Article | 2017 | Bratislava Medical Journal118 ( 8 ) , pp.495 - 498

PURPOSE: To evaluate the neutrophil-to-lymphocyte ratio (NLR) levels to predict the severity of inflammation in thyroid ophthalmopathy (TO). METHODS: Fifty-six patients with TO and 40 healthy subjects were included in this study. TO patients were divided into two groups according to clinical activity score (CAS). Group 1 included 24 active TO patients and Group 2 included 32 inactive TO patients. The thyroid status, white blood cell (WBC), neutrophil, and lymphocyte counts were performed. NLR was calculated by dividing the neutrophil count by the lymphocyte count. RESULTS: The mean age was 53.6 ± 5.4 in active TO group, 54.2 ± 5.6 i . . .n inactive TO group, and 52.7 ± 5.2 in the control group. The WBC, neutrophil, lymphocyte and NLR levels were higher in patients with TO than in the control group (p < 0.05). A significant difference in NLR was found between the inactive and active TO groups (p < 0.05). CONCLUSION: NLR values were found to be higher in patients with TO than in controls. NLRvalues were also found higher in active TO patients than in inactive TO patients Daha fazlası Daha az

Conference Object | 2012 | Journal of Surgical Research178 ( 1 ) , pp.424 - 430

Background: We assessed the effects of dexmedetomidine in a rat model of ?-naphthylthiourea (ANTU)-induced acute lung injury. Methods: Forty Wistar Albino male rats weighing 200-240 g were divided into 5 groups (n = 8 each), including a control group. Thus, there were one ANTU group and three dexmedetomidine groups (10-, 50-, and 100-µg/kg treatment groups), plus a control group. The control group provided the normal base values. The rats in the ANTU group were given 10 mg/kg of ANTU intraperitoneally and the three treatment groups received 10, 50, or 100 µg/kg of dexmedetomidine intraperitoneally 30 min before ANTU application. The . . . rat body weight (BW), pleural effusion (PE), and lung weight (LW) of each group were measured 4 h after ANTU administration. The histopathologic changes were evaluated using hematoxylin-eosin staining. Results: The mean PE, LW, LW/BW, and PE/BW measurements in the ANTU group were significantly greater than in the control groups and all dexmedetomidine treatment groups (P < 0.05). There were also significant decreases in the mean PE, LW, LW/BW and PE/BW values in the dexmedetomidine 50-µg/kg group compared with those in the ANTU group (P < 0.01). The inflammation, hemorrhage, and edema scores in the ANTU group were significantly greater than those in the control or dexmedetomidine 50-µg/kg group (P < 0.01). Conclusion: Dexmedetomidine treatment has demonstrated a potential benefit by preventing ANTU-induced acute lung injury in an experimental rat model. Dexmedetomidine could have a potential protective effect on acute lung injury in intensive care patients. © 2012 Elsevier Inc. All rights reserved Daha fazlası Daha az

Article | 2007 | Echocardiography24 ( 7 ) , pp.702 - 711

Aim: This study was designed to assess whether ultrasonic reflectivity, evaluated by integrated backscatter analysis was associated with the severity of inflammation and diastolic dysfunction of the left (LV) and right ventricles (RV) in Behçet's disease (BD). Methods: The study consisted of 20 patients with BD and 18 healthy controls. The expression of CD11b and CD63 on the surface of granulocytes and monocytes were measured by flow cytometry. RV and LV diastolic functions were assessed by tricuspid and mitral annular tissue Doppler recordings, respectively. Backscatter cyclic variation (CV) and maximal intensity (IB) were measured . . . in RV lateral wall, interventricular septum, and posterior LV wall from parasternal long-axis view, apex from apical four-chamber view, anterior, inferior, and lateral LV walls from parasternal short axis view. Results: The mean fluorescence intensity (MFI) of CD11b on granulocytes and CD63 on monocytes in BD patients was higher than those of controls. Patients with BD had smaller mitral and tricuspid annular early diastolic wave velocities and early/late diastolic wave velocity ratios (E/A) than controls. MFI of CD11b and CD63 was inversely correlated with tricuspid and mitral annular E/A in BD patients. CV of RV and global CV of LV were found to be diminished in BD patients than controls. CV of RV and global CV of LV showed a direct correlation with tricuspid and mitral annular E/A ratio, respectively. Conclusion: There is an association between the levels of cellular adhesion molecules, deterioration of diastolic function, and altered myocardial ultrasonic reflectivity in BD. © 2007, the Authors Daha fazlası Daha az

