Note. Variation coefficient of V < 33% for all indices.
The coefficient of variation in the statistical analysis was less than 33% for all investigation indices depending on the season which is testimony to homogeneity of the data totality. Single – factor dispersion analysis of the seasonal influence on the protein indices for donors of plasma for fractionation showed their variability according to the following criteria: albumin, aggregate globulins, 1- globulins and 2- globulins in males and females, as well as – globulins in females. But the degree of this influence was not considerably significant as a whole. The greatest degree of this influence depending on the seasonal factor was established for 2- globulins and – globulins in females: = 0,58 and = 0,12, accordingly.
Expressed in percentage, the index for the degree of the seasonal factor influence on 2- globulins was 58%, on – globulins 12%, on 1- globulins 9% in females. The greatest degree of the seasonal factor influence was 10% for 2- globulins and 7% for 1- globulins in males.
The data tabulated in the table show that the content of general protein in females was lowest in the spring, highest in the summer and autumn. The level of albumin both in females and males was highest in spring and lower in summer.
A pronounced seasonal effect was seen in the total values for globulins: the concentration was high in summer and low in spring. It should be marked in this case that the seasonal redistribution of the globulin fractions is somewhat different: high values of 1- globulins, substantiated by a dispersion analysis, were registered in the donors of both sexes in the autumn, 2- globulins in the summer and autumn and low values were in winter, – globulins in the winter, in the summer and in the spring accordingly.
