MORPHOMETRIC-ULTRASTRUCTURAL INVESTIGATIONS ON SUPRAOPTIC NUCLEUS OF DEHYDRATED RATS

The supraoptic nucleus of the dehydrated rat has been analysed by electron microscopy and morphometry. With that it appears, that the relative volumes of the different cell compartments are striking constant. Otherwise one can see an absolute increase of the cell volume together with the cell compartments which take part at the synthesis and secretion of the neurohormones. These results are expression of an accelerated move of the neurosecretory material during increased synthesis. The importance of an optimal standardization of the perfusion-method in investigations of the neurosecretory system is demonstrated. © 1969 Springer-Verlag.
