Abstract
The experiments were carried out on male Wistar rats aged 6, 12 and 24 months, over the four seasons of the year. Analysis of the results ob tained in all age groups disclosed that changes in activity of the p.a .S (periodic acid Schiff) reaction and in concentrations of Mg and Ca in the liver showed rhythmic oscillations with a period of 12 hours. T he maximal p.a.S reaction activity and of Ca and Mg levels were genera lly found to coincide throughout all seasons and in all age groups. Th e rhythms of change in these parameters in 12- and 24-month-old rats s howed a phase shift as compared to the 6-month-old animals.
