State anxiety before and after chemotherapy did not vary among groups. The authors compared trait anxiety values before and after chemotherapy and found a significant difference in the lavender group. In addition, a significant change in PSQI measurements before and after chemotherapy was observed.

Öz: Aminoglikozidler, günümüzde klinik uygulamalarda sık olarak kullanılmaktadır. Gentamisin, gram (-) bakteriyel enfeksiyonların tedavisinde kullanılan aminoglikozid türevi bir antibiyotiktir. Aminoglikozid kullanımının kısıtlayıcı en önemli özelliği toksisiteleridir. Gentamisin testiste yapısal ve sitotoksik değişiklikler ortaya çıkarmaktadır. Hücre ve dokular, oluşan bu toksik etkilerden C vitamini gibi antioksidanlarla korunabilirler. Çalışmamızda gentamisinin sıçan testisleri üzerindeki toksik etkisi üzerine C vitaminin rolünü araştırmayı amaçladık. Bu çalışmada, 28 adet Spraque-Dawley türü sıçan kullanıldı. Sıçanlar her grupta 7 erişkin erkek sıçan olacak şekilde kontrol, 5 mg/kg gentamisin, 5 mg/kg gentamisin + 200 mg/kg C vitamini ve 200 mg/kg C vitamini verilen grup olmak üzere dört gruba ayrıldı. Deney süresi sonunda sıçanlar anestezik madde ile uyutularak testis dokusu örnekleri alındı, vücut ve testis ağırlıkları ölçüldü ve karşılaştırmalar yapıldı. Sol testisler doku takip işlemi için Bouin çözeltisi içerisine, sağ testisler ise %10'luk nötral formalin içerisine alındı ve rutin histolojik işlemlerden sonra bloklandı. Elde edilen parafin bloklardan 3 μm kalınlığında seri kesitler alındı ve kesitler HematoksilenEozin (H-E) ve Periyodik Asit-Schiff + Hematoksilen (PAS + H) ile boyandı. Tüm kesitlerin DP 70 dijital kamera eklentili Olympus BX51 ışık mikroskobu (Olympus Corp. Tokyo, Japan) ile görüntülemesi yapıldı ve fotoğraflandı. Çalışma sonunda elde edilen bulgulara göre vücut ağırlıkları açısından gruplar arasında önemli fark gözlendi. Mikroskobik incelemelerde, gentamisinin testislerde önemli hasara yol açtığı ve bu hasarın gentamisin + C vitamini verilen gruplarda azaldığı gözlemlendi. Elde edilen bulgularla, gentamisinin testislerde meydana getirdiği toksik etkinin C vitamini verilmesiyle önlenebileceği sonucuna varıldı. Anahtar Kelimeler: gentamisin, C vitamini, sıçan, testis. Abstract: Aminoglycosides are commonly used in clinical practice today. Gentamicin, gram (-) used in the treatment of bacterial infection is an antibiotic of the aminoglycoside derivatives. The most important feature is the restriction of the use of aminoglycoside toxicity. Gentamicin in testes reveal the structural and cytotoxic changes. Cells and tissue can be protected from gentamicin toxicity from antioxidants such as vitamin C. Material and methods: In this study we aimed to investigate the role of vitamin C in the protection of rat testes from gentamicin toxicity. In our study 28 Sprague-Dawley rats were used in four groups of 7. Rats in each group of 7 male rats were controlled to 5 mg / kg of gentamicin, 5 mg / kg gentamicin + 200 mg / kg of vitamin C and 200 mg / kg of vitamin C. After the experiment, the body weight and testicles were measured and comparisons were made. For follow-up is left testes tissue taken up in Bouin solution, while the right testis was taken up in 10% buffered formalin for routine histological processing then tissue preparation. After the staining process was blocked. 3 μm sections taken f...

ObjectiveThe aim of this study to investigate the normal values of erythropoietin (EPO) and neuroprotective effects of quercetin and mannitol on EPO and hematocrit levels after acute severe traumatic brain injury (TBI) in rat model.MethodsA weight-drop impact acceleration model of TBI was used on 40 male Wistar rats. The animals were divided into sham (group I), TBI (group II), TBI+quercetin (50 mg/kg intravenously) (group III), and TBI+mannitol (1 mg/kg intravenously) (group IV) groups. The malondialdehyde, glutathione peroxidase, catalase, EPO, and hematocrit levels were measured 1 and 4 hour after injury. Two-way repeated measures analysis of variance and Tukey’s test were used for statistical analysis.ResultsThe malondialdehyde levels decreased significantly after administration of quercetin and mannitol compared with those in group II. Catalase and glutathione peroxidase levels increased significantly in groups III and IV. Serum EPO levels decreased significantly after mannitol but not after quercetin administration. Serum hematocrit levels did not change significantly after quercetin and mannitol administration 1 hour after trauma. However, mannitol administration decreased serum hematocrit levels significantly after 4 hour.ConclusionThis study suggests that quercetin may be a good alternative treatment for TBI, as it did not decrease the EPO levels.

Background/Aims: To assess the utility of the DR-70 immunoassay in the diagnosis of gastric cancer. Materials and Methods: A total of 29 patients with histologically proven malignant gastric tumor and 29 healthy blood donors were enrolled in this study. DR-70 immunoassay was performed using an enzyme-linked immunosorbent assay kit to quantify the serum levels of fibrin degradation products. Results: The DR-70 values in patients with gastric cancer significantly differed from the values in controls (p<0.0001). Receiver operating characteristic curve analysis revealed ≥1.45 µg/mL as the best cut-off value to distinguish between patients with gastric cancer and healthy controls. The area under the receiver operating characteristic curve was 0.871. Using ≥1.45 µg/mL as the cut-off value, the DR-70 immunoassay showed a good clinical performance with a sensitivity of 82.8% and a specificity of 79.3%. The positive predictive value was 80.0%, and the negative predictive value was 82.1%. Conclusion: The DR-70 immunoassay reliably differs between gastric cancer and healthy controls, promising to become a useful cancer detection tool in clinical practice.
