Abstract: | Glycyrrhiza Uralensis (GU) and Chelidonium Majus (CM) (25, 50, 100, 200 mg/plate) have obvious blocking effects onSalmonella Typhimurium strains (TA97, TA98, TA100, TA102) mutagenesis induced by aflatoxin Bl (AFB1). The blocking rates of GU and CM are more dependent on the doses. A compound of GU and CM, called Wei Lingsu (WLS), could impede chromosomol aberrations and sister chromatid exchanges (SCE) of human peripheral lymphocyte induced by AFB1, at the concentrations of 1–50 mg/ml, the blocking rates are 52.94%–88.24% and 15. 50%–38.23% saperatly. WLS could also impede the inhibition of AFB1 to lymphocyte mitosis. |
