济南铁路地区近十多年来未发生过白喉流行,人群免疫状况多年来亦未行测定。为了监测流行,考核白喉类毒素的预防接种效果,并为消灭白喉提供科学依据,我们于1979年10月对济南铁路地区所属幼儿园、托儿所、铁五小、铁一中等四个单位448名儿童进行了锡克氏反应调查,借以了解当地人群白喉免疫状况。现将调查结果报告如下。材料与方法一、材料来源: 锡克氏试验及对照液均系北京生物制品研究所出品,批号791,失效期1979年12月15日。二、试验方法与观察标准: (一)试验方法: 每个受试者在两前臂掌侧下1/2与中1/3交界
The prevalence of diphtheria has not occurred in Jinan Railway over the past decade or so and the immune status of the population has not been determined over the years. To monitor the prevalence of diphtheria toxoid vaccination and to provide a scientific basis for the eradication of diphtheria, we conducted 448 children in kindergartens, nurseries, nurseries, mini-irons and middle-irons in the Jinan Railway Region in October 1979 Sackney response survey to understand the local population diphtheria immune status. The survey results are reported below. Materials and methods First, the source of material: Sikhs test and control liquid are produced by the Beijing Institute of Biological Products, batch number 791, expiration date December 15, 1979. Second, the test methods and observation criteria: (a) test method: each subject in the forearm palmar 1/2 and 1/3 of the border
