西宁地区正常儿童四唑氮兰(NBT)实验值微量法的测定及分析

THE WHITE CELL OXIDATION OF NBT IN NORMAL CHILDREN AT XINING

微量法测定白细胞氢化硝基四唑氮兰实验（NBT）具有快速、简便、准确等优．点，是协助临床区分病毒与细菌感染较特异的一种实验方法。为了使此法在我省开展，我们于1994年7月至1995年6月对海拔2260米的西宁市247名正常儿童及167名健康孕妇进行了微量法NBT实验值的测定，结果在正常）L童是4．96士3．63（％）健康孕妇是4．53士2．49（％），与国内报导3—10％平均8．5％及国外报导＜10％是一致的。表明全血法NBT实验正常值也适用于海拔2260米西宁地区微量法NBT的测定。经统计学处理，说明微量法NBT阳性率在不满4周岁至不满7周岁儿童各年龄组及性别间不存在显著差异性。在健康孕妇NBT阳性率亦不存在不同妊娠月份之间的差异。故本实验不仅适用于儿童，同样适用于孕妇感染的判断。

The white cell oxidat ion of NBT was measured by microassay method, which has rapid、simple、accurate advantages etc. and was helpful to differentiate bacterial and virus infection in clinical. In order to try out this method in our province, we investigated 247 examples of health children and 167cases of health pregnant women in Xining where altitude was 2260 meters above sea level from July 1994 to June 1995. The values were 4. 96± 3. 63% in children and 4. 53± 2. 49 % in pregnant women respectively, which similar to the 3-10 %, means 8. 5 % of home and <10 % abroad reported. All data after statistically analyzed showed that no statistical significance of the differences in aged group and sexual group of children from 4to 7 years old, also no remarkable significance of the differences between gestational months in pregnant women. The results suggested that this method also can be practiced in Xining area where altitude was 2260 meters above sea level to determine bacterial and virus infection in children and pregnant women.