Article | 2016 | Journal of Reproductive Immunology116 , pp.98 - 103

The aim of this study is to examine women with polycystic ovary syndrome (PCOS) to determine the relationship between xanthine oxidase (XO) and oxidative stress, inflammatory status, and various clinical and biochemical parameters. In this cross-sectional study a total of 83 women including 45 PCOS patients and 38 healthy women were enrolled. We collected blood samples for XO and superoxide dismutase (SOD) activity, hormone levels, cholesterol values, and inflammatory markers. Body mass index (BMI) , waist-to-hip ratio (WHR), and blood pressure were assessed. Blood samples were taken for hormonal levels, cholesterol levels, fasting . . .plasma glucose (FPG), fasting plasma insulin (FPI), homeostatic model assessment-insulin resistance (HOMA-IR) index, quantitative insulin sensitivity check index (QUICKI), C-reactive protein (CRP), white blood cell and neutrophil counts, XO and SOD activities. The basal hormone levels, triglyceride (TG) levels, TG/HDL-C (high density lipoprotein-cholesterol) ratios FPG, FPI and HOMA-IR levels were higher in PCOS patients compared to controls (p < 0.05). Platelet and plateletcrit (PCT) values, CRP, and XO activity were significantly increased, however SOD activity was decreased in PCOS patients (p < 0.001). XO activity was positively correlated with LH/FSH and TG/HDL ratios, CRP, PCT, FPG, FPI, and HOMA-IR, and negatively correlated with QUICKI levels. In conclusion, XO is a useful marker to assess oxidative stress in PCOS patients. Positive correlations between XO and inflammatory markers and cardiovascular disease risk factors suggest that XO plays an important role in the pathogenesis of PCOS and its metabolic complications. © 2016 Daha fazlası Daha az

Role of polymorphonuclear leukocyte infiltration in the mechanism of anti-inflammatory effect of amiodarone

Ozbakis-Dengiz G. | Halici Z. | Akpinar E. | Cadirci E. | Bilici D. | Gursan N.

Article | 2007 | Pharmacological Reports59 ( 5 ) , pp.538 - 544

In many physiological bodily functions, and in the pathogenesis of inflammation, ions are exchanged between intracellular and extracellular areas. Amiodarone is a multiple ion channel (Ca++, Na+,K+) blocking drug, effective anti-arrhymic drug, and phospholipase inhibitor. The aim of this study is to examine a role of polymorphonuclear leukocyte infiltration in amiodarone's anti-inflammatory effect on experimental paw inflammation. After rats had been assigned to groups, their normal right hind paw volumes were measured using a plethysmometer. Amiodarone (25, 50 and 100, mg/kg) and distilled water were administrated to the experiment . . .al and control groups, respectively, by ip route. Thirty minutes later, paw edema was induced in rats by subplantar injection of 0.1 ml of histamine (0.1%) to those paws. Subsequent volume readings for those paws were carried out at 30-min intervals. Results were expressed as percentages of change from the initial volumes. After the final measurements, the animals were killed by decapitation and their paw tissues were cut for pathological investigation. Amiodarone dose-dependently decreased the paw edema (25.05, 48.71 and 74.97%), and reduced polymorphonuclear leukocyte infiltration in the paw tissue (55.65, 69.76 and 84.58%). Our findings support the view that amiodarone dose-dependently exerts a powerful anti-inflammatory activity. This effect of amiodarone may be due to the activation of nitric oxide resulting from its calcium channel antagonistic effects, to the inhibition of phospholipase A2 and/or to a reduction in neutrophil movement and activation, which may reduce free radical production and proteolytic enzyme release.

Objectives: Inflammation is the most important mechanism of plaque disruption playing an essential role in acute coronary syndromes. It is controversial whether the inflammatory mediators are the cause or the result in the development of plaque rupture. Stimulation of interleukins increases adhesion molecules, fibrinogen and plasminogen activator inhibitors, which cause the activation of inflammation and thrombosis. However, the importance of interleukins in acute coronary syndromes has not been clearly defined. We did not find any article concerning relations between the levels of serum interleukin (IL)-1ß, IL-2, IL -8 and tumor ne . . .crosis factor (TNF)-? in patients with unstable angina pectoris (UAP). So the aim of this study was to determine the levels of serum IL-1ß, IL-2, IL-8 and TNF-? during the early stage of UAP. Methods and results: Thirty-seven patients with UAP (12 females and 25 males; mean age, 57.5 ± 9.7 years) within 6 h of admission and 20 healthy volunteers (eight females and 12 males; mean age, 51.3 ± 6.3 years) were included in the study. IL-1ß, IL-2, IL-8 and TNF-? levels were measured using the enzyme-linked immunosorbent assay method. Patients with acute or chronic inflammation, renal failure or chronic heart failure were excluded from the study. The age, gender and risk factors of the study and control groups were similar. The levels of IL-1ß, IL-8 and TNF-? were significantly increased (p < 0.0001, p < 0.001 and p < 0.016, respectively) in patients with UAP. There was no difference of IL-2 levels between the UAP group and controls. Conclusion: We detected high levels of IL-1ß, IL-8 and TNF-? in patients with UAP during early phase. We suggest that proinflammatory cytokines (e.g. IL-1ß, IL-8, TNF-?) may play an important role in the development of atherosclerosis and its complications Daha fazlası Daha az

