Abstract
PREVIOUS investigations have shown that thyroid activity undergoes cyclic variation correlated with the phases of the œstrous cycle. The thyroid gland reaches its maximal activity during the phase of œstrus in rats1,2, rabbits3, ewes4,5, buffaloes6, and cows7. In the case of mice and guinea pigs the picture differs as the activity of their thyroids is low at œstrus8,9. In the present investigation it was decided to study the uptake of iodine-131 by the thyroid glands of female mice at short intervals during the œstrous cycle and correlate it with ovary histological appearance.
