UNLABELLED The causes of osteosarcoma (OS) and effector mechanisms of the immune response against OS and other neoplastic diseases remain unknown. According to current knowledge, the major role is attributed to cytotoxic T lymphocytes, NK, NKT and Tăä lymphocytes, which are engaged directly in the destruction of the tumour cells. Helper T lymphocytes (CD4+)(More)
OBJECTIVE The purpose of the study was to compare concentrations of inflammatory and Th1/Th2 cytokines in serum obtained from women with preeclampsia or severe pregnancy hypertension versus normotensive controls. MATERIAL AND METHODS The study group consisted of 34 pregnant women with hypertension over 140/90mmHg and proteinuria over 0.3 g/day or severe(More)
The important aspect of sulforaphane (SFN) chemopreventive activity is its ability to induce cell growth inhibition and apoptosis. In this study, the effect of SFN on lymphoblastoid cells derived from people carrying four different germ-line mutations in BRCA1 gene was tested and compared to the effect of SFN on wild-type cells. The mutations studied were(More)
Many studies in vitro and in vivo have shown immunomodulating and antiviral activities of inosine pranobex. The object of this research was to examine the potential beneficial effects of inosine pranobex (Groprinosin) on immune system in children with cellular immunodeficiency as a prophylaxis of recurrent infections, mainly of viral origin. 50 mg/kg(More)
BACKGROUND Osteosarcoma (OS) is the most frequent primary malignant bone tumour, mainly affecting children in the first and second decade of life. Causes of the disease are still unknown and reaction of the immune system on its development is very individual. Particular emphasis must be placed on the role of cytokines in the immunoregulatory and(More)
UNLABELLED Typical cells of specific immunity are lymphocytes. T cells may specifically recognize antigens using T Cell Receptors (TCRs). Antigen presentation by specialized cells is a necessary element of specific immunity. It leads to initiating an immune response. After antigen dependent activation T cells transform to memory and effector lymphocytes.(More)
BACKGROUND The possibility of detection of lymphocytes T specific sensitivity after contact with the allergen (mainly food allergen) even in early age of children has been reported in this paper. METHODS/DATA BASE This is the literature review of basic applied methods such as: lymphocyte blastic transformation in allergen stimulated culture, macrophage(More)
BACKGROUND As the frequency of allergic disease and especially the food allergy in children is still increasing - we undertook studies to determine the specific sensitivity of lymphocytes T in order to improve the diagnostics and monitoring of treatment. The usefulness of evaluation CD69 and PCNA expression of T cells from children with cow's milk allergy(More)
Background Osteosarcoma is the most frequent primary malignant bone tumour, mainly affects children in the first and second decade of life. Causes of the disease are still unknown and reaction of the immune system on its development is very individual. Specific antigen-dependent cellular immunity plays an important role in this process. Cytotoxic T(More)
