the main objective of this study was to evaluate the effect of dietary inclusion of wheat or corn as the main source of starch in prepartum diets on colostrum composition, colostrum igg1 and igg2 concentrations, serum igg1 and igg2 concentrations of calves and efficiency of igg1, igg2 and total ig absorption. for this purpose, thirty primiparous and twenty multiparous holstein cows were used in...

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: mucous membrane pemphigoid (mmp) is considered an autoimmune blistering disease that  predominantly affects mucous membranes. various treatments are available for controlling the diseases, but not all of them may respond. objective: in this review, the data on seventy patients with mmp who were under treatment of intravenous immunoglobulin (ivig) are categorized and then analyzed. t...

toxic epidermal necrolysis is a potentially life-threatening disease, which needs necessary treatment. we present a 12 years old female who was a known case of idiopathic generalized tonic-clonic convulsion and presented with fever, diarrhea and generalized erythematous eruption after 2 weeks of being under treatment with maintenance doses of lamotrigine (ltg) and valproate (vpa). the eruption ...

hyper - immunoglobulin e syndrome is a rare primary immunodeficiency disease characterized by recurrent abscess formation, respiratory tract infections and very high titers of serum ige associated with peculiar face and skeletal features. we report a seven-year old  girl  presenting with persistent productive cough and  history of chronic eczematoid facial lesions since infancy  and  two episod...

conclusions one in five patients undergoing maintenance dialysis in hamadan is seropositive for hepatitis e immunoglobulin g antibody. future studies are needed to investigate the factors contributing to the observed high prevalence rate and the possibility of parenteral transmission of hepatitis e. results thirty patients (19.2%), were seropositive. seropositive patients were not significantly...

celiac disease has been associated with other autoimmune disorders such as autoimmune hepatitis, moreover it is known that t cell mediated immune response to dietary gluten and released cytokines are important for the entheropathy seen in celiac disease. we investigated celiac autoantibodies in patients with autoimmune hepatitis (aih), and chronic hepatitis b (chb). sera from 84 patients with a...

An antibody (Ab), also known as an immunoglobulin (Ig), is a large, Y-shaped protein produced mainly by plasma cell that used the immune system to neutralize pathogens such pathogenic bacteria and viruses. The recognizes unique molecule of pathogen, called antigen, via fragment antigen binding (Fab) variable region. Each tip "Y" contains paratope (analogous lock) specific for one particular epi...

mammalians express several subclasses of the igg molecule. in human being there are four homologous igg subclasses, each of which is structurally unique and has different functions. quantification of igg subclasses is fundamental to clinical assessment and diagnosis of many diseases as such assessments depends on the availability of subclassspecific antibodies (abs), particularly monoclonal ant...
