    Notes: Summary A report is presented based on the biochemical and immunochemical studies of various tissues from a 15-year-old boy with a neuronopathic form of Gaucher's disease. Qualitative and quantitative lipid analyses revealed a storage of glucosylceramide. The striking feature was that, employing the usual assay methods, a normal activity of the lysosomal enzyme glucosylceramidase was revealed, despite massive lipid accumulation. Immunochemical assays of hepatic and splenic tissue extracts from this atypical Gaucher's patient disclosed the absence of A1 activator protein, which is necessary for the enzymic degradation of glucosylceramide in vivo. This is the second documented case of a patient presenting with glucosylceramide activator protein deficiency.

    Notes: Abstract A case of Wolman's disease is described in a German infant who died at the age of 4 months. Hepatosplenomegaly, abdominal distention, gastrointestinal symptoms, dyserythropoietic changes in the bone marrow, but not adrenal calcification on X-ray were present. Stored lipid material could be demonstrated in liver, spleen, intestine, adrenals, thymus, kidneys, blood cells, but not in the central nervous system. Cholesterylesters and triglycerides were markedly increased in liver and spleen. Lysosomal acid lipase was found to be decreased in leucocytes and liver to less than 10% of normal, when measured with synthetic and natural substrates.
