体外基因扩增技术探讨中线恶网的病毒病因

Role of Virus in the Causation of Midline Malignant Reticulosis

采用２８例中线恶性网织细胞增多症（Ｍｉｄｌｉｎｅｍａｌｉｇｎａｎｔｒｅｔｉｃｕｌｏｓｉｓ，ＭＭＲ）病理石蜡切片为样品，应用聚合酶链式反应（Ｐｏｌｙｍｅｒａｓｅｃｈａｉｎｒｅａｃｔｉｏｎ，ＰＣＲ）技术检测到共有１９例（１９／２８，６８％）样品扩增出Ｅｐｓｔｅｉｎ－Ｂａｒｒ病毒（Ｅｐｓｔｅｉｎ－Ｂａｒｒｖｉｒｕｓ，ＥＢＶ）ＤＮＡ，提示ＭＭＲ病变组织中存在较高的ＥＢＶ感染率。

Epstein-Barr virus(EBV)DNA was examined on the paraffin embedded specimens from 28 patients with Midline malignant reticulosis(MMR)by polymerase chain reaction technique. The positive rate of EBV was 68% (19 out of 28 cases).the result indicated that the frequency of EBV infection was pretty high in MMR lesions.
