Voorbeelden van antrum

• The cultured follicles developed an antrum, demonstrating that the follicles survived.

• Once the follicle has accumulated a few thousand granulosa cells, a fluid-filled cavity becomes apparent in the extracellular space; this is the antrum.

• Effects of varying gonadotrophin dose and timing on antrum formation and ovulation efficiency of mouse follicles in vitro.

• The oocyte is excentric and there is a dark area where the antrum could form.

• This resulted in a mean final diameter of 471 + 7 m with a high proportion (89%) of antrum formation and healthy appearing oocytes.

• Unexpected oocyte growth after follicular antrum formation in four marsupial species.

• The physical barrier properties of healthy growing follicles can be evaluated by measuring the penetration of plasma proteins in the antrum as a function of their concentration in blood.

• Reversal of anionisation, however, restores their capacity to freely enter the antrum once again.

• They found that the heparin-like compounds are synthesized mainly by the granulosa and theca cells and are released into the follicular antrum, suggesting a process of active secretion.

• Alternatively, antrum, rather than theca cells, may be important for oocyte survival and growth by maintaining the intrafollicular microenvironment and sustaining the integrity of the follicles.

• Growth of preantral follicle was assessed by diameter measurement and antrum formation rate and oocyte growth was assessed by diameter measurement and survival ratio.

• The cyst may invaginate the antrum, but there should be evidence of a cortical boundary between contents of cyst and internal structure of antrum.

• Specifically, it is an inflammation of the mucosal lining of the mastoid antrum and mastoid air cell system inside the mastoid process.

• The antrum is tubular and sclerotized, with the ductus seminalis attaching at its upperside base.

• The portion between the sulcus intermedius and the duodenopyloric constriction is termed the pyloric antrum.
