identification of acid-fast bacilli (afb) in sputum or tissue samples is among definite diagnostic methods of tuberculosis. however, this method of diagnosis is restricted by certain limitations.   serologic diagnosis of tuberculosis (tb) has been used for a long time. the aim of this study was to determine the sensitivity and , specificity of antigen 60 (a60) igg, iga, igm test results in tb d...

conclusions based on the findings of the present study, the frequency of toxoplasma infection is high in the studied population, although it is fairly close to the findings of reports from the other areas of iran. results in total, 1910 (29.87%) out of 6393 subjects were found to be infected with toxoplasma gondii. in terms of the seropositivity, 1871 (32.42%) out of 5770 and 128 (2.14%) out of...

non-enzymatic glycosylation of proteins is one of the key mechanisms in the pathogenesis of diabetic complications. glycation of igg is of special interest due to its possible influence on the functionality of immunoglobulins and overall immuno-competence. the aim of this study was to clarify more details of in vitro glycation of igg and to study the effect of this modification on its interatio...

since the incidence of symptomatic congenital cytomegalovirus infection is low (~0.05%) and risk factors are not well defined, it is difficult to develop strategies for prevention. the aim of this study was to recognise the utility of specific immunoglobulin g avidity analysis for distinguishing primary infection from past/recurrent infection. sera from 50 women with cytomegalovirus specific im...

The aim of the current research was to investigate the effect of aluminum exposure on humoral immunity (immunoglobulin G and immunoglobulin M serum levels), function enzymes, and histological alterations in the liver of rats. Materials & Methods: Sixteen albino male rats at fifteen weeks were grouped into four groups, and administered with aluminum chloride at 35g/Kg of body weight for 8, 12 ...

background: it seems that the success of vaccination for cancer immunotherapy such as dendritic cell (dc) based cancer vaccine is hindered through a powerful network of immune system suppressive elements in which regulatory t cell is the common factor. foxp3 transcription factor is the most specific marker of regulatory t cells. in different studies, targeting an immune response against regulat...

to investigate the igg content and its variations in uterine fluid (uf) during the estrous cycle of the cow and to compare them with those of the blood serum (s), six pairs of serum and uf samples for each phase of the cycle selected out of 240 bovine genital tracts and blood samples were collected from urmia abattoir. the uf samples were collected by gentle scraping of the endometrium using a ...

forty patients with cataracts, as well as 40 patients with proven ocular toxoplasmosis were enrolled in this prospective clinical study. serum igg and aqueous igg in both groups were measured by enzyme-linked immunosorbent assay (elisa) and the corresponding ratios were calculated. serum igg/aqueous humor igg ratio was less than 100 in the patient group and more than 100 in the control group. o...

Background and Purpose: Although molds are regarded as the main fungal allergen sources, evidence indicates that spores of Basidiomycota including Agaricus bisporus (A. bisporus) can be also found at high concentrations in the environment and may cause as many respiratory allergies as molds. The aim of the present study was to evaluate specific immunoglobulin E (IgE) and immunoglobulin G (IgG) ...
