Superoxide levels and function of cerebral blood vessels after inhibition of CuZn-SOD.
The goal of this study was to examine the role of endogenous copper/zinc (CuZn)-superoxide dismutase (SOD) on superoxide levels and on responses of cerebral blood vessels to stimuli that are mediated by nitric oxide (acetylcholine) and cyclooxygenase-dependent mechanisms (bradykinin and arachidonic acid). Levels of superoxide in the rabbit basilar artery were measured using lucigenin-enhanced c...

The efficacy of antioxidant enzymes to limit oxidant lung injury by instillation with surfactant mixtures in preterm infants with hyaline membrane disease is under investigation. However, there is concern that instillation of proteins in the alveolar space may inactivate pulmonary surfactant. We studied the effects of bovine copper-zinc superoxide dismutase (CuZn-SOD) on the biophysical propert...

AGING, WHICH IS CLOSELY LINKED to oxidative stress, is an independent risk factor for various cardiovascular diseases (1). The role of reactive oxygen species (ROS) such as superoxide (O2 ) in the aging process was initially proposed as the “free radical theory” by Harman in the 1950s (12), whereby ROS attack cellular molecules and cause the functional decline of organ systems, which eventually...
