“丙球”(丙种球蛋白)是从健康产妇胎盘血或健康人血中提取的一种含多种“抗体”的生物制剂。其作用机理为被动免疫,即把他人体内的免疫物质(抗体)拿来,为己所用。由于大多数成人或产妇都曾与甲肝、麻疹、风疹、水痘和腮腺炎等“较量过(感染过或隐性感染过),其血液内存在这些疾病相应的“抗体”,故对上述几种疾病有较明显的预防作用。但对其他常见的多种疾病,如感冒、哮喘、慢性支气管炎、肺结核、乙肝和癌症等,几乎无任何防治效果。 “Bulb” (gammaglobulin) is a biological preparation that contains multiple “antibodies” extracted from healthy maternal placental blood or healthy human blood. Its mechanism of action is passive immunization, that is, other people’s body to use immune substances (antibodies), for their own use. As most adults or mothers have had “antibodies” corresponding to these diseases in the bloodstream, such as hepatitis A, measles, rubella, chickenpox and mumps, The disease has a more obvious preventive effect, but it has almost no preventative effect on other common diseases such as colds, asthma, chronic bronchitis, tuberculosis, hepatitis B and cancer.
