Öğe Aquaporin 1, Aquaporin 3 and Aquaporin 5 expression and EGFR mutation in malignant pleural mesotheliomas: an imunohistochemical and molecular study(Taylor & Francis Ltd, 2017) Alabalik, Ulas; Turkcu, Gul; Keles, Ayse Nur; Ibiloglu, Ibrahim; Urakci, Zuhat; Buyukbayram, HuseyinMalignant pleural mesothelioma is a rare and fatal malignancy. This disease is, unfortunately, at its advanced stage when it is diagnosed. Survival time is usually not more than a few months. The aim of this study was to analyse the expression of Aquaporin 1, Aquaporin 3 and Aquaporin 5 in malignant pleural mesotheliomas and to explore the relationship of these levels of expression with epidermal growth factor receptor (EGFR) gene mutation and prognostic parameters. In this study, 60 cases diagnosed as malignant pleural mesothelioma among the pleural biopsy materials in the archives of the Pathology Department of Medical Faculty of Dicle University in 2003-2013 were evaluated. The tissues were stained immunohistochemically with antibodies against Aquaporin 1, Aquaporin 3 and Aquaporin 5, and the existence of EGFR mutation was investigated in the tissues by real-time polymerase chain reaction (PCR). The obtained results showed expression of Aquaporin 1, Aquaporin 3 and Aquaporin 5 in varied amounts in malignant pleural mesotheliomas. However, no significant relation was obtained thus far between the expression levels of these aquaporins and the prognostic parameters. No mutations were detected in the EGFR gene exons 18-21 by using real-time PCR. It could be suggested that although Aquaporin 1, Aquaporin 3 and Aquaporin 5 are expressed in malignant pleural mesothelioma, they do not have any effect on the prognostic parameters. Mutations in different domains of EGFR gene, other than exons 18-21, should be sought to develop new targeted treatments.Öğe Atypical cutaneous features in adult onset Still's disease(Wolters Kluwer Medknow Publications, 2014) Akkurt, Zeynep Meltem; Bozkurt, Mehtap; Ucmak, Derya; Turkcu, Gul; Ucak, HaydarAdult onset Still's disease is a rare but potentially serious disease. We present five cases of adult-onset Still's disease seen by us over a period of one year. The patients were all females and 28-39 years of age. Symptoms had been present for 2-6 weeks in three patients. The other two had been on a few years' follow-up for rheumatoid arthritis before the onset of rashes and fever. The patients had persistent erythematous maculopapular eruptions on face, body and extremities, with moderate to severe pruritus and/or a burning sensation that decreased their quality of life. The typical evanescent rash was not observed. High ferritin values were detected in all the patients and total serum IgE was increased in two. All the patients were started on oral prednisolone (0.5-1.0 mg/kg/day), and methotrexate (10-15 mg/week) had to be added in three patients. One patient was started on tocilizumab due to recalcitrant disease and one was lost to follow-up. Further investigation and classification of the various atypical cutaneous findings in adult-onset Still's disease is necessary.Öğe Caffeic Acid Phenethyl Ester Protects Kidneys against Acetylsalicylic Acid Toxicity in Rats(Taylor & Francis Ltd, 2012) Bozkurt, Yasar; Bozkurt, Mehtap; Turkcu, Gul; Sancaktutar, Ahmet Ali; Soylemez, Haluk; Penbegül, Necmettin; Atar, MuratAim: The aim of this study was to investigate the protective effect of caffeic acid phenethyl ester (CAPE) on acetylsalicylic acid (ASA)-induced renal damage in rats. Materials and methods: A total of 40 rats were randomly divided into five groups, with eight rats in each group-group 1: control, not receiving any medication; group 2: ASA (50 mg/kg/day); group 3: ASA (50 mg/kg/day) + CAPE (20 mu g/kg/day); group 4: ASA (100 mg/kg/day); and group 5: ASA (100 mg/kg/day) + CAPE (20 mu g/kg/day). ASA and CAPE were given via orogastric gavage for 5 days. The total oxidant status (TOS), total antioxidant capacity (TAC), and paraoxonase-1 (PON-1) activity of the blood samples and kidney tissues were determined. Histopathological examinations of the kidneys were performed using light microscopic methods. Results: The TOS level in