丙种球蛋白是以硫酸铵盐析法或低温乙醇法(亦有用利凡诺法)等手段从胎盘血或人血浆中分离而得的一种含有丰富免疫球蛋白(以下简称Ig)的制剂。根据其生物化学和抗原结构的差别Ig可分为五类(即IgG、IgA、IgM、IgD、IgE)。IgG占血清Ig总量的80左右(其余约15％为IgA、5％左右为IgM、以及很少量的IgD、IgE),为丙种球蛋白主要成份。IgG类具有抗菌、抗病毒、抗毒素等多种抗体作用。据有人测定证实:白喉抗毒素、破伤风抗毒素、百日咳抗体、麻疹抗体、腮腺炎抗体、脊髓灰质炎抗体、流感抗体、传染性肝炎抗体、链球菌抗毒素、以及伤寒付伤寒杆菌抗体等主要存在于IgG内。因此,从理论上讲如使用得法,对有关疾病都能发挥一定的防治作用。但事实并非如
Gamma globulin is a preparation containing abundant immunoglobulin (hereinafter referred to as Ig) isolated from placental blood or human plasma by ammonium sulfate salting out method or low temperature ethanol method (also useful for levonodine method). Ig can be divided into five categories (ie, IgG, IgA, IgM, IgD, IgE) based on their biochemical and antigen-structure differences. IgG accounted for the total serum Ig about 80 (the remaining about 15% of IgA, about 5% of IgM, and a very small amount of IgD, IgE), the main component of gamma globulin. IgG class with anti-bacterial, anti-virus, anti-toxin and other antibodies. It was confirmed by some tests that diphtheria anti-toxin, tetanus antitoxin, pertussis antibody, measles antibody, mumps antibody, polio antibody, influenza antibody, infectious hepatitis antibody, streptococcal antitoxin, and antibody against Salmonella typhi are mainly present in IgG Inside. Therefore, in theory, if used properly, all the diseases can play a preventive and therapeutic role. But it is not true
