The purpose of the study was to determine and evaluate the features of morphological changes in the liver parenchyma of 5-month-old white outbred rats under the influence of anti inflammatory drugs under conditions of polypharmacy.
The object of study for experimental studies was taken 250 white male rats weighing 200-250 g.
The scientific novelty of the research is as follows: polypharmacy of anti-inflammatory drugs negatively affects all parameters of liver structures. Under the influence of polypharmacy, there is a decrease in the absolute mass of the liver, volume and morphological parameters of the liver parenchyma. The decrease in morphometric parameters depends on the number of drugs in polypharmacy; under conditions of polypharmacy, the state of the hepatic capillaries and internal bile ducts, as well as biological membranes, was studied, as a result of which the structural structure of the liver, the development of destruction of the hepatic tissue were studied, and the morphofunctional foundations of this condition were shown.
Implementation of the research results. Based on the obtained scientific results, the morphofunctional characteristics of the liver of rats in the norm and under the influence of polypharmacy were determined:
Approved methodological recommendations: "Methodology for determining the morphometric parameters of the liver during polypharmacy of anti-inflammatory drugs" (Conclusion No. 8n-r / 265 dated 14.03.2022 of the Ministry of Health of the Republic of Uzbekistan) and "Methodology for determining the morphometric parameters of the liver during polypharmacy of anti-inflammatory drugs" (Uzbekistan, Conclusion of the Ministry of Health of the Republic of Uzbekistan No. 8 n-z 180 of 2022), electronic program No. DGU 1038 "Program for studying the comparative characteristics of morphological changes caused by polypharmacy in the liver."
The scientific results obtained in the study of morphological and functional properties and morphometric changes in the structure of the liver under the influence of polypharmacy have been introduced into the practice of the Samarkand branch of the Republican Specialized Oncological and Radiological Scientific and Practical Medical Center of the Samarkand City Medical Association (Order of the Ministry of Health of the Republic of Uzbekistan dated March 14, 2022, 8n-r / 265-No. and conclusion No. 8 n-z 180 of 2022). The implementation of the obtained research data allows developing methods for early diagnosis, treatment and prediction of organopathology by morphological parameters, improving the quality of life and reducing the number of complications.
The structure and scope of the dissertation. The structure of the dissertation consists of an introduction, three chapters, a conclusion and a list of references. The volume of the dissertation was 103 pages.
Objects of research: 92 immature rats with term of 30-40 days. 108 patients with asiderotic an anemia: men - 13 (12%), women - 95 (88%); middle age - 39,9 years. The control group was made by 17 healthy persons.
The purpose of work: Increase of efficiency of treatment of patients asiderotic [iron-deficiency] anemia by an induction of synthesis and a metabolism a theme in a liver.
Methods of research: clinical, biochemical, morphological, tool.
The received results and their novelty: Activization of the initial stages of synthesis is established on models alimentary asiderotic [iron-deficiency] anemia in mitochondrial and microsomal-cytosol fractions of a liver a theme, on a background to inhibit its final stage. Correction of a level malonic dialdehyde and activity of enzymes superoxide dismutase (SOD) and catalase (CAT) is revealed as a result of application of a combination of preparations maltofcr and neosclcn in mitochondrial and microsomal-cytosol fractions of a liver of experimental animals. For the first time we analyse parameters of ions of tri valent, bivalent iron both dif-feritin in mitochondrial and microsomal-cytosol fractions of a liver of experimental animals. The morphological picture of a liver at alimentary iron deficiency is submitted an anemia and correction of the revealed infringements by preparations maltofcr and ncosclcn. For the first time on the big clinico-expcrimcntal material efficiency of application of a combination of preparations maltofer and neoselen is shown.
The practical importance: Application of a combination of preparations maltofer and neoselen on a clinico-experimental material restores activity of enzymes of synthesis and disintegration a theme in hepatocyte’s, improves ferroki-nctic, hematologic parameters and promotes improvement of a functional condition of a liver. The received positive results in clinical researches have found acknowledgement (confirmation) on an experimental material that allows to recommend the given circuit of treatment железодефицитной to an anemia in clinical and outpatient conditions.
Degree of introduction and economic efficiency: Results of research are introduced into practice гематологического, therapeutic branches, and as for doctors of an initial link.
Scope: hematology, therapy.
В проблеме региональной патологии Средней Азии, в частности Узбекистана, инфекционно-аллергические и токсические гепатиты и циррозы занимают одно из центральных мест. Признавая большую этиологическую роль вирусов в развитии гепатита нельзя не отметить, что значение токсических поражений печени в генезе прогрессирования хронических гепатитов и циррозов печени в последнее время резко возросло. При токсическом поражении печени, сопровождающемся последующим диффузным поражением гепатоцитов в связи с ишемией печени, происходят серьёзные нарушения обмена веществ, в частности белкового обмена. Активное изучение биосинтеза белков и нуклеиновых кислот при патологических состояниях и заболеваниях представляет огромный интерес, так как именно эти процессы в первую очередь характеризуют степень и глубину функциональных нарушений, определяют уровень репаративных процессов в органах и тканях
The aim of study was to research the effect of darmonal and phytin compounds on the amount of glycogen and lactic acid in the liver tissues.
Materials and methods. The new compounds of phytin-C were studied: phytin-C, cobalt phytate and patent substance of darmonal obtained from wheat grain cells grown under special conditions. For comparison, the bioflavonoid of plant origin Liv-52, being used in treatment of liver diseases, was also studied. The study was carried out on 60 white rats weighing 120-150 g. The toxic hepatitis was caused by subcutaneous administration of 50% carbon tetrachlormetan oil solution in dose 0.8 ml/100 g for 4 days.
Results. The results showed that the combined introduction of extract significantly enlarged the outcome at joint use drug Liv-52 in animals, and, especially such effect was noticeable with addition phytin-C. The use bioactive substance in combination with complex phytin compound was more effective for accumulation of glycogen in the liver than using the drugs separately, hepatotoxin - carbon tetrachlormetan reduced carbohydrate metabolism and led to increase glycogen in liver tissues as well as the decreased lactic acid. It was determined that the combined treatment was more effective at toxic hepatitis induced by carbon tetrachlormetan, it had the hepatoprotective effect and improved liver function.
В последние десятилетия отмечается неуклонный рост болезней печени. Прогнозы темпов роста этих патологий неутешительны: предполагается, что на фоне сохраняющейся химизации и загрязнения внешней среды в ближайшие десятилетия следует ожидать увеличения заболеваемости гепатитами и циррозами печени еще на 30 50%. По данным ВОЗ, частота токсических поражений печени с 1960 г. увеличилась в мире в 6 8 раз.
В последние годы внимание исследователей всё больше привлекает проблема коморбидности, под которой понимают сочетание у одного больного нескольких хронических заболеваний. Следует подчеркнуть, что влияние коморбидной патологии на клинические проявления, диагностику, прогноз и лечение многих заболеваний многогранно и индивидуально. В последние годы еще одним признанным компонентом МС является неалкогольная жировая болезнь печени (НАЖБП). НАЖБП охватывает спектр состояний от стеатоза печени до цирроза печени и гепатоцеллюлярной карциномы. Результаты последних исследований подтверждают гипотезу о том, что НАЖБП приводит к более высокому риску сердечно-сосудистых заболеваний независимо от других прогностических факторов риска.
