The aim of the study was to evaluate the influence of maternal smoking on kynurenic acid (KYNA) levels in venous and arterial umbilical cord blood of neonates. Statistically significant lower concentration of KYNA in umbilical arterial blood of smoking mothers neonates was observed. The lower levels of KYNA in blood may reflect the smaller resistence of neuronal tissue to damages under hypoxic-ischemic conditions in neonates affected during intrauterine life by smoking.
