摘要
用当归等13种中药的丙酮提取液对AFB_1、二氨基芴(2-AF)、亚硝基胍(MNNG)、迭氮钠(NaN_3)等致突变物诱导鼠伤寒沙门氏菌TA98,TA100突变株回复突变抑制作用实验。13个样品中有12个呈不同程度的抑制突变作用(占92.3%);其中分别对2-AF有抑制作用占被测样品的84.6%(TA98),61.5%(TA100);AFB_192.3%(TA98、TA100);MNNG23.1%(TA100);NaN_30.07%(TA100)。提示这些中药可能对预防肝癌有意义,但尚待进一步研究。
Possible antimutation effects of 13 preparations of Chinese Traditional Medicinal Herbs on Salmonella typhimurium TA98 and TA100 mutants were tested.2-AF,AFB_1,MNNG and NaN_3 were used as mutagens. The results showed that 12 of the 13 preparations had different degrees of antimutagenic effect in vitro.84.6% of all preparations showed inhibition effect on 2-AF in TA98 mutant and 61.5% in TA100;92.3% on AFB_1 in TA98 mutant and TA100;23.1% on MNNG in TA100 and 0.07% on NaN_3 in TA100.This experiment may be of some help in the study of Chinese Traditional Medicinal herb resources in the preventive measures against carcinogenesis.
