Diatroptov, O. Makarova] Infradian rhythms of esophageal epithelium mitotic activity were studied in male Wistar rats of two age groups: 35-45 days (prepubertal) and 3-4 months (adults). Studies of the time course of esophageal epithelium mitotic indexes in adult males showed 4- and 12-day biorhythms, while prepubertal rats exhibited only 4-day infradian biorhythms of this parameter. Studies of the mitotic activity over long periods (3 years) showed 4.058- and 12.175-day periodicity of infradian biorhythms for this parameter, presumably due to external exposures synchronizing the biorhythms. Studies of the mean daily values of the Bz component of interplanetary magnetic field during the period of our research (2012-2013) showed rhythmicities analogous to changes in the mitotic activity of the epithelium. The minimum mitotic indexes were detected on the days of the most pronounced negative values of the interplanetary magnetic field Bz component.