the serum of rats and kidney tissues given ASA (groups 2 and 4) significantly increased, but the levels of TAC and PON-1 in these tissues significantly decreased in group 4 when compared with the control rats (p < 0.05). The levels of TAC and PON-1 in the kidney tissues increased and the levels of TOS decreased in the CAPE treatment groups (groups 3 and 5) when compared with the rats in the no CAPE treatment groups (groups 2 and 4). The PON-1, TAC, and TOS values reverted to normal levels in group 5 when compared to group 4 (p < 0.05). These results were supported by histopathological observation. Conclusion: Oxidative stress plays an important role in ASA-induced nephrotoxicity, and CAPE may protect against ASA-induced nephrotoxicity in rats.Öğe Can aquaporins be used as diagnostic and prognostic markers for uterine smooth muscle tumours?(Taylor & Francis Ltd, 2017) Alabalik, Ulas; Turkcu, Gul; Keles, Ayse Nur; Ibiloglu, Ibrahim; Ozler, Ali; Urakci, Zuhat; Buyukbayram, HuseyinGenerally, uterine leiomyosarcoma is easily diagnosed. However, uterine smooth muscle tumours which show atypical histological features and unusual growth patterns may mimic malignancy and may not be easily diagnosed. In this study, our aim is to show the expressions of Aquaporin3, Aquaporin7 and Aquaporin9 in uterine smooth muscle tumours, and to investigate if aquaglyceroporins can be used as diagnostic and prognostic markers to start rapidly an appropriate treatment for patients with these tumours in order to extend the survival time. We determined that there had been 74 patients diagnosed with uterine smooth muscle tumours. We divided patients into four groups based on the diagnosis: bizarre leiomyoma, smooth muscle tumour of uncertain malignant potential, leiomyosarcoma and leiomyoma. Aquaporin3, Aquaporin7 and Aquaporin9 were detected by using monoclonal anti-Aquaporin3, anti-Aquaporin7 and anti-Aquaporin9 antibodies, respectively. In leiomyosarcoma group, we observed a statistically significant relation of Aquaporin3 expression with survival time, grade, stage, mitotic index and Ki-67 score. A significant relation of both Aquaporin7 and Aquaporin9 expressions with survival time, grade, stage was not statistically detected in leiomyosarcoma group. The decrease of Aquaporin3 expression can be used as important diagnostic and prognostic marker. Aquaporin7 and Aquaporin9 expressions cannot be used as diagnostic and prognostic markers.Öğe Carvacrol prevents methotrexate-induced renal oxidative injury and renal damage in rats(Canadian Soc Clinical Investigation, 2014) Bozkurt, Mehtap; Em, Serda; Oktayoglu, Pelin; Turkcu, Gul; Yuksel, Hatice; Sariyildiz, Mustafa A.; Caglayan, MehmetPurpose: The purpose of this study was to investigate the effect of carvacrol (CAR) on methotrexate (MTX)-induced renal damage in rats. Methods: Twenty-four male rats were equally divided into three groups: group I, control treatment; group II, MTX-treated; and group III, MTX+CAR-treated. A single dose of CAR (73 mg/kg) was administered intraperitoneally to group III on the first day of the experiment and a single dose of MTX (20 mg/kg) was administered intraperitoneally to groups II and III on the second day of the experiment. Blood samples and kidney tissue were obtained from each animal on day 8 for the measurement of malondialdehyde (MDA), total oxidant status (TOS), total antioxidant status (TAS), and oxidative stress index (OSI). Light microscopy was used for histopathological examination of kidney specimens. Results: MDA, TOS and OSI levels were significantly greater in the group receiving MTX alone relative to the control animals, while the TAS level was significantly reduced in the MTX group compared with the control group. The administration of CAR was associated with signicantly decreased MDA, TOS, and OSI levels and increased TAS levels relative to the rats treated with MTX alone. Animals treated with CAR exhibited decreased tubular degeneration and architectural impairment relative to animals treated with MTX alone; however, the difference in histological scores did not meet the threshold of statistical significance. Conclusions: MTX treatment results in oxidative damage to the rat kidney; damage which is partially abrogated by the administration of CAR.