Superoxide dismutase reduces injury in many disease processes, implicating superoxide anion radical (O2-.) as a toxic species in vivo. A critical target of superoxide may be nitric oxide (NO.) produced by endothelium, macrophages, neutrophils, and brain synaptosomes. Superoxide and NO. are known to rapidly react to form the stable peroxynitrite anion(More)
This study evaluated the transverse strength (rigidity) of three groups of sagittal split osteotomies performed in vitro in fresh sheep mandibles. Fixation was accomplished utilizing two different position screw techniques and a monocortical plate technique. Osteotomies fixed with three 2.0-mm screws in an inverted-L pattern and those fixed with one(More)
