Radioprotective potential of astaxanthin after gamma-irradiation of human peripheral blood lymphocytes' cultures in vitro in dose 1.0 Gy on the post synthetic (G2) stage of the first mitotic cycle has been studied. The lack of astaxanthin modifying effect on stage G2 has been demonstrated. No significant changes in the total frequency of chromosomal disorders and in the spectrum of chromosomal aberrations are detected. The comparison of astaxanthin effects between stage G2 and G0 of the cell cycle is conducted.
