Öğe Blood and faecal lead levels in children with various functional gastrointestinal disorders(Ediciones Doyma S A, 2020) Sevinc, Nergiz; Bilici, Namik; Sevinc, Eylem; Dogan, ErkanIntroduction: To investigate the blood lead levels (BLLs) and faecal lead levels (FLLs) in children with various functional gastrointestinal disorders (FGIDs) and compare them with controls. Patients and methods: One hundred and 2 children with FGIDs defined by the Rome IV criteria, aged 4-18 years, and one hundred and 2 sex matched healthy children were enrolled in the study. Children with FGIDs were divided into 3 subgroups as functional constipation (FC) (n = 36), functional abdominal pain (FAP) (n = 36) and functional nausea (FN) (n = 30). The lead levels were measured using atomic absorption spectrometer. Results: The median BLLs in the FGIDs group was significantly higher than in controls (5.12 and 1.77 mu g/dL, respectively). The BLLs were above 5 mu g/dL in 51,9% of children with FGIDs. There was statistically significant difference in BLLs between FC subgroup and the other subgroups (FAP and FN) (P=.003, P<.001 respectively). The FLLs in the FGIDs group was significantly higher than in controls (28.08 and 0.01 mu g/g, respectively). There was no significant difference in FLLs between FC subgroup and the other subgroups (P=.992, P=.989 respectively). No significant relation found between BLLs and FLLs of the FGIDs group (P =.123). Conclusion: This study revealed that children with FGIDs had higher BLLs and FLLs than controls and also more than half of children with FGIDs had BLLs >= 5 mu g/dL which is toxic level. These results might revive the question of whether or not clinician need to evaluate routine BLLs in children with FGIDs. (C) 2020 Asociacion Espanola de Pediatria.

The main risk is environmental factors and nutrition. Arsenic (As) is commonly found in the earth's crust. As is an essential element that can form many organic compounds. In children, it causes diarrhea, gums, tongue lesions, diabetes, conjunctivitis, ocular opacity, and impaired immune response. It also causes low growth, mental retardation, and neurological problems. It is also known as the cause of many cancers that originate at an early age. Regionally, there is an iron and steel industry for almost a century. According to the Rome IV criteria, the blood and stools of 50 children aged 6-18 years, male and female, living in our province with functional gastrointestinal disease (FGD), were screened for As, and compared with the Healthy group (control) of 30 children. The results were evaluated with the Mann-Whitney Rank Sum Test. When blood and stool As values in males were compared with control samples, a high level of significance (p = 0.001) was found between both blood and stool As values in sick males and the control group (p < 0.005). In females, blood and stool As median values were also highly significant when compared with the control group (p = 0.001). According to these data, when the sick children (children with male and female gender) are compared with the healthy ones, the difference is highly significant (p < 0.005). High blood As levels in children indicate environmental pollution. It can be said that blood As levels are high as a result of food, water, and inhaler exposure. The presence of a high level of significant difference in stool means that the amount of As is high in the foods consumed daily. High levels of As are in blood and stools; It was evaluated that FGD could be the cause of nausea, diarrhea, vomiting, and colic. The increase in blood and stool As values due to environmental pollution is an important reason for FGD. For diseases of uncertain cause (such as FGD) resulting from chronic As exposure, blood and especially stool As values are more significant than urinary As levels. In conclusion, As a diagnostic criterion, it was concluded that blood and stool As values are an important marker in children with functional abdominal pain with other metals.Öğe Cyclophosphamide induced oxidative stress, lipid per oxidation, apoptosis and histopathological changes in rats: Protective role of boron(Elsevier Gmbh, 2020) Cengiz, Mustafa; Sahinturk, Varol; Yildiz, Songul Cetik; Sahin, Ilknur Kulcanay; Bilici, Namik; Yaman, Suzan Onur; Altuner, YilmazBackground: Cyclophosphamide (CP) is an alkylating chemotherapeutic drug used in the treatment of many types of cancer. However, as with other chemotherapeutic drugs, the use of CP is limited by the damage to healthy tissues such as testes, bladder and liver as well as cancerous tissue. Boron (B) is a trace element with many biological properties such as antioxidant, anti-apoptotic and anti-lipid per oxidation. Methods: This current study aims to determine protective effects of B on CP induced testicular toxicity. The rats were divided into 4 groups (control, CP, B and B plus CP groups). The testes of experimental animals were taken for histological, apoptotic markers and biochemical analysis. Results: The damage to some seminifer tubules, loss of typical appearance, thinning of seminifer epithelium and relative enlargement of the tubule lumen were watched in testis of the group that administrated CP. Moreover, Bcl-2, TAC and GSH levels decreased while TOC, OSI, MDA, Bax and Caspase-3 levels increased. On the other hand, pretreatment limited to B in the B plus CP group, testicular tissue improved. In addition, Bcl-2, GSH, TAC levels increased, Bax, MDA, TOC, OSI and caspase-3 levels decreased. Conclusion: B significantly reduced testicular lipid per-oxidation and strengthened antioxidant defenses. Our results showed that pre-treatment B can protect rat testis against CP-induced testicular damage owing to its anti-lipid per oxidation, anti-oxidant and anti-apoptotic properties.Öğe Değişik işleme proselerinin broilerlerde kullanilan lasalosit kalinti düzeylerine etkisi(2015) Bilici, NamikKanatlı Koksidiyozisi eimeria türlerinin neden olduğu önemli bir protozon hastalığıdır. Kanatlı endüstrisinde önemli ekonomik kayıplara yol açmaktadır. Koksidiyozisin kontrölünde nikarbazin, halofuginon, robenidin, diklazuril, monensin, salinomisin, narasin, lasalosit ve maduramisin gibi ilaçlar kullanılmaktadır. Kullanılan ilaçların kalıntıları izlenmesi ve gerekli önlemlerin alınması insan sağlığı açısından büyük bir önem taşımaktadır. Bu çalışmada İstanbul'da tüketime sunulan tavuk eti ve yumurtalardan aldığımız 150'şer adet numune de lasalosit kalıntı ve düzey izlemesi yapılmıştır. Genel olarak broilerlerdeki (tavuk) yedirme koşullarında lasalosit 75-125 µg/g ile sınırlandırılmıştır. Bu şartlarda yapılan yedirme denemeleri sonrasında 1. 3. ve 5. ve 7. günlerde alınan dokularda analizler yapılmış, 1. 3. 5. gün dokularındaki lasalosit kalıntı düzeyi önemli bulunmuştur. Kalıntı miktarı yüksek olan 1. 3. ve 5. gün dokuları kızartma, haşlama, +4°C muhafaza ve dondurmaya işleme ve depolama proseslerine tabi tutulmuştur. Sonuç olarak lasalosit giderek hızla azalan bir rezidüye sahip olduğu ve dokudaki kalıntılarının ısıl işlemlerden etkilendikleri tespit edilmiştir
