Manganese superoxide dismutase (Mn SOD), mitochondrial enzyme, defends against the toxic effects of superoxide radical (O2.-) in pathological processes by catalyzing the conversion of O2.- to hydrogen peroxide (H2O2). The activity of another enzyme, NADH diaphorase, forms the basis for a histochemical method used commonly to demonstrate nerve cell bodies in the enteric plexuses. We found identical patterns of localization of Mn SOD immunoreactivity and NADH diaphorase activity in brain, esophagus, stomach, colon, liver, and kidney. NADH diaphorase enzymatic activity co-migrated with complexes of Mn SOD on a non-denaturing gel. This suggests that the NADH diaphorase may in some way be related to Mn SOD.

D001921 Brain The part of CENTRAL NERVOUS SYSTEM that is contained within the skull (CRANIUM). Arising from the NEURAL TUBE, the embryonic brain is comprised of three major parts including PROSENCEPHALON (the forebrain); MESENCEPHALON (the midbrain); and RHOMBENCEPHALON (the hindbrain). The developed brain consists of CEREBRUM; CEREBELLUM; and other structures in the BRAIN STEM. Encephalon
D004064 Digestive System A group of organs stretching from the MOUTH to the ANUS, serving to breakdown foods, assimilate nutrients, and eliminate waste. In humans, the digestive system includes the GASTROINTESTINAL TRACT and the accessory glands (LIVER; BILIARY TRACT; PANCREAS). Ailmentary System,Alimentary System
D000818 Animals Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.
