自Krugman等发表关于病毒性肝炎的MS—1和MS—2株抗原性的研究结果以来,近十年间的进展已迅速改变了有关医生们的处境。今天的内科医生可用被动、自动或被动-自动免疫的方法,来预防三种类型的病毒性肝炎中的两种:甲型肝炎(HA)和乙型肝炎(HB)。对第三种类型的病毒性肝炎,即非甲非乙型肝炎的免疫办法,在这种类型肝炎的病原体能得到鉴定之前,尚无可能。用正常的混合免疫血清球蛋白(NIG)一次注射对甲型肝炎进行被动免疫,可使病人得到8至12周的保护,而且如果感染已经发生,在潜伏期及早(2～4周内)给予NIG,仍能提供部分保护。与此相反,对乙型肝炎
Since Krugman et al. Published research on the antigenicity of MS-1 and MS-2 strains of viral hepatitis, the progress of the past decade has rapidly changed the situation of the doctors concerned. Today’s physicians can use passive, automatic or passive-autoimmune methods to prevent two of the three types of viral hepatitis: Hepatitis A (HA) and Hepatitis B (HB). The immunization against the third type of viral hepatitis, non-A, non-B, is not possible until the pathogens of this type of hepatitis have been identified. Passive immunization of Hepatitis A with a single injection of normal mixed immunoglobulin (NIG) gives the patient 8 to 12 weeks of protection and, if the infection has occurred, is administered to the NIG early and late (within 2 to 4 weeks) , Still provide some protection. In contrast, for hepatitis B
