title: Adrenalectomy aggravates ischemic brain edema in female Sprague-Dawley rats with carotid arteries ligated.
abstract: The effect of adrenalectomy has been investigated in a model of global cerebral ischemia. After bilateral carotid ligation the mortality rate was increased in adrenalectomized rats, and this effect was prevented by glucocorticoid pre-treatment. Adrenalectomy accelerated the appearance of the symptoms of cerebral ischemia, resulting in a moderate aggravation of brain edema and in a significant decrease in the concentration of high-energy phosphate esters. Our findings support the view that endogenous glucocorticoids may play a role in the amelioration of ischemic brain injuries in rats.
