КОЛЕБАНИЯ ХРОНО-ПЕРИОДИЧЕСКОЙ СИСТЕМЫ У КРОЛИКОВ ПОД ДЕЙСТВИЕМ СТРЕССОРНЫХ ФАКТОРОВ / FLUCTUATION OF CHRONOPERIODICAL SYSTEMS IN RABBITS UNDER THE ACTION OF STRESSOR FACTORS

В данной работе изучены изменения циркадной организации электролитов, микроэлементов и гомеостаза лейкоцитов под действием стрессорных факторов. Хроноструктура водно-минерального и лейкоцитарного гомеостаза кроликов в условиях стресса характеризовалась инфрадианными ритмами или непериодическими колебаниями. / In this paper was undertaken for purpose of examining the alteration of circadian organization of electrolytes, trace elements and white blood cells homeostasis under the action of stressors factors. Males of the rabbits were used experimental work (20 intact rabbits and 30 rabbits under the action of stress). 4-h urine and blood specimens were collected over a span 48–72 h. Total sodium, potassium, calcium, magnesium, copper and zinc were analyzed on Atomic Absorption Spectrophotometer. Rhythm’s parameters have been estimated by nonlinear least square method for sinusoidal rhythms and by dispersion analysis for nonsinusoidal rhythms. Intact rabbits’ chronoperiodical systems of water-mineral and white blood cells homeostasis was characterized with circadian structures. Acrophases of indices of water-mineral and white blood cells homeostasis in intact rabbits mostly had individual nature. Chronostructure of water-mineral and white blood cells homeostasis in rabbits under the action of stress were characterized with infradian rhythms or nonperiodical oscillations.