Article | 2016 | Sleep and Breathing20 ( 3 ) , pp.939 - 945

Purpose: Inflammation and oxidative stress play important roles in the pathogenesis of obstructive sleep apnoea syndrome (OSAS). Omentin is expressed in visceral adipose tissue and is associated with the inflammatory response. The aim of this study was to assess the relationship between OSAS and omentin based on a comparison of its serum levels at baseline and after 3 months of continuous positive airway pressure (CPAP) therapy. Methods: Ninety-six newly diagnosed OSAS patients and 31 non-apnoeic controls were enrolled in this study. Blood samples were obtained in the morning after polysomnography. Within the OSAS group, 30 patients . . . were started on CPAP therapy and then reassessed clinically, including a blood test for serum omentin and other biochemical analysis, at 3 months. Results: Serum omentin levels were significantly lower in the OSAS group than in the control group (27.7 ± 7.6 and 42.5 ± 5.2 ng/mL, P < 0.001). In the subgroup analysis, omentin concentrations were significantly lower in patients with severe OSAS than in those with mild/moderate OSAS (P < 0.001). Circulating omentin levels were significantly correlated with the apnoea–hypopnoea index (AHI), mean SaO2, oxygen desaturation index, and serum C-reactive protein levels. Treatment with CPAP resulted in a significant increase in circulating omentin levels after 3 months, from 22.7 ± 1.4 to 41.2 ± 3.3 ng/mL (P < 0.001). Conclusions: OSAS is associated with low serum omentin levels, and these levels can be reversed by effective CPAP treatment. © 2016, Springer-Verlag Berlin Heidelberg Daha fazlası Daha az

Aim: The primary percutaneous procedure resulted in a significant improvement in the prognosis of myocardial infarction. However, no-reflow phenomenon restrains this benefit of the process. There are studies suggesting that soluble suppression of tumorigenicity (sST2) can be valuable in the diagnosis and progression of heart failure and myocardial infarction. In this study, we aimed to investigate the effect of sST2 on no-reflow phenomenon in ST-elevated myocardial infarction (STEMI). Method: This study included 379 patients (258 men; mean age, 60±11 years) who underwent primary percutaneous treatment for STEMI. sST2 levels were mea . . .sured from blood samples taken at admission. Patients were divided into two groups according to Thrombolysis in Myocardial Infarction(TIMI) flow grade: group 1 consists of TIMI 0,1,2, accepted as no-reflow, and group 2 consists of TIMI 3, accepted as reflow. Results: No-reflow phenomenon occurred in 60 patients (15.8%). The sST2 level was higher in the no-reflow group (14.2±4.6 vs. 11.3±5.0, p =0.003). Moreover, regression analysis indicated that diabetes mellitus, lower systolic blood pressure, multivessel vascular disease, high plaque burden, and grade 0 initial TIMI flow rate were other independent predictors of the no-reflow phenomenon in our study. Besides, when the patients were divided into high and low sST2 groups according to the cut-off value from the Receiver operating characteristics analysis, being in the high sST2 group was associated with 2.7 times increased odds for no-reflow than being in the low sST2 group. Conclusion: sST2 is one of the independent predictors of the no-reflow phenomenon in STEMI patients undergoing primary percutaneous coronary intervention. © 2019 Japan Atherosclerosis Society Daha fazlası Daha az

