ABSTRACT

OBJECTIVE: History, electrocardiogram, age, risk factors, troponin risk score and troponin level follow-up are used to safely discharge low-risk patients with suspected non-ST elevation acute coronary syndrome from the emergency department for a 1-month period. We aimed to comprehensively investigate the 6-month mortality of patients with the history, electrocardiogram, age, risk factors, troponin risk score. METHODS: A total of 949 non-ST elevation acute coronary syndrome patients admitted to the emergency department from 01.01.2019 to 01.10.2019 were included in this retrospective study. History, electrocardiogram, age, risk factors, troponin scores of all patients were calculated by two emergency clinicians and a cardiologist. We compared the 6-month mortality of the groups. RESULTS: The mean age of the patients was 67.9 (56.4-79) years; 57.3% were male and 42.7% were female. Six-month mortality was significantly lower in the high-risk history, electrocardiogram, age, risk factors, troponin score group than in the low- and moderate-risk groups: 11/80 (12.1%), 58/206 (22%), and 150/444 (25.3%), respectively (p=0.019). CONCLUSION: Patients with high history, electrocardiogram, age, risk factors, troponin risk scores are generally treated with coronary angioplasty as soon as possible. We found that the mortality rate of this group of patients was lower in the long term compared with others. Efforts are also needed to reduce the mortality of moderate and low-risk patients. Further studies are needed on the factors affecting the 6-month mortality of moderate and low-risk acute coronary syndrome patients.

ABSTRACT

The purpose of this study was to reveal the combined effects of propolis (P) and quercetin (Q) against diabetic peripheral neuropathy developing with streptozotocin-induced diabetes in rats. Sixty-four adult male rats were divided into eight equal groups: control, P (100 mg/kg/day), Q (100 mg/kg/day), P + Q (100 mg/day for both), diabetes mellitus (DM) (single-dose 60 mg/kg streptozotocin), DM + P, DM + Q, and DM + P + Q. The rats were sacrificed, and blood and sciatic nerve tissues were collected. Blood glucose and malondialdehyde (MDA) levels increased, while IL-6 and total antioxidant status decreased in the DM group (p = 0.016 and p = 0.047, respectively). Ultrastructural findings showed degeneration of the axon and myelin sheath. The apoptotic index (AI %), TNF-α, and IL-1ß immunopositivity increased significantly in the DM group (p < 0.001). Morphological structures approaching those of the controls were observed in the DM + P, DM + Q, and DM + P + Q groups. Morphometric measurements increased markedly in all treatment groups (p < 0.001), while blood glucose and MDA levels, AI (%), TNF-α, and IL-1ß immunopositivity decreased. In conclusion, the combined effects of propolis and quercetin in diabetic neuropathy may provide optimal morphological protection with neuroprotective effects by reducing hyperglycemia, and these may represent a key alternative supplement in regenerative medicine.

ABSTRACT

Colistin, an antibiotic of polymyxin group, has recently been increasingly used in the treatment of multidrug resistant gram-negative bacteria. However, it has serious adverse effects such as acute kidney injury (AKI). We aimed to determine the factors affecting the development of AKI due to colistin, which has serious adverse effects, such as nephrotoxicity and neurotoxicity. We retrospectively analyzed the data of patients who received colistin for multidrug resistant gram-negative sepsis in adult intensive care units between January 2020 and December 2022. Demographic data, blood test results, concomitant drug use, need for renal replacement therapy, and mortality were recorded. Kidney damage was assessed according to the Kidney Disease Improving Global Outcomes criterion. We obtained data from 103 patients, 45 (43.7%) of whom were women. The most common comorbidity was a neurological disorder. Renal damage developed in 59.2% of patients. Renal replacement was required in 50.8% of the patients. Among patients who received colistin, 64.1% died. The use of vasopressors, diuretics, nephrotoxic agents with colistin, advanced age, and hypoalbuminemia were more common in patients with renal injury. Multivariate regression analysis showed that vasopressor use, prior creatinine elevation, and diuretic use were independent risk factors for colistin-induced AKI. Vasoactive agent use, previous kidney injury, and furosemide use were independent risk factors for colistin-induced nephrotoxicity. Considering these factors may be instructive for better monitoring of patients when colistin is required in intensive care units.

