Effect of smoking on ceruloplasmin and its ferroxidase activity in pregnant women.

This study deals with the effects of smoking on serum ceruloplasmin and its ferroxidase activity in pregnant women. The mean value (+/- SD) of serum ceruloplasmin in women smokers during pregnancy is significantly higher (p < 0.01) in comparison to that of nonsmokers, whereas the ferroxidase activity of ceruloplasmin in smokers is not significantly different from that of nonsmokers. These findings suggest that ceruloplasmin in women smokers loses part of its ferroxidase activity.
