    Notes: Abstract— Isolated neuronal cell bodies and astroglia of young (15–20-day-old) rat brains were both found to contain small concentrations of a variety of glycosphingolipids, including glucosylceramide, galactosylceramide, sulphatide, dihexosylceramide and gangliosides. These sphingolipids, plus sphingomyelin, were isolated, quantitated and their fatty acid and long chain base patterns determined. These data were compared to similar data obtained on these lipids isolated from whole brain and myelin of rats of the same age range.Glucosylceramide was found in an amount equal to galactosylceramide in neurons, and accounted for 35 per cent of the total monohexosylceramide in astroglia. Dihexosylceramide was present in nearly the same amount as sulphatide in both cell types.The sphingolipids of each cell type had characteristic fatty acid patterns. Generally the whole brain fatty acid patterns resembled those of astroglial lipids rather than neuronal lipids. In no case did the cell sphingolipid fatty acids resemble those of myelin. However, the galactosylceramide and sulphatides of both cells had unsubstituted and α-hydroxy acids, both of which had appreciable quantities of C24 acids.The ganglioside fatty acids of each cell type were similar and not unusual, but were quite different from those of glucosylceramide and dihexosylceramide; the latter having appreciable quantities of 16:0 and acids longer than 18:0. The ganglioside patterns of these cells were similar and only slightly different from that of whole brain. Long chain bases of sphingolipids were mainly C18-sphingosine in both cell types, and those of ganglioside and sphingomyelin contained small amounts of C20-sphingosine.

    Description / Table of Contents: Summary The case has been presented of a Japanese aged 22 who was suffering from hereditary non-spherocytic haemolytic anaemia. This was a constant type of anaemia associated with reticulocytosis, jaundice, and glucose-6-phosphate dehydrogenase deficiency of the erythrocytes. Although it was not possible, owing to the absence of enzymic activity, to estimate isoenzyme in the patient's erythrocytes, the isoenzyme was assigned, in the patient's mother and in other members of his family, as well as in controls, to the B type. Cytochemical investigations revealed the presence of a cellular mosaic in the patient's mother who was heterozygous, but in the patient, as well, who himself was hemizygous.
    Notes: Zusammenfassung Es wird über einen 22jährigen Japaner mit einer hereditären, nichtsphärozytären hämolytischen Anämie berichtet. Es bestand eine konstante Anämie mit Retikulozytose, Ikterus und Mangel an Glucose-6-Phosphat-Dehydrogenase in den Erythrozyten. Obwohl der Nachweis von Isoenzym an den Erythrozyten des Patienten wegen fehlender Fermentaktivität nicht gelang, konnte es bei der Mutter, bei den übrigen Familienangehörigen und bei Kontrollfällen dem Typ B zugeordnet werden. Cytochemische Untersuchungen ergaben das Vorliegen eines Zellmosaiks in der heterozygoten Mutter des Patienten, jedoch auch im hemizygoten Patienten selber.
