V. V. Ivanov at al. Results o f the study and discussion First we should give attention to specific characteristics of the urinary system functioning. The analysis of changes in daily amount o f samples and daily urine volume demonstrates quasiperiodical mode of the changes, practically in phase ‘behavior’ of the curves and obvious decrease o f their levels during the polar night. Considering the obvious influence of moon phases on various functions of human body [3], we found it reasonable to analyze the dynamics of daily average values of urine samples number (n, 1/day) within synodic month (29.52 days). The fact was confirmed that n minimum appears after new moon (NM) at the first quarter of the Moon (1/4) and n maximum falls onto full moon (FM) and the third quarter (3/4), see Fig. 1 (95% significance level). The analysis of the dynamics of daily average values (averaged by 9 points with sliding average technique) of the indices Ssh (Csh| and Eur (СШ) during the period in question shows that total amount of thiols and urochrome excreted with urine per day and their concentrations have a noticeable positive trend. The changes make 29 mcmole (35 mcmole) and 15 mcmole (18 mcmole), respectively. The fluctuation periods, common for all the studied biochemical indices, which are presented in Table 1, were detected with the spectral Fourier analysis. Table 1. Periods of variations of cosmophysical factors and periodical fluctuations o f biochemical indices (days). SA and geomagnetic activity indices [ 4 ] Disturbance from the Sun [ 1 ] Unithiol half oxidation time [1] Content / concentration of thiols Content / concentration of urochrome 14.8 15.06, 14.63 15.06/13.84 14.22/13.84 27.0±2.0 26.95 28.44/26.95 25.60/25.60 31.8 34.13,32.00 32.00/30.12 32.00/30.12 35.0±1.0 36.57/36.57 36.57/36.57 44.0±1.0 39.38, 42.67 42.67 / - 42.67/ - As we can see, some of the periods are definitely close in their values to the following periods: of variations of solar and geomagnetic activity indices; of fluctuations of unithiol half oxidation time with sodium nitrite in water solutions in vitro; of variations of the main inequations in geocentric ecliptic longitude of the Moon caused by the disturbances from the Sun - evection and variation. Particularly, there are rhythms of biochemical indices (13.84, 14.22, 15.06 and 30.12, 32.00 days), which are close to the periods of the main inequations - variation (14.8 days) and evection (31.8 days). One of the rhythms of solar and geomagnetic activities, 44.0±1.0 days appears as a leading rhythm in all spectra of indices and manifests itself as harmonics with the periods of 39.38 and 42.67 days. The basic rhythm manifests itself most effectively in the fluctuations o f Csh (26.95 days) and Сш (25.60 days). In our opinion, this fact correlates to SA maximum during 2001-2002. Intradaily dynamics of fluctuations of Xsh, Csh, Eur, Cur for all the period of the research and for the periods of polar night and polar day was also studied. 202
