<p>Research results have shown the liver damage in terms of EP and IS in violation of its functional state. High<br />levels of bilirubin and cholesterol suggests the existence of violation of integrity hepatocytes syndrome which is<br />caused by the negative impact of VC in terms of IS . Using the domestic drug “Corvitin”, resulted in a significant<br />decrease in the changed parameters of bilirubin and cholesterol under conditions of formation of EP and IP , indicating<br />its positive effect adjustment.</p>

Until now, chronic generalized periodontitis (CGP) has been a severe and common pathology of periodontal tissues. It is characterized by a prolonged course of a disease with periods of remission and relapse. CGP can often cause a significant dysfunction of the dentition, loss of the retaining dental apparatus and tooth loss. Local inflammatory phenomena certainly depend on changes in homeostasis at the body level. There is no doubt, that successful treatment of this severe periodontal disease is possible not only in case of local treatment, but also in case of remodeling at the body level. In this regard, systemic changes in homeostasis are of great importance, in particular information on the structural and functional state of red blood cells. The aim of the paper was to study the structural and functional state of red blood cells in various forms of CGP. Materials and Methods. The study involved 60 patients with mild CGP (n=32) and moderate CGP (n=28); the patients suffered from the disease for 5 to 15 years. The authors conducted a comprehensive examination of patients using clinical, laboratory and radiological diagnostic techniques. They also estimated structural and functional states of periodontal tissues according to various indices; erythrocytes were estimated according to the phospholipid composition of biomembranes, the level of primary and secondary products of lipid peroxidation, activity of catalase, superoxide dismutase, and phospholipase A2. Results. It has been established that inflammatory phenomena in periodontal tissues with CGP are accompanied by significant changes in the lipid metabolism of red blood cells and the dysfunction development. The severity of functional and metabolic changes in these blood elements correlates with the disease severity. Conclusion. The results are of particular importance as a separate component of chronic periodontitis pathogenesis. Chronic periodontitis is one of the initiators of the pathological reaction cascade leading to the formation of microcirculatory disorders and the occurrence of hemic and circulatory hypoxia, which is a universal link in the pathogenesis chain of any pathological process and a central problem of somatic pathology. Keywords: chronic periodontitis, red blood cells, lipid metabolism. До настоящего времени тяжелой и распространенной патологией тканей пародонта является хронический генерализованный пародонтит (ХГП), который характеризуется длительным течением с периодами ремиссий и рецидивов, часто приводит к существенной дисфункции зубочелюстной системы, утрате удерживающего аппарата зубов и потере последних. Безусловно, местные воспалительные явления во многом зависят от изменений гомеостаза на организменном уровне. Не вызывает сомнений факт, что успешная терапия этой тяжелой болезни пародонта возможна не только при местном лечении, но и при коррекции изменений на организменном уровне. В связи с этим важны сведения о системных изменениях гомеостаза, в частности о структурно-функциональном состоянии эритроцитов. Целью исследования явилось изучение структурно-функционального состояния эритроцитов при различной тяжести ХГП. Материалы и методы. В исследовании приняли участие 60 пациентов с ХГП легкой (n=32) и средней (n=28) степеней тяжести и продолжительностью заболевания от 5 до 15 лет. Проведено комплексное обследование больных с использованием клинико-лабораторных и рентгенологического методов исследования. Выполнена оценка структурно-функционального состояния тканей пародонта по различным индексам; эритроцитов – по фосфолипидному составу биомембран, уровню первичных и вторичных продуктов липопероксидации, активности каталазы, супероксиддисмутазы, фосфолипазы А2. Результаты. Установлено, что воспалительные явления в тканях пародонта при ХГП сопровождаются значительными изменениями липидного метаболизма эритроцитов с развитием дисфункциональных явлений. Выраженность функционально-метаболических изменений этих элементов крови коррелирует с тяжестью заболевания. Выводы. Выявленный факт представляет особую значимость как отдельный компонент патогенеза хронического пародонтита – одного из инициаторов каскада патологических реакций, приводящих к формированию микроциркуляторных расстройств и возникновению гемической и циркуляторной гипоксии, которая является универсальным звеном цепи патогенеза любого патологического процесса и центральной проблемой соматической патологии. Ключевые слова: хронический пародонтит, эритроциты, липидный метаболизм.

The article presents current information on the pathogenetic role of lipid metabolism disorders and the value of lipotoxicity in renal pathology, contributing to the progression of nephropathy. The detected increase in cholesterol level, TAG, LDL, decrease in plasma HDL concentration in chronic kidney disease (CKD) is accompanied by significant changes in the composition of various lipoproteins caused by changes in the expression and activity of key proteins and enzymes involved in the biosynthesis, transport, remodeling and catabolism of lipids and lipoproteins. It has been proven that dyslipidemia in CKD affects the morphological and functional state of the kidneys, contributing to the development of renal lipotoxicity processes, affecting the structural and functional state of the kidneys, initiating oxidative stress, systemic inflammation, vascular damage, and dysregulation. To date, research on the significance of dyslipidemia as a pathogenetic factor in the formation of chronic kidney disease remains insufficiently studied. Dysregulation of lipid metabolism, leading to dyslipidemia, is often an undervalued complication of CKD.

In this study, experimental data on the biological action of glyproline peptides — Pro-Gly-Pro, Pro-ArgPro, Arg-Pro-Gly-Pro and Pro-Gly-Pro-Leu — on the processes of blood coagulation and lipid metabolism were obtained using animal models of metabolic syndrome. Under the conditions of increased blood clotting and hypercholesterolemia, the regulatory peptides under study were administered intranasally for 7 days once every 24 hours. 20 hours after the last peptide administration, thromboelastogram parameters confi rmed the restoration of the functional state of the coagulating and anticoagulant systems. In addition, a simultaneous positive shift in the parameters of lipid metabolism was observed. These changes lasted for 7 days following the withdrawal of the drugs. It is found that the biological action of the peptides under study consists in their simultaneous regulatory impact on the processes of hemostasis and lipid metabolism.

This cytochemical study was designed to investigate early metabolic changes in the aortic wall that might lead to or accompany development of atherosclerotic plaques in rabbits. The hypothesis that the primary cellular alteration leading to plaque formation might be due to changes in either carbohydrate or lipid metabolism led to histochemical studies that showed elevation of G-6-Pase in atherosclerotic plaques of rabbit aorta. This observation initiated the present investigation to determine how early in plaque formation and in which cells this change could be observed.Male New Zealand white rabbits of approximately 2000 kg consumed normal diets or diets containing 0.25 or 1.0 gm of cholesterol per day for 10, 50 and 90 days. Aortas were injected jin situ with glutaraldehyde fixative and dissected out. The plaques were identified, isolated, minced and fixed for not more than 10 minutes. Incubation and postfixation proceeded as described by Leskes and co-workers.
