尖锐湿疣中人乳头瘤病毒DNA检测及存在情况初探

DETECTION AND ANALYSIS OF HUMAN PAPILLOMAVIRUS DNA IN CONDYLOMA ACUMINATUM

尖锐湿疣的发病与人乳头瘤病毒密切相关。本文用打点杂交法检测了28例尖锐湿疣病理标本,其中14例与HPV-11探针杂交阳性,阳性率50%(14/28)。对其中杂交信号较强的9例进一步分别用BamI Ⅱ、PstI酶解,Southem转印后与HPV-11探针杂交,对病毒DNA存在形式进行分析,结果证实HPV-11在尖锐湿疣细胞中主要以游离形式存在。

Condyloma acuminatum is closely associated with human papillomavirus (HPV). In this study the method of slotting hybridization was used to detect the Specimens of 28 cases of condyloma acuminatum. Fourteen out of the 28 samples were positive for HPV 11 probe, the positive rate was 50% (14/28). Nine out of the 14 positive samples were digested with Bamll Ⅰ and Pst Ⅰ respectively to study the present state of DNA after using Southern blotting hybridization. It was shown that HPV 11 DNA were mainly present in a simple monometric episomal state in the condyloma acuminatum cells.
