A part of the immune system that improves (complements) the ability of antibodies and phagocytic cells to clear microorganisms and injured cells from an organism, attacks the pathogen's cell membrane, and encourages inflammation called complement system. It is main part of immune system. Over thirty proteins and protein pieces compose the complement system, including cell membrane receptors, an...
The present study was undertaken to analyze the status of immune system (responses & deficiencies) in children with Giardiasis aged between 2 to 9 years for probable correlation between blood serum & cellular elements and Giardiasis infection. With approval of Giardiasis through utilizing classic laboratory methods within parasitologic domains, blood samples of the affected children with Giardi...
, Shaheed Beheshti University of Medical Sciences Abstract: Background: The main surgical side effects and complications in many cases are due to the long duration of the anesthesia. Obviously these phenomena are related to the use of anesthetic drugs which have effects on liver blood flow, immune system and homeostasis. One important effect is activation of complement system. In this stud...
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: 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 ...
Abstract Background and Objectives One of the side effects of immunoglobulin administration is the activation of the complement system related to the high concentration of aggregates/large polymers in the production process. Measuring anticomplementary activity (ACA) is important in pharmaceutical quality control and is a criterion of spontaneous activation of complement system in immunoglobuli...
In the present study, the effect of the intraperitoneal injection of Carthamus tinctorius extract on non-specific immune system and some serological of Oncorhynchus mykiss has been investigated. To this end, the fish with average weight of 100±10 gr were intraperitoneally injected by different levels of safflower extract. In this regard, a negative control group (no injection), a positive contr...
Bacterial endotoxins and antigen-antibody aggregates activate complement, accelerate blood coagulation, and are implicated in intravascular blood clotting (1-7). Tha t their effect on blood coagulation proceeds through the activation of the complement system has been suspected bu t has never been shown. We have found that these and other complement-activating materials initiate blood coagulatio...
Activation of the alternative pathway of complement is implicated in common neurodegenerative diseases including age-related macular degeneration (AMD). We explored the impact of common variation in genes encoding proteins of the alternative pathway on complement activation in human blood and in AMD. Genetic variation across the genes encoding complement factor H (CFH), factor B (CFB) and compo...
