PECULIARITIES OF SEASON BIORHYTHMS IN DIFFERENT PARTS OF FUNCTIONAL SYSTEM MOTHER-PLACENTA-FETUS IN DEPENDENCE ON ITS STEREOFUNCTIONAL ORGANIZATION IN PHYSIOLOGICAL AND COMPLICATED PREGNANCY

Abstract

Purpose: studying seasonal periodicity of stereoisomerism of uteroplacental complex, the dynamics of body weight of infants, studying the chronostructure of mezorhythms of contractive activity of right and left parts of the uterus.Material and Methods: We analyzed 2215 pregnancy stories and birth stories retrospectively. We analyzed the pregnancy flow and childbirth peculiarities, weight and growth rates of newborns. the results of mechanohysterographic of the uterus contractive activity, ultrasound investigation was also taken into account.Results: Duration of seasonal biorhythms Increase in the number of women with uterine activity, both its localized homogeneous forms, and bilateral generalized contractions (typical for preterm labor), occurred every 7 months. . The increase in the number of large children was observed in autumn and winter, in summer more children were born with low birth weight.Summary: Environmental factors, varying in different seasons of the year, affect functional processes in the various parts of a functional system «mother-placenta-fetus» through the epiphyseal-hypothalamic and central-peripheral relationships, promoting the initiation of uterine activity, accelerating or decelerating the process of maturation of the fetus, and can also influence the periods of preparedness the body for labor and birth character themselves.
