Relation between concentration of lead zisc and lysozyme in placentas of women with intraiterine foetal growth retardation.
Intrauterine foetal growth retardation (IUGR) implies increased risk of morbility and mortality of the newborn.
Aetiology of intrauterine retardation is probably multifactorial and may include maternal infection, malnutrition, placental dysfunction, hypertension, toxaemia, smoking, professional and environmental exposure.
The work concentrates on the lead, zinc and lysozyme levels in blood and placental tissues of 50 females in the IUGR group and 43 females from a control group.
Statistically significant differences in zinc and lead levels between the compared group were found.
The IUGR group had lower zinc and higher lead levels.
A significant negative correlation of zinc and lead levels was observed.
We found a statistically significant relationship between lead levels in placental tissues and the age of the pregnant females of the IUGR group higher lysozyme levels were found.
On the basis of the discussed results the authors recommend zinc supplementation during the pregnancy.
