The information concerning their levels in non-metastatic breast cancer is inconclusive. The aim of our study was to examine some acute phase proteins (CRP, orosomucoid, prealbumin, alpha 2-macroglobulin and transferrin) in patients with various clinical stages of breast cancer before hormonal and/or chemotherapy and 3 and 12 months after its institution and to assess the influence of their levels on the outcome of patients.</p><p><strong>Methods and results: </strong>Altogether 59 women with breast cancer in clinical stage 0-IV, median age 62 years (47 of them after menopause) were examined. One patient was in stage 0, ten patients in stage I, 24 patients in stage IIA, 11 patients in stage IIB, five patients in stage III and eight patients in stage IV. Acute phase proteins (CRP, orosomucoid, transferrin, prealbumin and alpha 2-macroglobulin) were examined in the sera samples using microturbidimetry. Serum levels of CRP and orosomucoid were higher in patients with breast cancer in all stages compared to controls. Serum levels of CRP (resp. of orosomucoid) higher than mean +2 SD had 30.5% (resp. 39%) of patients with breast cancer. One year after the beginning of therapy serum levels of CRP and orosomucoid significantly decreased, however, in case of orosomucoid they remain higher compared to controls. Serum levels of CRP and orosomucoid correlated before therapy in patients with breast cancer one to another and also with serum levels of soluble TNF (tumour necrosis factor) receptor type I and soluble ICAM-1.</p><p><strong>In conclusion: </strong>Patients with breast cancer before hormonal therapy and/or chemotherapy had compared to controls increased serum levels of CRP and orosomucoid, however, there was no difference between stages I-III. Observed correlation between serum levels of CRP and soluble TNF receptors suggests the important role of proinflammatory cytokines in stimulating their hepatic synthesis also in patients with breast cancer. Putative prognostic role of persistently increased levels of orosomucoid in patients with non-metastatic breast cancer warrants further investigation.</p>","PeriodicalId":76514,"journal":{"name":"Sbornik lekarsky","volume":"104 2","pages":"121-32"},"PeriodicalIF":0.0,"publicationDate":"2003-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"24042872","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"[Microsleep from the electro- and psychophysiological point of view].","authors":"J Faber,&nbsp;M Novák,&nbsp;P Svoboda,&nbsp;V Tatarinov,&nbsp;T Tichý","doi":"","DOIUrl":"","url":null,"abstract":"<p><p>Impaired wakefulness in machine operators poses a danger not only to themselves but often also to the public at large. While on duty, such persons are expected to be continuously, i.e., without interruption, on the alert. For that purpose, we designed and carried out an experimental model of continuous vigilance monitoring using electroencephalography (EEG) and reaction time measured as the latency of the proband's reaction to sound. If constructed, the set together with other logical elements and an alarm can make for an automatic detection of vigilance and, possibly, also of arousal stimuli in cases of microsleep. We found the following new facts and confirmed the validity of some of the earlier ones: Vigilance is marked by alpha activity in the EEG record (oscillation of 8-13 Hz) and reaction time (RT) of 200-400 ms (milliseconds). Sleep is characterized by theta and delta activities (4-7 and 0.5-3.5 Hz respectively) with no reaction. Between wakefulness and sleep there are at least two stages: relaxation with prolonged RT of 400 to 800 ms and increased EEG alpha, sometimes also beta activities. Then there is the hypnagogic phase with disintegrating alpha and growing theta or even delta activities and an RT of 800 up to 1200 ms. Changes in the EEG and its spectrum and their actual localization on the cranial surface exhibit individual differences; hence, no straightforward categories for the above stages can be established. As for changes in vigilance in the relaxation and hypnagogic phases as well as in the processes of mentation, the most significant are the alpha and delta, less so the theta and beta bands. The most suitable sites for the detection of those changes on the skull surface are temporo-parieto-occipital (TPO) regions, i.e., those over the posterior parts of the skull with the least muscle and oculomotor artifacts and with the most energy for alpha and delta activities. In somnolence, the cortex does not behave as a whole, which means that different areas show different spectra while getting off to sleep, a fact easy to express by means of the alpha/delta ratio, separately for each of the cranial areas. At sleep onset, the alpha/delta ratio undergoes changes; it is greater than one in wakefulness, less than one in sleep, and in the region of one as the person goes to sleep. In the course of sleep with zero reactivity, the cortex already behaves as a whole, i.e., all cranial areas have similar or the same spectrograms, with the alpha/delta coefficient being less than one all over the skull. At times, the spectrogram taken during mentation (e.g., while undergoing psychological tests) resembles that of somnolence, with the alpha/delta coefficient being greater than one. However, there are differences: in somnolence, the delta activity is increased all over its band, i.e., from 0.5 to 3.5 Hz, while during mentation it is increased solely in the slow delta activity band (0.5 to 3.5 Hz). In somnolence, theta is on the increase, b","PeriodicalId":76514,"journal":{"name":"Sbornik lekarsky","volume":"104 4","pages":"375-85"},"PeriodicalIF":0.0,"publicationDate":"2003-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"24643559","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
