A variety of health effects have been attributed to 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD), but little information is available on the course of a verified high-level TCDD intoxication. In this paper we describe two cases of heavy intoxication with TCDD and present a 2-year follow-up including clinical, biochemical, hematologic, endocrine, and(More)
Acute myeloid leukaemia (AML) is a life-threatening haematopoietic disease that is characterized by clonal growth and the accumulation of myelopoietic progenitor cells. Although AML cells only have a limited potential to undergo differentiation and maturation, each AML clone is organized in a hierarchical manner similar to normal haematopoiesis. Recent data(More)
In the murine system, a number of cytokines (including interleukin-3 [IL-3], IL-4, and stem cell factor [SCF]) promote the growth of mast cells (MCs). However, so far little is known about factors controlling differentiation of human MCs. Recent data suggest that human MCs express receptors (R) for SCF. The aim of the present study was to investigate(More)
Although tonsil surgery is one of the most frequent otorhinolaryngological procedures, not many population-based regional or country-wide studies are published on the incidence of postoperative bleeding and its risk factors. 2,216 patients underwent tonsil surgery in 2012 in Thuringia, a federal state in Germany. Most frequent indications were recurrent(More)
To prospectively assess the role of MDR1 gene expression in patients with de novo acute myeloid leukemia (AML), levels of MDR1 RNA in blast cells were determined at diagnosis and correlated with treatment outcome in 63 patients. MDR1 RNA levels were negative in 29% and positive in 71% of the patients. The complete remission rate in response to induction(More)
To determine the clinical significance of the lung resistance protein (LRP) in acute myeloid leukemia (AML), we have studied LRP expression of leukemic blasts and its association with clinical outcome in patients with de novo AML. LRP expression of leukemic blasts was determined by immunocytochemistry by means of monoclonal antibody LRP-56. LRP expression(More)
Autonomous release of hematopoietic growth factors may play a crucial role in the pathogenesis of certain hematological malignancies. Because of its cytokine synthesis-inhibiting action, interleukin 10 (IL-10) could be a potentially useful molecule to affect leukemic cell growth in such disorders. Chronic myelomonocytic leukemia (CMML) cells spontaneously(More)
The in vivo effect of recombinant human interleukin-3 (rhIL-3) on peripheral blood (PB) levels of hematopoietic progenitor cells was studied in nonhuman primates. Subcutaneous administration of 33 micrograms/kg/d of rhIL-3 for 11 to 14 days to rhesus monkeys slightly raised leukocyte counts (twofold) and substantially expanded the pool of circulating stem(More)
 Twenty-two patients with refractory or relapsed AML were treated with FLAG [25 mg/m2 fludarabine daily (days 1–5), 2 g/m2 daily Ara-C (days 1–5) and 400 μg/m2 daily G-CSF (day -1 till the absolute neutrophil count was >500/μl)]. Median age was 46 years (range 24–63). Eight patients had leukemia which was primarily refractory to conventional regimens, six(More)
Karyotypic studies in patients with monoclonal gammopathy of undetermined significance (MGUS) have been hampered by a low percentage of bone marrow plasma cells (BMPC), which are predominantly nonproliferating. By combining cytomorphology and interphase fluorescence in situ hybridization (FISH) we investigated whether or not chromosomal abnormalities occur(More)
