[Nitric oxide in preterm labor].
Synthesis of nitric oxide proceeds in the human myometrium. Decrease of its concentrations can play an essential part in the initiation of uterine contractions in term. Authors suppose, that inhibition of the synthesis of nitric oxide plays a role in premature labour. Concentrations of nitric oxide in women with threatening premature labour were marked. Group I consisted of women with premature departure of amniotic fluid, group II--woman with retained amniotic fluid and with idiopathic contractile activity, group III--woman with departure of amniotic fluid and with idiopathic contractile activity. Concentration of nitric oxide was lower in the group of women with a premature contractile activity in comparison with healthy pregnant women in the same period of pregnancy. Higher concentrations of nitric oxide were observed in the group of patients without contractile activity after departure of amniotic fluid.
