对232名1995年1~12月份小生儿童接种卡介苗1年后,进行结素试验,观察其硬结反应与卡疤反应情况。卡疤率为90.95%(211/232),结素阳性率为56.03%(130/232),两者比较,P＜0.01。对卡疤率和结素反应阳性率失同步反应的原因进行了分析。
One year after the BCG vaccination of 232 niche children from January to December in 1995, the tuberculin test was carried out to observe the induration reaction and the scar reaction. The rate of scarring was 90.95% (211/232), the positive rate of knot was 56.03% (130/232), P <0.01. The reasons for the out-of-synchronic reaction between the rate of kelvosis and the positive rate of tuberculin reaction were analyzed.
