Proliferation indices and mean number of silver-stained nucleolar organizer region-associated proteins (Ag-NORs) are compared in 65 brain tumors, including 34 gliomas, 8 meningiomas, 17 metastatic tumors, and 6 other tumors. Immunocytochemical investigations include labeling with the monoclonal antibody Ki-67 which identifies the whole growth fraction, and(More)
Metallothioneins (MTs) are ubiquitous low-molecular-weight proteins with a high affinity for heavy metal ions such as zinc, copper and cadmium. MT over-expression has been associated with resistance against anticancer drugs. In the present study we investigated 86 cases (45 cases of tumour category pT1 and 41 of category pT2) of routinely fixed and(More)
The aim of the present study was to define prognosis and life expectancy in patients with chronic liver disease of different etiologies and to relate them to an age- and sex-matched normal population. After a follow-up of 15 years, life expectancy of 620 patients with chronic liver disease was retrospectively calculated and compared with an age- and(More)
Argyrophilic nucleolar organizer region associated proteins (AgNORs) are known to reflect cellular and nucleolar activity. Due to a novel staining procedure, which substantially improves visualisation of AgNORs on formalin-fixed and paraffin-embedded material, AgNORs can be reliably demonstrated as true substructures of the nucleoli. The aim of the present(More)
Surgical treatment of colorectal cancer (CRC) should be aimed primarily at achieving a combination of surgical-oncologic radicalness and the highest possible quality of life. In recent years, surgical therapy for T1 CRC has tended toward less radical interventions. The question regarding changes in survival and recurrence rates still is unanswered. A(More)
We previously applied intravital lectin perfusion in mouse models to elucidate mechanisms underlying vascular permeability. The present work transfers this technique to human models, analysing vascular permeability in macro- and microvessels. Human vascular endothelial surface carbohydrate biochemistry differs significantly from its murine counterpart,(More)
The prognostic value of clinicopathologic data and tumor cell morphometry was assessed in 49 consecutive patients with advanced epithelial ovarian carcinoma (Stage III-IV as defined by the International Federation of Gynaecologists and Obstetricians [FIGO]). Single-variant analysis proved that nuclear area at the 10th, 50th, and 90th percentiles and nuclear(More)
Several analyses of hernia registries have demonstrated that patients older than 65 years have significantly higher perioperative complication rates compared with patients up to the age of 65. To date, no special analyses of endoscopic/laparoscopic inguinal hernia surgery or of the relevant additional influence factors have been carried out. Besides, there(More)
GRUNDLAGEN: 90 % aller Fälle mit Intussuszeption (ITSS) im Erwachsenenalter werden sekundär durch andere pathologische Veränderungen verursacht, welche insbesondere im Kolon häufig maligne sind. Die klinischen Symptome sind oft unspezifisch mit chronischem Verlauf, akute Fälle mit der Notwendigkeit einer Notfall-Operation sind jedoch nicht selten. In diesen(More)
Metallothioneins (MTs), a set of ubiquitous low-molecular-weight proteins essential for the protection of cells against heavy metal ion toxicity, were demonstrated immunohistochemically using a monoclonal antibody (E9) against a conserved epitope of I and II isoforms in a series of 109 colorectal adenocarcinomas. In a semiquantitative analysis strong MT(More)
