Evans blue as counterstain in the demonstration of muscle antibodies by immunofluorescence in myasthenia gravis.

چکیده
The binding of muscle antibodies to skeletal muscle was studied by immunofluorescence techniques. The non-specific fluorescence was not significantly reduced by absorption of the conjugate by tissue powder but was abolished by counterstaining with a 0.1% Evans blue. Possible explanations for this effect are discussed. By this method, immunofluorescence may become more useful in the demonstration of muscle antibodies.

متن کاملThymolipoma-associated Myasthenia Gravis with High Titer of Anti-MuSKAb: A Case Report
Myasthenia Gravis (MG) is a neuromuscular junction disorder caused by pathogenic autoantibodies to some parts of the post-synaptic muscle endplates. About 85% of generalized MG patients have autoantibodies against post-synaptic acetyl-choline receptors (AChR). From the 10-15% of the remaining patients, 45-50% are positive for Muscle Specific Tyrosine Kinase-Antibody (MuSK-Ab). It is believed th...

Background: Myasthenia gravis is an autoimmune disorder of neuromuscular junction characterized by skeletal muscle weakness and fatigability. Different genes may control the induction and clinical presentation of this disease. Various HLA alleles are reported as predisposing or protective genetic elements in myasthenia gravis. Objective: The aim of this study was to investigate the probable as...
متن کاملImmunofluorescence method for detecting anti-myocardial antibodies, and its use in diagnosing heart disease.
Demonstration of autoimmune antibodies to myocardial tissue enables one to detect and assess cardiac disease long after abnormalities in serum enzyme activities are no longer measurable. We describe and indirect immunofluorescence procedure in which cryostat sections of rat heart (ventricle) and Evan's Blue counterstaining are used to detect anti-myocardial antibodies. Sena from patients with m...
متن کاملComparison of Two Different Induction Doses of Atracurium in Myasthenia Gravis in Patients Undergoing Thymectomy
Introduction:yasthenia gravis is an autoimmune disorder resulting from a decreased number of active acetylcholine receptors at the neuromuscular junction. Thymectomy is one of its current treatments. Due to sensitivity of myasthenic patients to non-depolarizing muscle relaxants and also the interaction of this medication with anti-cholinestrase drugs, determining the dosage of non-depolarizing ...
