摘要
目的研究正常人角膜内单疱病毒（ｈｅｒｐｅｓｓｉｍｐｌｅｘｖｉｒｕｓ，ＨＳＶ）基因存留的可能性。方法用聚合酶链反应（ｐｏｌｙｍｅｒａｓｅｃｈａｉｎｒｅａｃｔｉｏｎ，ＰＣＲ）技术对２２例（２２片）正常人角膜、６例（６片）胚胎角膜（阴性对照）及６例单疱病毒性角膜炎（ｈｅｒｐｅｓｓｉｍｐｌｅｘｋｅｒａｔｉｔｉｓ，ＨＳＫ）急性期患者角膜（阳性对照）进行检测。结果２２片正常角膜中２０片存有ＨＳＶＤＮＡ，２片角膜ＨＳＶＤＮＡ阴性，６例胚胎角膜ＰＣＲ为阴性，６例ＨＳＫ急性期患者角膜为阳性。结论正常人角膜中有ＨＳＶＤＮＡ存留。
Objective To determine whether herpes simplex virus (HSV) is present in normal cornea. Methods HSV genome in 22 corneas from donors without the history of herpes simplex keratitis (HSK), 6 positive control corneas from patients with active herpetic keratitis and 6 negative control corneas from embryos was detected by using polymerase chain reaction (PCR). Results HSV DNA was present in 20 of 22 normal corneas, and no viral genome was detected in any of the embryonic corneas. All the corneas from patients with active herpetic keratitis showed positive PCR results. Conclusions The results indicate that the HSV genome is present in some normal corneas, that is concordant with the seropositive rate of HSV in people.
