阿片多肽参与流行性乙型脑炎发病机制的临床研究

Clinical study on opioid polypeptides involved in epidemic encephalitis-B pathogenesis.

目的 研究内源性阿片多肽参与流行性乙型脑炎的发病机制与病理意义。方法 采用改良放射免疫法分别测定乙脑患者极期及恢复期血及脑脊液中亮氨酸 -脑啡肽、β -内啡肽、强啡肽值进行统计学分析。并分别设立阿片多肽特异对抗剂—纳络酮治疗组与对照组 ,进行疗效比较。结果 乙脑患者极期时血及脑脊液中阿片多肽显著升高 ,进入恢复期下降至正常水平。纳络酮治疗组优于对照组 ,各症状疗效统计学分析有显著差异。结论 乙脑患者极期时血及脑脊液中显著升高的阿片多肽与乙脑发病有关 ,并证实纳络酮治疗有效 。

Objectives In order to study the endogenous opioid polypeptides involved in pathogenesis of epidemic encephalitis-B and the clinical therapeutic efficacy.Methods ①Leucine-enkephalin,β-endophin and Dynorphin levels in plasma and and CSF of patients with epidemic encephalitis-B during critical stage and convalescent stage were measured by radio-immunoassay.②Naloxone therapeutic efficacy in patients with epidemic encephalitis-B were investigated.Results Opioid polypeptides levels In plasma and CSF were significantly higher in critical stage and dropped to normal levels in convalescent stage.③We demonstrated that endogenous opioid polypeptides special antagnoist agent-Naloxone was a very important therapy agent for epidemic encephalitis-B patients.Therapy group efficacy was significantly better than control group.Conclusions These results demonstrate that endogenous opioid polypeptides involves in the physiopathologic changes of epidemic encephalitis-B.
