目前,免疫系统已成为许多药物成瘾研究的靶器官,因为该系统的改变能导致免疫降低。由于吗啡是这些成瘾药物之一,又用于治疗。为此,本文研究了吗啡在体外初次与人淋巴细胞接触时,该药对人淋巴细胞有丝分裂反应的影响。材料和方法:健康成年志愿者17名,每人抽血10ml,肝素抗凝。按Boyum法用Ficoll-Hypaque密度梯度分离淋巴细胞, At present, the immune system has become the target organ of many drug addiction research, because the change of the system can lead to the decrease of immunity. Since morphine is one of these addictive drugs, it is also used for treatment. To this end, this article studies the morphine in human first contact with human lymphocytes, the drug on human lymphocyte mitosis. Materials and Methods: 17 healthy adult volunteers, each blood draw 10ml, heparin anticoagulation. Lymphocytes were isolated by Ficoll-Hypaque density gradient by Boyum method,
