ionizing radiation causes dna damage and chromosome abbreviations on normal cells. the radioprotective effect of celecoxib (clx) was investigated against genotoxicity induced by ionizing radiation in cultured human blood lymphocytes. peripheral blood samples were collected from human volunteers and were incubated at different concentrations at 1, 5, 10 and 50 μm of clx for two hours. at each do...
The study of pathogenic systems involved in multiple sclerosis (MS) is essential for the development new therapies. Objective : to determine contribution B-lymphocytes production IL-17 MS with an assessment ability B-cells induce differentiation Th17 and own by this pathology. Material methods . A total 81 subjects were examined, 68 whom patients diagnosed MS, 13 healthy individuals. concentrat...
Contact hypersensitivity (CHS) mouse model induced by 2, 4-dinitrofluorobenzene (DNFB) is thought to be a T helper 1 (Th1)-dominant response and used for investigating anti-inflammatory and immunosuppressive agents. However, it is hardly used for screening large-scale drugs because of the large number of animals and complex mechanisms involved in-vivo. In this study, we focused on whether T lym...
Background: The pathogenesis of inflammatory bowel disease is complex and multifactorial. Studies have led to the current concept that Toll-like receptors represent key mediators of innate host defense in the intestine, and they are involved in maintaining mucosal as well as commensal homeostasis. We studied the possibility of simvastatin and antagonist of receptors of interleukin-1 for pharmac...
Down's syndrome (DS) is the most common chromosomal abnormality in human. Subjects with DS are known to be peridisposed to develop leukemia. The molecular basis of the association between DS and leukemia is unknown. The unscheduled DNA synthesis (UDS) test measure the ability of DNA-repair in mammalian cells after excision of a stretch of DNA containing the region of damage induced by chemical ...
This study is aimed to investigate the effect of female autoserum on HLA-DR expression in various subpopulations lymphocytes obtained from spouses with children sporadic congenital heart defects without chromosomal diseases. 78 married couples disease were included group. The control group was formed 35 healthy children. immune response a mixed culture evaluated by an increased relation spontan...
Transfusion associated graft versus host disease(GVHD) is a serious clinical complication that occurs in some cases after blood and blood products transfusion. The mortality ratio of this disorder is very high and in over 90% of cases lead to patients’ death. The procedure routinely used to inhibit GVHD is inactivation of donor blood lymphocytes and prevention of their proliferation in recipien...
Introduction: Along with the increased use of cardiac imaging at clinics there is increased attention to the potential risks related to the methods used like magnetic resonance (MR) and it cannot be ruled out that MR can alter DNA structure. The aim of this review is to assess the impact of routine cardiac magnetic resonance (CMR) scanning on DNA damages in human T lymphocytes....
