    BURSTING PRESSURE AND COLLAGEN CONTENT OF FETAL MEMBRANES AND THEIR RELATION TO PREMATURE RUPTURE OF THE MEMBRANES (1980)
    Oxford, UK : Blackwell Publishing Ltd

    Notes: The collagen content and the bursting pressure of human fetal membranes was measured for full term spontaneously ruptured, full term artificially ruptured and prematurely ruptured membranes. The bursting pressure of the prematurely ruptured membranes was significantly higher than the membranes which ruptured spontaneously at term. No significant difference was found in the collagen contents.

    Ultrastructural studies on the nucleoli of the follicle cells in the Lizards Acanthodactylus scutellatus hardyi and Eremias brevirostris (1981)

    Notes: Summary The ultrastructure of the nuclei in the ovarian follicular cells has been examined in the lizards Acanthodacylus scutellatus hardyi, and Eremias brevirostris. During certain growth stages, the nuclei of the intermediate and the pyriform cells become large and conspicuous, and usually contain numerous morphologically variable nucleoli. The latter may be nucleolonemal, compact, ring-shaped, “filamentous”, “fine-filamentous”, “amorphous” or “course-granular” in type, and the number and type in each nucleus seems to be related to the developmental stage. The type of nucleolus may indicate different phases of activity in the nucleus and may also suggest an association with the production of different types of RNA.

    Full-term and prematurely ruptured fetal membranes (1981)
    Springer
    Cell & tissue research 220 (1981), S. 263-278

    ISSN: 1432-0878

    Notes: Summary The layers of the human amnion and chorion were examined by light and transmission electron microscopy. Comparisons among different anatomical sites with respect to full-term and prematurely ruptured membranes indicate that (a) the thickness of the membranes is reduced near the rupture point; (b) intercellular canals near the implantation site become dilated and branched; (c) the trophoblast layer of full-term membranes is thinner and with more degenerating cells; and (d) the fibroblast and spongy layers have fewer collagenous fibers and less organization near the rupture site. These findings suggest that, although cellular activity is maintained in prematurely ruptured membranes, the mainly collagenous extracellular matrix undergoes marked disorientation. If this occurs too early in gestation, it may lead to premature rupture.
