    Description / Table of Contents: Summary The content of GPI protein in normal and GPI deficient red cells was studied by immunological methods. In normal cells almost all enzyme protein is catalytically active. In the four inherited variants with non-spherocytic hemolytic anemia studied the content of GPI protein was decreased to a variable degree. Furthermore, the catalytically active portion of GPI protein varied markedly. It can be concluded that in the pathogenesis of this hereditary disorder an increased lability as well as an impaired synthesis of the defective enzyme play a role.
    Notes: Zusammenfassung Mit immunologischen Methoden wurde der Gehalt an GPI-Protein in normalen und defizienten roten Blutzellen untersucht. In normalen Zellen ist nahezu sämtliches Enzymprotein auch katalytisch aktiv. Bei den vier untersuchten genetischen Varianten mit nicht-sphärocytärer hämolytischer Anämie fand sich in allen Fällen eine Verminderung an GPI-Protein in unterschiedlichem Ausmaß. Ebenfalls unterschiedlich war der Anteil des katalytisch aktiven Proteins. Es wird geschlossen, daß bei der Pathogenese des Enzymdefekts sowohl eine erhöhte Labilität des Enzyms als auch eine verminderte Synthese eine Rolle spielt.

    Notes: During the nineteenth and twentieth centuries religion continued to play an obvious role in the Middle East. Among observers of that area the significance of the impact of religion on political development was consequently never minimized to the extent that it was among observers of political trends in the West. Western scholars interested in the Middle East, however, have tended to overrate the importance of the Muslim modernists with whom they felt a certain affinity. They also have accepted too uncritically the views of modernists concerning the lifelessness of traditional expressions of Islam. As a result, not until recently have we begun sufficiently to appreciate traditional Muslim religious leaders both for their impact on and for the diversity of their responses to modern political and intellectual currents. I believe that this diversity is not accidental but rather is susceptible to analysis and explanation. This essay demonstrates how four variables (historical circumstances, theological considerations, socioeconomic considerations, and governmental policies toward Muslim religious leaders) affected the political involvement of the Islamic ulama throughout the Middle East generally and in Tunisia particularly during the ‘liberal age’.

    Description / Table of Contents: Summary In a family of Italian origin, we found four members with a considerable activity of creatine kinase inside their erythrocytes. All other clinical and hematological findings were normal. The enzyme anomaly seems to be inherited in the autosomal mode. The creatine kinase (CK) activity in freshly drawn blood was about 12 U/g Hb. The activity was higher in young red cells than in older ones. Studies with specific antibodies against human CK isoenzymes revealed the CK activity in Offprint requests to: Prof. Dr. H. Arnold (address see above) the probands' red cells to be due to about 90 % to the BB-isoenzyme normally found in brain and nerve tissue. The presence of CK in the erythrocytes does not seem to have any consequences for the energy metabolism of these cells. Creatine concentration was slightly elevated, but creatine phosphate could not be detected.
    Notes: Zusammenfassung Bei vier Angehörigen einer italienischen Familie fanden wir eine erhebliche Kreatinkinaseaktivität in den Erythrozyten. Sämtliche hämatologischen und klinischen Befunde unserer Probanden waren normal. Das abnorme Vorkommen der Kreatinkinase wird autosomal vererbt. In frisch entnommenem Blut hatte die Kreatinkinase eine Aktivität von etwa 12 U/g Hb. Die Aktivität war in jungen Erythrozyten höher als in älteren Zellen. Untersuchungen mit spezifischen Antikörpern gegen die menschlichen Kreatinkinase-(CK)Isoenzyme ergaben, daß die abnorme Kreatinkinase zu etwa 90 % dem BB-Isoenzym entspricht, das normalerweise in so hoher Konzentration nur im Gehirn- und Nervengewebe vorkommt. Die Gegenwart des Enzyms in den Erythrozyten der Probanden scheint keine Bedeutung für den Energiestoffwechsel der Zellen zu haben. Kreatin, das auch in normalen Erythrozyten vorkommt, ist auf etwa das Doppelte erhöht, während Kreatinphosphat genau wie in normalen Erythrozyten nicht nachweisbar ist.

    Description / Table of Contents: Summary Since the first report of GPI deficiency in 1967 many patients from all over the world have been described. The patients suffer from a typical nonspherocytic hemolytic anemia with hemolytic crises during acute infections. The disease is inherited as an autosomal recessive, half of the patients are homozygotic, the others are double heterozygotes. The biochemical properties of the deficient enzymes vary widely. Thus, many well characterized enzymes have been designated as different variants. The modification of physicochemical properties surpasses kinetic aberrations. All defective variants are more or less unstable. The activity diminishes progressively, leading to a rise in G6P concentration and in red cells after aging in vitro to a dramatic impairment of glycolysis and concomittant hemolysis. The cause of the metabolic block is the diminished GPI activity itself and not an inhibition of hexokinase by the high G6P.
    Notes: Zusammenfassung Seit der Erstbeschreibung des GPI-Mangels 1967 wurden zahlreiche Patienten aus allen Teilen der Welt mitgeteilt. Die Patienten leiden an einer typischen nicht-sphÄrozytÄren hÄmolytischen AnÄmie mit krisenhafter Verschlechterung wÄhrend akuter Infektionen. Die Erkrankung wird autosomal rezessiv vererbt, die HÄlfte der Patienten ist homozygot, die anderen doppelt-heterozygot. Die biochemischen Eigenschaften der defekten Enzyme variieren stark, so da\ verschiedene Varianten beschrieben wurden. Die physiko-chemischen Eigenschaften sind hÄufiger verÄndert als die kinetischen. Alle Defekt-Varianten sind mehr oder weniger instabil. Die wÄhrend der Zellalterung fortschreitende Verminderung der GPI-AktivitÄt führt zu einem Anstieg des G6P, und bei in vitro gealterten Erythrozyten zu einem dramatischen Abfall der Glycolyserate und gleichzeitiger HÄmolyse der Zellen. Die Ursache der GlycolyseeinschrÄnkung scheint die Verminderung der GPI-AktivitÄt selbst und nicht etwa eine Hemmung der Hexokinase durch das erhöhte G6P zu sein.

    Notes: Summary Medulloblastoma and acute lymphocytic leukemia patients treated by intrathecal methotrexate and radiation were investigated by means of computerized axial tomography. More than 50% of them turned out to have acquired encephalopathy. Only gross morphologic brain defects, as visualized by computerized tomography, caused manifest clinical signs of brain dysfunction, such as epilepsy, mental retardation, paresis, and apallic syndrome. Mild morphologic changes were found even in asymptomatic children. The preferred site of defects in brain substance was the paraventricular white matter.

    Notes: Abstract A graphic and practical method for displaying renal growth utilizes a growth-hypertrophy chart. It is best suited for following renal growth on sequential intravenous urograms in patients with urinary tract infection, reflux and problems in which renal growth reflects the efficacy of therapy. The chart uses established standards for normal kidney length, and rates of growth and hypertrophy, and enables one to tell at a glance whether the renal growth is normal. Pitfalls both in the method of measuring the renal lengths and in the interpretation of the measurements are discussed.
