    Neither major depression nor glucocorticoid treatment affects the cellular integrity of the human hippocampus (2001)

    Notes: In major depression, decreased hippocampal volume has been attributed to hypercortisolemia, a frequent sign of the disorder, because in animals an excess of corticosteroids has led to dendritic atrophy, astrogliosis and loss of neurons in this brain region. The present study is the first to investigate the structural integrity of the human hippocampus in major depression and following glucocorticoid treatment. Post-mortem hippocampal tissue from 15 patients who had had major depression or bipolar affective disorder, 10 patients who had been treated with glucocorticoids and 16 controls was assessed using haematoxylin-eosin, Nissl and Bodian staining. The patterns of reactive astrogliosis (glial fibrillary acidic protein, GFAP), synaptic density (synaptophysin), synaptic reorganization (growth-associated protein B-50) and early signs of Alzheimer's disease (Alz-50) were examined immunocytochemically. Multivariate analysis, with the patients' age, tissue fixation time and postmortem delay as covariates, was performed. There was no evidence of neuronal cell loss or other major morphological alterations in any of the groups, nor was there a significant change in the distribution pattern of synaptophysin or Alz-50. Changes in B-50 and GFAP staining were observed in the steroid-treated and depressed patients in areas CA1 and CA2 only. The human hippocampus in major depression and after glucocorticoid treatment does not reveal any major morphological changes or signs of neuronal cell death, but does show subtle alterations in B-50 and GFAP expression in selected parts of the pyramidal cell layer.

    An attempt to estimate the predatory pressure exerted by the lesser weever, Trachinus vipera Cuvier, in the southern North Sea (1989)
    Oxford, UK : Blackwell Publishing Ltd
    Journal of fish biology 34 (1989), S. 0

    Topics: Biology
    Notes: In order to evaluate the impact of the lesser weever on the ecosystem of the southern North Sea, geographical distribution, density, growth, production and food requirements have been estimated. High densities were found on and around the Brown Ridge, an area with high tidal current velocities, medium grain-size of the sediment and a poor benthic fauna. Growth is restricted to the months of June October. During the winter cessation of growth a considerable loss of weight (about 20%) takes place. Mortality has been estimated by using the average size frequency distribution of all catches made from 1972 to 1984. The resulting convex type of survival curve indicates a high survival rate of the II to IV-group fishes. The production (estimated with Allen's graphical method) of a population of 100 individuals including all age groups (0-VI) amounts to 123.7 g AFDW-year‘. In areas with highest densities, consequently, production amounts to 0.018–0.078 g AFDW-m2 -year-1. With an assumed transfer efficiency of 10% through the year, food requirements amounts to 0.18–0.78 g AFDW-m 2 -year -1. Since the lesser weever feeds mainly on fish (85.6%), almost exclusively on gobies (Pomatoschistus sp.), and with an assumed transfer efficiency of approximately 10%, the indirect predatory pressure exerted by it may amount to 1.6 6.7g AFDW-m 2.year -1. A possible feeding by gobies on pelagic organisms (calanoids, mysids) is discussed.

    Description / Table of Contents: Zusammenfassung 190 an der Chirurgischen Universitätsklinik Köln durch Anastomosennachresektion und Vagotomie behandelte Kranke mit peptischen Rezidivulcera wiesen eine Komplikationsrate von 18,9% and eine Operationsletalität von 8,4% auf. Infolge besonderer Situationen wurde bei 27 Patienten mit zum Teil großen, penetrierenden Geschwüren auf die Nachresektion verzichtet and lediglich eine selektive Vagotomie vorgenommen. Sämtliche belassenen Ulcera heilten innerhalb von 2 Wochen ab und die Salzsäureproduktion wurde für die BAO um 78,3%, die PAO um 66,2% reduziert. Ernsthafte Komplikationen, Todesfälle oder erneute Rezidive warden 6 Monate bis 5 Jahre postoperativ nicht beobachtet.
    Notes: Summary 190 patients suffering from recurrent ulcers after gastrectomy were treated in the surgical department of the University of Cologne by vagotomy and resection of the anastomosis; complications occurred in 18.9% and lethality was 8.4%. Due to particular circumstances, 27 patients, some of whom had large, penetrating ulcers, received only selective vagotomy without resection of the anastomosis. All ulcers healed within 2 weeks and the gastric acid output was reduced by 78.3% for BAO and 66.2% for PAO. There were no severe complications and no fatalities. Over a follow-up period of 6 months to 5 years no further recurrence of ulcers has been seen.

    Description / Table of Contents: Zusammenfassung Bei 195 mit Nachresektion und trunkulärer Vagotomie behandelten Patienten betrug die Komplikationsrate 19,4% und die Op.-Letalität 8,4%. 44 nur mit trunkulärer bzw. selektiver Vagotomie behandelte Kranke zeigten eine Komplikationsrate von 9,2% und bisher keine Letalität. Erneute Rezidive wurden nach Nachresektion und trunkulärer Vagotomie in 4,2%, nach trunkulärer Vagotomie allein in 16,6% und nach sorgfältiger selektiver Vagotomie bisher nicht beobachtet. Die höhere Rezidivrate nach trunkulärer Vagotomie wird auf Variationen im Verlauf der Vagusstämme zurückgeführt und die selektive Vagotomie als risikoarme und erfolgssichere Methode empfohlen.
    Notes: Summary In 195 patients treated by regastrectomy and truncular vagotomy a complication rate of 19.4 percent and a mortality of 8.4 percent were observed. In 44 patients treated by truncular or selective vagotomy only, the complication rate is 9.2 percent and mortality so far nil. Further recurrences were recorded in 4.2 percent after regastrectomy and truncular vagotomy and in 16.6 percent after truncular vagotomy only. No recurrence has yet been determined after careful selective vagotomy. The higher recurrence rate is attributed to variations in the continuation of the vagus trunks. Selective vagotomy is recommended as a low-risks successful method.

    Description / Table of Contents: Zusammenfassung. An kryokonservierten humanen Ductus-cysticus-Präparaten wurden Dislokationsversuche durchgeführt, um die Sicherheit verschiedener laparoskopischer Clips zu prüfen. Der Ductus cysticus wurde dabei fixiert und auf die quer plazierten Clips eine axiale Zugkraft ausgeübt und gemessen. Die registrierten Medianwerte lagen für die sechs getesteten Clips zwischen 4,1 N und 11,2 N und unterschieden sich hochsignifikant (p 〈 0,001, Kruskal-Wallis-ANOVA). Dabei waren die beiden resorbierbaren Clips (Polydioxanone, Polyglykonat/Polyglykolsäure) deutlich den vier Titan-Clips überlegen (p 〈 0,005, Wilcoxon-Test). Neben dem Vorteil der völligen Biodegradierbarkeit empfiehlt sich daher der Einsatz resorbierbarer Clips, da sie einen noch sichereren Gewebehalt als die Titan-Clips gewährleisten.
    Notes: Summary. Kryopreserved specimens of cystic ducts were used for displacement tests to investigate the security of different laparoscopic clips. The cystic duct was fixed, and the transverse placed clips were distracted in axial direction and the forces registered. The median values of the six investigated clips ranged between 4.1 N and 11.2 N with a highly significant difference (P 〈 0.001, Kruskal-Wallis ANOVA). In detail, both resorbable clips (polydioxanone, polyglyconate/polyglycol acetate) were superior to the four titanium clips (P 〈 0.005, Wilcoxon test). In addition to the advantage of complete biodegradibility, these data favour the use of absorbable clips because holding force is better than that of titanium clips.