ABSTRACT

OBJECTIVE: A 1-day point prevalence study was planned to obtain country data by determining the clinical characteristics, follow-up and treatment methods of coronavirus disease 2019 (COVID-19) cases that required intensive care unit (ICU) treatment in the second year of the pandemic. MATERIAL AND METHODS: All patients who were hospitalized in the ICUs due to COVID-19 between March 11, 2022, 08.00 am, and March 12, 2022, 08.00 am, were included in the study. Demographic characteristics, intensive care and laboratory data, radiological characteristics, and follow-up results of the patients were recorded. RESULTS: A total of 811 patients from 59 centers were included in the study, 59% of the cases were male, and the mean age was 74 ± 14 years. At least one comorbid disease was present in 94% of the cases, and hypertension was the most common. When ICU weight scores were examined, Acute Physiology and Chronic Health Evaluation-II: 19 (15-27) and Sequential Organ Failure Assessment: 7 (4-10) were seen. Sepsis was present in 37% (n = 298) of cases. PaO2/FiO2 ratios of the patients were 190 the highest and 150 the lowest and 51% of the cases were followed via invasive mechanical ventilation. On the study day, 73% bilateral involvement was seen on chest x-ray, and ground-glass opacities (52%) were the most common on chest tomography. There was growth in culture in 40% (n = 318) of the cases, and the most common growth was in the tracheal aspirate (42%). CONCLUSION: The clinical course of COVID-19 is variable, and ICU follow-up was required due to advanced age, comorbidity, presence of respiratory symptoms, and widespread radiological involvement. The need for respiratory support and the presence of secondary infection are important issues to be considered in the follow-up. Despite the end of the second year of the pandemic and vaccination, the high severity of the disease as well as the need for follow-up in ICUs has shown that COVID-19 is an important health problem.

ABSTRACT

Women undergoing breast surgery seem to be under the risk for hypothermia (central body temperature <36°) due to the uncertainty caused by the preoperative preparation time and the variety of operations, leading to neglect of warming precautions. The study examines the perioperative hypothermia (PH) in breast surgery and the relationships between the depth of decrease in body temperature and individual or clinical variables. This prospective, cross-sectional, observational study includes 120 female patients 18-65 years of age who were given general anesthesia for breast surgery. The incidence of hypothermia was 68.1%. The given patients were discriminated as body temperature <36°, hypothermia was significantly related with lower weight, body mass index, American Society of Anesthesiology (ASA) score, baseline body temperatures, higher extubation, and recovery times. When patients' temperature decreases by >1 or 1.5°, lower age and longer durations of operation and anesthesia were also significant variables. The incidence of shivering is quite high at temperatures below 36°C or at 1 and 1.5°C reductions from baseline (72.7%, 84%, 94.1%, respectively). Body temperature changes of the patients had no effect on nausea-vomiting and pain scores. It turned out that the incidence of PH and shivering is high in women who underwent breast surgery. We think that the depth of decrease in body temperature should be taken into account when evaluating the predictors or clinical consequences of hypothermia, except for the 36°C limit for body temperature.

ABSTRACT

Eosinophilic cellulitis (EC) is a skin disease characterized by pruritic, non-purulent, erythematous plaques and histologically by edema and eosinophil infiltration in the dermis. The etiopathogenesis of the disease is not fully elucidated. It differs from infectious cellulitis by being unresponsive to antibiotics and recurring. This case report presents a late-diagnosed case of EC in a patient who did not respond to long-term and broad-spectrum antibiotics. This case underscores the importance of skin biopsy and histopathological diagnosis in patients with recurrent, non-responsive, antibiotic-resistant, and cellulitis-like clinical features resembling infectious cellulitis; "eosinophilic cellulitis" should be considered in the differential diagnosis.

ABSTRACT

OBJECTIVE: Due to being the weakest sutural junction of the crania and relations with intracranial anatomical structures, the accurate location of the pterion is important for surgical approaches such as in pterional craniotomy. The aim of the study was to develop regression equations to estimate the person-specific accurate location of the pterion based on the cranial morphometry. MATERIALS AND METHODS: The study was conducted on 22 pterions located 11 dry skulls belonging to Anatomy Department of the Harran University, Medical Faculty. Twelve parameters related to pterion and 23 parameters related to the skull was measured using ImageJ software. SPSS 20.0 was performed for statistical analyses such as descriptive and comparative statistics and developing regression equations. RESULTS: Statistically significant difference wasn't observed between right and left sides. The 12 equations, such as P8:distance between pterion and the tip of the mastoid process= 63,780 + (1,366 × K6) - (2,786 × K7) + (1,342 × K11) - (1,029 × K13) + (2,102 × K14) - (1,710 × K15) - (0,517 × 22) Adjusted R2= 0.995 and Standard Errors = 1.221 were developed to estimate the accurate location of the pterion based on the cranial morphometry. CONCLUSIONS: In the previous studies, the mean distances of the pterion to certain landmarks on the crania were given. The authors developed formulas in order to estimate the accurate person-specific location of the pterion. The authors are convinced that the equations they have developed will help neurosurgeons in terms of surgical approaches.

