Rhythmicity of specific and nonspecific resistance in adult women.
We studied biological rhythms of immunological parameters and absorption and digestive activities of neutrophils and monocytes in women during the menstrual cycle. Circadian rhythms of phagocytosis were evaluated. The phagocytic system was characterized by highest activity during ovulation and early luteal phase of the menstrual cycle accompanied by physiological immunosuppression. It was shown that macrophages determine the spatial and temporal organization of specific and nonspecific resistance in women. We evaluated phases of the menstrual cycle optimal for studying rhythms of the immune system and phagocytosis.
