摘要:
Aim:Protective effects of aqueous extract of Amaranthus hybridus against afl atoxin B1(AFB_(1))and/or fumonisin B1(FB_(1))on the H4IIE-luc cell line were determined by use of the methyl thiazol tetrazolium viability assay and disruption of DNA ***:H4IIE-luc cells were incubated with different concentrations of AFB_(1) and/or FB_(1) for 24 and 48 h with or without aqueous extract of ***:AFB_(1) decreased the viability of cells after 24 and 48 h of ***_(50)values for AFB_(1) were 10.5 and 1.8μmol/L for the two periods,*** the 48 h exposure to mycotoxin repeated with a pre-treatment of 20 and 40μg/mL extract of ***,the EC_(50)changed to 3.88 and 7.67μmol/L,respectively.H4IIE-luc cells exposed to FB_(1) for 24 h responded more than those incubated for 48 *** treated with a combination of AFB_(1) and FB_(1) were less viable with a signifi cant decrease in the greater *** mixture of AFB_(1) and FB_(1) resulted in a signifi cant threat to H4IIE-luc as indicated by the absence or appearance of new bands in random amplifi ed polymorphic DNA analysis,which demonstrated damage to *** protective effects were probably due to greater content of total phenolics,carotenoids,β-carotene,folic-,linolenic-,linoleic and palmitic acids,as well as calcium,magnesium,iron,zinc,and selenium observed in the ***:Exposure to 40μg/mL of extract of *** protected cells from damage to DNA by stabilizing DNA.
