【摘要】 目的：研究吉林市１０～１１岁小学生链球菌的感染状况方法：用ＡＤＮａｓｅ Ｂ微量法对吉林市１０～１１岁城乡小学生做抗链菌脱氧核糖核酸酶Ｂ（ＡＤＮａｓｅ Ｂ）滴度测定。结果：城市小学生ＤＮＡ酶Ｂ抗体平均几何滴度为５６ｕ／ｍｌ、农村为５９ｕ／ｍｌ。城市与农村的测定结果无明显差异。结论：由于此种抗体的滴度可以标准化，因此推荐ＡＤＮａｓｅ Ｂ作为除ＡＳＯ外应测定的第二抗体。更多还原

【Abstract】 Objeetive: To study the state of streptococcal infection for students of 10-11 years old in both town and country. Methods: ADNase B Mieromethods. Results: Average geometrie titration of ADNase B for urban students is 56u/ml. for suburban students is 59 u/ml. there is no evident difference between town and country. Conclusion: Because of the importance of this antibody and standardization to its titration detrmination, we recommend, besides ASO, ADNase B be de-termined as the second antibody when the doctor suspects the patients of strcptococcal infection.更多还原
