Using single radial immunodiffusion, its serum level was determined. No significant difference was found between the patients (29.1 \u00b1 4.3 mg\/1; mean \u00b1 1 SD) and normal control group (23.7 \u00b1 4.6 mg\/1). The level of CSF (\u03b1&lt;sub&gt;1&lt;\/sub&gt;-m was determined by the radioimmunoassay of solid antibody system. Its CSF level in the control group was 34.8 \u00b1 16.0\u00b5g\/l, while it was significantly increased in the patients with viral meningitis (p &lt; 0.01) and cerebral infarct (p &lt; 0.05). The level was also elevated in some cases of brain tumor, bacterial meningitis, cerebral hemorrhage, cervical spondylosis, and acute lymphocytic leukemia. There was a positive correlation between \u03b1&lt;sub&gt;1&lt;\/sub&gt;m and albumin levels in CSF. The analysis by CSF\/serum albumin ratio and \u03b1&lt;sub&gt;1&lt;\/sub&gt;-m ratio suggested that the increase of \u03b1&lt;sub&gt;1&lt;\/sub&gt;-m in CSF could be explained mainly by an increase in permeability of the serum \u03b1&lt;sub&gt;1&lt;\/sub&gt;-m through damaged blood brain barrier under these pathological conditions. Its local production within the central nervous system, however, could not be ruled out in these disorders.<\/jats:p>","DOI":"10.1159\/000115528","type":"journal-article","created":{"date-parts":[[2008,2,1]],"date-time":"2008-02-01T05:26:52Z","timestamp":1201843612000},"page":"1-6","source":"Crossref","is-referenced-by-count":13,"title":["Human Alpha\n                    <sub>1<\/sub>\n                    -Microglobulin Levels in Neurological Disorders"],"prefix":"10.1159","author":[{"given":"Yoshikisa","family":"Itoh","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hiromitsu","family":"Enomoto","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kimiteru","family":"Takagi","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Taminori","family":"Obayashi","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tadashi","family":"Kawai","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"127","published-online":{"date-parts":[[2008,1,31]]},"container-title":["European Neurology"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/115528","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/karger.com\/article-pdf\/doi\/10.1159\/000115528","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,4,30]],"date-time":"2026-04-30T11:06:42Z","timestamp":1777547202000},"score":1,"resource":{"primary":{"URL":"https:\/\/karger.com\/article\/doi\/10.1159\/000115528"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2008,1,31]]},"references-count":0,"URL":"https:\/\/doi.org\/10.1159\/000115528","archive":["Portico"],"relation":{},"ISSN":["0014-3022","1421-9913"],"issn-type":[{"value":"0014-3022","type":"print"},{"value":"1421-9913","type":"electronic"}],"subject":[],"published":{"date-parts":[[2008,1,31]]}}}
