title: [Changes in the levels of paramagnetic centers in the mouse liver and a mathematical model of synchronized auto-oscillations].
abstract: Investigations of circadian rhythms in paramagnetic particles (free radicals and metal complexes) (PP) concentration variations in tissues are under continuation. A mathematical model advanced considers PP biorhythms as self-induced oscillations subjected to weak synchronization by an external source, by geomagnetic field intensity daily variations for example. By computation parameters of the model were obtained giving good agreement between the theory and experimental data. Due to the mathematical model the amplitude of external synchronizer influence is ten times less than the self-amplitude of PP biorhythm. The experiment was performed on the normal mouse liver. ESR signals g = 1.94, 2.00 and 2.25 were studied.
