[Transforming growth factor beta, metalloproteinase 2 and its tissue inhibitor 2 in the serum from patients with early and late boreliosis].

Unlabelled: Boreliosis is an arthropod transmitted, bacterial infection, known for its complicated pathogenesis and prolonged course. Boreliosis can be divided into early, localized type, early generalized type as well as late type. Cytokines control homeostasis of the organism by transmitting signals between cells.

[Estimation of L-selectin expression on neutrophils and level of soluble L-selectin form in serum of patient with chronic myelogenic leukemia].

The aim of this study was the estimation of L-selectin expression on PMN and concentration of sL-selectin in patients serum with chronic myelogenic leukemia. The results indicate the increased expression of L-selectin on isolated neutrophils from peripheral blood of patients with chronic myelogenic leukemia. A concentration of sL-selectin was also increased in patients serum with chronic myelogenic leukemia.

[Estimation of level of soluble form PECAM-1, ICAM-2 and TNF-alpha, IL-18 in serum patients with chronic myelogenic leukemia].

The aim of this study was to estimate sPECAM-1, sICAM-2 and TNF-alpha and IL-18 concentrations in serum patients with chronic myelogenic leukemia. The results indicate of increased level sPECAM-1, sICAM-2 and TNF-alpha, IL-18 concentrations in serum patients with chronic myelogenic leukemia. Elevation levels of sPECAM-1 and sICAM-2 may lead to inhibit of making myelogenic leukemia cells infiltrations through the block of surface their receptors in patients with CML.

[Serum and cerebrospinal concentrations of sICAM-1 sICAM-2, sICAM-3 in neuroborrellosis and tick borne encephalitis--preliminary report].

Objective: The aim was to evaluate the concentrations of the soluble forms of ICAM-1, ICAM-2, ICAM-3 in the serum and cerebrospinal fluid (CSF) of patients with neuroborreliosis and thick borne encephalitis before and after therapy in comparison with the control group.

Material And Methods: We examined 30 patients, 10 in each group: neuroborreliosis-group I (NB), tick borne encephalitis--group II (TBE) and in the control group (group K). The diagnosis of neuroborreliosis and TBE based on the clinical features was confirmed by ELISA assays: FSME Virus/TBE Virus test (VIRION, Germany) for TBE and Borrelia IgM and IgG Recombinant (Biomedica Austria) for NB.

[Expression of L-selectin on the surface of neutrophils stimulated by TNF-alpha and level of sL-selectin in serum of patients with lung cancer].

The aim of the study was to estimate L-selectin expression on peripheral blood PMN stimulated by TNF-alpha and concentration of a soluble form of L-selectin in serum of patients with small cell and non-small cell lung cancer. The results showed an increased expression of L-selectin on PMN isolated from peripheral blood and an elevated concentration of sL-selectin in serum of patients with small cell and non-small cell lung cancer. An increased expression of these adhesion molecules may be the result of neutrophil activation by inflammatory cytokines.

[Effect of LFA-1 expression on neutrophils and serum level of soluble ICAM-1 in patients with chronic myelogenous leukemia].

The aim of this study was to estimation of LFA-1 expression on PMN and concentration of sICAM-1 in serum patients with chronic myelogenic leukemia. The results indicate on increased expression of LFA-1 on isolated neutrophils from peripheral blood of patients with chronic myelogenic leukemia. A concentration of sICAM was increased in serum patients with chronic myelogenic leukemia either.

[Effect of interleukin 15 on the PMN activity in Lyme borreliosis].

In the present study, the effect was examined of rhIL-15 on neutrophil (PMN) activity (locomotion, phagocytosis and NBT reduction) in patients with Lyme disease. We found an increase of all parameters after IL-15 stimulation. The sera from the patients contained increased level of IL-15 in relation to controls.

[Expression of adhesion molecules LFA-1 and L-selectin on PMN and level of soluble sE-selectin and sL-selectin in the serum of patients with small cell lung cancer].

The aim of this study was to estimate expression of adhesion molecules LFA-1 and L-selectin on PMN of peripheral blood, and level of soluble sE-selectin and sL-selectin in the serum of 16 patients with small cell lung cancer (SCLC) before treatment. We observed significantly higher expression of LFA-1 and L-selectin on PMN in comparison to healthy persons and higher level sE selectin and sL selectin in the serum of SCLC patients. Increasing of adhesion molecules expression on PMN can lead to damage of neoplasmatic cells and may be one of the reasons for create a new cancer sites as well.

[INF-gamma and GM-CSF concentrations in serum of patients with Lyme disease].

Lyme borreliosis is a disease caused by Borrelia burgdorferi spirochete. The purpose of this study was to INF-gamma and GM-CSF concentrations in patients with Lyme borreliosis before and after treatment. The analyzed group consisted of 60 patients diagnosed with tick Spirochetosis.

[The role of adhesion molecules in cancer].

Adhesion molecules are cell surface proteins responsible for normal structure and function of tissues and organs. The process of tumour growth often involves alterations in expression of adhesion molecules that may lead to destruction of tissue architecture and to metastasising. This study describes behaviour of some adhesion molecules (selectins, integrins, cadherins and CD44 isoforms) in different cancers.

Effect of IL-18 on IL-1beta and sIL-1RII production by human neutrophils.

In the present study we investigated the effect of interleukin 18 (IL-18) on the production of IL-1beta and soluble IL-1 receptor II (sIL-1RII) by human neutrophils. The results obtained indicate that recombinant human IL-18 (rhIL-18) induces IL-1beta and, to a lesser extent, sIL-1RII production by human neutrophil isolated from peripheral blood. However, this effect was less important than lipopolysaccharide (LPS) stimulation.
