Aqueous spleen extracts were purified using acetone precipitation, membrane filtration, affinity chromatography, and dialysis. These extracts were able to inhibit thymidine incorporation into lymphoid cells (MKT-CH and PHA-stimulated lymphocyte cultures). They did not influence non lymphoid tissue (melanoma cells Mel Ei 78 and Ehrlich ascites cells). The(More)
Staphylococcus epidermidis is a common cause of catheter-associated infections and septicemia in immunocompromised patients. To answer the question whether S. epidermidis skin isolates differ from isolates causing septicemic diseases, 51 strains obtained from blood cultures, 1 strain from shunt-associated meningitis, and 36 saprophytic isolates were(More)
Although they have potential, to date location-based information systems have not radically improved the way we interact with our surroundings. To study related issues, we developed a location-based reminder system, PlaceMail, and demonstrate its utility in supporting everyday tasks through a month-long field study. We identify current tools and practices(More)
175 patients with acute myeloid leukemia were treated between February 1980 and March 1985 with a TAD-induction therapy, three intensified consolidation cycles (COAP, COAP, AD), and a two-year mild maintenance therapy. The median age of the patients was 44 years, range 15-68 years. 62.3% of all patients attained complete remission and 13.7% partial(More)

This report outlines the morphologic classification of acute myeloid (AML: French-American-British FAB classification: M1) and lymphoid (ALL) leukemia by automatic image analysis and the correlation to immunologic and cytochemical classification. The investigation was carried out on Romanowsky-Giemsa stained bone marrow (n = 15) and blood smears (n = 10)(More)
