Alterations of atrial natriuretic factor in mammillary bodies and median eminence from hypertensive and experimental brain hemorrhage rats.

The results of the present study demonstrate that atrial natriuretic factor (ANF) in the mammillary bodies has a dynamic change, while ANF in the median eminence is relatively constant in the course of the increase of blood pressure. It suggests that ANF in the mammillary bodies might take part in the regulation of blood pressure and ANF in the median eminence mainly participates in the functional regulation of the adenohypophysis.