ABSTRACT

The tetanus vaccine is not routinely given to Turkish adults. Protective tetanus immunity decreases with age. Health-care personnel (HCPs), who are role models in the field of health, are a target group in order to achieve a higher rate of tetanus vaccination in the community. This study was designed to evaluate attitudes and coverage regarding tetanus vaccination among a large sample of Turkish HCPs. This cross-sectional epidemiologic study was conducted from July to August 2019. A questionnaire was sent to HCPs using social media. Of the 10,644 HCPs included in the study, 65% were female. Overall, the tetanus vaccination coverage (TVC) among HCPs was 78.5% (95% CI: 77.7%-79.3%). TVC was significantly higher among physicians [83.4% (95% CI: 82%-84.6%); p < .001] compared with all other HCPs except nurses. Older age (≥40 years) and length of professional experience were significantly correlated with TVC. Of the 8353 HCPs who received tetanus vaccines during their lifetime, 73.03% received tetanus vaccination in the past 10 years. The self-vaccination rate for protection against tetanus was 13.1%. Acute injuries (25.42%) and pregnancy (23.9%) were the most common reasons for having the tetanus vaccine. One-third (33.7%) of HCPs did not have information about whether pregnant women could receive tetanus vaccinations. This survey study provided excellent baseline information about HCPs' coverage rates and attitudes regarding tetanus vaccination. The present results suggested that tetanus boosters for HCPs should be established as soon as possible, and revealed that the HCPs younger than 30 years with relatively less professional experience and all other HCPs except nurses and physicians should be identified as the target population for future intervention programs.

ABSTRACT

AIM: Influenza vaccination is the most effective method in prevention of influenza disease and its complications. Our study aimed to investigate the rates of vaccination and the behaviours and attitudes against the vaccine in healthcare workers in Turkey. METHODS: This multicentre national survey is a descriptive study in which 12 475 healthcare workers. Healthcare workers were asked to answer the questionnaire consisting of 12 questions via the survey. RESULTS: It was found that 6.7% of the healthcare workers regularly got vaccinated each year and that 55% had never had the influenza vaccine before. The biggest obstacle against getting vaccinated was determined as not believing in the necessity of the vaccine (53.1%). CONCLUSION: The rates of influenza vaccination in healthcare workers in Turkey are quite low. False knowledge and attitudes on the vaccine and disease are seen as the most important reasons to decline vaccination. It is important to detect reasons for anti-vaccination and set a course in order to increase the rates of vaccination.

ABSTRACT

PURPOSE: The nasal and labial characteristics along with the other facial characteristics are different between races. The purpose of this study is to identify nasal and labial features of Turkish women by anthropometric measurements and indices besides to detect variances with aging. METHODS: The study was conducted with total 302 women volunteers whose ages were between 19 and 85. The women included were divided into 3 groups according to their ages; respectively young (ages between 19 and 44), middle-aged (45-59) and senior (>60). By using camera footages with the IT version 3.00 software program, anthropometric measurements of the nasolabial region was performed. RESULTS: The mean nasal length of the included participants was measured as 38.56 ±â€Š8.32 mm while mean nasal height was 50.05 ±â€Š8.36 mm. Mean nasal root width was 13.24 ±â€Š2.70 mm, mean morphological nasal width was 32.16 ±â€Š5.80 mm and mean anatomical nasal width was 27.85 ±â€Š4.92 mm. In addition, mean nasal depth was 19.55 ±â€Š5.25 mm.In the middle-aged group of participants, the nasal length was more than senior group (P < 0.05). Nasal root width was increased with aging (P < 0.05). Morphological and anatomical widths of the nose were increased with aging but increase rate was lower in the senior group (P < 0.05). The nasal depth was lower in the young group in comparison with middle-aged and senior groups (P < 0.05). When nostril types were analyzed; ratios of 'teardrop', 'heart-shaped', 'annular' and 'triangular' types were 51.65%, 0.99%, 6.95%, and 40.39%, respectively. CONCLUSIONS: To be acquainted with facial anthropometric features and measurements of nasolabial region which varies with races and aging; would have a significant importance in view of conserving the facial ratio and esthetics in the plastic and reconstructive surgery field.