Öğe COMPARISON OF SKIP EXPRESSION IN MALIGNANT PLEURAL MESOTHELIOMAS WITH KI-67 PROLIFERATION INDEX AND PROGNOSTIC PARAMETERS(Vesalius Univ Medical Publ, 2016) Turkcu, Gul; Alabalik, Ulas; Keles, Ayse Nur; Ibiloglu, Ibrahim; Kucukoner, Mehmet; Sen, Hatice Selimoglu; Buyukbayram, HuseyinWe aimed to determine the presence of SKI-interacting protein (SKIP) expression in malignant pleural mesothelioma (MPM) and its effect on prognosis by investigating SKIP correlation with the Ki-67 proliferation index and prognostic parameters. Pathological preparations of the patients diagnosed with MPM between 2006 and 2012 were evaluated. Immunohistochemical analyses were performed to evaluate the expression of SKIP and the Ki-67 proliferation index. Correlations between SKIP expression, clinicopathological factors and survival were investigated. Survival data were calculated using the Kaplan-Meier method, and Cox regression analysis was used to evaluate the prognostic value of the variables. In total, 52 patients were evaluated in the study; 36 of them were male and 16 were female. The mean age of the patients was 62.3 +/- 12.2 years. The median overall survival period was 8.5 months. Factors negatively affecting general survival in the univariate analysis included high SKIP expression, Ki-67 proliferative index over 30%, presence of non-epithelioid type MPM and stage III-IV disease (p < 0.05). Cox regression analysis revealed that high SKIP expression, high Ki-67 proliferative index and presence of non-epithelioid type MPM are independent factors that affect the survival rate. Higher SKIP expression is associated with poor prognosis in MPM.Öğe Congenital-infantile fibrosarcoma of the ileocecal region: the first case presentation(Springer, 2016) Zeytun, Hikmet; Okur, Mehmet Hanifi; Basuguy, Erol; Arslan, Serkan; Aydogdu, Bahattin; Turkcu, Gul; Arslan, Mehmet SerifInfantile fibrosarcoma is a very rare soft tissue tumor that originates most commonly in the body and extremities. We present a neonate with an infantile fibrosarcoma that originated in the ileocecal region and was detected incidentally without symptoms. This is the first case of fibrosarcoma reported in the ileocecal region.Öğe Cryoglobulin and antineutrophil cytoplasmic antibody positive cutaneous vasculitis due to propylthiouracil(Wolters Kluwer Medknow Publications, 2014) Akkurt, Zeynep Meltem; Ucmak, Derya; Acar, Gurbet; Beysel, Selvihan; Turkcu, Gul; Ucak, Haydar; Akdeniz, Sedat[Abstract Not Available]Öğe Dexmedetomidine and Magnesium Sulfate: A Good Combination Treatment for Acute Lung Injury?(Taylor & Francis Inc, 2019) Guzel, Abdulmenap; Dogan, Erdal; Turkcu, Gul; Kuyumcu, Mahir; Kaplan, Ibrahim; Celik, Feyzi; Yildirim, Zeynep BaysalObjectives: In this study, we aimed to investigate the therapeutic effects of magnesium sulfate (MgSO4) and dexmedetomidine (dex) in a model of acute lung injury (ALI). We determined whether concomitant administration decreased the inflammatory effects of hydrochloric acid (HCl)-induced ALI in a synergistic manner. Materials and Methods: In this study, 42 Sprague-Dawley rats were randomized into six groups: Group S (saline), Group SV (saline + mechanical ventilation), Group HCl (HCl), Group Dex (Dex), Group Mag (MgSO4), and Group DM (Dex + MgSO4). All groups except Group S were mechanically ventilated prior to HCl-induced ALI. Saline or HCl was administered via tracheostomy. Prior to treatment, HCl was administered to Group HCl, Group Dex, Group Mag, and Group DM to induce ALI. Dex and MgSO4 were administered intraperitoneally. The rats were monitored for 4 h after treatment to measure oxidative stress parameters in blood, and prolidase enzyme activity. Lung tissue damage were determined via histopathology. Results: A significant increase in heart rate and rapid desaturation was observed in HCl-administered groups. Treatment administration decreased the pulse values. Increased saturation values and decreased oxidative stress indices were observed in groups that were subsequently administered Dex and MgSO4. Serum prolidase activity increased significantly in Group HCl. Severe pathological findings were detected following HCl-induced ALI. Group Mag showed greater improvement in the pathology of HCl-induced ALI than did Group Dex. Administration of both Dex and MgSO4 did not improve the pathological scores. Conclusions: The antioxidant and anti-inflammatory effects of Dex and MgSO4 ameliorated the detrimental effects of HCI-induced ALI. However, adverse effects on hemodynamics and lung damage were observed when the two drugs were administered together.