    Streszczenie angielskie: Various hormones can influence the expression of interleukin-6 (IL-6) and oestrogens are the most extensively studied. There is, however, controversy about the nature of the IL-6 secreted by human cells and its regulation by 17á-oestradiol. The aim of this work was to clarify whether oestrogen deprivation after menopause may contribute to an enhanced IL-6 production by peripheral blood mononuclear cells (PBMC) in postmenopausal women. Twenty-two healthy postmenopausal women, age range 45-63 years with clinical symptoms of oestrogen deficiency were enrolled in the study. The control group consisted of 16 healthy young women, age range 22-31 years, with regular menses and who were not taking oral contraceptives. Levels of IL-6 in the sera and PBMC culture supernatants were measured by the biological B9 cell-proliferation assay and expression of the IL-6 gene in non-stiulated PBMC was detected by RT-PCR. The effect of 17á-oestradiol on spontaneous IL-6 production by the PBMC of postmenopausal women was also studied in vitro and in vivo. Seventeen out of the twenty-two postmenopausal women were given hormonal replacement therapy of 50 ćg 17á-oestradiol/day transdermally and the spontaneous production of IL-6 by the PBMC was analysed after 6 and 12 months of treatment. The postmenopausal women had significantly higher serum levels of IL-6 than the young controls. The spontaneous production of IL-6 by non-stimulated PBMC into the culture supernatants was also significantly higher in the postmenopausal women compared with the young...

    Streszczenie angielskie: Bacground. Recombinant human erythropoietin (rHuEpo) may affect the human immune system. The aim of the study was to examine changes in CD4+ and CD8+ T-cell subpopulations, the expression of the inhibitory molecule, CD152 on T lymphocytes and the levels of interleukins (IL), 2, 6, 10, 12 and tumour necrosis factor ŕ )TNFŕ) in primary glomerulonephritis chronic haemodialysis (HD) patients before and under rHuEpo treatment. Methods. Expression of T-cell surface molecules was measured in 14 HD patients ex vivo by flow cytometry of lymphocytes sampled from peripheral blood and in viutro using whole blood cell cultures stimulated either with phytohaemagglutinin (PHA) or with physiological as well as non-physiological does or rHuEpo. The concenrations of the cytokines were measured in the supernatans from non-or PHA-stimulated cultures using bioassays (IL2, IL6, TNFŕ) or ELISA test (IL10, IL12). Results. Compared with findings before the start of rHuEpotherapy the CD4+/CD8+ ratio increased after 1 year of follow-up, whereas the percentage of CD152+ peripheral blood lymphocytes decreased. The increase of the CD4+/CD8+ rtio was dependent on a decrease of the percentage of CD8+ cells. The decrease of CD152+ population affected mainly CD8+ CD152+ cells. All these effects became apparent after 6 months of rHuEpo treatment. In vitro stimulation of whole blood cultures revealed that the addition of PHA up-regulated the percentage of CD152+ lymphocytes, while physiological concentrations of rHuEpo decreased the percentage of CD8+ 152+ T cells...
