Background and aims: Toxoplasmosis is a very common disease in the world. Two types of acquiredtoxoplasmosis have been detected. In the chronic toxoplasmosis, the abnormality of tissue functionis little but, in acute toxoplasmosis, function of RES system becomes interrupted. The assessment oftoxoplasma antibody with tissue enzymes in this stage is very important. Furthermore, ...
In the present study, we investigated antibody productions of IgA and other classes, such as IgE and IgG1, in mice as possible evidence of the protective effects of Spirulina toward food allergy and microbial infection. An increase of IgE antibody level in the serum was observed in the mice that were orally immunized with crude shrimp extract as an antigen (Ag group). The antibody level, howeve...
In the suppression of the growth of a mouse lymphoma 6C3HED by antibody, the effectiveness of antibody in suppressing growing or established tumor cells and comparable number of freshly injected tumor cells is quantitatively similar. The effectiveness of antibody diminishes markedly when the number of tumor cells per mouse reaches the level of 10(6) due to the development of a macrophage shorta...
Effects of cyclophosphamide (CY) on the antibody titer level and incidence and severity of swine serum (SS)-induced bile duct lesion (BDL) were examined. BDL induced by 0.2 ml of SS per head twice a week for 2 weeks was characterized by hyperplasia of biliary epithelial cells, proliferation of mucous glands, and periductal infiltration of eosinophils with mild fibrosis. CY showed no significant...
background: toxoplasmosis is a zoonotic disease with high seroprevalence worldwide. several immunological methods have been described for diagnosis of toxoplasmosis. objective: to determine the parasitemia period in patients infected with toxoplasma using pcr and comparing serological data with molecular results. methods: 154 serum samples from patients with toxoplasmosis were examined. presenc...
erythropoietin (epo) was first known as a factor for red blood cell proliferation and differentiation. recent studies show the effects of epo on immune system. in this study the antihuman leukocyte antibody (anti-hla) titer were determined in five groups of rats, which had been sensitized with human lymphocyte. also, the effects of stimulation's frequency and dose of recombinant human eryt...
The detection of antibody to the Borrelia burgdorferi C6 peptide by use of enzyme-linked immunoassays is a widely accepted method for the diagnosis of Lyme disease spirochete infection in dogs and in humans. Antibody to the C6 peptide is highly specific for B. burgdorferi and declines following treatment of dogs and humans exposed to B. burgdorferi. A quantitative assay for determining C6 antib...
In this study, immune responses against Streptococcus iniae infections in rainbow trout (Oncorhynchus mykiss) were analyzed. Anti-streptococcal antibody (ASA) levels, respiratory burst activity (RBA), phagocytic activity (PA) and phagocytic index (P index) were measured in kidney macrophages. Fish were allocated to three experimental groups (n = 50 per group): survivors of natural S. iniae inf...
Abstract Background and objectives: Helicobacter pylori is a Gram- negative bacteria causing diseases such as peptic ulcer and gastric cancer. In this research ,we determined the level of three types of antibody IgG, IgM and IgA in ordinary people of Izeh. Material and Methods: After collecting blood samples from 263 cases, the serum were obtaind and using the ELISA method the amount of IgG, Ig...