Öğe Early-onset basal cell carcinoma(Turkish J Pediatrics, 2013) Turan, Enver; Yurt, Nurdan; Yesilova, Yavuz; Turkcu, GulBasal cell carcinoma (BCC) is a common skin cancer that is responsible for approximately 75% of non-melanoma skin cancers. BCC occurs on sun-exposed areas in fair-skinned individuals; frequency increases with age and peaks in the seventh decade of life. Although it usually occurs in the elderly population, it has been reported in children as well. Here, we present a case of BCC in an eight-year-old child without any predisposing characteristics.Öğe Effect of Caffeic Acid Phenethyl Ester on Intra-Abdominal Adhesion in Rats(Karger, 2013) Turgut, Abdulkadir; Sak, Muhammet Erdal; Turkcu, Gul; Ozler, Ali; Soydinc, Hatice Ender; Evsen, Mehmet Siddik; Evliyaoglu, OsmanBackground: To determine the impact of caffeic acid phenethyl ester (CAPE) on abdominal adhesion formation after laparotomy. Methods: Forty female rats were allocated into four distinct groups on which laparotomy alone; laparotonny with traumatization of the uterine horns; laparotomy, traumatization of the uterine horns and intraperitoneal irrigation with saline, and laparotomy, traumatization of the uterine horns and intraperitoneal irrigation with CAPE were performed. After sacrifying the animals on the 14th postoperative day, histopathological examination and biochemical analysis were conducted to evaluate the formation of abdominal adhesions and antioxidant status. Results: In the CAPE group, total adhesion scores were significantly lower than in the control and saline groups. The CAPE group displayed less inflammation, giant cell formation, fibrosis and fibroblastic activity than the control group. On the other hand, the control group displayed higher total adhesion scores. Conclusion:The results of this study indicate that the administration of CAPE may have beneficial effects for the prevention of abdominal adhesion formation after laparotomy. Further clinical studies are mandatory to explore the actual therapeutic potential of CAPE. Copyright (C) 2013 S. Karger AG, BaselÖğe Effect of Estrogen Replacement Treatment on VEGF in Serum and Retina in Rats(Modestum Ltd, 2015) Yuksel, Harun; Turgut, Fethiye Gulden; Turkcu, Fatih M.; Ozkurt, Zeynep; Sahin, Muhammed; Yuksel, Hatice; Turkcu, GulVascular endothelial growth factor (VEGF) is a molecule implicated in the pathogenesis of several eye diseases. In this experimental study, we planned to evaluate the effects of surgical menopause and hormone replacement therapy on VEGF levels. Thus, we studied the effects of treatments involving estrogen, estrogen and progesterone (E/P) in combination, and genistein, which is a selective estrogen modulator, on serum VEGF levels and the expression of VEGF in the retinas of rats with surgical menopause. The rats were randomly divided into five groups. Bilateral ovariectomy (OVX) was performed in all groups except for the sham-operated group. estrogen, E/P, genistein or water (sham and control groups) treatments were given for 8 weeks through the orogastric catheter. Serum VEGF level and immunohistochemical staining of VEGF in retinal tissue were analyzed in each group. Serum VEGF levels were significantly higher in the OVX + estrogen and OVX + genistein groups than in the control and sham groups. It was also higher in the OVX + E/P group than in the sham and control groups; however, in this case, the difference was not statistically significant. The OVX + estrogen, OVX + E/P, and OVX + genistein groups exhibited increased VEGF staining in comparison with the control and sham groups. However, the difference was not statistically significant. The current study demonstrated that estrogen replacement treatment (ERT) leads to an increase in serum VEGF levels and progesterone plays a protective role in this increase. The ERT used in this study had no effect on VEGF expression in the retina.