title: Influence of metaphos on the structuro-functional organization of mitochondrial membranes.
abstract: It has been established by methods of spectrophotometry and spin probe that the organophosphorus pesticide metaphos, widely used in practice, is an inhibitor of NADH2 oxidase of the respiratory chain of the mitochondria and exerts an influence on the structural organization of the mitochondrial membrane. An effect of metaphos on the nature of the distribution and kinetics of NADH2-induced death of monoradical spin probes of various chemical structures was detected in a suspension of submitochondrial particles obtained from beef heart.
