摘要: 乙型肝炎病毒感染者的精子与去透明带金黄地鼠卵受精制备染色体,并以HBV 全长DNA 作探针对精子染色体进行荧光原位杂交。结果发现慢性迁延型肝炎患者、慢性活动型肝炎患者和HBV 携带者的精子染色体畸变率分别为12133 %(9/73) 、16118 %(11/ 68) 和15148 %(13/ 48) ,均显著高于健康对照者精子畸变率(4. 35 % ,5/ 115) 。进一步FISH 显示,在1 例慢性迁延型肝炎患者的精子染色体上有特异荧光信号。研究结果表明,HBV 能导致精子染色体不稳定性,并在患者精子染色体上整合,其整合特点是:整合位点是随机的,且大多为多位点整合。

Abstract: Sperm chromosome of subject s with hepatitis B virus infection were prepared using interspecific in vit ro fertilization with zona2f ree hamster eggs. Fluorescence in situ hybridization ( FISH) to sperm chromosome spreads was carried out with biotin2labelled full length HBV DNA. There was significant difference in the frequencies of sperms with chromosome aberrations between subject s with HBV infection and cont rol. FISH showed that HBV DNA integrated into sperm chromosomes , and that multisite and nonspecific integrations were the features of HBV in sperm chromosomes. These result s indicate that HBV infection affect s on the sperm chromosome broadly.

Key words: hepatitis B virus, human sperm chromosome, zona2f ree hamster egg, FISH, chromosome aberration, DNA integration, vertical t ransmission