ABSTRACT

PURPOSE: This study aims to determine the number, symmetry, shape and individual characteristic of palatal rugae. METHODS: In our study, we performed on subjects ages 16 to 57 (23.01 ±â€Š7.12), ranging from a total of 230 (108 female and 122 male). Alginant impression material from each took dimensions of the upper jaw. Then casts were obtained by pouring hard casts. The shapes, lengths, and directions of rugae measured on these casts. The palatine photos were taken by using a mobile phone-Samsung brand with 12 MP camera and an orthodontic mirror. The casts and photographs were selected at random belonging to 100 subjects. Selected at random 10 photographs were matched among 100 casts. The ratios of correct matches were determined. RESULTS: In our study, the total number of palatal rugae was found as 9.49 ±â€Š1.87 in females and 9.42 ±â€Š1.92 in males. The most detected rugae pattern was wavy on both females and males. The most rarely seen rugae pattern was converged in the males and circular in the females. Regarding lengths of rugae, the most detected rugae pattern was the primary one. Regarding the direction of rugae pattern, positive-sided one was the most dominant in both genders. We determined the ratio of matching the casts belonging to Palatine with the photos as 63.5%. The number of rugae aged under 18 and above 41 was found to be statistically significant (P = 0.003), but the number of curved and positive-sided rugae in older ages was not found to be statistically significant. CONCLUSIONS: Compared with data from earlier studies, the shapes, length, and direction of palatal rugae were seen specific in every individual, and it was seen to have discriminating characteristics among different populations. The possible differences in individual specific palatal rugae require further studies involving larger samples.

ABSTRACT

INTRODUCTION: Cystic echinococcosis is an endemic disease in east Turkey. Echinococcosis granulosus is reported as the most common agent of cystic echinoccocus. Hydatid cysts are generally involved in lung and liver. PRESENTATION OF CASE: 37 year old female admitted to our clinic with cough and expectoration of watery material progressing within 3 months. Thorax CT demonstrated a 110*100 mm well defined cavitary lesion in the right lower lobe of the lung. The patient was treated with cystotomy & capitonnage and postoperative albendazole treatment successfully. DISCUSSION: Hydatid cysts should be conceived in differential diagnosis of pulmonary cystic lesions. CONCLUSIONS: The basic treatment for cystic echinococcosis is surgery. Postoperative antihelminthic therapy is preferred to prevent postoperative complications.

ABSTRACT

PURPOSE: Normal morphometric values of the orbital region vary according to age, sex, and ethnicity. The purpose of this study was to determine the normal values of orbital region and analysis age-related changes in adult women. METHODS: Measurements were performed on 311 healthy women, aged between 20 and 87. Subjects were divided into 3 age groups: young (20-44), middle aged (45-59), and old adults (60 and up). The anthropometric measurements of orbital region were performed on the photographs by using IT version 3.00 software programs. RESULTS: The mean values of interpupillar distance and nasofrontal angle were 64.20 ±â€Š5.06 mm, 149.21 ±â€Š9.12° respectively. In young, middle, and old groups the values of outer canthal distance were 92.98 ±â€Š5.85, 91.00 ±â€Š7.04, and 88.02 ±â€Š6.13 mm; inner canthal distances were 31.30 ±â€Š3.07, 31.72 ±â€Š3.51, and 31.66 ±â€Š3.44 mm. Palpebral fissure areas were 163.41 ±â€Š29.98, 144.01 ±â€Š30.90, and 129.11 ±â€Š27.21 mm. Palpebral fissure lengths were 29.96 ±â€Š1.76, 28.45 ±â€Š1.96, and 26.81 ±â€Š1.95 mm; palpebral fissure widths were 9.27 ±â€Š1.21, 8.57 ±â€Š1.25, and 7.98 ±â€Š1.18 mm. Inner canthal angles were 39.29 ±â€Š6.04°, 37.57 ±â€Š6.58°, and 35.78 ±â€Š5.80°; outer canthal angles were 53.90 ±â€Š8.90°, 51.48 ±â€Š8.87°, and 49.87 ±â€Š9.78°. Visible iris areas were 96.04 ±â€Š15.04, 88.63 ±â€Š16.27, and 81.73 ±â€Š14.03 mm, respectively. Interpupillary distance and inner chantal distance measurements showed no significant difference with age. As other measurements were determined decreased with age (P <0.05). CONCLUSIONS: The authors believe that knowing the normal size of the structures in the orbital region and age-related changes will be useful to maintain the facial proportions in the plastic and reconstructive surgery and to protect aesthetic appearance of the face.

