1997年底 ,日本学者报道了一种与肝功能异常有关的ＤＮＡ病毒 ,并命名为ＴＴ病毒 (ＴＴＶ) [1] 。为了解我国病因不明肝炎患者中ＴＴＶ感染状况 ,我们采用聚合酶链反应(ＰＣＲ)和原位杂交的方法检测了血清及肝组织中ＴＴＶ表达情况 ,现报道如下。一、研究对象及标本来源患者年
At the end of 1997, a Japanese scholar reported a DNA virus associated with liver dysfunction and named it as the TTV (TTV) [1]. In order to understand the status of TTV infection in patients with hepatitis of unknown etiology in our country, we detected the expression of TTV in serum and liver tissue by polymerase chain reaction (PCR) and in situ hybridization and are reported as follows. First, the research object and specimen source patient years
