[Influence of the pituitary-adrenal axis on the brown fat tissue of the rat and golden hamster].
The suppression or reduction of the adrenal secretion in the Rat and in the golden Hamster results in a reduction of the weight of brown adipose tissue and of the volume of intra cytoplasmic vacuoles. When corticotropin is given to normal and hypophysectomized animals, the intra cytoplasmic vacuolar system and the corticosterone concentration of brown fat increase. After sham hypophysectomy and short ether intake, a considerable lipidic depletion and a high level of corticosterone are observed. The authors speculate that the by adrenaline. The morphologic responses are much more intense and rapid lipid content of brown adipose tissue is increased by corticotropin and reduced by adrenaline. The morphologic responses are much more intense and rapid in brown adipose tissue than in white adipose tissue.
