amegakaryocytic thrombocytopenia (amt) is a rare cause of acquired thrombocytopenia. the pathogenesis and treatment of amt is not clearly known. here we demonstrate a 50-year-old man presented with the clinical manifestations of severe thrombocytopenia (7000 platelets/µl) with a marked decrease to absent of megakaryocytes in the bone marrow. the patient did not respond to intravenous immunoglob...

background: anti-sperm antibody (asa) can decrease sperm motility and, therefore, it is a cause of male infertility. the aim of this study was to evaluate the effects of varicocelectomy on anti-sperm antibody in patients with varicocele. methods: this observational study was conducted on 90 patients with varicocele at sina and imam khomeini hospitals during 2006 to 2009. all varicocelectomy can...

conclusions thyroid dysfunction was not higher in sle patients compared to healthy individuals. however, anti-tg antibodies were higher in sle patients. it has not yet been established that thyroid function tests should be performed routinely in sle patients. results the mean age of sle patients and controls were 32.16 ± 9.19 and 32.48 ± 9.47 years, respectively (p = 0.821). patients had signif...

objective(s): enterotoxigenic escherichia coli (etec) strains are one of the primary causes of diarrhea in newborn calves and in humans, pigs, and sheep. igy technology has been identified as a promising alternative to generating a mass amount of specific antibody for use in immunotherapy and immunodiagnostics. the purpose of this study was to produce specific antibody by egg yolk antibody (igy...

Passively acquired antibodies through colostrum will protect calves against etiological agents of neonatal calf diarrhea. Among them enteric diseases due to strains of Enterotoxigenic Escherichia coli (ETEC) are the most commonly occurring form of colibacillosis in newborn calves. Specific antibodies against whole ETEC cells and total immunoglobulin G in dam serum, colostrum and calf serum were...

systemic sclerosis is a generalized disorder of connective tissue clinically characterized by thickening and fibrosis of the skin and by distinctive forms of involvement of internal organs. one of the hallmarks of systemic sclerosis is the presence of serum autoantibodies against a variety of nuclear and cytoplasmic antigens. the primary purpose of this study was to identify the autoantibodies ...

1. Antisera have been produced in chickens with specific precipitates from Type II pneumococcus horse and rabbit antisera. 2. Specific precipitates from anti-Types I and II pneumococcus horse sera removed the same amount of antibody from the chicken anti-horse specific precipitate serum. Specific precipitates from horse antisera to diphtheria toxin and to crystalline egg albumin removed about o...

background: celiac disease is a common autoimmune disorder that is diagnosed based on clinical case identification, serological screening, and duodenal histology. however, the existence of mild clinical forms, such as seronegative cases with patchy atrophy and potential celiac disease, can make it difficult to determine a definitive diagnosis. the seronegative patients with celiac disease can i...

Objective: To identify auto-antibodies in systemic sclerosis with interstitial lung disease (ILD). Method: This was a descriptive categorical study on auto-antibody profile patients visiting the Rheumatology Clinic of Dr. Hasan Sadikin General Hospital, West Java, and Bandung during period January 2018 to December 2019 who were registered Java Systemic Sclerosis Registry. Auto-antibody identifi...

diagnosis of hepatitis b is routinely based on of serological assay of hepatitis b surface antigen (hbsag). occult hepatitis b virus (hbv) infection is generally defined as the detection of hbv -dna in the serum or tissues of subjects who have negative test for hbsag. transmission of hbv infection has been documented from hbsag negative, anti-hbc positive blood and organ donors. the aim of this...
