OBJECTIVE To examine whether reactive arthritis (ReA) known to occur after a urogenital infection with Chlamydia trachomatis can also follow an infection with Chlamydia pneumoniae, a recently described species of Chlamydiae that is a common cause of respiratory tract infections. METHODS Specific antibodies (microimmunofluorescence test) and lymphocyte proliferation to C trachomatis and C pneu...

Objective: Hematological parameters including neutrophil–lymphocyte ratio (NLR), platelet–lymphocyte (PLR), and monocyte–lymphocyte (MLR) have been demonstrated as new predictors of prognosis activity in various diseases. In this study, we aimed to investigate the associations NLR, PLR MLR with disease severity patients anti-neutrophil cytoplasmic antibody (ANCA) associated vasculitis (AAV). &#...

Secondary antigen receptor gene recombination occurs in developing lymphocytes, and in more mature T and B cells. In the developing lymphocyte, "editing" occurs in response to receptor ligation by autoantigens. As a result of receptor editing, anti-self-reactive cells are converted to non-self-reactive cells, and self-reactive clones are thereby salvaged before negative selection. This antigen-...

The proliferative reactivity of lymphocytes from rat donors maintained under germfree or conventional conditions was examined in mixed lymphocyte cultures stimulated with allogeneic and xenogeneic cell surface antigens. The results show (a) that lymphocytes from conventionally maintained rats are less reactive to human, hamster, guinea pig, and mouse cell surface antigens than to the major H al...

Introduction: The aim of this research was to compare the effect of a 15-day vitamin C and Esupplementation on C reactive protein (CRP), interleukin- 6 (IL-6), cortisol, lymphocyte, andlactate response to a single aerobic training session. Methods: Thirty male college students ofIslamic Azad University-Fars Science and Research Branch of with mean age of 21/53±2/99years, weight 70/03±10/52 kg a...

BACKGROUND Antigen-specific lymphocyte proliferation of synovial fluid mononuclear cells (SF MNC) has been reported repeatedly in reactive arthritis and Lyme arthritis; however, less information is available on serial investigations of SF MNC in the same patients. METHODS In this study, the synovial lymphocyte proliferation to Yersinia, Chlamydia, Shigella and Borrelia burgdorferi was investi...

Objectives: The main aim of our study is to investigate the effectiveness laboratory markers in geriatric patients diagnosed with acute appendicitis emergency department. Methods: A total 73 cases aged over 65 who underwent appendectomy were reviewed retrospectively. Age, sex, values leukocyte count, neutrophil and lymphocyte values, platelets, serum sodium, aspartate aminotransferase (AST), al...

Glucocorticoid receptors were quantitated by a whole cell method in cells from 593 children with acute leukemia at the time of diagnosis. Leukemia cells were also immunologically typed and divided into early pre-B- (not reactive with antibodies to T-lymphocyte antigens, surface immunoglobulin-negative, cytoplasmic immunoglobulin-negative), pre-B- (not reactive with antibodies to T-lymphocyte an...

PurposeThe clinical values of C-reactive protein (CRP) and serum amyloid A (SAA) to distinguish non-severe from severe influenza in children are rarely reported.MethodsBaseline characteristics laboratory results were collected analyzed. Receiver operating characteristic (ROC) curve analysis was used for combined detection indicators with influenza, scatter-dot plots compare the differences betw...
