Background and objective. Our main task was to study the ultrastructural organization of the laryngeal mucosa and cartilage on the seventh and fourteenth day of opioid exposure. Methods. The material for the study were mature, outbred male rats in the number of 32 animals, weighing 80g, aged 4.5 months. Animals were injected intramuscularly with Nalbuphine once a day at the same time (10-11 hours in the morning) for 14 days. The initial dose of Nalbuphine was 8 mg / kg during the first week, 15 mg / kg during the second week of the experimental study. Thus, we created the conditions for chronic opioid exposure. Animals were divided into 3 experimental groups: 1 – control group; 2 - animals that received the drug for 7 days; 3 - animals that received the drug for 14 days). All animals were kept in a vivarium. Animal care, labeling and all other manipulations were carried out taking into account the issues of bioethical norms. Before collecting necropsy material, the animal was removed from the experiment with diethyl ether. The the larynx mucosa and rats cartilage were used as the material for ultrastructural examination. Ultrastructural capsule was prepared according to conventional methods. Results. As a result of experimental opioid exposure at the end of 7 days we found alternative changes in the epithelial cells of different parts of the larynx, dyscirculatory changes in blood vessels of lamina propria and submucosa, as well as the destruction of chondrocytes of hyaline and elastic cartilages. The hemocapillaries of lamina propria and submucosa, especially in the ventricles of the larynx and in the subchondral region, were dilated, overflowing with erythrocytes. In the laryngeal mucosa and submucosal base of the laryngeal ventricles, in addition to the overflow of hemocapillaries with erythrocytes, a moderate accumulation of perivascular transudate was noted. At the end of the 14th day of the experimental opioid effect, a pronounced hemocapillaries injury was found, which was accompanied by an increase in the permeability of the vascular wall. In addition to blood plasma, erythrocytes were visualized in the enlarged lumens of hemocapillaries. The development of degenerative changes of endothelial cells, which were accompanied by inhomogeneous dilation of the tubules of the smooth and granular endoplasmic reticulum, was noted. The main substance of the connective tissue of the mucous membrane and submucosal base, especially around the vessels was impregnated with transudate.

