Abstract

The electrical impedance of DNA of female and male healthy blood samples
was recorded in vitro. The Nyquist Plots for female and male samples were of the same
feature. The peak of each Nyquist Plot was increased and shifted to higher real electrical
impedance values as tobacco concentration increased from 1μl to 4μl. The Bode module
plots confirm these results for female and male DNA blood samples. The start values of
the A.C electrical resistance and electrical capacitance were 95.98KΩ and 2.36μF for
female DNA and were 183.6KΩ and 5.47μF for male DNA, respectively. These values
were changed to be 82.65KΩ and 3.18 μF for female DNA and 177.35KΩ and 5.30μF for
male DNA, respectively, under the effect of 1μl tobacco concentration for each of them.
The increase of tobacco concentration gradually more than 1μl and up to 4μl, these values
reach 139.63KΩ and 5.81μF for female DNA, and 219.42KΩ and 9.00μF for male DNA,
respectively. These results were attributed to the increase of covered area in the lungs
alveolus by the smoke in female and male DNA. Finally, these results illustrate that the
covered areas of the lung alveolus by the smoke were wider in the case of female DNA
than that of male DNA.
