In 55 placentae, collected at term from clinically normal pregnancies, hydroxyproline was assayed. Thirty were from mothers who smoke and 25 from nonsmokers. In placentae of smokers, hydroxyproline concentration was 42.77 +/- 8.77 micrograms/mg of tissue and in these of nonsmokers 22.52 +/- 7.46 micrograms/mg. Such high a difference discloses a large(More)
Collagen content of 43 placentae from clinically normal females who went into labour spontaneously was determined by assaying hydroxyproline. In 23 cases the membranes ruptured before or at the beginning of labour, and in 20 cases the rupture was intrumentally provoked during the expulsive period. In the group with prematurely ruptured membranes,(More)
Since collagen is one of the main factors responsible for the mechanical properties of soft tissue, we have determined the hydroxyproline content of the placental amnion, the free amnion and the chorion of 32 unruptured and 25 prematurely ruptured human fetal membranes. The hydroxyproline content of prematurely ruptured membranes was approximately 50% lower(More)
The hydroxyproline content of the amnion and the umbilical vessels obtained from cases in which the fetal membranes were instrumentally or prematurely ruptured was assayed. Hydroxyproline concentration (in micrograms/mg) in the latter group was 23.76, 16.79 and 17.86 in the amnion, artery and vein, whereas in the former the corresponding values were 42.20,(More)
