目的:用聚合酶链反应(POLYM ERASECHAIN REACTION, P C R)检测生殖器疱疹患者单纯疱疹病毒(HERPESSIM PLEX VIRUS 2, H S V2).方法:对101 例生殖器疱疹和糜烂患者及20 例对照组用 P C R法检测 H S V1、 H S V2.结果: H S V2 检出阳性率占 604％ (61/101), H S V2 和 H S V1 双重感染占4％ (4/101).对照组均为阴性,并且年龄轻者感染阳性率高于年龄长者.结论: P C R 具有操作较易、快速、敏感的特点,为临床对生殖疱疹的诊断和鉴别诊断提供了理想的新方法.“,”Objective: We were to investigate the use of PCR in detecting herpes simplex virus 2 (HSV 2) for patients with genital herpes (GH). Methods: PCR technique was applied to examine HSV 1 and HSV 2 in 101 patients with ulcerative GH and 20 normal subjects. Results: The positive rate was 60.4% (61/101) for HSV 2 and 4% (4/101) for dual infection of HSV 2 as wall as HSV 1. Among the patients the infection rate was higher in the young that in the old. All normal persons tested negative. Conclusion: PCR was an easy quick, sensitive. And new method for clinical and differential diagnosis of GH.