ABSTRACT

BACKGROUND: Familial Mediterranean Fever (FMF) is an autosomal recessive form of recurrent episodes of fever and an autoinflammatory disease characterized by inflammation of the serous membranes. The clinical diagnosis is supported by the laboratory findings. This study investigated the relationship of Serum Amyloid A (SAA), YKL-40, and Pentraxin-3 (PTX-3) with the FMF disease. METHODS: About 50 patients with FMF were enrolled in this study. Patients were divided into three groups according to disease severity score (mild, moderate, and severe). Thirty-seven healthy individuals were included as the control group. Serum SAA, YKL-40, and PTX-3 concentrations were measured using an ELISA kit. RESULTS: Serum SAA and YKL-40 levels of FMF patients were significantly higher than in the control (P < 0.001). PTX-3 levels were found to be higher in patients even though there was no significant difference (P = 0.113). Whereas the positive predictive value was 71.9% for cut-off point of SAA, the positive predictive value was 83.3% for cut-off point of YKL-40. Whereas a significant correlation was detected in SAA and PTX-3 with YKL-40 (respectively; P = 0.036, P < 0.001), there was no correlation between the PTX-3 with SAA (P = 0.219). CONCLUSIONS: YKL-40 can be used together with SAA to support the diagnosis of FMF and to monitor the severity of the disease. In this study, YKL-40 levels were examined for the first time in FMF patients and further studies are necessary using larger patient samples.

ABSTRACT

INTRODUCTION: Apelin is an adipokine secreted by the adipose tissue and by the endothelial cells in various parts of the body. Apelin is also expressed by the glomerular arteriolar rectus and glomerular capillary cells. We evaluated the relationship between the initial serum levels of apelin 13 with the trend of glomerular filtration rate (GFR) during a 1-year follow-up of patients with chronic kidney disease (CKD). MATERIALS AND METHODS: Ninety-nine patients with CKD in the predialysis stages were included and completed the study. The demographic data, medications, and comorbidities of the patients were recorded. The relationship between the baseline apelin 13 levels and the 1-year GFR loss was evaluated.   Results. The mean 1-year GFR loss 1.6 mL/min for those with CKD stage 3, 5.1 mL/min for those with CKD stage 4, and 2.6 mL/min for those with CKD stage 5. Fifty-eight patients (58.6%) had a GFR loss less than 5 mL/min and 41 (41.4%) had a GFR loss of 5 mL/min and greater, for whom the mean apelin 13 levels were 2169 ± 1807 mL/min and 2513 ± 1920 mL/min, respectively (P = .36).  There was no significant correlation between the apelin 13 levels and GFR loss (P = .35). CONCLUSIONS: To our knowledge, this study was the first that clinically examined the relationship between apelin 13 and CKD progression. Apart from the diabetic nephropathy, several factors causing comorbidity and progression may have probably masked this potential relationship.

ABSTRACT

BACKGROUND/AIM: To investigate the neuroprotective effects of glucagon-like peptide 2 (Glp-2), which increases cerebral blood flow, on the hippocampal complex after cerebral ischemia/reperfusion (I/R) injury in rats. MATERIALS AND METHODS: Animals were randomized into 4 groups: sham, I/R + 0.9% NaCl, I/R + pre-Glp-2, and I/R + post-Glp-2. Cerebral ischemia was performed via the occlusion of the bilateral internal carotid artery for 40 min and continued with a reperfusion process. At the end of 6 h of reperfusion, animals were decapitated in all groups and brain tissues were removed. Malondialdehyde (MDA) and natural intracellular antioxidant glutathione (GSH) levels and myeloperoxidase (MPO) activities were measured in the left hippocampal tissue. The right hippocampal tissues of all group members were taken for histopathologic study. RESULTS: MDA levels and MPO activities increased from Group I to Group II and decreased from Group II to Groups III and IV. On the other hand, GSH levels were not significantly different among the groups. The number of apoptotic hippocampal tissue cells increased from Group I to Group II and decreased from Group II to Groups III and IV. CONCLUSION: Our preliminary study revealed that Glp-2 treatment may decrease oxidative damage from I/R in cerebral tissue.

