在防治疟疾中,免疫是一条重要而有希望的途径。我们从免疫方面进行摸索性试验,希望能从体外培养疟原虫,以制成人工自动免疫用的预防制品。其先决条件是大量获得原虫作为抗原,而体外培养是大量获得原虫的重要方法。本文报告在疫区对5例人恶性疟疾患者治疗前的血液,进行体外培养的结果并加以分析讨论。 In the fight against malaria, immunization is an important and promising avenue. We conducted a groping experiment on immunization and hoped that we could cultivate the parasite in vitro so as to make the preventive products for artificial autoimmune diseases. The precondition is that a large number of protozoa are obtained as antigen, while in vitro cultivation is an important method for obtaining protozoa in large quantities. This paper reports the results of in vitro culture of five patients with malignant malaria before treatment in the endemic areas and analyzes and discusses the results.
