人乙型肝炎病毒(HHBV)在原发性肝癌(PLC)发生上可能与黄曲霉毒素B_1有协同作用。经158周实验,41只喂黄曲霉毒素B_1的树鼩中,17只感染了人乙肝病毒,24只未感染,前者有9例发生PLC,后者只有3例发生PLC。9只未接触AFB,但已感染HHBV的树鼩,在83周时有1只发
Human hepatitis B virus (HHBV) may have a synergistic effect with aflatoxin B1 in the occurrence of primary liver cancer (PLC). After 158 weeks of experiment, of the 41 tree shrews fed with aflatoxin B_1, 17 were infected with human hepatitis B virus and 24 were uninfected. The former had 9 cases of PLC and the latter only 3 cases of PLC. Nine tree shrews that had not been exposed to AFB but had been infected with HHBV, had one hair at 83 weeks
