LIPID PEROXIDATION IN MULTIPLE ORGAN FAILURE CAUSED BY ASSOCIATED CHEST AND HIP TRAUMA

Background. The injured with polytrauma are classified as extremely severe patients, as their emergency care and intensive care is followed by significant difficulties, frequent development of complications, high mortality and survivors disability. Objective. This study is aimed to evaluate the effect of lipid peroxidation in heart, lungs, liver and blood of rats in early and late periods of combined traumatic injury of chest and hips and to establish their influence on the development of multiple organ failure. Methods. The study was conducted on 70 adult male white nonlinear rats. It was determined the content of lipid hydroperoxides and concentration of TBA-active products in erythrocyte mass, heart, lungs and liver. Results. The data prove activation of free radical oxidation at the first day of post-traumatic period. Analysis of the data evidences the increase in of lipid hydroperoxides (HPL) rate in liver homogenate in group E1 in 1.5 times, in all subsequent periods of the research the increase in rate fluctuated within 1.9-2.0 times. In blood and heart the HPL rate increased twice in group E1, reached maximum in group E2 and gradually decreased till the end of the experiment, data exceeded the control group. The highest level of HPL was determined in lung tissues (r≤0.01). In the post traumatic period the highest TBA-AP was detected in lungs and liver. Conclusions. In case of simulated trauma (injury of chest with fractures of both hips) hyperactivation processes of free radical oxidation is observed in 1 day, reaching a peak in 7-14 days of post-traumatic period in blood, tissues, liver, heart and lungs if compared to the control group causing multiple organ failure

MORPHOLOGICAL CHANGES IN LUNGS, HEART AND LIVER CAUSED BY EXPERIMENTAL ASSOCIATED CHEST AND THIGHS TRAUMA

Background. According to preliminary results obtained, the development of hypoxemia caused by chest trauma affected lipid peroxidation stimulation leading to disruption of cell membranes structure and consequently cell death closing the ‘vicious’ circle, which in our opinion and according to the literature cause multiple organ failure.Objective. The aim of our study was to determine the features of morphological changes in cases of heart, lungs, liver injury after associated chest and both thighs trauma in rats.Methods. For histological examination the pieces of left ventricle tissues of heart, lungs and liver were used, which were fixed in 10% neutral formalin solution, dehydrated and embedded in paraffin blocks.Results. It was established that associated trauma of chest and both thighs in 1 day after the injury is accompanied by disturbances of hemodynamics in parenchymal organs due to venous congestion that occurs during the development of cardiovascular disease caused by traumatic shock. In the most severe period of maximum likelihood of complications, within 3 days, respiratory hypoxia, cardiovascular disorders, metabolic acidosis, and induced programmed cell death may develop.Conclusions. On the background of increasing pulmonary oedema (thickening of inter air sac membranes) caused by associated trauma of chest and both thighs in rats after only one day of the experiment hemodynamic changes in heart (low-blood supply of vessels in epicardium and isolated blood vessels of venous type) and liver (mainly plethora of blood vessels) were observed, which lead to morphological changes of myocardium within 3 days

АНАЛІЗ ГОРМОНАЛЬНИХ ЗМІН В ОРГАНІЗМІ ЖІНОК ІЗ ФОНОВИМИ І ПЕРЕДРАКОВИМИ ПРОЦЕСАМИ ШИЙКИ МАТКИ

Мета дослідження – оцінити особливості перебігу захворювань шийки матки залежно від гормональних порушень. Матеріали та методи. Відповідно до мети дослідження, під нашим спостереженням перебували 105 жінок віком від 18 до 42 років. Середній вік обстежених становив (25,92±0,61) року. Критеріями для включення пацієнток у дослідження були патологічні процеси шийки матки і порушення менструального циклу. Усім жінкам проводили загальноклінічне обстеження, передбачене наказом МОЗ України від 31.12.2004 року № 676 (огляд шийки матки в дзеркалі, мікроскопія мазків з піхви, Pap-тест, кольпоскопія і, при потребі, біопсія шийки матки), а також додаткові клініко-лабораторні методи обстеження: виявлення ВПЛ методом ПЛР у зскрібку з цервікального каналу та гормональні обстеження (визначення рівнів дигідротестостерону, пролактину, андростендіолу-глюкороніду, 17-кетостероїдів, індексу вільного тестостерону, рівнів фолікулостимулюючого гормону, лютеїнізуючого гормону, естрадіолу (Е2), дигідроепіандростерону-сульфату на 2–3 день та на 21–22 дні менструального циклу). Результати дослідження та їх обговорення. При дослідженні гормональних показників у жінок обстежуваних груп до проведеного лікування було виявлено підвищення рівнів андрогенів вище референтних значень загалом у 14 (35,0 %) пацієнток 1 групи і у 23 (57,5 %) – 2 групи. Зниження рівня прогестерону спостерігалося в 11 (27,5 %) жінок 1 групи і 15 (37,5 %) – 2 групи. Підвищення естрогенів було відмічено у 5 (12,5 %) пацієнток 1 групи і 4 (10,0 %) – 2 групи. Висновок. При аналізі проведених досліджень були виявлені такі варіанти гормональних порушень у пацієнток із захворюваннями шийки матки: – НЛФ була характерна для 65 % пацієнток; – СПКЯ був характерний для 22,5 % хворих; – ГГН було виявлено у 5,0 % жінок
