Aims: The proteases PAI-1 and uPA play a major role in extracellular matrix degradation, which facilitates tumour progression. Tumour budding is a histomorphological expression of enhanced tumour cell migration.

Materials And Methods: To investigate their prognostic value for and correlation with colon cancer, a prospective study was performed.

Painful pink or magenta colored skin lesions characterized by a clear line of demarcation between the affected area and surrounding tissue appearing under therapy with coumarins may be a sign for evolving coumarin-necrosis. Immediate treatment with a protein C preparation in patients with protein C deficiency can prevent necrosis.

The medical diagnostics of 400 patients of an interdisciplinary environmental medical centre is presented. The basic diagnostics included a special environmental medical history using a questionnaire, physical examination, allergological examinations and human biomonitoring. The latter was carried out in order to quantify the internal exposure to environmental pollutants.

Twenty-one high-risk patients with primary stage II/III breast cancer were treated with high-dose chemotherapy comprising etoposide, ifosfamide, carboplatin and epirubicin (VIC-E). Tumor cells of epithelial origin were analyzed using the monoclonal antibodies CK2 (IgG1) and A45-B/B3 (IgG1) against cytokeratin (CK) components in bone marrow (BM) aspirates prior to chemotherapy, and in peripheral blood stem cell transplants (PBSCT). They were separated after the first (21/21 patients) and the second cycle (16/21 patients) of induction chemotherapy with VIP-E (etoposide, ifosfamide, cisplatin, epirubicin).

A polymerase chain reaction (PCR) assay was applied for the selective amplification of a characteristic sequence within a Salmonella-specific chromosomal fragment. A two-temperature PCR cycle enhanced both the speed and overall sensitivity of the amplification procedure. Twenty-one well-characterized Salmonella strains and a number of non-Salmonella strains were tested.

Brevibacterium epidermidis is a major component of the bacterial flora of certain skin surface biotopes, characterized by a comparatively high pH-value. The presence of Brevibacterium epidermidis seems to be linked to the production of malodour. Skin surface pH has been found to be a major factor of bacterial growth on the skin.

We typed 18 isolates of Legionella bozemanii obtained from clinical and environmental sources by pulsed-field gel electrophoresis. Each of the unrelated strains showed individual restriction patterns of the genomic DNA when either the SfiI or NotI restriction enzyme was used. One strain isolated from a patient with nosocomial legionellosis and two strains from the corresponding hospital water supply were indistinguishable, arguing for a transmission of L.

A nosocomial case of Legionellosis in a recently built hospital was the reason for an investigation and thermal disinfection of the complete warm water distribution system. Furthermore weak points in the tubing of the warm water system, which promoted the contamination of potable water, were eliminated as far as technically possible. A lasting reduction of the numbers of Legionella spp.

Legionella infections are getting increasingly important as causes of severe pneumonias or of acute respiratory insufficiency. Consumptive or immunosuppressive underlying diseases such as diabetes mellitus, cardiac insufficiency, alcohol-induced liver damage, malignant tumours or drug-induced immunosuppression after organ transplantation, are among the risk factors. Diagnosis is based on direct identification of the pathogen from body secretions by means of direct immunofluorescence.

A Legionella pneumophila strain (Jena-1) was isolated from a water sample collected from the hot water system of a scientific institution in Jena, Germany. Protein profile, ubiquinone and fatty acid content of the outer membrane were in accordance with those described for other Legionella pneumophila serogroups. DNA extracted from strain Jena-1 gave a positive amplification by using an L.

Porphyrin production by the haemin-independent Haemophilus parainfluenzae in the diagnostic porphyrin test, which determines the X-factor requirement in Haemophilus spp., was analysed quantitatively by applying modern high-performance liquid chromatographic (HPLC) methods. Ion-pair reversed-phase HPLC enabled the simultaneous separation of all porphyrin intermediates and their isomers of haem biosynthesis produced by the bacteria.

Epizootic examinations were made on 796 newborn piglets to test the consequences of the resection of a piglet's canine and lateral incisor teeth on its first day of life. As a comparative examination the resection was carried out with side-cutter pliers or with the teeth grinder PIGMATIC 110. A third group of piglets was not treated.

Ten patients from a rehabilitation center were admitted to hospital with serious respiratory infections within ten weeks. An outbreak of Legionnaire's disease was suspected based on the epidemic and atypical manifestation of pneumonia and could be proven microbiologically. Pulmonary and extrapulmonary complications included respiratory failure, lung abscess, transitory renal impairment in five patients and acute renal failure requiring dialysis in one, tetraparesis caused by peripheral neuropathy and acute psychosis.

A series of nosocomial Legionella infections in a rehabilitation center is reported. In a three months period a total of 10 pneumonias with 3 deaths occurred (8 patients, 1 companion, 1 staff member). Serologic analysis proved additional Legionella infections within the nursing staff.

Legionella pneumophila serogroup 1 (Lp1) strains isolated from patients and hot water supplies in different locations of Germany were subtyped using seven monoclonal antibodies (mabs) in the indirect immunofluorescence test (IFA) and in part, using a dot blot assay. Four of these mabs were produced in Dresden. Three mabs (mab 33G3, mab 32A12 and mab 144c2) were kindly supplied by J.

Besides other bacterial genera legionellae are a major causative agent of severe pneumonia. Therefore, it is essential to include legionnaires' disease into the diagnostics of pneumonia of unknown origin. The appreciable number of different species and serogroups of legionellaceae, most of them pathogenic for humans, render this task more difficult.

Ten days after starting military service in a police barracks a 25-year-old man developed left middle and lower lobe pneumonia which did not respond to ampicillin (8 g daily) and gentamycin (120 mg daily). Parenteral administration of doxycycline (100 mg daily) was equally ineffective. However, the fever fell on administration of cefotiam (4 g daily).
