Материалы и методы: Исследование проведено в 3 этапа. На 1-м этапе исследовали концентрацию β-ТР в крови, ЦСЖ и выделениях из носа у больных после трансназальных операций, после ЧМТ или со спонтанной назореей. На 2-м этапе определяли концентрацию β-ТР в ЦСЖ у 8 больных с гнойным менингитом и у 7 больных с субарахноидальным кровоизлиянием (САК), а также концентрацию β-ТР в крови у 7 больных с острой почечной недостаточностью (ОПН). На 3-м этапе оценивали концентрацию β-ТР в выделениях у 17 пациентов с подозрением на базальную ликворею. Определение β-TP проводили на автоматическом нефелометре BN ProSpec путем нефелометрического теста с реактивом N Latex betaTP. Результаты: В результате анализа образцов крови, ЦСЖ и выделений у 13 больных установлено, что концентрация β-TP в крови составила 0,5±0,1 мг/л (от 0,4 до 0,7 мг/л), в ЦСЖ - 17,2±8,2 мг/л (от 9,7 до 37,7 мг/л). при САК концентрация β-TP в ЦСЖ не меняется (составила 16,2±7,0 мг/л), а при менингите концентрация β-TP в ЦСЖ снижается в среднем в 2,2 раза (среднее - 7,9±4,2 мг/л, min - 4,3 мг/л, max - 15,1 мг/л). Содержание β-TP в крови у больных с ОПН повышается незначительно - в среднем до 1,5±0,9 мг/л. При обследовании больных с подозрением на базальную ликворею нефелометрический тест позволил верифицировать наличие ЦСЖ в выделениях в 8 (36,4%) из 22 проб, что повлияло на лечебную тактику. Лабораторный метод оказался неэффективным при микроликворее. Заключение: нефелометрический тест на β-TP является эффективным для диагностики базальной макроликвореи, однако при трактовке результатов следует учитывать наличие у больных гнойного менингита и ОПН.</p></abstract><trans-abstract xml:lang="en"><p>Objective: to estimate the possibility of liquorrhea diagnostics by identification of β-trace protein (ß-ТР) concentrations in nasal discharges. Material and methods: The study was conducted in 3 stages. First stage included examination of β-ТР concentration in blood, CSF and nasal discharges at patients underwent transnasal operations or suffered from head injury or from idiopathic nasorrhea. Second stage included the identification of β-ТР in CSF at 8 patients with purulent meningitis and at 7 patients with subarachnoid hemorrhages (SAH) as well as blood concentration of β-ТР at 7 patients with acute renal failure (ARF). Third stage included the estimation of β-ТР concentration in nasal discharges at 17 patients suspected on basal liquorrhea. The identification of β-TP was conducted using automatic nephelometer BN ProSpec by nephelometric test with reagent N Latex betaTP. Results: We determined that blood concentration of β-TP was 0,5±0,1 mg/l (from 0,4 till 0,7 mg/l), CSF concentration of β-TP - 17,2±8,2 mg/l (from 9,7 till 37,7 mg/l) analyzing samples of blood, CSF and nasal discharged at 13 patients. The CSF concentration of β-TP unchanged at patients with SAH and was 16,2±7,0 mg/l, but this CSF concentration of β-TP decreased in 2,2 times at average (mean - 7,9±4,2 mg/l, min - 4,3 mg/l, max - 15,1 mg/l) at patients with meningitis. Blood concentration of β-TP increased slightly (up to 1,5±0,9 mg/l at average) at patients with ARF. The nephelometric test allowed identifying CSF in nasal discharges in 8 (36,4%) from 22 samples during examination of patients with suspect for basal liquorrhea that influence on treatment strategy. Laboratory method was ineffective for microliquorrhea diagnostics. Conclusion: nephelometric test for β-TP identification is effective for diagnostics of basal macroliquorrhea however purulent meningitis and acute renal failure must be taking into account during reading the results of analyzes.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>ликворея</kwd><kwd>менингит</kwd><kwd>черепно-мозговая травма</kwd><kwd>САК</kwd><kwd>β-trace protein</kwd><kwd>liquorrhea</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Bachmann-Harildstad G.
