title: Relationships between the small ions in the atmosphere and the circadian and circannual biorhythm of the rabbit and rat thyroid.
abstract: Studies on rats and rabbits revealed the reverse type of correlation existing between the amount of small ions in the atmosphere and the circadian and circannual biorhythm of thyroid RNA and blood PBI. Besides other factors of the climatic-meteorologic complex the ionic charge of the surface air seems to be implied in maintaining and synchronizing the basic thyroid biorhythm genetically determined.
