Öğe Alkol Tüketimi, Ilaç Kullanimi ve Bazi Hastaliklarda Eritrosit Katalaz Aktiviteleri(İnönü Üniversitesi Tıp Fakültesi Dergisi, 2002) Temel, Ismail; Özerol, Elif; Bay, Aysun; Çigli, Ahmet; Akyol, ÖmerKatalaz (CAT) hidrojen peroksidin parçalanmasinda katalitik rol oynarken, peroksidin hidrojen donörüne okside edilmesinde peroksidik bir rol oynar. Bu çalismada alkol tüketimi, ilaçlar ve hastaliklarin eritrosit katalaz aktivitesi üzerine etkisini arastirmak amaçlanmistir. Bu amaç için denekler 3 farkli gruba ayrildilar; 1- alkol alan ve almayan 2- ilaç alan ve almayan 3- lösemi, hepatit, diabetes mellitus ve kardiyak hastaliklari olanlar. Katalaz aktivitesi Aebi metodu ile ölçüldü. Hemoglobin düzeyleri Olympus AU-600 otoanalizörüyle tayin edildi. MCH, HCT, MCHC, MCV ve RBC gibi hematolojik degerler Coulter STKS cihaziyla çalisildi. Ilaç alan ve almayanlarin katalaz aktivitesinde bir farklilik gözlenmedi (3155 ? 1039 k/g Hb ve 3051 ? 956 k/g Hb, p>.0,05). Saglikli kisilerdeki ile lösemililerin, kalp hastalarinin, hepatitlilerin ve diabetes mellituslularin katalaz aktiviteleri arasinda fark bulunamadi. Alkol ile enzim aktivitesi belirgin bir sekilde artti. CAT aktiviteleri alkol almayanlarda 3059 ? 958 k/g Hb ve alkol alanlarda 3644 ? 984 k/g Hb olarak bulundu (p<0,03).Öğe An antibody of TNF-alpha did not prevent thioacetamide-induced hepatotoxicity in rats(Sage Publications Ltd, 2011) Demirel, Ulvi; Harputluoglu, Murat M. M.; Seckin, Yuksel; Ciralik, Harun; Temel, Ismail; Ozyalin, Fatma; Otlu, BarisTumor necrosis factor (TNF)-alpha antibodies have been shown to reduce liver damage in different models. We investigated the effects of infliximab (a TNF-alpha antibody) on liver damage in thioacetamide (TAA)-induced hepatotoxicity in rats. Group 1 (n = 8) was the control group. In group 2 (n = 8), the TAA group, the rats received 300 mg/kg intraperitoneal (ip) TAA daily for 2 days. In group 3 (n = 8), the TAA + Infliximab (INF) group, infliximab (5 mg/kg ip daily) was administered 48 hours before the first dose of TAA daily for 2 days and was maintained for 4 consecutive days. In group 4 (n = 8), the INF group, the rats received only ip infliximab (5 mg/kg) daily. Livers were excised for histopathological and biochemical tests (thiobarbituric-acid-reactive substances [TBARS], and myeloperoxidase [MPO]). Serum ammonia, aspartate transaminase (AST), alanine transaminase (ALT), TNF-alpha, liver TBARS and MPO levels, and liver necrosis and inflammation scores in the TAA group were significantly higher than in the control and INF groups (all p < 0.01). All parameters except AST were not significantly different between TAA and TAA + INF. In conclusion, our results suggest that oxidative stress plays an important role in TAA-induced hepatotoxicity, and infliximab does not improve oxidative liver damage.Öğe Celiac disease in children with urolithiasis(Turkish J Pediatrics, 2012) Menekse, Engin; Selimoglu, Mukadder Ayse; Temel, Ismail; Tabel, Yilmaz; Gurgoze, MetinThere are a few studies suggesting a relationship between celiac disease (CD) and kidney disease, but no study has investigated CD in patients with urolithiasis. In this study, we aimed to determine the prevalence of CD in infants and children with urolithiasis. One hundred and eighty-seven infants and children (4 months-17 years) with urolithiasis, and 278 age- and sex-matched healthy children were included. CD was screened using tissue transglutaminase (tTG) immunoglobulin (Ig) A. Seropositive cases, whose parents gave consent, underwent upper gastrointestinal system endoscopy for duodenal biopsy. Seven (3.7%) among those with urolithiasis and one (0.3%) among controls were positive for tTG IgA (p=0.008). Six of the urolithiasis group and one from the control group underwent upper gastrointestinal endoscopy. Intestinal biopsy revealed Marsh-Oberhuber type 1 intestinal lesions in two children. The other five had normal histology. Biopsy-proven CD was detected in two (1%) children with urolithiasis. The prevalence of biopsy-proven CD among all cases was 0.4%. When children were evaluated with respect to age factor, it was found that seropositivity in children younger and older than two years was not different (4% vs. 3.6%; p=0.880). In this first study investigating CD prevalence in children with urolithiasis, we found a higher seropositivity for CD in children with urolithiasis compared to controls, but in terms of biopsy-proven CD, no difference was found.