    Description / Table of Contents: Zusammenfassung Mit den bisher üblichen Färbemethoden war es kaum möglich, sicher zwischen frühen ischämischen Herzmuskelschäden, autolytischen Veränderungen and auch intaktem Myocard ohne Kernanschnitt zu unterscheiden. 1986 wurde erstmals eine immunhistochemische Methode vorgestellt, mit der C5b-9-Komplement-Komplex als Nekrosemarker am Kryostatschnitt dargestellt wurde. In Fortentwicklung dieses Verfahrens wird eine Technik zur Anwendung am Routine-Paraffinschnitt beschrieben: Mit dem C5b-9-Komplement-Komplex gelingt es insbesondere, disseminierte Einzel- und Gruppenfasernekrosen des Myocards exakt and autolyseunempfindlich darzustellen. Die Anwendung dieser Methode am Paraffinschnitt eröffnet den Weg zur Routinediagnostik sehr früher ischämischer Herzmuskelschädigungen selbst in Fallen von “Sekundenherztod”.
    Notes: Summary With conventional staining techniques it was nearly impossible to differentiate with certainty between early ischemic myocardial lesions, autolytic changes and intact myocardium without a nuclear section. In 1986 it was introduced an immunohistochemical method, which presented C5b-9 Complement Complex as a necrosis marker in cryostat sections. Our further development of this process has resulted in a technique for application on routine paraffin sections: C5b-9 Complement Complex is particularly well-suited for the exact and autolytically insensitive presentation of disseminated necroses of fiber bundels and single fibers of myocardium. The application of the technique on paraffin sections will lead to the use of the same in forensic medicine routine diagnostics of early ischemic myocardial lesions, even in cases of “sudden” cardiac death.

    Notes: Abstract Glomerular filtration rate (GFR) and renal uptake of dimercaptosuccinic acid (DMSA) were measured in 31 patients with progressive chronic nephropathy before and immediately after the start of treatment with angiotensin converting enzyme (ACE) inhibitor in order to control adverse effects on kidney function. Scintigrams of the kidneys showed an unaltered distribution of DMSA during treatment. GFR estimated by51Cr-EDTA plasma clearance fell by 14% (P 〈 0.01), but renal uptake of99mTc-DMSA increased by 10% (P 〈 0.01). It is concluded that DMSA in chronic renal failure is mainly taken up by the tubular cells from the peritubular capillaries since the uptake was unaffected by the acute decrease in GFR.
