title: [Prevention of cAMP stimulation of activity of various oxidative mitochondrial enzymes with lidocaine and aminazine].
abstract: Lidocaine or aminazine (chlorpromazine) injected to rats or incubated with liver mitochondria prevented NAD-isocitrate dehydrogenase and transhydrogenase activation during the subsequent incubation of mitochondria with cAMP. Integrity of mitochondrial membranes is obligatory for manifestation of the drugs effect. Lidocaine and aminazine-induced desensitization of mitochondria to the cAMP action was apparently realized via alteration in the state (and/or composition) of lipid component of mitochondria. The significance of mitochondria sensitivity to cAMP stimulation is discussed.
