[Infradian rhythms of the thymic morphofunctional state in male Wistar rats]
Abstract:
We carried out a prolonged investigation of thymic cells, melatonin and corticosterone biorhythms in male Wistar rats. The total number ofthymic cells, lymphocyte numbers in the peripheral blood and percentrage of CD3+ lymphocyte had a 6-days period of fluctuation. The other period of fluctuation in 4 days was found in the dynamics width of subcapsular layer of the thymus and inclusion of the thymidine label. Biorhythms of the melatonin and corticosterone levels were in on antiphase and had a 4-days period.
