We examined the effects of low-level ozone (O3) inhalation on polyamine metabolism and tritiated thymidine (3H-TdR) incorporation into DNA in rat lungs. We have also compared the activities of ornithine decarboxylase (ODC), the rate-limiting enzyme o

A protective effect of butyrate against hyperoxia was found with adult rat pulmonry artery smooth muscle cells. Butyrate (5mM) when added just prior to the hyperoxic exposure (95%) markedly decreased lactate dehydrogenase release from cells during 68

Adaptation to hyperoxia has been attributed to increased activities of protective enzymes, but we suggest that an additional factor may be the lung's capacity to repair itself in hyperoxia. Such repair would require increased polyamines, but there ar

Ornithine decarboxylase activity increases 2-fold above control after 1 day and 25-fold after 3 days of exposure to 0.85 atm oxygen. Putrescine content nearly doubled by 72 hours which may reflect increased activity or ornithine decarboxylase. Spermi

Studies of surfactant following lung reimplantation and transplantation have given contradictory data. Most of these studies have measured surface tension on a modified Wilhelmy balance as an indicator of surfactant but this method has certain limita
