本文对３３例慢性乙型肝炎和８例慢性丙型肝炎患者外周血淋巴细胞微核率进行了研究。结果表明，慢性乙型肝炎和慢性丙型炎患者微核率比健康者明显增高（Ｐ＜０．０１）。而慢性乙型肝炎与慢性丙型肝炎患者微核率比较没有差异（Ｐ＞０．０５）。提示丙型肝炎病毒和乙型肝炎病毒对肝细胞和淋巴细胞造成的遗传损伤的机理可能是一致的。
In this paper, 33 cases of chronic hepatitis B and 8 cases of chronic hepatitis C patients with peripheral blood lymphocyte micronucleus rates were studied. The results showed that the micronucleus rate of patients with chronic hepatitis B and chronic hepatitis C was significantly higher than that of healthy controls (P <0.01). There was no difference in micronucleus rate between patients with chronic hepatitis B and chronic hepatitis C (P> 0.05). Suggesting that the mechanism of genetic damage caused by hepatitis C and hepatitis B virus on hepatocytes and lymphocytes may be consistent.
