    Description / Table of Contents: Zusammenfassung Zerebrale Perfusionsbilder wurden bei Patienten mit Halsschlagaderverschluß untersucht. Dazu wurde eine Infusion mit Krypton 81m in die A. carotis comm., A. carotis int. und in die A. vertebralis vorgenommen und dann computergesteuerte Einzelphotonenemissionstomogramme angefertigt. Analysiert wurde, welchen Beitrag der Gefäßkranz an der Hirnbasis und die Anastomosen der Großhirnrinde leisten, um eine angemessene Blutversorgung des betroffenen Gebietes aufrechtzuerhalten. Man kam zu dem Schluß, daß das zerebrale Perfusionsbild in der Abschätzung von Nebenkreisläufen der Angiographie überlegen ist. Im Fall eines Halsschlagaderverschlusses ist der Gefäßkranz an der Hirnbasis von Bedeutung, einen Infarkt im Gebiet der perforierenden Arterien zu verhüten, während die Großhirnrinde vorwiegend über die Anastomosen der weichen Hirnhaut mit Blut versorgt wird, was die Hauptrolle der Anastomosen der weichen Hirnhaut beweist.
    Notes: Summary Cerebral perfusion images were investigated in patients with carotid artery occlusion, using single photon emission computed tomography with the infusion of krypton-81m into the internal, common carotid and vertebral arteries. The contribution of the circle of Willis and cerebral cortical anastomoses to the maintenance of adequate blood supply into the involved hemisphere was analysed. It was concluded that the cerebral perfusion image is superior to angiography in evaluating collateral circulation, and in the case of carotid occlusion, the circle of Willis is important in preventing infarction in the territory of the perforating arteries, while the cerebral cortex mainly receives its blood supply through the cortical leptomeningeal anastomoses, illustrating the major role of the leptomeningeal anastomosis as a collateral channel.

    Notes: Summary The authors describe a catheter for multiartery studies in middle aged patients of relatively small stature. Experience in more than a thousand cases proved its special usefulness in selecting the left common carotid artery with tortuous aortic arch.

    Notes: Summary We assessed the origin of peripheral blood cells and bone marrow cells of 92 samples obtained from 19 patients after allo BMT by two-step polymerase chain reaction (PCR) amplification of MCT118, one of the variable number of tandem repeat regions (VNTR) which has a different length in 19 of 32 sibling pairs examined, that can detect the DNA pattern of a minor cell population of only 1% without using radioisotopes. Mixed chimerism (MC) was detected in the hematopoietic cells of four patients. Two patients who showed progressive MC developed relapse of leukemia 3 months and 4 months after the detection of MC, and two patients died with bone marrow hypoplasia 61 days and 7 months after BMT. These data suggest the clinical importance of analyzing the correlation of MC and clinical complications after BMT by this method, which can be used to monitor MC in about two thirds of allo BMT patients with an adequate sensitivity.

    Notes: Summary Disseminated fungal infection not infrequently complicates the course of allogeneic bone marrow transplantation (allo BMT) in severely immunocompromised patients, and the prognosis of BMT patients who develop systemic fungal infection is very poor. We describe a patient who developed disseminatedCandida albicans infection with liver abscess after the first allo BMT for acute myelogenous leukemia (FAB M2). The infection was successfully eradicated by the administration of miconazole and amphotericin B. However, 1 year after the first allo BMT, the patient suffered a relapse of acute myelogenous leukemia with fungal liver abscess. A second allo BMT, accelerating granulocyte recovery by recombinant human granulocyte colony-stimulating factor (rhG-CSF), was successfully performed and the fungal liver abscess resolved with a combination therapy of fluconazole and amphotericin B. The patient is alive and free of both leukemia and fungal disease more than 37 months after the first allo BMT and 25 months after the second allo BMT.
