Markers of aging known today do not clearly define the biological age of the organism, which creates the need for their further search. The oral fluid is a convenient object for such studies, since it contains proteins whose conformation corresponds to the age of the organism. The method developed by the authors allows, by transferring biological fluids into a solid phase, to transform the structure of the molecular-level components dissolved in them to a level accessible to visual analysis. The aim of the study is to search for markers of biological age in the solid-phase structures of the oral fluid. Materials and methods. The structures of the solid phase oral fluid of 240 people with a sanitized oral cavity were studied. There are four age groups of 60 patients each: middle age; elderly; senile and long-livers. Oral fluid was taken in the morning on an empty stomach. The method of cuneiform dehydration of biological fluids was used. Dehydration of drops of oral fluid was carried out on special test cards under standard conditions. As a result, dry films (facies) were obtained, the structural features of which were examined by microscopy. Results. The structure of oral fluid facies is determined by the ratio of salt and organic substances present in it. During the formation of a facies, salts bind to proteins that have an abnormal conformation. In middle-aged patients, the facies have a clear division into saline and marginal (protein) zones. With age (elderly and senile age), due to the increased activity of catabolic processes, in the facies of the oral fluid, an increasing area is occupied by organic substances, and the areas occupied by salts decrease, while the facies lose their physiological structuring. At the same time, the facies of the oral fluid of most long-livers retain a structure similar to the facies of middle-aged representatives. Conclusions. The biological age of the organism is determined by the level of its autointoxication by proteins with pathological conformation. Autotoxins are contained in the oral fluid and are manifested in the structure of its facies. Due to natural age-related metabolic shifts towards an increase in catabolic processes, the protective systems that block autointoxication by metabolites cease to provide their complete neutralization, which is reflected in the facies structure. Facies of the oral fluid of long-livers have a fundamentally different structure compared with the facies of the elderly and senile persons, indicating a low degree of autointoxication of the organism of long-livers, which determines a longer life span. Thus, specific solid phase structures of oral fluid facies can be used as objective markers of biological age.
The authors examined the composition of biocrystalline structures (anisomorphones) of blood serum in patients with laryngeal cancer. Such structures are formed when blood serum becomes solid, i.e. during its marginal dehydration. The revealed anisomorphones represent three types of marker structures: a marker of a malignant tumor active growth (the aggregation of macroferolite and granular microspherolite with the same degree of anisotropy); a marker of a degenerative-dystrophic process (the aggregation of a macrospherolite with a low degree of anisotropy and microspherolite with a high degree of anisotropy); a marker of a malignant growth progression (a wavy microspherolite without aggregation). The aim of the study is to identify diagnostic markers of the malignant process activity in the solid phase structures of the blood serum in patients with laryngeal cancer and to assess their importance for choosing an effective therapy. Materials and Methods. Marginal dehydration of blood serum was used as the main research method. It is a part of the "Litos-system" diagnostic technology (Marketing authorization FS No. 155, of 2009). Results. It has been shown that the developmental phase of laryngeal cancer (active growth or degenerative-dystrophic process) is an important criterion for choosing treatment options. Surgical treatment is the most effective during the degenerative-dystrophic tumor process, while radiation therapy is preferable during the active phase of malignant growth. Key words: laryngeal cancer, blood serum, marginal dehydration of biological fluids, markers of tumor growth activity. Исследован состав биокристаллических структур (анизоморфонов) сыворотки крови больных раком гортани, которые формируются при переходе сыворотки крови в твердую фазу в процессе ее краевой дегидратации. Выявленные анизоморфоны представляют собой три вида маркерных структур: маркер активного роста злокачественной опухоли – агрегация макросферолита и зернистого микросферолита с одинаковой степенью анизотропии; маркер дегенеративно-дистрофического процесса – агрегация макросферолита с низкой степенью анизотропии и микросферолита с высокой степенью анизотропии; маркер прогрессии злокачественного роста – волнистый микросферолит вне агрегации. Цель – выявить диагностические маркеры активности злокачественного процесса в структурах твердой фазы сыворотки крови больных раком гортани и оценить их значение для выбора эффективного вида лечения. Материалы и методы. В качестве основного метода исследования использован метод краевой дегидратации сыворотки крови, являющийся разделом диагностической технологии «Литос-система» (Разрешение ФС № 155 от 2009 г. на применение в клинической практике). Результаты. Показано, что фаза развития рака гортани (активный рост или дегенеративно-дистрофический процесс) служит важным критерием выбора вида лечения: в фазу дегенеративно-дистрофического процесса опухоли наиболее благоприятный эффект дает хирургическое лечение, а в период активной фазы злокачественного роста – лучевая терапия. Ключевые слова: рак гортани, сыворотка крови, краевая дегидратация биологических жидкостей, маркеры фазы активности опухолевого роста.
