Abstract:
Objective To study the antagonism of water-soluble compounds of salvia-salvianolic acid A(SalA),salvianolic acid B(SalB) and catechu aldehyde(CA) to Cr(Ⅵ) induced genetic toxicity in Vicia faba root tip cells.Methods The root tip of Vicia faba were treated with SalA,SalB,CA(5-1000 ?g/ml) and every compound combined with 100 ?g/ml Cr(Ⅵ) respectively,and with distilled water as control group.The micronucleus rate(MNR),the mitotic index(MI) and the chromosome aberration rate(CAR) of Vicia faba root tip cells were observed by micronucleus assay and chromosome aberration assay.Results Compared with control group,treatments of 50,100 ?g/ml SalA,50 ?g/ml SalB,100,500 ?g/ml CA significantly increased MI(P
