经元而发挥其中枢效应。

Result:There were IR and DCI existed in the patients which appeared as the elevation of the absolute value of ISI,〔Ca2+〕t and CE-cAMP and decrease of the activity of the ion pump in the erythrocytic membrane. 15 of the 31 patients had hyperinsulinemia.
