TTV是一种单股DNA病毒,与肝功能异常有密切关系,其致病机理不甚明了,1997年底日本学者发现该病毒并命名为TTV。近来,国内学者对该病毒研究也较多。我们将1996年4月～1999年6月间收集的非甲～非庚(NA～NG)型肝炎患者的血清标本87例,进行TTV-DNA检测,现报道如下。 1 材料与方法 1.1 研究对象 87份血液标本均采自我院门诊及住院的87位患者,男52例,女35例,年龄18～57岁,平均37.6岁,分 TTV is a single-stranded DNA virus, which is closely related to abnormal liver function. Its pathogenic mechanism is not clear. At the end of 1997, Japanese scholars found the virus named TTV. Recently, domestic scholars have also studied the virus more. We collected 87 cases of non-A to non-Hepatitis A (N-G) hepatitis patients collected from April 1996 to June 1999 for TTV-DNA detection and are reported as follows. 1 Materials and Methods 1.1 Subjects 87 blood samples were taken from our hospital outpatient and hospitalized 87 patients, 52 males and 35 females, aged 18 to 57 years, with an average of 37.6 years old,
