The normal levels of ribonuclease activity in the serum of children of both sexes of various ages. The children into four age groups: thee 1st grous--from 1 to 7 days of age, the 2nd--from 1 to 12 months, 3rd--from 1 to 3 years, 4th--from 7 to 14 years of age. The ribonuclease activity amounted, in the various age groups, respectively tto: 1st group--0.27+0.07 ug/ml of serum, 2nd--0.21+0.06 ug/ml, 3rd--0.15+0.04 ug/ml, 4th--0.14+0.04 ug/ml.
不同年龄段男女儿童血清中核糖核酸酶活性的正常水平。将儿童分为四个年龄组:第一组——1至7日龄,第二组——1至12个月,第三组——1至3岁,第四组——7至14岁。各年龄组的核糖核酸酶活性分别为:第一组——0.27 + 0.07微克/毫升血清,第二组——0.21 + 0.06微克/毫升,第三组——0.15 + 0.04微克/毫升,第四组——0.14 + 0.04微克/毫升。