Введение. Сосудистые осложнения сахарного диабета (СД) являются одной из ведущих причин повышения смертности пациентов трудоспособного возраста. Предполагается, что индуцированный гипергликемией окислительный стресс и нарушение антиоксидантной защиты играют роль в патологическом механизме повреждения сосудов, частично за счет влияния оксида азота (NО). Цель исследования: уточнение взаимосвязей в системах асимметричного диметиларгинина (АДМА) и NO у пациентов с цереброваскулярными заболеваниями (ЦВЗ) на фоне СД 2-го типа (СД-2). Материалы и методы. Обследованы 72 пациента с ЦВЗ со стенозирующим поражением внутренней сонной артерии вне острого периода: группу 1 составили 39 пациентов (18 мужчин и 21 женщина) с СД-2 в возрасте 65 [58; 72] лет; в группу 2 вошли 33 больных (15 мужчин и 18 женщин) без СД-2 в возрасте 66 [56; 74] лет. Контрольную группу составили 30 добровольцев (16 мужчин и 14 женщин) без проявлений церебральной ишемии и нарушений углеводного обмена, с нормальными значениями индекса массы тела, некурящие, в возрасте 62 [50; 66] лет. Проводилось клиническое обследование, нейро- и ангиовизуализационное исследование, спектр биохимических исследований крови, в том числе определение содержания АДМА и показателей системы NO. Результаты. В группе 1 содержание нитрата, нитрита и NO составило 62,1 [56; 68] мкмоль/л, 48,5 [26; 52] мкмоль/л и 13,6 [9; 23] мкмоль/л соответственно, что достоверно отличалось от значений этих показателей в группе 2 — 58,3 [45; 64] мкмоль/л, 39,6 [26,0; 42,3] мкмоль/л и 18,7 [16,1; 24,7] мкмоль/л соответственно. Отмечен также более высокий уровень AДМА в крови у пациентов с ЦВЗ в сочетании с СД-2 — 0,42 [0,21; 0,53] ммоль/л. Заключение. Обнаружена взаимосвязь между уровнями AДМА и NO при ЦВЗ на фоне СД-2. Это требует продолжения исследований биомаркеров повреждения сосудистой стенки для определения их места в патогенезе ишемических церебральных осложнений СД-2. Background. Vascular complications of diabetes mellitus (DM) are one of the leading causes of increased mortality in patients of employable age. Hyperglycemia-induced oxidative stress and impaired antioxidant protection have been suggested to play a role in the pathological mechanism of vascular damage, in part due to the effects of nitric oxide (NO). Objectives: clarification of relationships in the systems of asymmetric dimethylarginine (ADMA) and NO in patients with cerebrovascular diseases (CVD) and type 2 diabetes (DM-2). Patients/Methods. We examined 72 CVD patients with stenosing lesions of the internal carotid artery outside the acute period: group 1 consisted of 39 patients (18 men and 21 women; 65 [58; 72] years old) with DM-2; group 2 consisted of 33 patients (15 men and 18 women; 66 [56; 74] years old) without DM-2. The control group consisted of 30 volunteers (16 men and 14 women; 62 [50; 66] years old) without manifestations of cerebral ischemia and carbohydrate metabolism disorders, with normal body mass index, non-smokers. A clinical examination, neuro- and angio-imaging study, a spectrum of biochemical blood tests, including the concentration of asymmetric dimethylarginine (ADMA) and indicators of NO system were carried out. Results. In group 1, the content of nitrate, nitrite and NO was 62.1 [56; 68] μmol/l, 48.5 [26; 52] μmol/l and 13.6 [9; 23] μmol/l, respectively, that significantly differed from the content of these parameters in group 2 — 58.3 [45; 64] μmol/l, 39.6 [26.0; 42.3] μmol/l and 18.7 [16.1; 24.7] μmol/l, respectively. Noted also a higher blood level of ADMA in patients with CVD combined with DM-2 — 0.42 [0.21; 0.53] mmol/l. Conclusions. A relationship was found between ADMA and NO levels in CVD patients with DM-2. This requires further studies of biomarkers of vascular wall damage to determine their place in the pathogenesis of ischemic cerebral complications of DM-2.

INTRODUCTIONWe have used an experimental model which allows the evaluation of the qualitative differences in the retinal vascular pattern by means of the labeling of the retine vascular tree with radish peroxidase (HRP) in estreptozotocin-diabetic rats. The aim of the study was to evaluate the effect of ASA and DIP + ASA on the vessels platelet behaviour of said retine pattern in a group of rats in t-hich the diabetes had 3 months of evolution.PROCEDURE22 Wistar male rats were divided into A groups; 1) control group, 2) diabetic rats without antiaggregant, 3) dietetic rats treated with 6 mg/day ASA p.o., 4) diabetic rats treated with 6 mg/day ASA +12 mg/day DIP p.o. For inducing diabetes 30 mg/Kg of i.v. estreptozotocine were administered. The animals were considered “diabetic” when glucemia was over 200 mg/100 ml. After 3 months of treatment with 4IU insuline and ASA, or ASA + DIP, the animals were sacrified. Samples of blood and rings of descending aorta were extracted. Platelet aggregation in IJB in front of 1 μg/ml of collagen and the prostacycline-like activity of the aorta ring were evaluated. The configuration of the retine vascular tree labeled with HRP was observed.RESULTS AND CONCLUSIONSMaximal aggregation intensity: 11.1 Ω in the control group,10.9Ω in the diabetic non-treated group, 4.8Ω in rats receiving ASA and 4.6Ω in rats treated with DIP + ASA. The incUbation during 10 min. of aorta rings in blood samples produced 38.7% inhibition in the control group, 12.8% in the non treated-diabetic group 0% in the ASA group and 49.3% in the group treated with DIP + ASA.The qualitative changes in the diabetic rats retinal vascular network non treated with antiaggregants showed a scarce visibility of capillars as well as large zones of tortuous vessels. The rats treated with ASA showed a continuous vascular bed and less tortuous vessels than the ones in the non treated group but the vascular diameters were smaller than the ones observed in non-diabetic rats; the rats treated with DIP + ASA showed a continuous vascular bed, scarce tortuous vessels and vascular diameters similar to the ones found in non-diabetic rats. Mortality rates: 0% in the control group, 50% in the non-treated diabetic group, 16% in the ASA group and 0% in the DIP + ASA group. The administration of DIP + ASA normalized the prostacycline-like activity and the retinal vascular pattern in estreptozotocin-diabetic rats.

