    Description / Table of Contents: Summary Purpose of this study was to evaluate the clinical utility of intraoperative echocardiography in the assessment of surgical repair of congenitally malformed hearts. In 235 of 508 patients who underwent cardiac surgery during a one year period transesophageal intraoperative echocardiography was performed. This was done to exclude residual ventricular septal defects or right ventricular outflow tract obstruction (n=84), to evaluate results of AV valve reconstruction (n=61), to assess ventricular function following arterial switch operation for complete transposition or in complex heart defects palliated by a Fontan-type procedure (n=50), to assess repair of left ventricular outflow obstruction (n=22) and for miscellaneous defects (n=18). Residual defects leading to immediate reoperation during the same surgical session were found in 4 patients (1.7%), minor residual defects not requiring reoperation were present in 6 patients (2.6%). In 2 patients with complete AV septal defect the left AV valves were only mildly regurgitant immediately after reconstruction but subsequent suture deshiscence required later reopoeration. Echocardiographic data were supplemented by direct pressure measurements in the ventricles and contrast injection into the left atrium. We conclude that intraoperative echocardiography can provide useful clinical informations, if its findings are interpreted in context with pressure measurements and contrast injections.
    Notes: Zusammenfassung Zweck dieser Studie war, den klinischen Nutzen der intraoperativen Echokardiographie bei Patienten mit angeborenen Herzfehlern zu untersuchen. Von 508 während des Zeitraumes eines Jahres durchgeführten Operationen bei angeborenen Herzfehlern wurde bei 235 (47%) eine intraoperative Echokardiographie durchgeführt. Die Indikationen waren Ausschluß von residuellen Ventrikelseptumdefekten und residuellen rechtsventrikulären Ausflußbahnobstruktionen (n=84), Evaluation von AV Klappenrekonstruktionen (n=61), vorwiegende Evaluation der Ventrikelfunktion nach arterieller Switchoperation bei kompletter Transposition oder bei Palliation komplexer Herzfehler durch eine Fontanoperation (n=50), Untersuchungen nach Operation einer linksventrikulären Ausflußbahnobstruktion (n=22), sowie sonstige Operationen (n=18). Residuelle Defekte, welche zu sofortiger Reoperation in der gleichen Sitzung Anlaß gaben, wurden bei 4 Patienten (1,7%) gefunden, unbedeutende residuelle Defekte, die keine Reoperation erforderlich machten bei 6 Patienten (2,6%). In 2 Fällen wurden bei korrigierten kompletten AV Septumdefekten unmittelbar postoperativ geringe Insuffizienzen der linken AV Klappe gesehen, welche später so an Schweregrad zunahmen, daß spätere Reoperationen notwendig wurden. Die durch die transösophageale Echokardiographie erhobenen Befunde wurden durch direkte blutige Druckmessungen und Kontrastinjektion in den linken Vorhof ergänzt. Wir schlußfolgern, daß die intraoperative Echokardiographie klinisch sinnvolle Informationen liefern kann, wenn die erhobenen Befunde im Kontext mit den oben aufgeführten anderen Messungen interpretiert werden.

    Description / Table of Contents: Summary We report on a 28 year-old woman with congenitial ventricleseptum defect and Eisenmenger-reaction who developed acute GvHD on 10th postoperative day after successfull heart lung transplantation. The patient died on the 34th postoperative day of dissociated brain death after intracerebral bleeding.
    Notes: Zusammenfassung Wir berichten über eine 28-jährige Patientin, die aufgrund eines Ventrikelseptumdefektes (VSD) mit Eisenmengerreaktion und nachfolgender Herzinsuffizienz NYHA-Stadium IV herz-lungen-transplantiert wurde und an den Folgen einer akuten GvHD am 34. postoperativen Tag verstarb.

    Notes: The greenbug, Schizaphis graminum (Rondani), is the most economically damaging aphid pest of wheat in the southern Great Plains of the USA. In this study, the single, dominant greenbug resistance gene, Gb3, was molecularly tagged and genetically mapped using amplified fragment length polymorphism (AFLP) and simple sequence repeat(SSR) markers. Three AFLP loci were associated with the Gb3 locus in linkage analysis with 75 F2:3 families from the cross between two near-isogenic lines (NILs) for Gb3,‘TXGBE273’ and ‘TXGBE281′. Two of these loci, XMgcc Pagg and Xmagg Patg cosegregate with Gb3 in the population analysed. Further analysis indicated that XMgcc Pagg and Xmagg Patg are specific for the Gb3 locus in diverse genetic backgrounds. Two SSR markers, Xgwm111 and Xgwm428 previously mapped in wheat chromosome 7D, were shown to be linked with Gb3, 22.5 cM and 33.1 cM from Gb3, respectively, in an F2 population of ‘Largo’בTAM 107’, suggesting that Gb3 is located in the long arm of chromosome 7D. The two AFLP markers cosegregating with Gb3 are valuable tools in developing molecular markers for marker-assisted selection of greenbug resistance in wheat breeding.

    Notes: The interaction of platinum (Pt) with electron irradiation-induced defects has been observed. Platinum in silicon increases irradiation-induced defects remarkably, especially the A center, and lowers the annealing temperature to 220 °C for the A center and to 140 °C for the divacancy and E center. The level Ea (0.23) in the Pt-doped silicon is the Pt(−/0) level, an acceptor like the A center. A method is suggested for activating the platinum in silicon with low-energy electron irradiation and subsequent thermal annealing and detecting it by deep level transient spectroscopy (DLTS).

    Notes: We have observed a redshift process of luminescence wavelength in an as-prepared porous silicon layer. Si—H bonds of a significant concentration are gradually replaced by Si—O bonds when porous silicon is exposed to air at room temperature, which coincides well with desorption of hydrogen from the silicon surface. SiH2 termination plays an important role in the emission process, and the surface passivation of the porous silicon layer is important to get effective and stable luminescence.