Öğe The effects of apricot on serum proteins and liver enzymes in rats(Vup Food Research Inst, Bratislava, 2013) Yilmaz, Ismet; Temel, Ismail; Gursoy, Sule; Dogan, ZumrutThis study aimed to investigate the effects of different rates and feeding periods of sun-dried organic apricot (SDOA) supplementation on serum proteins and liver enzymes in rats. Numbers of 120 male and 120 female rats were randomly divided into five groups. The control group was fed with normal rat chow, and the others with 1%, 2.5%, 5% and 10% SDOA-supplemented diet, respectively. At the end of the 30th day of feeding periods, blood samples of 8 rats from each gender of every group were taken. Serum samples were used for measurements of albumin (ALB), total protein (TP), alanine aminotransferase (ALT), aspartate aminotransferase (AST) and alkaline phosphatase (ALP) levels. This procedure was repeated on the 60th and 120th days. Effects of rates and periods on parameters and interactions were investigated by two-way ANOVA. As the rates of SDOA in diet increased, decreases were observed in all parameters of males, and in ALP, AST and TP parameters of females. Considering periods, an effective role was observed on ALB, ALT and TP levels in genders. However, there were no significant interactions between rates and periods. The rate of 1% had beneficial effect on parameters in genders. However, the optimal period was not determined.Öğe Effects of Rifaximin on Bacterial Translocation in Thioacetamide-Induced Liver Injury in Rats(Springer/Plenum Publishers, 2012) Harputluoglu, Murat M. M.; Demirel, Ulvi; Gul, Mehmet; Temel, Ismail; Gursoy, Sule; Selcuk, Engin Burak; Aladag, MuratIntestinal bacterial overgrowth (IBO) and increased mucosal permeability are suggested to increase bacterial translocation (BT) in liver injury. Rifaximin (RIF) is a minimally absorbed oral antimicrobial agent that restores gut microflora imbalance. The aim of the present study was to investigate the effects of RIF on BT frequency in thioacetamide (TAA)-induced liver injury. Group 1 was the control. In group 2 (TAA), rats received TAA daily for 3 days. In group 3 (TAA + RIF), RIF was commenced on the same day as the first dose of TAA. In group 4 (RIF), rats received only RIF. Ileal aspirate Escherichia coli counts were significantly lower in the TAA + RIF group than in TAA group. There was no difference in BT frequency between the TAA and TAA + RIF groups. Our results suggest that factors such as intestinal barrier dysfunction and impaired host immune shield, apart from IBO, play an important role in BT in this model.Öğe Effects of sun dried organic apricot on serum total cholesterol, high density lipoprotein-cholesterol, triglyceride and total antioxidant capacity levels in rats(2020) Yilmaz, Ismet; Temel, Ismail; Aydemir, SongulAim: In this study, we aimed to investigate the effects of sun dried organic apricot (SDOA) consumption on serum Total Cholesterol (TC), High-Density Lipoprotein-Cholesterol (HDL-C), Triglyceride (TG) and Total Antioxidant Capacity (TAC) levels in ratsMaterial and Methods: 120 males, 120 females rats were divided in to four groups according to their SDOA rates (1%, 2.5, 5 and 10) in chow (to be 24 rats in each gruop), and feding periods. At 120 days periods, the control group was fed with standard rat chow and the others were fed with 1%, 2.5, 5 and 10 SDOA supplemented diet. At the end of 30th, 60th, 120th days; 8 rats which each genders/ groups were sacrified by diethyl ether inhalation anesthesia, app. 8-10 mL blood samples were taken by intracardiac puncture and obtained serum samples were maintained at -20 ° C until the day of analysis.Results: After statistical analysis, TC levels of male rats; HDL-C levels of female rats increased in paralel with the feding process. Both TC and HDL-C levels of female rats were significantly higher than those of males. Although there were a significant decreases in TG levels of both sexes at the end of feding periods, there was no significant difference between TG levels of both genders.Conclusion: It is thought that increases in TC and HDL-C levels are caused by rats affected by long-term feding periods. In addition, the significant difference between TC and HDL-C levels of male and female rats are thought to be affected by gender-specific reference values. The decrease in TG levels in both sexes is considered to be due to the increased energy needs of rats as well as the effect of SDOA-added feeds.