Abstract Background Because of the antioxidant effects of Zataria multiflora (ZM) and carvacrol (CAR) and also the role of oxidative stress in the induction of cardiotoxicity induced by Adriamycin (ADR), the aim of this study was to investigate the improvement effects of ZM extract and CAR on cardiotoxicity induced by ADR in rats. Methods Twenty-eight male rats were randomly assigned to four groups including (1) the control group; (2) the ADR group, which received ADR intravenously at the beginning of the study and the (3) ZM+ADR and (4) CAR+ADR groups, which received ZM and CAR by gavage for 28 consecutive days and ADR as single dose. Blood samples were collected on days 0 and 28 to determine serum glutamic oxaloacetic transaminase (SGOT), serum glutamic pyruvic transaminase (SGPT) and lactate dehydrogenase (LDH). Also, cardiac tissue was removed for redox marker evaluation. Results In the ADR group, malondialdehyde (MDA) significantly increased and superoxide dismutase (SOD) activity and total thiol contents significantly reduced, as compared with the control group, while CAR administration significantly improved this condition. Treatment with ZM significantly increased the SOD activity and total thiol content, as compared with the ADR group. The level of LDH significantly increased on day 28 in the ADR group compared to the control group, and administration of ZM and CAR significantly decreased it. The SGPT and SGOT levels in the ADR group significantly increased, and CAR administration significantly reduced them. Conclusion The results indicate that the administration of ZM hydroalcoholic extracts and its active ingredient, CAR, could reduce the oxidative stress damage through promotion of the cardiac and systemic antioxidant system. Also, CAR administration demonstrated better improvement in cardiotoxicity with ADR in rats.

Submicroscopic studies of the respiratory part of the lungs after 2 and 6 hours after the experimental acute lung injury with hydrochloric acid established adaptive-compensatory and destructive changes in the components of the air-blood barrier.The aim of the study – to learn submicroscopic changes in the components of the air-blood barrier of the lungs in the early period after acute lung injury.Materials and Methods. The experiments were carried out on 30 white mature non-linear male rats weighing 200–220 g. The animals were divided into 3 groups: 1 – control group, 2 – hydrochloric acid damage after 2 hours, 3 – hydrochloric acid damage after 6 hour.Results and Discussion. In an experiment on mature white rats, a study was made of the submicroscopic state of the components of the air-blood barrier in the early periods after acute lung injury. It has been established that adaptive-compensatory and initial destructive changes of the alveolar epithelium and the walls of the hemocapillary take place at 2 o'clock in the experiment. The cytoplasm of respiratory epitheliocytes during this period of the experiment was focal-edematous and enlightened, organelles were destructively altered. For alveolocytes of type I, there was a significant swelling and clarification of the cytoplasm. During this period of the experiment, an increased number of actively phagocytizing macrophages appeared, which acquired a rounded shape, clearly contoured membranes of the cariolema, their invaginations were determined, and in the karyoplasm euchromatin predominated. In alveolocytes of type II, after 6 hours, the progression of destructive changes was established. For which there were peculiarity hypertrophied nuclei with deep invagination of the cariolema, in which there were few nuclear pores, locally expanded perinuclear space. In the edematous cytoplasm, organelles were found to be destructively altered.Conclusions. Acute damage to the lungs leads to a disruption of the ultrastructural organization of the air-blood barrier. Established adaptive-compensatory processes and signs of destructive changes in the alveolar epithelium and the walls of hemocapillaries, which leads to deterioration of gas-exchange processes in the lungs.

