Abstract

|
This study aimed to examine the alteration of circadian structures of electrolytes, trace elements, and white blood cell homeostasis under the action of stressors factors. Male rabbits were used in experimental work. Four-hour urine and blood specimens were collected over a span of 48?72 hours. Total Na (sodium), K (potassium), Ca (calcium), Mg (magnesium), Cu (copper), and Zn (zinc) were analyzed on atomic absorption spectrophotometer. Rhythm’s parameters have been estimated by the nonlinear least square method for sinusoidal rhythms and by dispersion analysis for nonsinusoidal rhythms. Intact rabbits’ chronoperiodical systems of water-mineral and white blood cell homeostasis were characterized by circadian structures. Acrophases of indices of water-mineral and white blood cell homeostasis in intact rabbits mostly had individual nature. Temporal structure of water-mineral and white blood cell homeostasis in rabbits under the action of stress were characterized by infradian rhythms or nonperiodical oscillations.
