Mit den Tyrosinkinase-Inhibitoren Sunitinib und Sorafenib stehen 2 effektive Angiogenese-Inhibitoren zur Therapie des metastasierten Nierenzellkarzinoms zur Verfügung. Bei der notwendigen chronischen Verwendung dieser, einer neuen Substanzklasse zuzuordnenden Medikamente treten Nebenwirkungen auf, die unter Umständen eine langfristige Therapie erschweren(More)
The analytic and diagnostic validity of the determination of carboxyhaemoglobin and carbon monoxide in smokers and non-smokers was investigated. Both methods are of high analytic and diagnostic validity. Precision and accuracy fullfil the essential requirements. Comparison of the methods shows good correlation (= 0.97) and linear regression (y = 51.5 X(More)
Healthy volunteers smoked 21 to 26 cigarettes containing different amounts of condensate (tar) and nicotine for 16 wk. Enzymes and metabolites of erythrocyte metabolism were not influenced, with the exception of a slight inhibition of delta-aminolevulinic acid dehydratase. Hematological parameters were normal except the white blood count, which was elevated(More)
Carbonyl reductase (EC 1.1.1.184) is one of several monomeric, NADPH-dependent oxidoreductases having wide specificity for carbonyl compounds that are generally referred to as the aldoketoreductases. The grouping of the enzyme into the family has been proposed on the basis of functional similarities and in the absence of structural data. Here, we describe(More)
Enchondromas are said to be extremely rare precursors of secondary chondrosarcomas. Peripheral enchondromas of the hand and foot may be considered as benign, even when the histomorphological study reveals pleomorphic features with atypical nuclei. Our case deals with a 56 year old woman who had an enchondroma of the first metatarsal. Its distinct(More)
Sunitinib and Sorafenib are both effective angiogenetic inhibitors for the treatment of renal cell carcinoma. With these drugs of a new class of chronic therapy is performed. During chronic treatment, the inherent side effects may necessitate stopping the application of these drugs thus preventing the required effective therapy. Most of the effects can be(More)
Fibrinogen Milano VII is a hereditary fibrinogen variant detected in a woman with no clinical symptoms of bleeding or thrombosis. Thrombin and reptilase clotting times were prolonged in six family members from three generations. Release of fibrinopeptides A and B was normal. Fibrin polymerization was strongly delayed both in the presence and in the absence(More)
We describe an ultrasensitive and reliable method for determining vanadium in human serum by electrothermal atomic absorption spectrometry. After lyophilization, the serum is digested in acid at high pressure, and the digests are evaporated to a small volume. Vanadium in the digests is complexed with cupferron, extracted, and dried. The residue is(More)
We report our findings in a patient with coronary heart disease who received an intravenous albumin solution that contained a significant level of vanadium on the first day after elective primary coronary revascularization. Six patients who underwent similar surgical procedures without albumin infusion were taken as a control group. After administration of(More)
An abnormal fibrinogen was discovered in a clinically asymptomatic woman from Italy. Routine coagulation studies revealed prolonged thrombin and reptilase clotting times and a discrepancy between the plasma fibrinogen levels determined by the clotting assay and electroimmunoassay. Release of fibrinopeptides A and B from fibrinogen Milano V by thrombin was(More)
