Transplacental transfer of 2-naphthol in human placenta

open access: yesToxicology Reports, 2015
To determine the transfer of 2-naphthol (2-NPH) in fullterm human placental tissues.Six placentas were studied. The ex-vivo dual closed-loop human placental cotyledon perfusion model was used. 2-NPH was added to the perfusate in the maternal compartment. Samples were obtained from the maternal and fetal up to 360 min measuring.The mean fetal weight was
