[Inhibition of respiration of mitochondria by o-phenanthroline in a constant magnetic field].

: Preincubation of mitochondria treated with chelator of non-heme ferrum o-phenanthroline (0,067-0,267) for 20 min at 18 degrees C in the constant magnetic field of 330 mT brings about a decrease of the intensity of their uncoupled respiration with NAD-dependent substrates by 15-20% as compared to similar mitochondria preparations without the magnetic field effect. The latter is not realized during conjugated respiration with NAD-dependent substrates at uncoupled respiration with succinate, and in the absence of o-phenanthroline as well.