ABSTRACT

Glucagon-like peptide-2 (GLP-2) has potent anti-inflammatory effects and protects against experimental ischemia/reperfusion (I/R) injury in pulmonary, intestinal, and myocardial tissue. However, its protective abilities against I/R injury in the liver are unknown. We investigated the potential role of GLP-2 pretreatment on hepatic I/R injury in rats. A total of 24 rats were randomly divided into three groups (n = 8). The first group was the control group; the second group was the vehicle-treated hepatic ischemia/reperfusion (HIR, vehicle saline-treated) group; and the third group was the GLP-2 pretreated I/R (GLP2-IR) group. Each rat in the third group was intraperitoneally administered 5 µg GLP-2 for 5 d before the procedure. A portal triad was created to induce ischemia with a vascular atraumatic clamp. After 40 min, the clamp was released to initiate hepatic reperfusion for 6 h. Blood samples and tissue specimens from the liver were obtained. Alanine aminotransferase, aspartate aminotransferase, and total bilirubin levels significantly increased in the salinetreated HIR group (P < 0.001), whereas GLP-2 pretreatment significantly decreased their levels (P < 0.01). Our data suggested that GLP-2 pretreatment may have a protective effect on liver I/R injury. However, dose-response studies are necessary to determine the most effective dose.

ABSTRACT

OBJECTIVES: Stroke poses a crucial risk for mortality and morbidity. Our study aimed to investigate the effect of p-coumaric acid on focal cerebral ischemia in rats. MATERIAL AND METHODS: Rats were randomly divided into four groups, namely Group I (control rats), Group II (ischemia rats), Group III (6 hr ischemia + p-coumaric acid rats) and Group IV (24 hr ischemia + p-coumaric acid rats). Cerebral ischemia was induced via intraluminal monofilament occlusion model. In all groups, the brain was removed after the procedure and rats were sacrificed. Malondialdehyde, superoxide dismutase and nuclear respiratory factor-1 were measured in the ischemic hemisphere. The histopathological changes were observed in the right hemisphere within the samples. Functional assessment was performed for neurological deficit scores. RESULTS: Following the treatment, biochemical factors changed significantly. Histopathologically, it was shown that p-coumaric acid decreased the oxidative damage. The neurological deficit scores of p-coumaric acid-treated rats were significantly improved after cerebral ischemia. CONCLUSION: Our results showed that p-coumaric acid is a neuroprotective agent on account of its strong anti-oxidant and anti-apoptotic features. Moreover, p-coumaric acid decreased the focal ischemia. Extra effort should be made to introduce p-coumaric acid as a promising therapeutic agent to be utilized for treatment of human cerebral ischemia in the future.

ABSTRACT

PURPOSE: To investigate the neuroprotective effects of Sulindac on the hippocampal complex after global cerebral ischemia/reperfusion (I/R) injury in rats. METHODS: Thirty one Sprague-Dawley rats were used, distributed into group I (sham) n:7 were used as control. For group II (n:8), III (n:8) and IV (n:8) rats, cerebral ischemia was performed via the occlusion of bilateral internal carotid artery for 45 minutes and continued with reperfusion process. 0.3 mL/kg/h 0.9 % sodium chloride was infused intraperitoneally to the Group II rats before ischemia, 5µg/kg/h/0.3 ml sulindac was infused intraperitoneally to the Group III rats before ischemia and 5µg/kg/h/0.3 ml sulindac was infused intraperitoneally to the Group IV rats after ischemia and before reperfusion process. The levels of MDA, GSH and MPO activity were measured in the left hippocampus tissue. The hippocampal tissue of all group members were taken for histopathological study. RESULTS: The MDA and MPO levels increased from group I (control) to group II (I/R) (P<0.05) and decreased from group II (I/R) to group III (presulindac + I/R) and IV (postsulindac + I/R) (P<0.05). Beside these, the GSH levels decreased from group I (control) to group II (I/R) (P<0.05) and increased from group II (I/R) to group III (presulindac + I/R) and IV (postsulindac + I/R) (P<0.05).The number of apoptotic neurons increased from group I (control) to group II (I/R) (P<0.05) and decreased from group II (I/R) to group III (presulindac + I/R) and IV (postsulindac + I/R) (P<0.05). CONCLUSION: The Sulindac may have neuroprotective effects on ischemic neural tissue to prevent the reperfusion injury after ischemia.
