Brain-derived neurotrophic factor and nerve growth factor concentrations in maternal and umbilical cord blood of opium-addicted mothers.

Background: It is reported that opium consumption during pregnancy is associated with adverse pregnancy outcomes and neurodevelopmental defects in infants. BDNF and NGF alterations during pregnancy cause neurobehavioral deficits in the offspring. The aim of this study was to investigate the effect of opium addiction of pregnant women on BDNF and NGF levels in maternal and umbilical cord blood as well as pregnancy outcome.

Morphine consumption during pregnancy exacerbates neonatal hypoxia-ischemia injury in rats.

Objective: Hypoxia-Ischemia (HI) is the most common cause of death and disability in human infants. The use of opiate in pregnant women affects their children. The aim of this study was to evaluate the effect of morphine consumption during pregnancy and lactation on vulnerability to neonatal HI in rats.
