| 1 | Hepatic fibrosis in biliary-obstructed rats is prevented by Ginkgo biloba treatment显示文摘AIM: To assess the antioxidant and antifibrotic effects of long-term Ginkgo biloba administration on liver fibrosis induced by biliary obstruction in rats.METHODS: Liver fibrosis was induced in male Wistar albino rats by bile duct ligation and scission (BDL). Ginkgo administered for 28 d. At the end of the treatment period,all rats were killed. Serum aspartate aminotransferase (AST),alanine aminotransferase (ALT), and lactate dehydrogenase (LDH) levels were determined to assess liver functions and tissue damage, respectively. Tumor necrosis factor-α (TNF-α) was also assayed in serum samples. Liver tissues were taken for determination of the hepatic malondialdehyde (MDA) and glutathione (GSH) levels,myeloperoxidase (MPO) activity and collagen content.Production of reactive oxidants was monitored by chemiluminescence (CL) assay. Serum AST, ALT, LDH, and TNF-α levels were elevated in the BDL group as compared to control group and were significantly decreased by EGb treatment.RESULTS: Hepatic GSH level, depressed by BDL, was elevated back to control level in EGb-treated BDL group.Increase in tissue MDA level, MPO activity and collagen content due to BDL were also attenuated by EGb treatment.Furthermore, luminol and lucigenin CL values in BDL group increased dramatically compared to control and reduced by EGb treatment.CONCLUSION: Our results suggest that Ginkgo biloba protects the liver from oxidative damage following BDL in rats. This effect possibly involves the inhibition of neutrophil infiltration and lipid peroxidation; thus, restoration of oxidant and antioxidant status in the tissue. | Gksel pener Levent Kabasakal Meral Yüksel Nursal Gedik Ynci Alican | 2005 | World Journal of Gastroenterology2005，11，35： | 7 |
| 2 | One-step electrochemical reduction of stibnite concentrate in molten borax显示文摘In this study,antimony production from a stibnite concentrate(Sb2S3)was performed in one step using a molten salt electrolysis method and borax as an electrolyte.Electrochemical reduction of the stibnite concentrate was performed at 800℃under galvanostatic conditions and explained in detail by the reactions and intermediate compounds formed in the borax.The effects of current density(100 800 mA cm^-2)and electrolysis time(10 40 min)on cathodic current efficiency and antimony yields were systematically investigated.During the highest current efficiency,which was obtained at 600 mA cm^-2,direct metal production was possible with 62%cathodic current efficiency and approximately 6 kWh/kg energy consumption.At the end of the 40-min electrolysis duration at 600 mA cm^-2 current density,antimony reduction reached 30.7 g and 99%of the antimony fed to the cell was obtained as metal. | Levent Kartal Mehmet Baris Daryal Güldem Kartal Sireli Servet Timur | 2019 | International Journal of Minerals,Metallurgy and Materials2019，26，10： | 6 |
| 3 | Comparison of long-term results of trabeculectomy to treat pseudoexfoliative glaucoma and primary open angle glaucoma显示文摘AIM: To compare the long term outcome of trabeculectomy in patients with pseudoexfoliative glaucoma(PEG) and primary open angle glaucoma(POAG) in terms of surgical success. METHODS: The success of the trabeculectomy was evaluated by three criteria. Criterion A: intraocular pressure(IOP) ≤21 mm Hg and decrease in IOP ≥20%; Criterion B: IOP ≤18 mm Hg and decrease in IOP ≥30%; Criterion C: IOP ≤15 mm Hg and decrease in IOP ≥50%. Patients that met these criteria without medical treatment were considered to be completely successful, while those that met these criteria with medical treatment were considered partially successful. Significance levels of differences between the POAG and PEG groups in the Kaplan-Meier survival curves were calculated with the log-rank test. RESULTS: Sixty-four eyes from 64 patients with PEG and 51 eyes from 51 patients with POAG were evaluated. No significant differences were detected between the PEG and POAG groups according to full or partial success relative to each of the three criteria(A: P=0.73, 0.32; B: P=0.73, 0.31; C:P=0.90, 0.27). CONCLUSION: There is no difference in the long-term success of trabeculectomy between PEG and POAG patients whose clinical characteristics are otherwise the same. | Vuslat Pelitli Gürlü Hande Gürlü Altan Ozal Omer Benian Levent Alimgil | 2018 | International Journal of Ophthalmology(English edition)2018，11，1： | 3 |
| 4 | Prevalence of microscopic colitis in patients with diarrhea of unknown etiology in Turkey显示文摘AIM: To investigate the prevalence and demography of microscopic colitis in patients with diarrhea of unknown etiology and normal colonoscopy in Turkey. METHODS: Between March, 1998 to July, 2005, 129 patients with chronic non-bloody diarrhea of unexplained etiology who had undergone full colonoscopy with no obvious abnormalities were included in the study. Two biopsies were obtained from all colonic segments and terminal ileum for diagnosis of microscopic colitis. On histopathologic examination, criteria for lymphocytic colitis (intraepithelial lymphocyte ≥ 20 per 100 intercryptal epithelial cells, change in surface epithelium, mononuclear infiltration of the lamina propria) and collagenous colitis (subepithelial collagen band thickness ≥ 10 μm) were explored. RESULTS: Lymphocytic colitis was diagnosed in 12 (9%) patients (Female/Male: 7/5, mean age: 45 year, range: 27-63) and collagenous colitis was diagnosed in only 3 (2.5%) patients (all female, mean age: 60 years, range: 54-65).CONCLUSION: Biopsy of Turkish patients with the diagnosis of chronic non-bloody diarrhea of unexplained etiology and normal colonoscopic findings will reveal microscopic colitis in approximately 10% of the patients. Lymphocytic colitis is 4 times more frequent than collagenous colitis in these patients. | Levent Erdem Sadιk Yιldιrιm Nihat Akbayιr Banu Yιlmaz Necati Yenice Orhan Sami Gültekin nder Peker | 2008 | World Journal of Gastroenterology2008，14，27： | 2 |
