Abstract |
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, hydroxyproline concentration was 11.52 +/- 1.83 micrograms/mg lyophilized tissue, whereas in the other group concentration was 20.29 +/- 4.32 micrograms/mg tissue. These data disclose a much lower collagen placental content in the group with premature rupturing of the membranes.
