我军每年从各地征集的新兵,过着高度集中的军营生活,其群体流感抗体免疫水平的高低,对预防和预测流感流行有重要意义。为此,本文对1992年北京市新入伍战士进行血清流感抗体水平检测和分析。对象与方法一、对象 1991年12月16日～20日在北京南郊、北郊和长辛店三个部队新入伍820名18～20岁战士,空腹取血1～2ml,分离血清,-30℃保存,待测。兵源分别来源干安徽省凤阳;湖北省宜昌;四川省重庆;山西省太原;河北省冀县;天津市武清以及山东省曲阜。二、方法按文献流感抗体微量半加敏血凝抑制方法进行,抗体效价<1∶10为阴性,≥1∶10为阳性。计算GMT值(几何平均滴度),不包括抗体阴性者。三、主要试剂
Every year, recruits recruited by our army from all over the country live highly concentrated barracks and the level of influenza antibody immunity among their groups is of great significance in preventing and predicting the influenza pandemic. Therefore, this paper tests and analyzes the antibody level of serum flu in newly admitted soldiers in 1992 in Beijing. Subjects and Methods I. Object In December 16, 1991 to December 20 in the southern suburbs of Beijing, the northern suburb and Chang Xindian three new recruits 820 soldiers aged 18 to 20, 1 to 2 ml fasting blood, serum was separated, -30 ℃ save, test. Soldiers were sourced from Fengyang, Anhui Province; Yichang, Hubei Province; Chongqing, Sichuan Province; Taiyuan, Shanxi Province; Ji County, Hebei Province; Wuqing, Tianjin Municipality and Qufu, Shandong Province. Second, the method according to the literature influenza antibody semi-sensitized hemagglutination inhibition method, the antibody titer <1:10 negative, ≥ 1:10 positive. Calculate the GMT value (geometric mean titer) excluding those with negative antibodies. Third, the main reagent
