ABSTRACT

ABSTRACT

PIP: Hydroxyproline was assayed in 55 placentae, collected at term from clinically normal pregnancies. 30 came from mothers who smoke and 25 from nonsmokers. In the placentae of smokers, hydroxyproline concentration was 42.77 +or- 8.77 mcg/mg of tissue and in those of nonsmokers, 22.52 +or- 7.46 mcg/mg. Such a high difference discloses a large increment in placental collagen production among smokers, which may account for some of the noxious effects of tobacco on pregnancy.
