摘要
应用生物素标记HBV DNA(乙肝病毒脱氧核糖核酸)作探针,对129例肝病患者肝组织作原位杂交研究。HBV DNA在慢性活动性肝炎中检出率最高(80.7%),显著高于肝硬化、慢性小叶性肝炎、急性肝炎及原发性肝癌组。具有乙肝复制指标阳性患者的肝细胞内HBV DNA检出率(82.0%)明显高于非复制组(63.0%),P<0.05。本研究观察到;HBB DNA阳性肝细胞与肝细胞坏死灶关系密切,多位于肝细胞坏死灶中间或(和)周边,其中以局灶型分布的HBVDNA阳性肝细胞与肝细胞坏死灶关系密切。提示HBV复制与肝细胞坏死有关。
A biotin-labelled DNA specific for hepatitis B virus (HBV) nucleo-tide sequences was hybridized in situ to liver tissue of 129 cases with liver diseases.It was found that chronic active hepatitis (CAH) group had a significant higher prevalence (80.7%),as compared with cirrhosis,chronic lobular hepatitis (CLH),acute hepatitis and hepatocellular carcinoma (HCC) groups.HBV DNA in HBeAg positive or intrahepatic HBcAg positive patients (82.0%) was more easily detected than the single HBsAg positive and anti-HBc cases (63.0%,P<0.05).The interesting findings that expressing HBV DNA hepatocytes,particularly as focal distribution were closedly related to hepatic necrotic sites,suggest that HBV replication may occur in conjunction with hepatic necrosis.
