    Notes: Summary The canine prostatic complex, including the prostatic urethra, the urethral openings of the prostatic gland ducts, the prostate gland proper and the ejaculatory ducts has been studied with the transmission and scanning electron microscopes. The urethral epithelium was found to be a modified transitional epithelium; it extended a short distance from the urethra into the orifices of the ducts where it gradually lost height. The columnar cells were replaced by cuboidal superficial cells in the terminal ducts of the gland. With increasing distance from the urethral openings of the ducts, the superficial cuboidal cells developed secretory activity and finally were indistinguish-able from regular prostatic secretory cells. The latter formed typical prostatic acini, consisting of secretory cells which were merocrine in nature, and flat lentilate basal cells. In addition to exocrine cells, three different types of presumptive endocrine cells occurred, predominantly in the periurethral ducts of the prostate gland. It has been concluded from this study that, firstly, fluid absorption and spermatophagy are the main functions of the epithelia of the ejaculatory ducts and the ampulla of the vas deferens. Secondly, it has been concluded that the different functions of the various structures of the prostatic complex can be related to their different embryological origins.

    Description / Table of Contents: Summary Fresh living cells of liver and kidney parenchyme from guinea-pig as well as kidney cell cultures from monkey were incubated with a defined complement standard. No influence on the total lytic activity could be observed. Likewise, with media, in which fresh cells were kept for several hours, no effects were obtained. The anticomplementary activity of whole kidney homogenates, as found byBeeson andRowley, cannot be considered a direct product of cells of the kidney parenchyme.
    Notes: Zusammenfassung Frische lebende Parenchymzellen von Niere und Leber vom Meerschweinchen sowie Affen-Nieren-Zellkulturen wurden mit definiertem Komplementstandard inkubiert. Eine Beeinflussung der gesamtlytischen Aktivität konnte dabei nicht festgestellt werden. Auch Nährmedien, in denen frische Zellen mehrere Stunden gehalten worden waren, ließen keinen Effekt erkennen. Die vonBeeson undRowley ermittelte antikomplementäre Wirkung von Nierengesamthomogenaten ist nicht als direktes Produkt der Nierenparenchymzelle aufzufassen.

    Description / Table of Contents: Summary In 76 patients with chronic bronchitis total complement (C′) activity and antibody titer (versus correspondent microorganisms cultured from sputum samples) were determined. 57 patients (= 75%) were found to have normal C′ titers (C′H50/ml), in 17 cases (= 22,4%) the C′ titers were elevated above and in 2 cases (= 2,6%) reduced under limiting values of control persons. The C′ titers tended to lower levels when antibody titers increased. It is supposed that continuous immune reactions cause the relative decrease of complement activity when antibody titers are increased.
    Notes: Zusammenfassung Bei insgesamt 76 Patienten mit chronischer Bronchitis wurden Komplement(C′)- und Antikörper(Ak)Titer (gegen die jeweiligen aus Sputumproben gezüchteten Keime) bestimmt. Die C′-Titer (C′H50/ml) lagen bei 57 Patienten (= 75%) im Normbereich, bei 17 Patienten (= 22,4%) oberhalb und bei 2 Patienten (= 2,6%) unterhalb der Grenzwerte bei Kontrollpersonen. Dabei tendierten bei höheren Ak-Titern die C′-Titer zu niedrigeren Werten. Es wird vermutet, daß kontinuierliche Immunreaktionen den relativen Abfall der C′-Titer bei gleichzeitig hohen Ak-Titern bedingen.

    Description / Table of Contents: Summary In 6 cases the complement (C′)-content was determined in serum, obtained by direct sampling from prerenal arterial and postrenal venous, as well as from other blood vessels. In no case different total C′-titers could be demonstrated in pre- and postrenal serum. Also the concentration of the individual classical 4 C′-components was found to be uniform. Hence, an anticompementary renal factor, as detected byBeeson andRowley in renal homogenates, appears to be non existent in renal vein blood.
    Notes: Zusammenfassung Bei sechs Probanden wurde der Komplement (C′)-Gehalt in Seren, die nach direkter Sondierung aus prärenalen arteriellen und postrenalen venösen sowie aus anderen Gefäßbereichen gewonnen worden waren, bestimmt. Dabei zeigten sich in keinem Fall im prä- und postrenalen Serum unterschiedliche Gesamt-C′-Titer. Auch die jeweiligen Titer der klassischen vier C′-Komponenten verhielten sich einheitlich. Ein antikomplementär wirkender renaler Faktor, wie ihnBeeson undRowley in Nierenhomogenaten feststellten, ist im Nierenvenenblut nicht nachzuweisen.

