Treatment of guinea pigs with cyclophosphamide before immunization with killed tularemia vaccine in Freund incomplete adjuvant produced a prolongation and intensification of delayed-type hypersensitivity and in vitro lymphocyte transformation reactions to tularemia antigen. Such reactions resemble those ordinarily associated with the administration of live tularemia vaccine, killed vaccine in Freund complete adjuvant, or recovery from natural infection. The immunopotentiation lasted longer than that seen previously in other antigenic systems with this drug and was dependent on the dose of vaccine used. More intense delayed skin reactivity could be transferred into normal controls by cells from immunized donors pretreated with cyclophosphamide than by cells from immunized donors that were not pretreated.
在用弗氏不完全佐剂中的灭活土拉菌疫苗免疫豚鼠之前,用环磷酰胺对其进行处理,可使迟发型超敏反应以及对土拉菌抗原的体外淋巴细胞转化反应延长并增强。此类反应类似于通常与接种活土拉菌疫苗、弗氏完全佐剂中的灭活疫苗或从自然感染中恢复相关的反应。这种免疫增强作用持续的时间比之前在其他抗原系统中使用该药物时观察到的更长,并且取决于所用疫苗的剂量。与未用环磷酰胺预处理的免疫供体的细胞相比,用环磷酰胺预处理的免疫供体的细胞能将更强的迟发性皮肤反应性转移到正常对照中。
