    Description / Table of Contents: Summary A high-risk pregnancy for X-linked recessive inherited Lowe's syndrome was terminated due to a male karyotype in the cultured amniotic fluid cells. The eyes of the male fetus showed specific cataracteous changes of the lens. A posterior lenticonus was due to a defect of the lens capsule. The lenses were of normal size. Loss of lens material through a lens capsule defect could account for the small discoid lens usually seen in Lowe's syndrome. Amino acids in amniotic fluid had normal concentrations except lysine and proline which were markedly elevated.
    Notes: Zusammenfassung Bei einer Schwangeren, die bereits einen Jungen mit Lowe-Syndrom hat, wurde eine Amniocentese durchgeführt. Die Schwangerschaft wurde unterbrochen, nachdem sich in den kultivierten Zellen der Amnionflüssigkeit ein männlicher Karyotyp zeigte und damit eine Wahrscheinlichkeit von 50% für die Geburt eines weiteren Kindes mit dieser X-chromosomal rezessiv erblichen Erkrankung bestand. Der männliche Fet bot die für das Lowe-Syndrom charakteristischen Linsentrübungen. Es bestand ein Lenticonus posterior mit Defekt der hinteren Linsenkapsel; die bisher bekannte kleine, discoide Linse des Lowe-Syndroms entsteht somit möglicherweise durch Verlust von Linsenmaterial bei defekter hinterer Linsenkapsel. Die Aminosäurenkonzentrationen im Fruchtwasser waren mit Ausnahme von deutlichen Erhöhungen von Lysin und Prolin normal.

    Notes: Abstract The first patient of Turkish descent with hyperdibasicaminoaciduria is described. Recurrent diarrhea was observed only during the first three months of life. The infant exhibited low plasma levels of ornithine and arginine. Intestinal absorption of lysine was decreased. Hyperammonemia was noticed only after an i.v. alanine load. It was prevented by addition of arginine.

    Notes: Abstract Ten infants with intractable diarrhea, celiac disease and small bowel resection were treated with a special dietetic regimen called “Baustein” principle. The three major food constituents were added to the formula stepwise: first glucose and maltodextrin followed by protein and vegetable oil or MCT oil. The protein source was a newly developed casein hydrolisate also containing minerals, trace elements and vitamins.

    Notes: Summary The kinetic characteristics of galactose-1-phosphate uridyltransferase and galactokinase in cultivated fibroblasts and amniotic fluid cells were investigated. The K m values of galactokinase for galactose at 2.0 mM ATP are 0.34 mM in amniotic fluid cells and 0.48 mM in fibroblasts. The K m values for ATP at 0.5 mM galactose are 1.25 mM and 2.10 mM. Transferase and galactokinase activities and protein content increase logarithmically during the growth of cultivated cells. The specific activity of both enzymes also increases and reaches a maximum level 10–15 days after subculture. The specific activity of transferase increases faster than that of galactokinase in the case of amniotic fluid cells. In the case of fibroblasts the specific activity of galactokinase increases faster than that of transferase.

    Notes: Abstract Deficiency of acid 1,4-α-glucosidase (EC 3.2.1.20) is associated with Pompe's disease (McKusick 23230), generalized glycogen storage disease type II. The deficiency of this enzyme has been demonstrated in various human tissues and cultivated cells from patients with Pompe's disease. Prenatal and postnatal diagnosis of this genetic disorder can be established by a simple procedure measuring the enzyme activity even with artificial substrates. However, there remain some questions concerning enzyme characteristics of α-glucosidase in various human tissues and the changes occurring during development.
