Dielectric properties of red blood cells pretreated by different types of vitamins

ABSTRACT

The effect of different vitamins [niacin [B5], pyridoxine [B6], thiamin [B1] and ascorbic acid [c]] on human red blood cells [RBC] in vitro has been studied. The dielectric parameters, electric conductivity, the relaxation frequency and dipole moment were measured over a frequency range from 50 Hz to 100 kHz .These parameters were used to follow up the variations occur in the red blood cells after one hour from incubation with such vitamins. The variations in all parameters are compared with the control specimen [without adding vitamins]. The dielectric parameters [epsilon, epsilon], conductivity [sigma] and dipole moment [D] were found to be decreased in comparison with the control one, while the relaxation frequency increases. The obtained results showed that the used vitamins may cause variations in structure and function of red blood cells, and consequently the risks of using large amounts of these vitamins for long time
