background lichen planus is a disease with unknown etiology that affects the skin and the mucous membranes. immune dysregulation in the pathogenesis of oral lichen planus (olp) is well-known phenomenon. objectives in this study, we compared the levels of the peripheral blood t lymphocytes between patients with olp and control group. patients and methods in this study, 32 and 16 patients respect...
background : an elevation in the mean percentages of the gamma delta t lymphocytes per total t cells in the epithelium of the small intestine has a diagnostic value for celiac disease. this study aimed to measure the percentages of the peripheral blood gamma delta t lymphocytes in the adults' celiac disease and healthy controls. materials and methods: in this case-control study the absolute nu...
background: celiac disease (cd) is a small bowel enteropathy caused by permanent wheat gluten intolerance. one of the earliest signs of the mucosal immune activation in cd is an increase in the intestinal intraepithelial lymphocytes (iiels) count in the small intestinal epithelium. although most of those iiels express ??tcr, cd is characterized by an increase in the gdtcr + iiels. objective: th...
background: human peripheral blood nk cells constitutively express cd56 and cd16 antigens. peripheral blood nk cells seem to be strongly related with decidual nk cells, and may reflect the decidual nk cell functional status. there are varied reports concerning the relationship between nk cell cytotoxicity in women with recurrent spontaneous abortion. objective: to study nk activity in women wit...
objectives the cause of rheumatoid arthritis (ra) as a chronic inflammatory autoimmune disease is still unknown. it appears that both genetic and environmental factors play a role in its pathogenesis. recent studies reveal that in addition to the cns, immune cells synthesis neurotransmitters so that these catecholamines can regulate immune functions. the aim of this study is to evaluate the dop...
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...
bleomycin (blm)as an anti-cancer agent causes tissue toxicities through dna damaging and cell deaths. the aim of this study was to investigate the effects of thymol against genotoxicity and anti-proliferation induced by blm in normal human lymphocytes and ovarian cancer cells.peripheral blood samples were collected from human volunteers and were incubated with thymolat different concentrations ...
Background and Aims: Patients with Hyper-IgE syndrome suffer from fungal and bacterial infections, especially Candida albicans and Staphylococcus aureus. Due to the important role of T helper17 (Th17) lymphocytes in defense against fungal infections, the percentage of Th17 lymphocytes was studied in the patients with autosomal recessive hyper-IgE syndrome (AR-HIES). Materials and Methods: In...
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: Tetracyclic antidepressants-mirtazapin is one of antidepressants drug that exhibits both noradrenergic and serotonergic activity. It is commonly used to treat major depressive disorder. The genotoxic effect of mirtazapine has not been examined previously. The purpose of this study was to investigate the genotoxic and cytotoxic effects of mirtazapine on human peripheral blood lymph...
