聚合酶链反应在确定男性急性淋菌性尿道炎治愈标准中的意义

对２１例男性急性淋菌性尿道炎（ＡＧＵ）患者治疗前后的涂片查脓细胞，涂片染色查淋菌和淋菌培养与ＰＣＲ查淋菌的结果进行比较。治疗前２ｌ例患者全部检查为阳性；停药时１４例ＰＣＲ为阳性，停药ｌ个月时４例ＰＣＲ阳性，停药３个月时１例ＰＣＲ阳性。其余各项检查停药以后均为阴性。在一段时间内，已临床治愈的部分ＡＧＵ患者的ＰＣＲ仍呈阳性，提示ＰＣＲ作为ＡＧＵ治愈标准有较大的局限性。

PCR technique in the study of acute N.gonorrhoeae urethritis

Identification of N. gonorrhoeae by PCR technique was studied together with the conventional procedures(smear for pus cells,stained smear and cultrue for N.gonorrhoeae)both before and after treatment in 21 cases of gonorrhoeae urethritis.PCR and the conventional procedures were all positive in the 21 patients before treatment.After a complete course of treatment,all the conventional procedures turned negative while PCR remained positive in 14 cases,4 beingpositive one month after and 1 three months after.Attention is called to the fact that PCR could not be used to assess the effect of the treatment.
