The response of the adrenal cortex to low temperature in relation to the length of the exposures is studied. The morphological changes of the adrenal cells, mainly in the Zona fasciculata, are examined. Thirty white rats of both sexes, divided into six groups, were exposed during time intervals of different lengths to temperatures ranging between – 12° and – 15°C. The cellular modifications encountered by means of the electron microscope at the level of the mitochondria, the smooth endoplasmic reticulum and the liposomes are analyzed and compared with the functional situation of the gland in an effort to establish the existence of a correlation between the morphology and the function.

In order to show the correlation, all images were acquired during selective angiography, resulting in mild blurring and the presence of contrast bubbles on TEE. MV are also shown in Movies S1,S2. CT, computed tomography. IMAGES IN CARDIOVASCULAR MEDICINEAdvance Publication by-J-STAGE
