“…Research works that demonstrate a different cytochemical com position between both types of neurons are especially interesting on this point [Dixon and Herbertson, 1950;Dixon, 1953, 1954: Rodriguez-Perez, 1958: Kroon, 1963Kroon and Goossens, 1967;Tzarnouchanov, 1967;Toledano, 1968, 1969;Kroon et a!., 1971;Martinez-Rodriguez et a!., 1971, 1975aGarcia-Segura et al, 1974].…”

A histochemical study of mucopolysaccharides in the dog spinal cord and dorsal root ganglia is reported in this paper. The histochemical techniques used were the following: PAS, colloidal iron, toluidine blue (pH 5.4 and 3.5), thionine (pH 5.4 and 3.5) and alcian blue 8GX (pH 1 and 2.5). Some histological stains were used also. Two types of neurons could be observed in spinal cord sections stained with colloidal iron techniques. In some neuron a border line of mucosubstances could be seen. In the dorsal root ganglia, different patterns of Nissl bodies distribution in neurons were described. This different distribution of Nissl bodies is associated with different metachromatic colorations of neurons. By using the colloidal iron method, two types of neurons were also revealed in the dorsal root ganglia: some neurons are of a yellow, small-sized and star-shaped type and others are of a light green, larger and round-shaped type. Mucosubstances in the endoneurium and perineurium of nerve fibers, in the Ranvier nodules and in the Schmidt-Lantermann incisures were observed. The possibility that the functional rhythm in some cases might be responsible for the difference in coloration between the dorsal root ganglia neurons is suggested.

“…Die subtile Baker-Färbmethode ist an einige tech nische Voraussetzungen gebunden [Kroon et al, 1971], die es schwer machen, sie unter die routinemässigen Methoden einzureihen. Wir fanden, dass auch übli chere Färbungsverfahren gleichzeitig ein positives und negatives Ergebnis, speziell an den Purkinje-Zellen, ergeben können.…”

Regarding the different stainability when using the Luxol fast blue method, two kinds of Purkinje cells of the rat are described: Luxol-positive and Luxol-negative cells. Since, by this method, phospholipids are demonstrated, the author suggests the prospective varying functional condition of these cells. Different tinction of Purkinje cells has been confirmed also by other methods (gallocyanin-chromalaun, thionine, toluidine blue, lithium-haematoxylin, chromalaun-haematoxylin-phloxine and acid phosphatase) in both animal and human material. After 96 h of immobilization the different stainability of Purkinje cells becomes more marked, which phenomenon can be as well explained with regard to the functional point of view. Similar differences, though less marked, were found also in neurosecretory cells of the nucleus supra-opticus of the rat and in the nuclear region of the ganglion semilunare Gasseri cells in man. Finally, the author refers to the relations between the Luxol blue staining method and Baker’s method employing acid haematoxylin for demonstration of phospholipids in certain kinds of nervous system cells, taking into consideration Kroon’s findings.