Öğe Elimination of NTproBNP in peritoneal dialysis patients Does peritoneal membrane type make a difference in plasma level and elimination of NTproBNP?(Dustri-Verlag Dr Karl Feistle, 2016) Koz, Suleyman; Sahin, Idris; Temel, Ismail; Koz, Sema T.; Terzi, ZaferBackground: Brain natriuretic peptide and its derivative peptide NTproBNP are utilized to exclude cardiac diseases, and predicting risk of mortality in dialysis patients. Our aim was to evaluate both elimination of NTproBNP through dialysate and a possible relationship between plasma and/or dialysate NTproBNP level and membrane transport status of peritoneal dialysis patients. Methods: 57 plasma (P) and dialysate (D) samples of 44 peritoneal dialysis (PD) patients were analyzed for NTproBNP. Modified peritoneal equilibration test (PET) results and other variables were obtained from the charts. Results: Median (IQR) NTproBNP concentrations (pg/mL x 1,000) in P and D were 3.3 (1 - 13) and 0.5 (0.2 - 3.6), respectively. There was a linear correlation between P-NTproBNP and D-NTproBNP (r = 0.928, p = 0.0001; regression equation was y = 0.897(*)x -0.28). Mean P/D-NTproBNP ratio was 5.5 +/- 0.5. Median P and D-NTproBNP levels by the membrane transport status were aligned as high (H) > high average (HA) > low average (LA), and the difference between H and LA was statistically significant (p < 0.001). Mean arterial pressure (MAP), residual Kt/V and dialysate/plasma ratio of crearinine (D/P Cr) were significant predictors of D-NTproBNP; whereas only MAP and residual Kt/V were significant predictors of P-NTproBNP in multiple regression analysis. Both P-and D-NTproBNP have significant and similar size of correlations with MAP, albumin, D/P Cr ratio, and Na. Conclusions: D-NTproBNP level is similar to 1/5 of P-NTproBNP, and the issue of relationship between membrane transport status and natriuretic peptide levels needs more work.Öğe Methylprednisolone prevents bacterial translocation in thioacetamide-induced liver failure in rats(Aves, 2017) Harputluoglu, Murat Muhsin Muhip; Temel, Ismail; Demirel, Ulvi; Seckin, Yuksel; Aladag, Murat; Otlu, Baris; Karadag, NeseBackground/Aims: Steroids have been shown to prevent intestinal oxidative stress. We investigated the effects of methylprednisolone on intestinal oxidative damage and bacterial translocation in thioacetamide-induced liver failure in rats. Materials and Methods: Group 1 (n=8) was the control group. In group 2 (n=8), the thioacetamide group, rats received 300 mg/kg intraperitoneal thioacetamide daily for 2 days. In group 3 (n=8), the thioacetami de+methylprednisolone group, treatment with methylprednisolone (30 mg/kg intraperitoneal) was commenced 48 h before the first dose of thioacetamide. In group 4 (n=8), the methylprednisolone group, the rats received only methylprednisolone (30 mg/kg intraperitoneal). Results: Serious hepatic and intestinal oxidative damage and high bacterial translocation frequencies were observed in the thioacetamide group compared with those of the controls. Bacterial translocation frequency in the thioacetamide+methylprednisolone group was significantly lower than that in the thioacetamide group (p<0.05). Intestinal thiobarbituric acid-reactive substances and myeloperoxidase levels and tissue damage scores for the intestines in the thioacetamide+methylprednisolone group were lower than those in the thioacetamide group (p<0.01, p<0.01, and p<0.0001, respectively). Conclusion: Our findings suggest that methylprednisolone reduces bacterial translocation by preventing intestinal oxidative damage in this model of acute liver failure in rats.