title: Temporal organization of the thyroid gland in A/He mice (morphometric investigation).
abstract: Biological rhythms of structural elements of the thyroid gland of A/He mice were studied by morphometric methods followed by spectral amplitude and phase analysis on the Minsk-32 computer. The morphological data show that the activity of the organ is maximal at night. The biorhythms have a complex frequency spectrum, including intradian, circadian, and ultradian components.
