    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: Abstract Coagulation factors were examined in 48 newborns with spesis caused mainly by Klebsiella enterobacteriaceae and E. coli. The first examination revealed increased mean values of fibrinogen, antiplasmin, trypsin inhibitory capacity, factors II and X. Thrombocytes, plasminogen, antithrombin III, alpha 2-macroglobulin and factor V were reduced on average. Serial examinations brought to light turbulent dynamics of the parameters. In most cases the fibrinogen level increased first together with factors II, V and X, and with antiplasmin, and followed by antithrombin III and alpha 2-macroglobulin after several days. Trypsin inhibitory capacity decreases progressively, starting from extremely high levels or after an initial rapid increase. Thrombocytopenia is the last to correct. Close correlations between the fibrinogen level and factors II and X in the initial values, as well as in the course of the disease, point to the dynamics of these components being similar. These findings are reason to believe the pathogenetic importance of the disseminated intravascular coagulation in many cases. Rapid overproduction of components takes place after disseminated intravascular coagulation in sepsis; overproduction has its limits in production capacity and thrombocytopoiesis is the weakest link in newborns. Certain parameters are of low diagnostic significance. Sepsis in newborns is well characterized by the discrepancy between thrombocytopenia and high fibrinogen levels, and thus by the difference between fibrinogen level and thrombocyte count. The value of this criterion in separating healthy newborns and those with respiratory distress syndrome from newborns with sepsis has been proved.

    Notes: Abstract The concentration of plasma fibronectin was determined by Laurell's electroimmunoasay [15] in 75 preterm or term newborns within the first 2 days of life, in 97 healthy infants aged from 3 days to 12 months, in 40 septic infants and in 38 healthy adult subjects. The mean fibronectin concentration in citrated plasma of normal adults was 318±84 ml/l. Healthy eutrophic term newborns 1–2 days old had approximately one-third of the fibronectin concentration of adults. There was no significant difference in the values between healthy term and eutrophic preterm newborns or between eutrophic and hypotrophic newborns. The plasma fibronectin increased strongly over the 1st month of life. No significant difference was observed between fibronectin levels in infant boys and girls. The values in septic newborns and septic older infants were significantly lower when compared with those of age-matched healthy controls. It is speculated that this deficiency, because of linkage to fibrin in disseminated intravascular coagulation or due to increased utilisation as a non-specific opsonin and sequestration at sites of tissue injury, may contribute to organ failure in septicaemia.

    Notes: Abstract The mechanisms leading to rapid invasive growth of malignant gliomas are poorly understood. Expression of the hyaluronic acid (HA) receptor CD44 and adhesion to HA are involved in invasive properties. Our previous studies have shown that malignant glioma cells are able to adhere to extracellular HA. Here we investigated expression of the hyaluronic acid receptor CD44 protein in five human (T98G, A172, U87MG, 86HG39, 85HG66) and two rat (C6, 9L) glioma cell lines. Influence of anti-CD44 antibody and hyaluronidase-preincubation on the HA-binding was determined using HA/BSA (bovine serum albumin)-coated culture plates. While all gliomas were highly positive for CD44 with no differences in the number of positive staining cells, median fluorescence intensity decreased as follows: C6〉T98G〉9L〉85HG66〉 86HG39〉A172〉 U87MG. Using HA/BSA coated culture plates the relative levels of specific adhesion to HA were determined as T98G〉A172〉9L〉86HG39〉U87MG〉 85HG66. C6 cells failed to bind HA specifically. Incubation with anti-human-CD44 MAb significantly decreased HA-adhesion of T98G, A172, 85HG66 and U87MG human glioma cells. However the binding capacity was completely blocked only in 85HG66 cells. The three other cell lines kept a specific HA-adhesion after saturation of the receptor. Hyaluronidase pretreatment markedly enhanced HA-adhesion of C6 and 9L rat glioma cells. These results suggest that (i) HA-adhesion of malignant glioma cells is mainly, but not only, mediated by CD44, (ii) expression of CD44 does not correspond with adhesion capacity and (iii) cell-bound glycosaminoglycans may influence glioma cell adhesion to extracellular HA.

    Description / Table of Contents: Summary Enteritis and pseudoappendicitis are typical manifestations of Yersinia infections in children. This is a report on a child with localised tumourous mesenteric lymphadenitis due to Yersinia enterocolitica persistent for a long time. We found specific antibodies against Yersinia outer membrane proteins repeat-edly in the patients’ serum. Only after a ciprofloxacin therapy for 16 weeks we observed a recovery of our patient. Discussion: Yersinia enterocolitica can be the cause of mesenteric lymphadenitis.
    Notes: Zusammenfassung Yersiniainfektionen manifestieren sich im Kindesalter meist als fieberhafte Gastro-enteritis oder Pseudoappendizitis. Es wird über ein Kind berichtet, bei dem sich die Yersiniainfektion als in der Mesenterialwurzel lokalisierte tumorförmige Lymphadenitis mit langanhaltender Persistenz manifestierte. Die Stellung der Diagnose gelang durch den wiederholten Nachweis spezifischer Antikörper gegen verschiedene äußere Yersiniamembranproteine. Erst nach einer Therapie mit Ciprofloxacin über 16 Wochen normalisierten sich alle klinischen Befunde. Diskussion: Bei der Abklärung einer Lymphadenitis mesenterialis muß auch an eine Infektion durch Yersinia enterocolitica gedacht werden.
