    Description / Table of Contents: Zusammenfassung Bei 3 Patienten, die unmittelbar nach herzchirurgischen Eingriffen verstarben, konnte durch Bestimmung der Wasserstoffionenkonzentration [H+] mit Indicatorpapier am Gefrierschnitt des Herzens 1–2 Std nach dem Tod jeweils eine umschriebene ischämische Schädigung nachgewiesen und das Alter des frischen Herzinfarktes anhand der veränderten [H+] festgestellt werden. Innerhalb der ersten 1–2 Std nach Beginn der Herzmuskelischämie war die [H+] in dem ischämisch geschädigten Bereich erhöht (pH〈6.0). Anschließend wies der Infarktbereich, im Randbereich beginnend, eine erniedrigte Wasserstoffionenkonzentration (pH ∼ 7.4–7.5) auf. Im Zusammenhang mit der erniedrigten [H+] ließ sich mit der Perjodsäure Schiff-(PAS-) Reaktion sogenanntes PAS-positives diastaseresistentes Material im Myokard nachweisen. Beim enzymhistochemischen Succinodehydrogenasenachweis fand sich in einem 7–8 Std alten Infarkt eine verstärkte Enzymreaktion.
    Notes: Summary In three patients who died immediately after surgical procedures on the heart it was possible one—two hours after death to demonstrate with indicator paper on frozen sections of myocardium a circumscribed ischemic lesion and to determine the age of the infarction from the changed hydrogen ion concentration. Within the first one—two hours after the onset of ischemia the hydrogen ion concentration in the area of ischemic damage is increased (pH〈6.0). Subsequently the infarcted area, beginning in the border zone, shows a decreased hydrogen ion concentration (pH appr. 7.4–7.5). As to the decreased hydrogen ion concentration, it was possible with the periodic-acid-Schiff (PAS) reaction to demonstrate so-called PAS-positive diastase-resistant material in the myocardium. The enzymhistochemical succinodehydrogenase test showed an increased enzyme reaction in an infarction which was 7–8 hours old.

    Description / Table of Contents: Summary We carried out determinations of nuclear DNA content and volume of cells of parablastic leukaemia in childhood using bone marrow smears. We also obtained from this slides nuclear volume distribution profiles and DNA distribution samples. We found by first manifestation of the disease both peak and broad basis volume curves. Peak volume curves represent in the main one peak DNA distributions and broad basis volume curves represent either broad basis or two peak DNA distribution samples. By most patients the highest peak was situated between diploid and tetraploid values, accordingly from this values can hyperdiploid aneuploidia be deduced, exactly as other authors have proved through chromosome analysis. In all examined parablastic populations existed a tight positive correlation between the parameters volume and DNA content. By relapse we saw often a conversion of the distribution muster, that is a sharp peak volume curve is converted to broad basis. This change can be explained either through an increase of the DNA synthesizing or greater aneuploid cells or through hold-up in the post-synthetic gap. By populations with hyperdiploid stemlines is the volume peak also situated in the main class K1 or K 1/2. Deviation in the DNA content is not followed by an alteration of the volume, because the nuclear volume is in the main determined through total protein and water content. By patients with volume distribution profiles above three and more main classes allows the difficult volume-DNA relation the guess, that two DNA stemlines side by side exist.
    Notes: Zusammenfassung Durch Messungen in Knochenmarkausstrichen wurden Kernvolumenverteilungsprofile und DNS-Verteilungsmuster kindlicher Parablasten gewonnen. Bei Ersterkrankung fanden sich spitzgipflige und breitbasige Volumenkurven. Den spitzgipfligen Volumenprofilen entsprachen vorwiegend eingipflige DNS-Verteilungen, den breitbasigen Volumenkurven breitbasige oder zweigipflige DNS-Verteilungsmuster. Die bei den meisten Patienten zwischen diploiden und tetraploiden Werten liegenden DNS-Hauptgipfel lassen auf hyperdiploide Aneuploidie der Kerne schließen. Die von anderen Autoren mitgeteilten Ergebnisse der Chromosomenanalysen stehen damit in Einklang. In allen untersuchten Parablastenpopulationen bestand eine enge positive Korrelation der Merkmale Volumen und DNS-Gehalt der Kerne. Im Rezidiv kam es nicht selten zu einem Typenwandel: spitzgipflige Volumenkurven wurden zu breitbasigen. Dieser Typenwandel kann durch Zunahme DNS-synthetisierender und stärker aneuploider Zellen sowie durch prämitotischen Arrest erklärt werden. Auch bei Populationen mit hyperdiploiden Stammlinien lagen die Volumengipfel in den Hauptklassen K 1 und K 1/2. Abweichungen im DNS-Gehalt führen nicht zu meßbaren Volumenverschiebungen, da das Kernvolumen sehr wesentlich durch den Gesamteiweiß- und Wassergehalt bestimmt wird. Bei Patienten mit Volumenverteilungsprofilen über drei und mehr Hauptklassen läßt die komplizierte Volumen-DNS-Beziehung zwei nebeneinander bestehende DNS-Stammlinien vermuten.

    Notes: An attachment to a horizontal goniometer for X-ray powder diffraction at temperatures up to about 2,000°C in a vacuum in the 10−9 torr range is described. Specimen heating is by direct contact to a resistance strip heater with provision for electron beam heating. Temperature measurement is by thermocouple or optical pyrometer. High-temperature parameter measurements on vanadium are presented as one of the examples of the capability of the apparatus.