Introduction: Recently, the consequence of chemical industries and noise on human health is the update subject for researchers. There are many reports published about nephrotoxicity of noise and cadmium alone. Objectives: The main aim of this study was to detect the combined consequence of noise and cadmium on renal function. Materials and Methods: Forty adult male rats were put into eight groups in random order (n=5). Groups 1 control, group 2 exposed to 90 dB (decibels) noise, groups 3- 5 received (intraperitoneal; ip) cadmium chloride (CdCl2) at doses of 1,2,3 mg/kg and group 6-8 pretreated with CdCl2 at doses of 1, 2, and 3 mg/kg 30 minutes before exposing to 90 dB noise. The exercise was repeated for seven consecutive days. Animals were killed 24 hours afterwards. Blood urea nitrogen (BUN) and creatinine (Cr) levels were analyzed. Kidney tissues were excised for measuring malondialdehyde (MDA) and glutathione (GSH) concentrations. Results: There was significant rise on the levels of BUN, Cr and MDA. Additionally, a decrease on the level of GSH in rats that were exposed to noise or cadmium alone or combined to noise and cadmium was detected. Significant elevation of BUN, Cr, MDA and depletion of GSH were also noted in cadmium-treated rats compared to those in the animals co-exposed to cadmium and noise. Conclusion: This study shows that exposed rats to cadmium and/or noise caused renal function impairment. Production of oxidative stress is responsible for cadmium or noise induced nephrotoxicity. However, co-exposure of cadmium and noise reduced nephrotoxicity of cadmium. The possible explanation for noises suppressing cadmium nephrotoxicity is that noise may enhance excretion and/or induced redistribution and depleted accumulation of cadmium in the kidney.

Objectives: The present study aimed to investigate the antioxidant activity of cerium oxide nanoparticles (CeNPs) against paraquat (PQ)-induced liver injury in rats. Methods: Thirty-two male rats were divided into four 8-member groups and treated intraperitoneally with PQ and/or CeNPs for 14 days. Group 1 received PQ (5 mg/kg/d), group 2 received CeNPs (15, 30, and 60 mg/kg/d), group 3 received a combination of PQ (5 mg/kg/d) and CeNPs (15, 30, and 60 mg/kg/d), and group 4 (control group) received saline solution. Serum samples along with liver tissue samples were collected from all the rats. Oxidative stress (OS) biomarkers including total antioxidant capacity, lipid peroxidation, total thiol groups, DNA damage, and nitric oxide levels were determined. Histological samples were also analyzed using hematoxylin and eosin staining slides. Results: Levels of oxidative stress and hepatic tissue damage were significantly higher in the PQ group compared to the control group. CeNPs at a dose of 15 mg/kg showed the antioxidant activity and compromised the PQ-induced damage. Conclusion: In the scenario tested in this study, CeNPs could reduce the levels of OS, as well as hepatic damage induced by PQ.

Purpose. The aim of the study is to examine the possible therapeutic effects of a known cardiac glycoside, digoxin, on a rat model of MTX-induced hepatotoxicity. Methods. The study was conducted on twenty-four male rats. While eighteen rats received a single dose of 20 mg/kg MTX to obtain an injured liver model, six rats constituted the control group. Also, the eighteen liver toxicity model created rats were equally divided into two groups, one of which received digoxin 0.1 mg/kg/day digoxin (Group 1) and the other group (Group 2) was given saline (% 0.9NaCl) with a dose of 1 ml/kg/day for ten days. Following the trial, the rats were sacrificed to harvest blood and liver tissue samples to determine blood and tissue MDA, serum ALT, plasma TNF-α, TGF-β, IL-6, IL-1-Beta, and PTX3 levels. Results. MTX’s structural and functional hepatotoxicity was observable and evidenced by relatively worse histopathological scores and increased biochemical marker levels. Digoxin treatment significantly reduced the liver enzyme ALT, plasma TNF-α, TGF-β, PTX3, and MDA levels and decreased histological changes in the liver tissue with MTX-induced hepatotoxicity in the rat model. Conclusion. We suggest that digoxin has an anti-inflammatory and antihepatotoxic effect on the MTX-induced liver injury model.
