为了解博乐垦区儿童少年血清中抗-HBs免疫水平,指导乙肝疫苗全程接种,预防乙型肝炎发生与流行。我们于1998年5～6月对垦区幼儿园、小学、中学及民族中学2 948名儿童少年进行抗-HBs和HBsAg调查,现将结果报告如下:1 对象与方法1.1 为垦区幼儿园、小学、中学及民族中学儿童少年2 948名,其中男性1 441名,女性1 507名,年龄在3～19岁,进行现场询问乙肝疫苗接种情况,同时静脉采血2ml分离血清待检。1.2 抗-HBs采用EIA,计算OD值=样品测定吸光度A/阴性对照平均吸光度A,判定OD值<2.1为阴性反应,>2.1为阳性,且在2.1～9.9、10～40、>40范围OD值定为弱阳性、阳性和
In order to understand the level of anti-HBs immunity in children and adolescents Bole reclamation area, to guide the full vaccination of hepatitis B vaccine to prevent the occurrence and prevalence of hepatitis B. We investigated 2 948 children and adolescents in kindergartens, primary schools, secondary schools and ethnic secondary schools from May to June 1998 for anti-HBs and HBsAg surveys. The results are reported as follows: 1. Subjects and Methods 1.1 Kindergartens, primary and secondary schools and 2,948 ethnic minority middle school children and adolescents, including 1 441 males and 1 507 females, aged 3 to 19 years old, were asked about hepatitis B vaccination on the spot, while 2 ml venous blood was collected for sequestration. 1.2 Anti-HBs using EIA, calculate the OD value = sample absorbance A / negative control average absorbance A, determine the OD value of <2.1 for the negative reaction,> 2.1 was positive and in the range of 2.1 ~ 9.9,10 ~ 40,> 40 OD Value set as weak positive, positive and
