Since the beginning of the latter half of this century, we have received many reports on the electron microscopic structures of renal glomerulus and tubules ; but not on what Goormaghtigh called "Juxtaglomerular Apparatus, " except that on the unusual cells of which Braunsteiner and others described under the title of Juxtaglomerular cells. <BR>According to our observations, in a rat's kidney, there exist such cells as have endoplasmic reticulum around the- nuclei and have mitochondria dotted in 2he cytoplasma, which look like the ones Braunsteiner and others mentioned. <BR>Judging from their forms, we thought we could conclude that these cells work internal secretion producing renin and other substances. <BR>Besides, we found another kind of cells, in the interstitium of the cortex, which has the cell membrane, and round dense bodies, presumably produced in many small vesicles in its cytoplasma, and we also concluded, from the morphological view-point, that this kind of cells might work some internal secretion too. All these make us think of the need of further inquiry, morphological and functional, about such cells as were mentioned above.
