The passage of foetal colonic contents in the amniotic cavity
causes the MSAF and is a commonly encountered finding in the obstetric practice with an overall frequency between 12% and 19%.8,9 It is more common in post-term pregnancies and with intrauterine growth restriction.10 The MSAF is associated with a lot of adverse outcomes and has long been considered to be a bad predictor of foetal outcome.11,12 The MAS is the most common cause of respiratory disease in terms of infants13 and has been reported in 6.6% to 30% of cases of MSAF, and 1% to 3% of liveborn infants.14 The MSAF causes low apgar score at birth, foetal academia and hypoxia.
Hypertension was most common among the youngest and oldest mothers (affecting 8% and 11%, respectively), and rates of tobacco dependence and infection of the amniotic cavity
declined with age (from 2-3% among teenagers to less than 2% among women aged 40 or older).
(14,15) The sphere-derived cells were then transplanted into the amniotic cavity
of the embryonic chicks prior to gastrulation to determine their pluripotentiality.
At the indicated times (15th-18th weeks of gestation), we collected 500 [micro]L of amniotic fluid from the amniotic cavity
and immediately centrifuged it at 900g for 10 min; the supernatants were then stored at -70 [degrees]C until measurement.
In a prospective study he and his associates divided 41 pregnant women into four groups according to the presence or absence of inflammation in the amniotic cavity
, fetus, both compartments, or neither.
But it will need a better system, and on Day 8 another space appears in the cell cluster; the amniotic cavity
, in which the foetus will float in a fluid-filled sac.
