introduction : in order to evaluate the role of thyroid autoimmunity in patients with goiter, this study was done 10 years after implementation of iodine supplementation program ( iodised salt). the serum levels of thyroid peroxidase antibodies (anti tpo) and thyroglobulin antibodies (anti tg) were studied in a group of patients with simple goiter and compared with normal controls. materials an...

introduction: vaccination with the major surface antigen of hepatitis b virus (hbsag) induces anti-hbs antibody production and level of 10 iu/l is considered protective. it has been shown that the level of anti-hbs antibody does wane after vaccination. the aim of this study was to evaluate the persistence of anti-hbs antibodies in healthy iranian children 10 years after primary vaccination. met...

background: erythropoietin (epo) was first known as a factor for red blood cell proliferation and differentiation. new studies show the effects of epo on immune system. objective: in this study, the effects of pretreatment with recombinant human erythropoietin (rhuepo) on the anti-human leukocyte antibody (anti-hla) titer were determined. methods: three groups of rats were sensitized with human...

purpose: to evaluate the vascular occlusion in coats’ disease   methods: in this non-comparative case series, 13 consecutive patients with coats’ disease from january 2011 to september 2011 were included. the hypercoagulability states were evaluated in these patients.   results: the mean age of the patients in this series was 15.4 years. all but one patient had high anti-cytomegalovirus antibod...

We describe an enzyme-linked immunoassay for measuring human placental lactogen (HPL) in serum. After suitable dilution, sera are pipetted into the wells of polyvinyl microtitre plates previously coated with anti-HPL. After incubation the sera are decanted, and replaced by a conjugate of horseradish peroxidase and anti-HPL. An amount of enzyme proportional to the concentration of HPL in the ser...

background: infection is now the most common cause of morbidity in systemic lupus erythematosus (sle). there is lack of information regarding the specific antibody forma-tion in response to vaccines in young sle patients. objective: to determine the efficacy of anti-tetanus antibody response in young patients with sle. methods: forty sle pa-tients with mean age of 14.1 years (range: 7-21) and 6...

This work describes the whole-mount immunohistochemistry staining method in detail, using neurofilament protein antibody to label the innervation of the biliary tract in Suncus murinus (S. murinus ). First, the specimen was dissected from S. murinus and fixed in 4% paraformaldehyde (PFA). Second, an enzymatic treatment and potential endogenous peroxidase inactivation were performed. The specime...

In this study, a polyclonal antibody with high avidity and specificity to the potent hypocholesterolaemic agent rosuvastatin (ROS) has been prepared and used in the development of highly sensitive enzyme-linked immunosorbent assay (ELISA) for determination of ROS in plasma. ROS was coupled to keyhole limpt hemocyanin (KLH) and bovine serum albumin (BSA) using carbodiimide reagent. ROS-KLH conju...

the onset of infections by leishmania parasites mainly caused by amastigote growth inside the macrophages. one of the important properties of lesion-derived amastigote is thought to be the attachment of various host proteins including immunoglobulins on the surface of amastigote. in this study, the presence of immunoglobulins on the surface of lesion-derived amastigotes was detected by western ...

AIMS To develop an indirect ELISA using the heat shock protein (hsp60) of Chlamydia trachomatis as antigen. METHODS The hsp60 gene was amplified by PCR, expressed in the vector pDEV-107 and transformed into Escherichia coli. The recombinant protein, expressed as a beta-galactosidase fusion product, was captured onto a solid phase using a monoclonal antibody directed against beta-galactosidase...
