Nucleus paraventricularis of a senile woman died of bleeding in the medulla oblongata was histologically examined by means of Gomori's chrome-alum hematoxylin and phloxine method. Neurosecretory material was rare within the cells of the nucleus, while intracellular vacuoles and perinuclear clear area were observed, and cells with red pyknotic nuclei were occasionally found. Brief comments were made with respect to the present finding with reference to the secretory activity of the nucleus.
