本文报道在利用树建立感染人乙型肝炎病毒（ＨＢＶ）模型，以及进行ＨＢＶ和（或）黄曲霉毒素Ｂ１诱癌实验研究中，摸索出的反复对树肝活检技术。对７６只树进行３６３例（次）肝切手术，其中有４９只树每只反复肝活检６次，有１６只每只反复肝活检７次。相邻两次手术间隔为２个月。没有１例因手术而死亡。亦没发现严重的术后并发症。肝活检所获取的标本可以进行多项检查。表明该技术是对树进行动态肝活检的既安全又简便的方法。
This paper reports the repeated use of tree liver biopsy technique in the establishment of a model of hepatitis B virus (HBV) infection in tree shrews and in the experiment of inducing HBV and / or aflatoxin B1 to induce cancer. A total of 363 tree resections of 76 tree shrews were performed, of which 49 tree shrews were subjected to repeated liver biopsy 6 times, 16 of which were subjected to repeated liver biopsy 7 times. Adjacent two surgical interval of 2 months. No one died of surgery. No serious postoperative complications were found either. Liver biopsy obtained specimens can be a number of checks. This technique is a safe and easy way to perform dynamic liver biopsy of tree shrews.
