in order to elucidate the mechanisms by which parathyroidectomy ( ptx ) , performed in young spontaneously hypertensive rats ( shr ) , delays the development and attenuates the level of hypertension , we studied , in vivo , cardiovascular reactivity ( cvr , blood pressure response to bolus noradrenaline administration ) , aortic calcium distribution and cardiac calcium content in shr with or without parathyroid glands .
