The goal of the studies is reproduction on experimental model of a number of pathologies (in vivo and in vitro) of the `sensitization to laser radiation by staining' effect. Testing of the histochemical stains as sensitizers to laser irradiation of their `address substrates', i.e. vitally stained intracellular structures which participate in the pathologic processes evolution is under planning. The processes include: (a) metabolic disorders in the brain cells, i.e. disseminated sclerosis; (b) generalized metabolic disorders- -mucopolysaccharidosis and collagenosises (periarteritis nodosa, rheumatism, rheumatoid arthritis, sclerodermia); (3) metabolic disorders in individual organs--vessel atherosclerosis, hypercholesterolemia, myocardial infarction, cardiosclerosis, caries and parodontosis. The conditions of the studies are detailed in the recommendations along the positions: (1) disease name; (2) disease characteristics: (a) pathomorphologic, (b) biochemical; (3) stains revealing the disease signs and recommended for testing; (4) `address substrates' of the stains that are targets for laser radiation; (5) lasers recommended for the testing after the cells staining in vivo in the corresponding pathology; (6) experimental models of the pathologies suggested for the testing; (7) criteria of the stain efficiency as target sensitizer to the laser light (criteria of the `laser sensitization by staining' efficiency). Possible perspectives for the experimental clinical medicine are indicated of common histochemical stains and lasers use and of practice introduction of the `laser histochemical surgery' in the case the described concept is confirmed in experiments and clinically.","PeriodicalId":219206,"journal":{"name":"Current Research on Laser Use in Oncology","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1999-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120959727","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}

Given the large number of exposed population, screening is considered to be the most expedient method to organize medical observation of exposed persons. As was shown by the results of medical examinations conducted for 1 391 residents of the Techa riverside villages, laser correlation spectrometry (LCS) of blood plasma has proved to be a highly effective screening method for early (pre-clinical) detection of malignant neoplasms and pre-cancerous conditions. It was established that LC- spectra of blood plasma in persons with cancer and pre- cancer can easily be differentiated from non-cancer conditions. Of particular diagnostic significance is the high-frequency range of the spectrum. The development of a diagnostic algorithm has allowed to carry out a computer- based classification of blood plasma LC spectra as a component of exposed population health monitoring system.","PeriodicalId":219206,"journal":{"name":"Current Research on Laser Use in Oncology","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1999-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115620888","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}

The patients' aged varied from 33 to 62 years. For the first time we made intraoperative laser autofluorescent spectroscopy (IOLAS). The laser ve1ength was 632.8 nm. We defined a autofluorescent intensity. Portable equipment was used. The duration of the procedure did not exceed 2mm. The autofluorescent peak of adrenal tissue was 1.33±0.05 relativistic unit (RU) at 685 nm. The autofiurescent peaks of adrenal adenomas were 1 .07 RU, 0.9-1 .15 RU, 1.7-1 .9 RU, 3.4 RU accordingly for trabecular adenoma, lightcellular adenoma, mixedcellular adenoma, darkcellular adenoma Besides greater contribution of longwave component to auflurescence is characteristic for mixecellular adenoma and especially for darkcellular adenoma. The autofiurescent peaks of aldosteroma and pheochromocytoma were accordingly 1.2-1.4 RU and 2.2 RU. Spectral distribution of intensity was like mixedcellular adenoma's one. In the case of malignant lymphoma the autofiurescence peak was 2,3 RU and we also noted displacement of maximum of autoflurescence (-15 nm, from 685 nm to 670 nm).The results of IOLAS application as a adjuvant diagnosticmethod point to promise for intraoperative rapid diagnostics of adrenal tumours.","PeriodicalId":219206,"journal":{"name":"Current Research on Laser Use in Oncology","volume":"77 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1999-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124519182","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}
