title: Histological changes in the thyroid gland in rats on acclimatisation to simulated high altitude.
abstract: 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.
