[A cytogenetic analysis of the antimutagenic action of alpha-tocopherol on spontaneous and radiation-induced chromosomal mutations].

The antimutagenic effect of alpha-tocopherol at concentrations of 1-10(-5)-1-10 mcC/ml was studied with respect to spontaneous and radiation-induced chromosome mutations in Allium fistulosum L. and Vicia faba L. It is established that at these concentrations alpha-tocopherol exhibits a significant antimutagenic activity, decreasing the frequency of chromosome mutations more than by 40-50%. No changes resulting from the antimutagenic effect of alpha-tocopherol were observed in the spectrum of structual mutations of chromosomes.
