Histological changes in the thyroid gland in rats on acclimatisation to simulated high altitude.
Histological examination of thyroid glands from rats exposed to simulated high altitude has shown an increase in the amount of colloid and a decrease in the amount of epithelium when compared with the thyroid glands from rats kept at sea-level atmospheric pressure. These changes suggest a reduced thyroid activity in animals exposed to simulated high altitude.
