background and objectives: complement proteins are some of the most important plasma proteins of the innate immune system. impaired immune function is reported in subjects who are iron deficient, and there are documents that these patients are prone to infection. this study was conducted to show whether serum c3 and c4 complement change in adult nonpregnant female with iron deficient anemia or ...

Recurrent aphtus stomatitis (RAS) is an oral mucous lesion in patients with no other signs of disease. Investigators have always notified the role of immune system especially humoral immunity in aphtus immunopathogenesis. The aim of this case-controlled study was to measure amount of serum immonogiobulins (A,G,M) and complement component (C3 C4) in patients with RAS and to evaluate any relation...
Background: The components of the classical complement pathway play an important role in the pathogenesis of systemic lupus erythematosus (SLE) and are reportedly useful biomarkers of disease activity. In this study, we evaluate disease activity, complement function (total hemolytic complement, CH50) and complement protein levels (C3, C4, C3d, C4d, SC5b-9), comparing the results of patients wit...
objective despite numerous reports on the effects of meal frequency on biochemical parameters such as plasma lipid profile, glucose and insulin, there is almost no study to investigate the influence of meal frequency on immune system. in the present article, for the first time, the effect of meal frequency on complement components c3 and c4, as key components of the complement system, has been ...
Background: Coronary artery disease (CAD) is one of the most important and lethal diseases in the world. CAD represents a board spectrum of disease from silent ischemia at one end to sudden cardiac death at the other end. The middle of this spectrum consists of acute myocardial infarction (AMI) and unstable angina pectoris (UA). Recent data show that the inflammatory process plays a major r...
Background and Objectives: Deficiency in the complement system can lead to some autoimmune diseases, such as systemic lupus erythematosus. The purpose of this study was to investigate the levels of C3 and C4 complements in unstimulated saliva of individuals with oral lichen planus (OLP) and healthy subjects. Methods: In this case-control study, 31 healthy individuals and 31 patients with OLP en...
A phylogenetic analysis of DNA sequences from the C3/C4/C5 complement-component family of vertebrates supported the hypothesis that the C5 gene diverged first from the common ancestor of C3 and C4 and that C3 and C4 diverged later. The close relationship of C3 and C4 was further supported by the fact that a hagfish complement-component gene showed evidence of being more closely related to both ...
Studies were undertaken to evaluate content of IgG, IgM, C3, C4, CH50 and proteines of sera from 53 drug addicts by immunological methods. Results shows an increase of IgG and no significant variatrion in the level of other Ig(S). In the same time we have seen an augmentation of gamma globuline in the protein electrophoresis pattern. The level of C3 and C4 of complement component rest unchanged.
Abs to acetylcholine receptor (AChR) and complement are the major constituents of pathogenic events causing neuromuscular junction destruction in both myasthenia gravis (MG) and experimental autoimmune MG (EAMG). To analyze the differential roles of the classical vs alternative complement pathways in EAMG induction, we immunized C3(-/-), C4(-/-), C3(+/-), and C4(+/-) mice and their control litt...