Öğe The effects of caffeic acid phenethyl ester in acute methanol toxicity on rat retina and optic nerve(Taylor & Francis Ltd, 2013) Sahin, Alparslan; Kaya, Savas; Turkcu, Gul; Cingu, Abdullah Kursat; Yuksel, Harun; Turkcu, Fatih Mehmet; Yuksel, HaticePurpose: We aimed to test caffeic acid phenethyl ester (CAPE) as an antidote for acute methanol (MeOH) toxicity and to compare it with ethanol. Methods: This study included five groups, each containing eight rats. The groups were control, methotrexate (MTX), MeOH, ethanol and CAPE. All rats except control group were treated with intraperitoneal (i.p.) MTX (0.3 mg/kg/d) for 7 d. At the 8th day of the experiment, i.p. injection of MeOH (3 g/kg) was administered in MeOH, ethanol and CAPE groups. Four hours after MeOH treatment, 0.5 g/kg ethanol was injected i.p. in ethanol group; 10 mu mol/kg CAPE i.p. in CAPE group; serum physiologic i.p. in other groups. After 8 h, rats were anaesthetized and sacrificed. Total anti-oxidant status (TAS), total oxidant status (TOS) were measured on the dissected and excised retina and optic nerve samples. Fellow eyes were used for histopathologic evaluation and the cell count of retinal ganglion cell (RGC) layer. In addition, interactions of alcohol dehydrogenase with CAPE, ethanol, MeOH and pyrazole derivatives were investigated. Results: Either CAPE or ethanol co-treatment decreased the TOS levels and increased the TAS levels compared to the MeOH group. MeOH treatment decreased the mean cell count in RGC layer. CAPE co-treatment significantly prevented cell loss (p=0.040). Besides, in silico calculations showed that binding affinity of CAPE to alcohol dehydrogenase was higher than those of MeOH, ethanol, and pyrazole derivatives were. Conclusion: This study demonstrated that CAPE treatment decreased the oxidative stress in acute MeOH intoxication in the retina and optic nerve; beside that, protected RGC layer histology. In silico, CAPE had higher affinity score than MeOH, ethanol, pyrazole and pyrazole derivatives in the case of interaction with alcohol dehydrogenase.Öğe Efficacy of N-Acetylcysteine on Wound Healing of Nasal Mucosa(Lippincott Williams & Wilkins, 2015) Yilmaz, Beyhan; Turkcu, Gul; Sengul, Engin; Gul, Aylin; Ozkurt, Fazil Emre; Akdag, MehmetPostoperative nasal mucosa healing is a highly complex and organized process, and the success rates of endoscopic sinus surgery and septoplasty surgeries are closely associated with the postoperative wound healing processes. In this experimental study, the authors' aim was to use histopathologic examination to investigate the effects of N-Acetylcysteine (NAC) on the wound healing of rat nasal mucosa after mechanical trauma. Twenty-one Sprague-Dawley rats were randomly divided into 3 groups: the nontreated group (N = 7), the control saline group (N = 7), and the NAC group (N = 7). No treatment was given to the nontreated group for 15 days. The control saline group received intraperitoneal injection of saline (2.5 mL/kg, intraperitoneal) for 15 days and the NAC group was intraperitoneally injected with NAC at a dose of 300 mg/kg/day for 15 days. At the beginning of the study, unilateral mechanical nasal trauma was induced with an interdental brush inserted through the right nostril in all rats. Samples were stained using hematoxylin and eosin solution, and were examined by a pathologist using a light microscope. The severity of inflammation was milder in the NAC group compared with that in the nontreated and saline groups (P < 0.05). The subepithelial thickness index was lower in the experimental group (P < 0.05). Goblet cell loss was reduced in the experimental group compared with the nontreated and saline groups (P < 0.05). NAC decreases inflammation and goblet cell loss. Therefore, NAC has potential beneficial effects on the wound healing of nasal mucosa in rats.