摘译: 1978—1981年,在意大利不同地区收集了1314份携带乙型肝炎表面抗原(HSAg)和687份乙型肝炎病人的血清,对感染δ因子与乙型肝炎病毒的关系作了流行病学评价。研究表明,δ抗原和抗δ抗原的抗体系统的出现,与乙型肝炎病毒有联系,由于感染一种认为是核糖核酸染色体的缺损因子(PNA)(δ因子δ),它需要乙型肝炎病毒的协同作用,才能合成δ因子。δ抗原通常在慢性δ病病人的肝脏发现,但δ抗原很少在血清中存在,仅在感染早期可见。这次调查的每个地区中心,连继6个月至3年,对肝病者大部分经肝活组织检
In 1978-1981, 1314 sera from patients with hepatitis B surface antigen (HSAg) and 687 hepatitis B patients were collected in different parts of Italy and epidemiology of the relationship between the δ factor and the hepatitis B virus Evaluation. Studies have shown that the appearance of antibody systems for the delta and anti-delta antigens in association with the hepatitis B virus requires the hepatitis B virus (HBV) virus due to infection with a defective factor (PNA) (delta factor delta) that is believed to be a ribonucleic acid chromosome Synergy, in order to synthesize δ factor. The delta antigen is commonly found in the liver of patients with chronic delta disease, but the delta antigen is rarely present in the serum and is only visible early in the infection. Each district center of this survey, followed by 6 months to 3 years, most of the patients with liver disease by liver biopsy
