    Notes: Abstract  Interleukin-6 (IL-6) has been shown to be an inducer of the acute-phase response (APR) and to be involved in the pathogenesis of several disease states, including graft-versus-host disease (GvHD) following allogeneic bone marrow transplantation (BMT). As blood cells of the monocyte lineage are known to be major producers of this cytokine, we wondered whether extreme peripheral leukopenia following total ablation of hematopoiesis could compromise IL-6 production during the first days after allogeneic or autologous BMT. In the absence of detectable circulating leukocytes we measured elevated IL-6 levels in six children having fever (≥38°  C) of presumed infectious origin with an average of 74±60 units/ml (range 19–309 units/ml). IL-6 levels in febrile children having a normal hematopoiesis (118±254 units/ml, range 17–1213 units/ml) were not significantly higher than those found in the febrile BMT group (p〉0.05). Moreover, there was a clear association between elevated IL-6 levels and the presence of fever. C-reactive protein (CRP) was also elevated (≥1 mg/dl), whereas tumor-necrosis factor alpha (TNF) was undetectable (〈1 pg/ml). Two transplanted patients without fever during the period of total aplasia had neither detectable CRP nor IL-6, thus demonstrating that the transplant procedure itself does not induce an APR. Our data obtained during maximal leukopenia following BMT show that a functional hematopoietic system is not necessary for regular production of IL-6, which is associated with fever. Cells of nonhematopoietic origin may contribute to this production.

    Variables influencing cadmium concentrations in hair of pre-school children living in different areas of the Federal Republic of Germany (1988)

    Notes: Summary The influence of several factors on cadmium (Cd) concentrations in the hair of 474 pre-school children was examined. The study was performed in an industrial (Duisburg) and rural area (Westfalen) of the (FRG). Season, sex, hair color, and place of residence were found to be the main factors influencing Cd levels in hair. Concentrations of Cd in samples obtained during summer were on the average nearly twice as high as those sampled during winter (geometric means: 116.1 vs. 63.7ng/g). Boys had more Cd in their hair than girls (111.5 vs.74.0 ng/g). Cd levels in hair decreased from red to blond, to brown, and black hair. Children living in Duisburg had more Cd in their hair than those from rural areas (103.9 vs.77.Ong/g). Cd content in hair was inversely related to age.

    Hair zinc of young children from rural and urban areas in North Rhine-Westphalia, Federal Republic of Germany (1988)

    Notes: Abstract Hair zinc levels were estimated by atomic absorption spectrophotometry in 474 children, aged 3–7 years, from 11 kindergartens in a highly industrialized and polluted area (Duisburg) and 8 kindergartens in a rural area of North Rhine-Westphalia. The mean hair zinc level amounted to 118 μg/g, increasing between the 4th and 7th year of life. At all ages the values from the urban toddlers were lower than from rural toddlers, and in both regions they were higher in winter than in summer. Children with frequent upper respiratory tract infections (〉6 infections/year) showed significantly lower zinc hair values, independent of their age. Low hair zinc values (below 70 μg/g) were frequently found, raising the question as to whether this is a normal, age-related phenomenon, or whether it indicates a suboptimal zinc status of young children from North Rhine-Westphalia.