Öğe Expression of interleukin-17 in lesions of erythema multiforme may indicate a role for T helper 17 cells(Termedia Publishing House Ltd, 2014) Akkurt, Zeynep Meltem; Ucmak, Derya; Turkcu, Gul; Yuksel, Hatice; Yildiz, Kenan; Arica, MustafaIntroduction: The aim of this study was to evaluate levels of interleukin (IL)-2, IL-6, IL-8, IL-10, IL-17A and interferon gamma (IFN-gamma) in the serum of patients with erythema multiforme (EM) and to search for the presence of IL-17-expressing cells in lesional samples of EM. Material and methods: A total of 32 patients (22 females and 10 males) diagnosed with EM of the minor or major type were included in the study. Levels of IL-2, IL-6, IL-8, IL-10, IL-17A and IFN-gamma in the serum were determined and compared with healthy controls. Biopsy specimens were stained with haematoxylin and eosin (HE) and monoclonal antibodies to CD4, CD8 and IL-17 for immunohistochemical examination. Results: IL-2, 6, 8 and 17A were significantly higher in the patient group (p = 0.016, p = 0.001, p = 0.004, p = 0.006, respectively) and levels of IL-10 were significantly lower than in the control group (p = 0.046). The cellular infiltrate in lesions of EM was composed mainly of CD4+ T lymphocytes. The presence of IL-17-expressing cells, at proportion of 5 to 50%, was observed in the infiltrate. Conclusions: The demonstration of IL-17-expressing cells in lesions of EM in this study has brought forth the assumption that Th17 cells may be involved in the pathogenesis of EM.Öğe Hypereosinophilia in Erythrodermic Psoriasis: Superimposed Scabies(Quadrant Healthcom Inc, 2014) Harman, Mehmet; Ucmak, Derya; Akkurt, Zeynep Meltem; Turkcu, GulScabies is a common ectoparasitic disease that can be diagnosed based on the presence of pruritus and typical clinical signs including burrows, vesicles, and erythematous papules. If a desquamative disease such as psoriasis precedes scabies, then the disease course may be altered. Pruritus may be absent and typical scabies lesions may be concealed due to the preexisting disease, resulting in delayed diagnosis. We present 2 cases of scabies in a brother and sister with erythrodermic psoriasis. In both cases peripheral hypereosinophilia suggested scabies. In patients with erythematous scaly inflammatory skin diseases who are treated with immunosuppressive agents, peripheral eosinophilia also could suggest scabies; therefore, a search for sarcoptic mites in skin scrapings should be undertaken.Öğe Institutional experience in the histopathological characteristics and frequency of gallbladder lesions(E-Century Publishing Corp, 2016) Turkcu, Gul; Alabalik, Ulas; Keles, Ayse Nur; Ibiloglu, Ibrahim; Hamidi, Arif; Ulger, Burak Veli; Buyukbayram, HuseyinPurpose: Our aim in this study is to retrospectively examine cases in which cholecystectomy was performed and to determine incidental cancer cases. Materials and methods: We retrospectively examined the pathology reports of 1841 patients who underwent surgeries in the general surgery clinic for the treatment of gallbladder diseases between March 2006 and May 2015 and whose gallbladder materials were examined after surgery. Age, gender, pathological diagnosis and presence of gallbladder stones were recorded. Results: The average age of the 1841 patients (male/female: 585/1256) evaluated in this study was 50.37 +/- 18.81 years (range: 2-97 years). Surgery for gallbladder disease was most commonly performed in the age range of 50-60 years. Chronic cholecystitis was the most common histopathological diagnosis (92.0%), followed by acute cholecystitis (5.1%), non-neoplastic lesions (1.74%), preneoplastic lesions (0.76%), carcinomas (0.33%) and lymphomas (0.1%). One or more gallbladder stones were detected in 955 patients. Of these, 93.4% and 4.1% patients were diagnosed with chronic cholecystitis and acute cholecystitis, respectively. Conclusion: Histopathological examination of gallbladder materials is important for identifying incidental benign and malignant tumours.Öğe Is montelukast as effective as N-acetylcysteine in hepatic injury due to acetaminophen intoxication in rats?