Öğe Effects of formaldehyde inhalation on humoral immunity and protective effect of Nigella sativa oil: An experimental study(Sage Publications Inc, 2016) Sapmaz, Hilal Irmak; Sarsilmaz, Mustafa; Godekmerdan, Ahmet; Ogeturk, Murat; Tas, Ufuk; Kose, EvrenAim: This study was carried out to determine the effects of formaldehyde (FA) inhalation on the humoral immunity of rats and the protective effect of Nigella sativa (NS) oil. Materials and Methods: The rats (n = 33) were divided into five groups, with five animals in the control group (FA-free air) and seven in the other four groups. Group FA I was exposed to FA (5 ppm), group FA NS I was treated with NS and exposed to FA (5 ppm), group FA2 was exposed to FA (10 ppm), and group FA + NS2 was treated with NS and exposed to FA (10 ppm). At the end of a 4-week study period, blood samples were collected. Enzyme-linked immunosorbent assay was used to determine the levels of serum total immunoglobulin A (IgA), total immunoglobulin M (IgM), total immunoglobulin G (IgG), and complement 3 (C3). Results: FA inhalation significantly increased serum IgA, IgM, and C3 levels and decreased serum IgG levels compared with the control group. NS administration decreased serum IgA, IgM, and C3 levels, which were induced by FA inhalation. Conclusion: FA inhalation significantly increased acute antibody responses and C3 levels in a dose-dependent manner compared with the control group. FA inhalation decreased the secondary immune response compared with the control group. Levels of acute antibody responses and complement following exposure to FA inhalation returned to normal following treatment with NS (immunoregulatory effect). However, NS did not affect the secondary immune response.Öğe Effects of lemon essential oil aroma on the learning behaviors of rats(Riyadh Armed Forces Hospital, 2010) Ogeturk, Murat; Kose, Evren; Sarsilmaz, Mustafa; Akpinar, Burhan; Kus, Ilter; Meydan, Sedat[Abstract Not Available]Öğe Hepatotoxic activity of toluene inhalation and protective role of melatonin(Sage Publications Inc, 2011) Tas, Ufuk; Ogeturk, Murat; Meydan, Sedat; Kus, Ilter; Kuloglu, Tuncay; Ilhan, Necip; Kose, EvrenThis study was designed to investigate the harmful effects of toluene inhalation in the liver of rats and possible protective effects of melatonin on these detrimental effects. For this purpose, 21 adult male Wistar-albino rats were randomly divided into three equal groups. Animals in group I were used as control. The rats in group II were exposed to toluene (3000 ppm/1 hour/day) for 4 weeks, while the rats in group III were treated with melatonin (10 mg/kg/day, intraperitoneally [ip]) plus toluene inhalation. At the end of the experimental period, liver and blood samples were taken from the decapitated animals. Serum aspartate aminotransferase (AST), alanine aminotransferase (ALT), alkaline phosphatase (ALP), total bilirubin and albumin levels were determined. Liver tissue sections were stained with routine histological methods and examined under the light microscope. In addition, the sections were immunohistochemically stained using avidin-biotin-peroxidase method for determination of apoptosis. The liver tissue activities of superoxide dismutase (SOD), glutathione peroxidase (GSH-Px), catalase (CAT) and malondialdehyde (MDA) levels were also measured. Toluene inhalation significantly increased serum ALT, AST and tissue MDA, and decreased serum albumin, but did not affect serum ALP, total bilirubin levels and tissue SOD, GSH-Px and CAT activity when compared with controls. The increases in tissue MDA and serum ALT and AST levels induced by toluene inhalation were significantly inhibited by melatonin treatment. In light microscopic observations of tissues from toluene-inhaled rats, massive hepatocyte degeneration, ballooning degeneration and mild pericentral fibrosis were observed. Bax immune reactivity was also increased significantly. Melatonin treatment decreased the balloon degeneration, fibrosis and Bax immune reactivity in the liver of toluene-inhaled rats. In view of the present findings, it is suggested that melatonin has hepatoprotective effects against toluene toxicity via primarily antioxidative properties.Öğe HSP70 immune reactivity and TUNEL positivity in the liver of toluene-inhaled and melatonin-treated rats(Sage Publications Inc, 2013) Tas, Ufuk; Ogeturk, Murat; Kuloglu, Tuncay; Sapmaz, Hilal Irmak; Kocaman, Nevin; Zararsiz, Ismail; Sarsilmaz, MustafaToluene is a clear, colorless and volatile hydrocarbon that is metabolized in liver, produced free oxygen radicals and can mediate cellular damage. Melatonin which is a pineal gland hormone is a very potent antioxidant. It can make the cellular membrane more durable against oxidative attacks and protect nuclear DNA from oxidative damage. This study aimed to investigate heat shock protein (HSP)70 immune reactivity and terminal deoxynucleotidyl transferase-mediated dUTP nick end labeling (TUNEL) positivity (apoptotic activity) in the liver of toluene-inhaled and melatonin-treated rats. A total of 21 adult male Wistar albino rats were divided at random into 3 equal groups. Animals in group I were designated as control. The rats in group II were exposed to toluene (3000ppm/1h/day) for 30 days, while the rats in group III were treated with melatonin (10mg/kg/day, intraperitoneally) plus toluene inhalation. At the end of the 30-day experimental period, all rats were killed by decapitation. Then the liver tissues of rats were removed and tissue specimens were embedded in paraffin blocks. The specimens were stained with periodic acid-schiff (PAS) following routine histological procedures. Sections obtained from paraffin blocks were used for immune detection of TUNEL and HSP70. In light microscopic observations of tissues from toluene-inhaled rats, massive hepatocyte degeneration, ballooning degeneration and decreased PAS positivity were observed. Increased TUNEL positivity and HSP70 immune reactivity were determined in toluene-inhaled group and melatonin treatment decreased all these adverse effects.Öğe The Relationship between Anthropometric Measurements and Modified Mallampati Test in Patients with Chronic Obstructive Pulmonary Disease(Wolters Kluwer Medknow Publications, 2022) Cuglan, Songul; Kose, Evren; Kylyc, Talat; Ogeturk, Murat; Senol, Deniz; Ozbao, Davut; Colak, CemilContext: The modified Mallampati test (MMT) is one of the most common examination methods to predict possible intubation problems. Aim: The present study aims to investigate the relationship between anthropometric measurements and the MMT in patients with chronic obstructive pulmonary disease (COPD) during the exacerbation period (COPD-E) and stable period (COPD-S). Materials and Methods: The present study included two groups of participants that consisted of 107 healthy individuals in the control group and 107 patients who were diagnosed with COPD (patient group). Two measurements were taken from the patients during the exacerbation and stable periods. The MMT, body mass index (BMI), face height, thyromental distance, and sternomental distance were measured and recorded. Statistical Analysis Used: Data collected were analyzed using the SPSS Statistics for Windows, version 22.0. Results: In the COPD-E period, the MMT score increased, whereas the face height value decreased (P = 0.030). During the COPD-S period, it was found that the higher BMI values were related to higher MMT scores (P = 0.025). The MMT score increased significantly during the COPD-S period, whereas the thyromental distance values decreased (P = 0.034). Conclusion: It is considered that the low face height value in the COPD-E period, the increase in the BMI, and the decrease in the thyromental distance in the COPD-S period could increase the difficult intubation possibility. The results of the present study which may lead to progression in the COPD database would contribute to the clinicians.
