Effect of Smoking on Serum Concentrations of Total Homocysteine, Folate, Vitamin B<sub>12</sub>, and Nitric Oxide in Pregnancy: A Preliminary Study

Abstract

In the light of our findings, we propose that smoking might enhance the vasoconstrictor capacity in pregnant women by increased tHcy concentrations and by a simultaneous decrease in the production of NO which is a vasodilator compound.
