Lung injury is generated from the early stage of hyperoxia through the biologic effects of cell death and inflammatory response, which eventually leads to evolution of bronchopul-monary dysplasia. Therefore, a protective measure against hyperoxia-induced lung injury is needed. The present study observed that anti-inflammatory cytokine, interleukin-10 had protective effects on newborn rat lungs from injury induced at the early stage of hyperoxia, by preventing cell death and down-regulating inflammatory response.
Effect of Resuscitation with High Concentration Oxygen on a Rat Model of Neonatal Hypoxic-Ischemic Brain Injury

Purpose : This study was undertaken to determine whether any features of apoptosis would occur in the established model of cerebral hypoxia-ischemia in neonatal rats. It was also undertaken to evaluate the effect of post-insult hyperoxia on hypoxic ischemic cerebral injury. Methods : Seven-day-old neonatal rats underwent unilateral carotid artery dissection followed by 2 hours of hypoxia. To this end...

We studied the effects of chronic hyperoxia (>95% oxygen for 14 days) in change of body weight, wet to dry ling weight ratio, and morphologic changes of lung tissue compared with that of room air (21% oxygen for 14 days) in Sprague-Dawley neonatal rat pups. The results were as follows: 1) In neonatal rat pups exposed to room air (normoxia group), body...
