multiple sclerosis (ms) is a chronic inflammatory disease of the central nervous system characterized by widespread inflammation, focal demyelination and a variable degree of axonal and neuronal loss. ionic conductances regulate t cell activation as well as neuronal function and thus have been found to play a crucial role in ms pathogenesis. since present therapeutical approaches are only parti...
multiple sclerosis is an autoimmune cns-disease characterized by inflammatory neurodegenerative events occurring with de- and remyelination. recent evidence show that demyelinated neurons are less excitable than myelinated ones while at early stages of remyelination these neurons seem to be hyperexcitable. the latter is a transitory condition that, very likely, leads to impaired neuronal networ...

Objectives—To test the hypothesis that irrecoverable neurological deficit in multiple sclerosis is associated with axonal loss. Methods—H magnetic resonance spectroscopy (MRS) was carried out in a group of patients with clinically definite multiple sclerosis (n=31). Using this technique, the apparent concentration of NA ([NA] the sum of N-acetyl aspartate (NAA), a neuronal marker, and N-acetyla...
results when the two ms groups were compared together, we found that cr was significantly increased (p value=0.008) and naa/cr was significantly decreased (p value=0.03) in non-enhancing lesions in ppms compared with rrms. there was no significant difference in naa, cho or naa/cho between the two ms subtypes. conclusion mrs is a potential way to differentiate ppms and rrms. objectives we compar...
background: cognitive impairment is one of the most crucial disorders among multiple sclerosis (ms) patients. since ms is an inflammatory disease and boswellia papyrifera has anti-inflammatory effects, the influence of b. papyrifera on cognitive impairment in ms patients has been investigated in the present study. methods: in this clinical trial, 80 ms patients who referr...
مالتیپل اسکلروز (ms) یکی از شایع ترین بیماری های خودایمنی است که سیستم عصبی مرکزی را درگیر می کند.تاکنون علت اصلی این بیماری شناخته نشده است اما مطالعات اپیدمیولوژیکی به روشنی نشان می دهد که هم عوامل محیطی و هم عوامل ژنتیکی در ابتلا به این بیماری دخالت دارند. هدف از این تحقیق بررسی ارتباط یک سری پلی مورفیسم های تک نوکلئوتیدی موجود در پروموتر ژن مهار کننده nf-?bکه مهمترین آن ikb-? می...
multiple sclerosis (ms) is an autoimmune disease of the central nervous system (cns) which causes demyelination of the nerve fibers. the etiology of this disease is not well understood but it is believed that t helpers play a central role in ms. numerous findings support the view that th17 cells play an essential role in pathogenesis of ms and il-17 secreting t (th17) cells have a role in infla...
when pooled immunoglobulin g (igg) from patients with multiple sclerosis (ms) was used to probe a human fetal spinal cord λgt 11 cdna library, the igg was found to bind to a predicted epitope of human mitochondrial nd4 sequence. to investigate the involvement of the nd4 as an autoantigen in ms, we determined the presence of specific antibody in the serum of ms patients and serum samples of some...
