The Free Myo-Inositol of Thyroid Tissue.

Abstract
Bioassay with Kloeckera Brevis yeast has been employed to measure content of free myo-inositol in human, rat, rabbit, sheep and guinea pig thyroid glands. In all species, thyroid/ plasma concentration differentials for free myo-inositol were greater than 100. Chromatographic documentation has also been secured, and the possible significance of the abundant intrathyroidal myo-inositol has been discussed.
