[Protective action of serotonin in relation to oxyhemoglobin during the ultraviolet irradiation of a mixture of their solutions].
It was shown by the spectral method that 5 x 10(-5) serotonin protected native (20 degrees C) oxyhemoglobin (1,48 x 10(-5) M) against UV-irradiation of the mixture (dose 12,4 x 10(4) erg/sm2). Serotonin also displays the protective effect with thermally modified (45 degrees) hemoprotein as the degree photooxidation of oxyhemoglobin reduces in the presence of the radioprotective agent. The cause of the radioprotective effect is attributed to the formation of a serotonin-oxyhemoglobin complex.
