Background. The problem of treatment phlegmon the maxillofacial region and neck remains one most urgent problems surgery. Aim. To determine degree influence local Low Level Laser Therapy (LLLT) on quantitative functional characteristics immunocytes humoral factors in peripheral blood lavage fluid neck. Material methods. We have examined treated 60 patients with Of these, 30 people made up group...

Background Rheumatoid arthritis (RA) is associated with arteriosclerosis. The inflammation present in the disease responsible for this cardiovascular (CV) comorbidity. complement system (C) an essential component of immune response that has function enhancing inflammatory response. C been implicated etiopathogenic mechanisms CV and RA. Objectives Our objective was first to determine serum level...

The possible role of complement activation in the development of transient granulocytopenia during nylon fiber filtration leukapheresis ( FL) was studied in five normal donors. No changes in hemolytic complement (CH50) titers were observed in the donors’ circulating plasma at any point in the procedure. However, comparison of preand postfilter blood samples drawn 1 mm after donor blood passed t...

background: the serum levels of c 3 , c4, and the total hemolytic activity of complement system (ch50) of patients ex­posed to mustard gas (mg) in the battlefield were measured in this study. methods: c3 and c4 were measured by single radial immunodifusion and ch50 was evaluated according to total hemolytic activ­ity of the serum. results:   the serum levels of c 3 showed a significant increase...

BACKGROUND To determine the prevalence of cryoglobulins in Iranian patients with systemic lupus erythematosus (SLE) and evaluate the correlation of cryoglobulins with disease activity in these patients. MATERIALS AND METHODS In a cross-sectional study, we investigated 80 consecutive women who fulfilled the 1982 revised criteria of the American College of Rheumatology for the classification of...

The complement is thought to be involved in the pathogenesis of multiple liver disorders. However, its role in patients with HBV related acute-on-chronic liver failure (HBV-ACLF) remains unclear. Serum levels of the third and fourth complement components (C3, C4) and complement function (CH50) were examined in this prospective, observational study. Associations between their expression and dise...

Classical pathway haemolytic complement (CPHC) of the dromedary was assayed under standardised conditions. A total of 14 indicator systems of red blood cells (RBC) and haemolysins were investigated. Highest CH50 titre was obtained with rabbit RBC sensitised with goat haemolysin. Among the factors investigated were: ionic strength, Mg2+, Ca2+, ethylenediaminetetraacetic acid (EDTA) concentration...

The ability of MIC to induce complement activation in vitro and in vivo was investigated. For the in vitro studies, both human and guinea pig serum or EDTA-plasma samples were exposed to 1167 to 1260 ppm MIC vapor for 15 min at room temperature. The human serum samples exposed to MIC showed significant reductions in Factor B, C2, C4, C3, C5, and total hemolytic complement CH50 activity levels. ...

In a group of 46 patients with retinitis pigmentosa (RP) we studied the presence of circulating immune complexes (CIC) and the alterations in the complement system. Our results showed the presence of CIC in 43.5% of the patients studied, reduced levels of the complement components C3 and C4 (p less than 0.001), and of the haemolytic activity CH50 (p less than 0.001) when compared with a control...

Results A hundred and twenty nine patients (69M:60F) were included in the study. The age of the patients ranged from 2 months (m) up to 64 years old (mean= 96.2m; median=48m). The following serogroups were identified: type C, 36.4%; B, 20.2%; W135, 1.5% and 41.9% had no serogroup identified. CH50 and AP50 values were below the reference levels in 48 patients (37.2%) and 97 patients (75.2%), and...
