    Description / Table of Contents: Summary In a north german family which shows cyanotic members in three generations, it was found that HbM was the cause of the cyanosis. One child was observed from birth. It developed the characteristic cyanosis within a few weeks indicating that the anomaly was in theβ-chain of the haemoglobin. This was shown to be correct by hybridisation of the haemoglobin with dog haemoglobin. The investigation of the tryptic peptides of theβ-chain isolated from globin by counter-current distribution, by „fingerprint”, gave an anomalous peptideβT7. Quantitative amino-acid analysis of this peptide showed that it lacked histidine but contained tyrosine instead, from which it follows that there is an exchange of tyrosine for histidine in position 63 of theβ-chain. This corresponds to the arrangement in HbM Saskatoon.
    Notes: Zusammenfassung In einer norddeutschen Familie, die cyanotische Individuen in 3 Generationen aufweist, wurde HbM als Ursache der Cyanose festgestellt. Ein Kind konnte von Geburt an beobachtet werden; es entwickelte erst im Ablauf einiger Wochen die charakteristische Cyanose. Daraus war abzuleiten, daß die Anomalie in derβ-Kette des Hämoglobins liegen mußte. Dies ließ sich im Hybridisierungsexperiment mit Hundehämoglobin als zutreffend erweisen. Die Untersuchung der Peptide der durch Gegenstromverteilung aus Globin isoliertenβ-Kette mittels „fingerprint“ ergab ein anomales PeptidβT7. Die quantitative Aminosäureanalyse dieses Peptids zeigte, daß darin Histidin fehlte, dagegen Tyrosin vorhanden war, woraus folgt, daß in Position 63 derβ-Kette ein Histidin-Tyrosin-Austausch vorliegt. Das entspricht den Verhältnissen in HbM Saskatoon.

    Description / Table of Contents: Summary Recent work byHuehns et al. gives good evidence that the two prefoetal blood pigments Gower 1 and Gower 2 are normal hemoglobins in the early development of human embryos. These two embryonic hemoglobins with a slow anodic mobility similar to HbC are regulary detected in embryos with a crown-rump length under 10 cm. Chemical properties, polypeptide chain composition and occurrence in the newborn are dicussed by the authors. In this paper the existence of human embryonic hemoglobin is confirmed by starch-gel electrophoresis in blood samples of four young embryos with a crown-rump length ranging from 2.5 to 5.5 cm. In comparative studies embryonic hemoglobins were also found in cow embryos with a crown-rump length between 1 and 7 cm.
    Notes: Zusammenfassung Die vonHuehns u. Mitarb. genauer beschriebenen embryonalen Blutfarbstoffe Gower 1 und Gower 2 ließen sich im Hämolysat des Blutes einer 5,5 cm langen menschlichen Frucht durch die Stärkegelelektrophorese nachweisen. Sie fanden sich außerdem auf der Photographie einer Stärkeblockelektrophorese aus dem Jahre 1960 von Hämolysat einer 3,5 cm langen menschlichen Frucht. Im Blut eines 1 cm langen Rinderembryo wurden neben fetalem Rinder-Hb drei langsam wandernde Hb-Fraktionen festgestellt, die offensichtlich ebenfalls als embryonale Hämoglobine anzusehen sind.

    Notes: [Auszug] Foetal haemoglobins have also been investigated in animals of different species6'7, but embryonic haemoglobins have until now been described only in young chicken embryos8 and in Bufo vulgaris9. The present communication deals with the development of embryonic, foetal and adult haemoglobins in ...

    Notes: [Auszug] In comparison with the adult blood pigment the characteristic alkali stability, slow electrophoretic mobility, and tryptophan band of human HbF were missing in the animal foetal haemoglobins previously examined, with the exception of the rhesus monkey5-7 and the chimpanzee8. The isoleucine content ...

    Description / Table of Contents: Zusammenfassung Wesentlicher Anlaß dieser Publikation war es, auf das Krankheitsbild der α-Thalassämie aufmerksam zu machen und die klinischen und einfachen labortechnischen diagnostischen Möglichkeiten zu erörtern. Es wird über drei Fälle von HbH-Krankheit bei Patienten griechischer Herkunft berichtet, die alle das voll ausgeprägte Bild der Erkrankung mit Hepatosplenomegalie und einer hypochromen, mikrocytären und gleichzeitig hämolytischen Anämie aufwiesen. Bei allen drei Patienten konnte die Diagnose durch den elektrophoretischen Nachweis von HbH bei normalen HbF- und erniedrigten HbA2-Werten bestätigt werden. Das Auffinden von HbH-Innenkörpern in Brillantkresylblau-Präparaten stellt eine ebenso einfache wie wichtige diagnostische Maßnahme dar.
    Notes: Summary It is the main intention of this paper, to draw attention to alpha-thalassaemia and to the clinical and simple laboratory-procedures which are available to make the diagnosis. Three cases of hemoglobin H disease are reported. The patients originate from Greece. All of them presented the typical picture with hepatosplenomegaly, hypochromic, microcytic and concomitantly hemolytic anemia. In all three patients the diagnosis was based on the electrophoretic proof of hemoglobin H with normal value of hemoglobin F and low value of hemoglobin A2. The demonstration of hemoglobin H particles, using brillantkresylbluestainings, is a simple but important diagnostic method.