Öğe Prevalence of celiac disease in parents of preterm or low birthweight newborns(Wiley, 2011) Ozgor, Bilge; Selimoglu, Mukadder Ayse; Temel, Ismail; Seckin, Yuksel; Kafkasli, AyseAim: Celiac disease (CD) may present with atypical symptoms, including poor pregnancy outcomes, such as preterm and low birthweight (LBW) deliveries, thus we aimed to investigate the frequency of CD in mothers and fathers of preterm or LBW newborns. Materials and Methods: In this study, 316 parents of 164 preterm or LBW newborns and 246 parents of 123 healthy newborns were included. CD was screened using tissue transglutaminase immunoglobulin A. Endoscopic duodenal biopsy was provided in the seropositive cases. Results: Positive tissue transglutaminase immunoglobulin A was found in six (1.1%; 1/94) individuals (three mothers and three fathers); five were from the study group (1.6%; 1/63) and one was from the control group (0.4%; 1/246). CD prevalence in mothers, fathers and parents of preterm newborns was 1/57 (1.8%), 1/57 (1.8%) and 1/29 (3.5%), respectively. In the LBW group, seropositivity in fathers was 1/50 (2%) with no seropositive mothers. Biopsy-proven CD was found in 1/159 mothers (0.6%) and 1/79 fathers (1.3%). Mean birthweights of the newborns of seropositive mothers and fathers were 214 g (P < 0.05) and 320 g lower than those of seronegative ones, respectively. However, in logistic regression analysis it was found that seropositivity of mothers or fathers did not affect gestational age or birthweight of the newborns. Conclusion: Because the prevalence of CD in parents of preterm or LBW newborns is not statistically higher than the healthy population, routine CD screening in that group cannot be recommended at the time being. For more definite conclusions further studies are needed.Öğe The prevalence of nutritional anemia in pregnancy in an east Anatolian province, Turkey(Bmc, 2010) Karaoglu, Leyla; Pehlivan, Erkan; Egri, Mucahit; Deprem, Cihan; Gunes, Gulsen; Genc, Metin F.; Temel, IsmailBackground: Anemia is considered a severe public health problem by World Health Organization when anemia prevalence is equal to or greater than 40% in the population. The purpose of this study was to determine the anemia prevalence with the associated factors in pregnant women and to determine the serum iron, folate and B12 vitamin status in anaemic pregnants in Malatya province. Methods: This is a cross-sectional survey. A multi-sage stratified probability-proportional-to-size cluster sampling methodology was used. A total of 823 pregnant women from sixty clusters were studied. Women were administered a questionnaire related with the subject and blood samples were drawn. Total blood count was performed within four hours and serum iron, folate and B12 vitamin were studied after storing sera at -20 C for six months. Results: Anemia prevalence was 27.1% (Hb < 11.0 gr/dl). Having four or more living children (OR = 2.2), being at the third trimester (OR = 2.3) and having a low family income (OR = 1.6) were determined as the independent predictors of anemia in pregnancy. Anemia was also associated with soil eating (PICA) in the univariate analysis (p < 0.05). Of anaemic women, 50.0% had a transferrin saturation less than 10% indicating iron deficiency, 34.5% were deficient in B12 vitamin and 71.7% were deficient in folate. Most of the anemias were normocytic-normochromic (56.5%) indicating mixed anemia. Conclusions: In Malatya, for pregnant women anemia was a moderate public health problem. Coexisting of iron, folate and B vitamin deficiencies was observed among anaemics. To continue anemia control strategies with reasonable care and diligence was recommended.Öğe The role of fecal calprotectin and lactoferrin in the diagnosis of necrotizing enterocolitis(Lippincott Williams & Wilkins, 2012) Selimoglu, Mukadder Ayse; Temel, Ismail; Yildirim, Cigdem; Ozyalin, Fatma; Aktas, Mumtaz; Karabiber, HamzaBackground: Early detection of necrotizing enterocolitis can improve the prognosis, however, there is not a reliable laboratory test to detect either newborns at risk for necrotizing enterocolitis development or those at early stages of the disease. Since fecal lactoferrin and fecal calprotectin are inflammatory markers of gastrointestinal diseases, it was hypothesized that both these biomarkers could be successfully used in the diagnosis of necrotizing enterocolitis. Methods: In a prospective study, fecal lactoferrin and fecal calprotectin concentrations of 14 newborns with necrotizing enterocolitis and consecutively admitted 40 healthy preterm, and 23 healthy full-term newborns were measured with enzyme-linked immunosorbent assay technique. Results: Mean fecal lactoferrin and fecal calprotectin