Article | 2015 | MEDICAL SCIENCE MONITOR21 , pp.970 - 978

Background: In this study we aimed to explore the effects of pregabalin on a traumatic brain injury model in rats. Material/Methods: This study included 40 adult male Sprague-Dawley rats randomized into 4 groups, each of which contained equal numbers of animals. The control group had no head trauma and thus was not treated. The trauma group had head trauma but was not treated. The pregabalin group had no head trauma but was treated by pregabalin. The trauma + pregabalin group had head trauma treated with pregabalin. The biopsy samples taken from the study animals were histopathologically examined for the presence of edema, inflammat . . .ion, and neuronal damage. Results: All animals in the trauma group had edema, inflammation, and neuronal damage. Four subjects in the control group, 6 in the pregabalin group, and 4 in the trauma + pregabalin group had edema; inflammation was present in 1 subject in the control group, 3 subjects in the pregabalin group, and 3 subjects in the trauma + pregabalin group; neuronal damage existed in 1 subject in the control group, 1 subject in the pregabalin group, and 6 subjects in the trauma + pregabalin group. The trauma group had significantly higher edema and neuronal damage scores than the other groups. Similarly, inflammation was significantly more prevalent in the trauma group than the control and trauma + pregabalin groups. Conclusions: The results of the present study indicated anti-edema, anti-inflammatory, and neuroprotective effects of pregabalin in an experimental head trauma model in rats. Pregabalin may thus be beneficial in humans with acute TBI by relieving concomitant edema and inflammation Daha fazlası Daha az

Article | 2010 | Journal of the Neurological Sciences294 ( 01.Feb ) , pp.38 - 42

Purpose: Multiple Sclerosis (MS) is a disease of the central nervous system characterized by multiple areas of inflammation and demyelination in the white matter of the brain and spinal cord. MEFV gene, which is the main factor in familial Mediterranean fever, is an intracellular regulator of inflammation. This study was designed to determine if known mutations in pyrin domain of MEFV gene are involved in MS and associated with MS morbidity. Methods: Fifty-three patients with MS and 66 healthy subjects, who were all Turkish, were included in this study. Five pyrin gene mutations (E148Q, M680I, M694V, M694I and V726A) were detected i . . .n the patients and controls by using the PRONTO™ FMF Basic Kit according to the manufacturer's instructions. Results: Pyrin gene mutations were found in 20 of the 53 MS patients (38%) and in seven of the 66 healthy subjects (11%). The frequency of total pyrin domain mutations was significantly higher in the MS patients than in the healthy subjects (p < 0.0001). The frequencies of M694V, E148Q and V726A mutations were significantly higher in the patients than in the healthy subjects (p = 0.02, p = 0.013, p = 0.004 respectively). The mean time to reach EDSS score 3.0 was earlier in the patients with MEFV gene mutation (p = 0.02) and the relapse rate was slightly higher among the MS patients carrying MEFV gene mutation (p = 0.04). Conclusion: The results of this study supported the hypothesis that MS patients with MEFV mutation seem to have the susceptibility to develop a more progressive disease. Moreover, these data suggest that MEFV mutations may increase the risk of MS development. © 2010 Elsevier B.V. All rights reserved Daha fazlası Daha az

Article | 2016 | Journal of Neurosurgery: Spine24 ( 6 ) , pp.949 - 959

Objective: Ischemia-reperfusion (I/R) injury of the spinal cord following thoracoabdominal aortic surgery remains the most devastating complication, with a life-changing impact on the patient. Thymoquinone (TQ), the main constituent of the volatile oil from Nigella sativa seeds, is reported to possess strong antioxidant, antiinflammatory, and antiapoptotic properties. This study investigated the effects of TQ administration following I/R injury to the spinal cord. Methods: Thirty-two rats were randomly allocated into 4 groups. Group 1 underwent only laparotomy. For Group 2, aortic clip occlusion was introduced to produce I/R injury. . . . Group 3 was given 30 mg/kg of methylprednisolone intraperitoneally immediately after the I/R injury. Group 4 was given 10 mg/kg of TQ intraperitoneally for 7 days before induction of spinal cord I/R injury, and administration was continued until the animal was euthanized. Locomotor function (Basso, Beattie, and Bresnahan scale and inclined plane test) was assessed at 24 hours postischemia. Spinal cord tissue samples were harvested to analyze tissue concentrations of malondialdehyde, nitric oxide, tumor necrosis factor-?, interleukin-1, superoxide dismutase, glutathione-peroxidase, catalase, and caspase-3. In addition, histological and ultrastructural evaluations were performed. Results: Thymoquinone treatment improved neurological outcome, which was supported by decreased levels of oxidative products (malondialdehyde and nitric oxide) and proinflammatory cytokines (tumor necrosis factor-? and interleukin- 1), increased activities of antioxidant enzymes (superoxide dismutase, glutathione-peroxidase, and catalase), as well as reduction of motor neuron apoptosis. Light microscopy and electron microscopy results also showed preservation of tissue structure in the treatment group. Conclusions: As shown by functional, biochemical, histological, and ultrastructural analysis, TQ exhibits an important protective effect against I/R injury of the spinal cord. © 2016 AANS Daha fazlası Daha az
