For the closed treatment of an intraarticular fracture of the heel bone it is essential to know the 3D shape of the bone, the various types of fractures and to get skilled in reduction under an image intensifier. In our hospital we have made a comparison of 34 fractures treated with a plate and 94 treated with screws. The evaluation was made by the scores(More)
We describe a new cation-exchange fluorometry procedure for separation and measurement of three 5-hydroxyindole metabolites of tryptophan in blood. The metabolites are detected and measured via the fluorescence emitted in the visible region when the separated metabolite is added to a hydrochloric acid-ascorbic acid mixture. The assay requires only 30 mm and(More)
Authors give historical review of different classifications in the cases of distal radial fractures. They give analysis on advantage and disadvantage of three different classifications, based on 633 cases, according to the practical applicability, to the expected outcome and to the way of treatment. According to the analysis the Older classification gives(More)
Although meat consumption plays a significant role for individual and public health, there is only little empirical research on the motives of meat consumption informed by health psychology and hardly any on socio-political commitments concerning general meat production taking on a public health perspective. To fill this gap, a questionnaire study was(More)
In the conservative treatment of distal radial fractures the main problem is redislocation due to instability. We evaluated the three classification methods most often used to find out how well the different groups correspond to instability and severity of fractures-thus what their prognostic value is in the probable recovery time. Based on an analysis of(More)
A rapid, sensitive and selective analytical procedure for phencyclidine and one of its metabolites in urine has bee developed. Three techniques have been studied for extraction of the drug from the biological matrix: (a) reversed-phase XAD resin, (b) charcoal absorption, and (c) solvent extraction using chloroform. Temperature-programmed gas chromatography(More)
