title: [Diurnal rhythm of the total antioxidant activity of saliva of children with chronic viral hepatitis].
abstract: The diurinal rhythms of a total antioxidant activity of a saliva were investigated depending on activity of the inflammatory process in a liver of children with chronic virus hepatitis HBV and HCV. The circadian rhythms were found desynchronized, which was showed in lowering of the mesor value, oscillations amplitude, and a rhythm inversion and transformation, as an additional biorhythmological criterion of the presence of the chronic hepatitis of a viral etiology. A tendency of a circadian rhythm to remain with a daily acrophasis but with a law level of amplitude oscillations and a mesor was to be observed after the treatment of children with inactive HBV. By an active HBV a circadian rhythm with it's inversion has been renewed. It was determined the remaining of an ultradian rhythm with increasing level of amplitude oscillations after the treatment of inactive HCV. The law amplitude oscillations and a insignificant increasing of a meror level were characteristic for the circadian rhythm of total AOA of the children with active HBV. It was proved the possibility of usage of the biorhythmological parameters of diurinal rhythms of total AOA as a criteria of efficiency of the conducted therapy for the given group with disease children.
