A case of attempted suicide by ingestion of 4.8 g As2O3 (more than 20 times the estimated lethal dose) is reported. Absorption of arsenic caused elevated urinary levels over 5 days BAL treatment was started within three hours after arsenic ingestion. The patient did not develop any signs of polyneuropathy or other clinical changes.
We describe an enzyme-immunoassay for the determination of factor VIII antigen. After representation of the isolation of proteins the enzyme-immunoassay is presented. The principle of the method is the following: Test plasma is mixed with rabbit antibody in excess and incubated at 37 degrees C. The incubation mixture is added to polystyrene tubes, which are(More)
Nowadays progress in medicine keeps human beings alive more frequently in hopeless and depressing situations associated with physical discomfort and pain for a long time. This situation, which is at least partly caused by medical treatment, should be generally reviewed, in particular with respect to the treatment of cancer patients. This principles of(More)
We describe an enzyme-immunoassay for the determination of factor VIII related antigen. The principle of the method is the following: Test plasma is mixed with rabbit antibodies against human factor VIII in excess and incubated at 37 degrees C. The incubation mixture is added to polystyrene tubes coated with human factor VIII. The rabbit antibody is(More)
Clonogenic assays have attracted most attention in the field of chemosensitivity testing procedures. For many practical reasons and theoretical considerations detailed in this paper the human tumour stem cell assay (HTSCA) has proven most suitable for this purpose. The slightly modified method originally described by Hamburger and Salmon was used for(More)

This paper deals with the model based optimization of tubular reactors for the production of LDPE. Due to the high complexity, solving an optimization problem of an industrial application is not straightforward. Often researchers seek the shortest way to reach their final goal by going directly to the development of a high-complexity model and optimize this(More)
