[The biorhythmology of primary and superinvasive opisthorchiasis. Seasonal changes in the circadian activity of the cyclic nucleotides and of the key enzyme of the pentosephosphate cycle (G-6-PD) in the peripheral blood of golden hamsters].
570 males of golden hamsters were divided into 3 groups: I--free from invasion, II--once infected, III--repeatedly infected. Diurnal activity of cyclic nucleotides and enzyme of pentose-phosphate cycle (G-6-PhDG) was investigated in spring, autumn, and winter at 3, 7, 11 a.m. and 3, 7, 11 p.m. The golden hamsters once infected with opisthorchiasis do not show any seasonal changes in G-6-PhDG activity, but this invasion influences the total content of protein, diurnal oscillation of which depends upon seasons. In spring time the repeated invasion induces the diurnal rhythms of G-6-PhDG and of total protein content. Diurnal stereotype of cyclic nucleotides (cGMP, cAMP) demonstrates the dependence upon seasons and invasion frequency without any changes of the average diurnal level.
