[The analysis of results of laboratory analyses considering the circannual rhythms].

The technique of cosinor-analysis was applied to study the oncological dynamics of hormonal and lipid status, activity of peroxide oxidation of lipids in 580 healthy males and females residing in the Western Siberia. The clear circannual rhythm of gluco-corticoid function of suprarenal glands, insular apparatus and activity of thyroid system, lipid metabolism and half-year periodicity, of activity of lipids peroxide oxidation are detected. The statistically significant differences of number of indicators in various phases of circannual rhythm are established.
