Thyroid and adrenal responses to the dynamics of meteorologic factors.

Endocrine reactions are essential elements in bodily adjustment to external environment. The study of the endocrine-hormonal mechanisms of adjustment to the dynamic influences of natural factors has a place of its own in contemporary biology. The endocrine functions, like any other physiologic processes, do not take place with constant intensity. The variations occur rhythmically connected to various time-intervals: light-darkness, moon phases, the multi-annual succession of astronomical phenomena, seasonal dynamics of the climate-meteorological complex, a.s.o. This paper deals with the results of some biorhythm and biometeorological researches carried out by us on white Wistar rats, brown cows, rams and wethers.
