DEHP effects on retinal vessels in newborn rats: a qualitative and quantitative analysis.

Di-(2-ethylhexyl)-phthalate (DEHP), employed in polyvinyl chloride fabrication and released by endotracheal tubes, is known to cause alterations to several mammalian tissues, markedly in immature animals. The high incidence and severity of bronchopulmonary dysplasia and retinopathy in preterm babies submitted to endotracheal intubation prompted us to investigate the effects of DEHP in lung and retina perinatal development. We previously demonstrated that in rats delivered and breast-fed by DEHP-treated mothers lung alveolarisation is severely impaired.