were not different between preterm and full-term newborns (p = .235 and p = .845, respectively), or those who were diagnosed with necrotizing enterocolitis or not (p = .545 and p = .968, respectively). Prevalence of necrotizing enterocolitis was 1.51% (14 of 2734). Stage of the disease did not have a statistical effect on mean levels (p = .694 and p = .267, respectively). Mean fecal lactoferrin and fecal calprotectin levels were not different in the case of breast-feeding (p = .623 and p = .792, respectively). Conclusion: Neither fecal lactoferrin nor fecal calprotectin has a role in the identification of necrotizing enterocolitis, especially in early stages of the disease. Further studies on wider necrotizing enterocolitis series are needed for a more definite conclusion. (Pediatr Crit Care Med 2012; 13:452-454)Öğe Serum Fetuin-A Levels, QT Dispersion and P Dispersion in Dialysis Patients(Taylor & Francis Ltd, 2013) Taskapan, Mehmet Cagatay; Taskapan, Hulya; Comert, Melda; Temel, Ismail; Yagmur, Julide; Ulutas, OzkanBackground: This study aims to find association of fetuin-A with serum lipids, QT dispersion (QT-d), and P dispersion (P-d) in dialysis patients. Methods: Fetuin-A serum levels were assessed in 50 dialysis patients. Results: Serum fetuin-A levels were significantly associated with QT-d (r = 0.289, p = 0.044), P-d (r = 0.39, p = 0.005), total cholesterol (r = 0.526, p = 0.000), low-density lipoprotein cholesterol (LDL-C) (r = 0.456, p = 0.00), triglyceride (r = 0.360, p = 0.011) and highly sensitive C-reactive protein (hsCRP) (r = -0.347, p = 0.030). In step-wise multiple regression analysis including being on hemodialysis (HD), presence of diabetes mellitus (DM), total cholesterol, LDL-C, triglycerides, hsCRP, only total cholesterol (b = 0.419, p = 0.03), and hsCRP (b = -0.316, p = 0.03) proved to be independent predictors of serum fetuin-A levels. QT-d showed a linear correlation with total cholesterol (r = 0.309, p = 0.029), LDL-C (r = 0.304, p = 0.038), P-d (r = 0.390, p = 0.005), and fetuin-A levels (r = 0.289, p = 0.044). In multiple regression analyses, the independent predictor of QT-d was being on HD (b = -0.417, p = 0.004), whereas total cholesterol, LDL-C, presence of DM, serum fetuin-A levels, and P-d had no independent effect on corrected QT (QT-C). Being on HD and age were important determinants of P-d whereas presence of DM, total cholesterol, LDL-C, fetuin-A, and QT-d had no independent effect on P-d. Conclusions: Lower fetuin-A levels are associated with high hsCRP and low cholesterol levels in dialysis patients.Öğe Vitamin D deficiency, insulin resistance, serum adipokine, and leptin levels in peritoneal dialysis patients(Springer, 2013) Ulutas, Ozkan; Taskapan, Hulya; Taskapan, Mehmet Cagatay; Temel, IsmailAssociations between 25 hydroxy vitamin D [25(OH)D], adipokines levels, and insulin resistance have been reported. The aim of this study was to explore the effects of cholecalciferol supplementation on vitamin D levels, insulin resistance, leptin, and adiponectin levels in vitamin D-deficient peritoneal dialysis (PD) patients. In nineteen vitamin D-deficient PD patients, who were treated with cholecalciferol, fasting serum glucose, insulin, adiponectin, leptin, 25(OH)D and parathyroid hormone (PTH) were measured before and after cholecalciferol replacement therapy. Eighteen (94.7 %) PD patients with vitamin D deficiency were receiving active vitamin D compounds (alphacalciferol) for PTH control. Alphacalciferol dosing was kept constant during treatment with cholecalciferol. While mean 25(OH)D significantly increased from (10.2 +/- A 4.9 ng/ml) to (82.9 +/- A 56.5 ng/ml) (p < 0.05), mean homeostatic model assessment-insulin resistance index significantly decreased from (4.6 +/- A 3.6) to (2.8 +/- A 2.0) after cholecalciferol replacement therapy (p < 0.05). Serum leptin levels (12.9 +/- A 17.6 ng/ml) significantly increased (18.1 +/- A 19.5 ng/ml) (p < 0.05), while there was no change in serum adiponectin, calcium, and phosphate after vitamin D replacement. Serum PTH levels significantly decreased from 551.9 +/- A 276.6 pg/ml to 434.0 +/- A 273.4 ng/ml. Cholecalciferol replacement therapy significantly decreases PTH levels and insulin resistance. The results of this study need to be confirmed in larger clinical trials.
