为了解流感病毒流行和小儿病毒肺炎之间的相互关系,我们对49例肺炎患儿,在临床诊断的基础上进行血清调查,企图通过断面血清学测定了解疾病的累积状态。调查对象与方法(一)观察对象:1983年11月至1984年2月对本院儿科收治婴幼儿肺炎患儿中,于急性期及恢复期采血,分离血清,做血凝抑制试验,双份血清抗体四倍升高者解释为近期流感病毒肺炎。在采集的98份血清中,最小80天,最大4岁,共49例,其中男:28例,女:21例。(二)方法:1.甲_2,甲_3流感病毒两种及抗体,由北京病毒研究所提供。
To understand the relationship between the influenza virus epidemic and pneumonia in children, 49 children with pneumonia were enrolled in a serological survey based on clinical diagnosis in an attempt to understand the cumulative status of the disease by cross-sectional serological testing. Subjects and Methods (I) Subjects: From November 1983 to February 1984, children with infantile pneumonia were admitted to our hospital for pediatric pneumonia. Blood samples were taken during acute phase and convalescent phase, and serum was separated for hemagglutination inhibition test. A fourfold increase in serum antibody is interpreted as recent influenza pneumonia. In 98 sera collected, a minimum of 80 days, a maximum of 4 years old, a total of 49 cases, of which male: 28 cases, female: 21 cases. (B) Methods: 1. A _2, A _3 influenza virus two and antibodies, provided by the Beijing Institute of Virology.