(Elsevier Gmbh, 2016) Icer, Mustafa; Zengin, Yilmaz; Gunduz, Ercan; Dursun, Recep; Durgun, Hasan Mansur; Turkcu, Gul; Yuksel, HaticeThis study aims to investigate the acute protective effect of montelukast sodium in hepatic injury secondary to acetaminophen (APAP) intoxication. This study used 60 rats. The rats were grouped into 6 groups. The control group was administered oral distilled water 10 ml/kg, the APAP group oral APAP 1 g/kg, the montelukast sodium (MM) group oral MK 30 mg/kg, the acetaminophen + N-acetylcysteine (APAP + NAC) group oral APAP 1 g/kg, followed by a single dose of intraperitoneal NAC 1.5 g/kg three hours later, the acetaminophen + montelukast sodium (APAP+MK) group oral APAP 1 g/kg, followed by oral MK 30 mg/kg 3 h later, the acetaminophen + Nacetylcysteine + montelukast sodium (APAP + NAC + MM) group oral APAP 1 g/kg, followed by a single intraperitoneal NAC 1.5 g/kg plus oral MK 30 mg/kg 3 h later. Blood and liver tissue samples were taken 24 h after drug administration. Aspartate aminotransferase (AST), alanine aminotransferase (ALT), alkaline phosphatase (ALP), and total bilirubin were studied from the blood samples. Liver tissue samples were used for histopathological examination. Compared with the control group, serum AST and ALT activities were higher in the APAP and APAP + NAC groups. APAP + NAC, APAP + MK, and APAP + NAC + MM groups had reduced serum ALT and AST activities than the group administered APAP alone. APAP + MM and APAP + NAC + MK groups had a lower serum ALP activity than the control group. Histopathologically, there was a difference between the group administered APAP alone and the APAP + MK and APAP + NAC + MK groups. MK is as protective as NAC in liver tissue in APAP intoxication in rats. (C) 2015 Elsevier GmbH.

Only about 30 cases with extramedullary plasmacytoma of the skin are reported in the literature. Case Report: An 82-year-old male patient presented to our clinic with complaints of asymptomatic red nodular swelling and pain in the anterior chest wall. A dermatologic examination revealed multiple nodular lesions of varying sizes with a hard smooth surface and vivid red color. Serum protein and immunoglobulin electrophoresis, skeletal radiography, and bone marrow biopsy showed normal results in this patient. Here a rare case of multiple primary plasmacytoma localizing in the skin is reported.Öğe Nebivolol Ameliorates Hepatic Ischemia/Reperfusion Injury on Liver But Not on Distant Organs(Taylor & Francis Inc, 2015) Ulger, Burak Veli; Erbis, Halil; Turkcu, Gul; Ekinci, Aysun; Turkoglu, Mehmet Akif; Ekinci, Cenap; Yilmaz, Vural TanerIntroduction: Hepatic ischemia/reperfusion injury may occur after large tumor resection and liver transplantation procedures. Nitric oxide was shown to have protective effects on ischemia/reperfusion injury. Nebivolol is a compound that has been reported to improve nitric oxide release. We evaluated the effects of nebivolol in a rat liver ischemia/reperfusion model. Methods: A total of 40 rats were randomly divided into four groups (n = 10 each). Group I underwent only laparotomy, Group II was administered nebivolol and then underwent laparotomy, Group III underwent laparotomy and hepatic ischemia/reperfusion, and Group IV was administered nebivolol and then underwent laparotomy and hepatic ischemia/reperfusion. Serum AST, ALT, urea, and creatinine levels, and TAS and TOS levels of liver, lung, and kidney tissues were determined. Histopathological determination was also performed. Results: Nebivolol significantly reduced liver function tests in group IV, but it did not improve renal functions. Oxidative stress and abnormal histopathological findings were found to be reduced in liver tissue in group IV. Although the oxidative stress was increased after hepatic ischemia/reperfusion, nebivolol could not reduce the oxidative stress in kidney tissue. There were no significant differences between group III and group IV in terms of the histopathological changes in kidney tissue. There were no significant differences in lung tissue between the groups. Conclusions: The results of this study suggest that nebivolol has protective effects on liver but not on distant organs in a hepatic ischemia/reperfusion injury model. These experimental findings indicate that nebivolol may be useful in the treatment of hepatic ischemia/reperfusion injury.