    Description / Table of Contents: Zusammenfassung. Das Ziel der chirurgischen Therapie von lokalisierten Weichgewebssarkomen ist die lokale Tumorkontrolle bei gleichzeitig bestmöglichem Funktionserhalt. Eine primäre und alleinige chirurgische Therapie ist dabei nur bei oberflächlichen, kleinen, gut differenzierten oder streng intracompartmental gelegenen Prozessen möglich. In allen anderen Situationen, und insbesondere bei Rezidivtumoren, ist der Einsatz multimodaler Behandlungsstrategien erforderlich. Vor allem bei lokal fortgeschrittenen Tumoren kann durch eine neoadjuvante Therapie eine Tumorrückbildung erreicht werden. Neben der systemischen Chemotherapie und der präoperativen Bestrahlung kann in dieser Situation auch durch die isolierte Extremitätenperfusion mit TNF und Melphalan eine verbesserte lokale Tumorkontrolle erreicht werden, um anschließend eine kurative Resektion extremitätenerhaltend zu ermöglichen. Der Wert einer systemischen adjuvanten Chemotherapie zur Verbesserung des Gesamtüberlebens der Patienten muß innerhalb von Studien weiter abgesichert werden. Im metastasierten Erkrankungsstadium ist das Hauptaugenmerk der Behandlung auf die Lebensqualität für den individuellen Patienten zu legen. Ist keine R0-Resektion des lokalen Tumors bei Extremitätenerhalt möglich, so kann durch multimodale Verfahren eine z. T. längerfristige Tumorkontrolle erreicht werden.
    Notes: Summary. The aim of surgical therapy for soft tissue sarcoma is local tumor control with the best possible functional result. Only small, superficial, well-differentiated or strictly intracompartmental lesions should be treated by surgery alone. In all other cases, especially for recurrent lesions, multimodality treatment strategies should be applied. For locally advanced lesions, neoadjuvant therapy can achieve tumor response. Aside from systemic chemotherapy and preoperative radiation therapy, isolated limb perfusion with tumor necrosis factor and melphalan can aid local control, and thus enable limb-sparing resection. The application of adjuvant systemic chemotherapy must be further investigated in prospective trials before a general recommendation can be given. If the patient has distant metastases, decisions regarding treatment of the local lesion must take into account quality-of-life aspects. Should complete resection not be possible, multimodality strategies may be able to control the tumor for a longer period.

    Notes: Summary The capacity of Leydig cells for regeneration was investigated in 12 patients with prostatic carcinoma, who underwent subcapsular orchidectomy, and in rats after testicular necrosis produced by cadmium chloride. In rats, reappearance of Leydig cells originating from the tunica albuginea could be demonstrated by histology. Testosterone concentrations increased parallel to regeneration of Leydig cells, while LH concentrations declined. In contrast to these findings, no rise of testosterone concentrations could be observed in patients up to 8 months after subcapsular orchidectomy. Human Leydig cells seem to have no capacity for regeneration, or endocrine function, despite the fact that some of these cells, which are present morphologically in the tunica albuginea or spermatic cord, remained.

    Notes: Zusammenfassung Die intermittierende Androgendeprivation (IAD) stellt ein neues therapeutisches Konzept in der palliativen Behandlung des Prostatakarzinoms dar, das experimentell gut begründet ist. Die bisherigen vorliegenden klinischen Pilotstudien lassen eine bessere Lebensqualität unter IAD vermuten ohne negative Effekte auf die Überlebensrate. Die aktuelle Datenlage erlaubt keine Aussage über einen Einfluß der IAD auf das progressionsfreie Intervall. National und international sind verschiedene prospektive randomisierte Studien initiiert, die den Stellenwert der IAD prüfen. Mit ersten Ergebnissen ist nicht vor zwei Jahren zu rechnen. Eine Behandlung mit IAD sollte deshalb nur unter Studienbedingungen erfolgen. Zu einer breiten Beteiligung aller onkologisch interessierten Urologen an den AUO-Studien wird aufgefordert.

    Notes: Abstract The aim of the present paper is to report on the frequency of pyelocalyceal diverticula and the relation to other renal abnormalities in 5000 routine IVPs. Pyelocalyceal diverticula are mostly occasional findings and they usually cause symptoms when complicated by inflammation or stones. These complications will characterize the symptoms. There is an indication for surgical treatment when the diverticula are complicated by stones or inflammation which fail to respond to simple antibiotic treatment. According to our experience, the removal of the diverticulum bearing renal segment is a safe procedure with good postoperative results.
