Non-alcoholic fatty liver disease (NAFLD) is an acquired metabolic disease of the liver caused by accumulation of triglycerides in the hepatocytes followed by necrobiotic inflammatory reaction, fibrosis, and even cirrhosis. The accumulation of fatty acids in consequence of insulin resistance lies in the background of the process; the next step of pathogenesis is activation of microsomal polysubstrate systems and the oxidative stress caused by the released free radicals. Obesity, insulin resistance, diabetes mellitus and hyperlipidaemia are important pathogenetic factors. Patients with cholelithiasis and with a history of diabetes mellitus are known to have complications of cholelithiasis more frequently in comparison to those without diabetes. Objective: The aim of the study was the observation of the incidence of cholelithiasis and its complications in patients with NAFLD, as well as the comparison of the incidence of cholelithiasis between healthy persons and patients with NAFLD. Method: Abdominal ultrasonographical findings of patients hospitalised at the authors’ department and of outpatients have been analysed. Patients with severe co-morbidity were excluded of the analysis. The patient population studied can be considered as a selected sample, since patients undergoing abdominal ultrasound examination attended the clinics because of various clinical complaints, and the majority of them were hospitalised at the department. Alcohol abuse was excluded with the help of history taking by several investigators. Gender distribution within each group was also analysed. The independence of the two examined variables was measured by the χ 2 test. Results: Steatosis was described in 38% of the examined patients; cholelithiasis was described in 16% of patients. Of patients diagnosed with steatosis, 16% had cholelithiasis or some of its complications. Non-alcoholic fatty liver disease has been diagnosed by ultrasonography in 33% of patients with cholelithiasis. The incidence of NAFLD among patients examined because of cholelithiasis and its complications is two times higher than the incidence of cholelithiasis among patients examined for NAFLD. Complications of cholelithiasis occurred more frequently among patients with NAFLD than in those without it. The χ 2 test has brought no significant result for the independence of cholelithiasis and NAFLD. Conclusion: The pathogenetic factors of non-alcoholic fatty liver disease may play a role in the development of cholelithiasis, and presumably the non-alcoholic fatty liver disease develops more quickly than cholelithiasis, upon the effect of the shared pathogenetic factors.

Abstract  

Polycrystalline titanium samples were oxidized in pure oxygen under a 75 torr pressure, at temperatures ranging from 400°C to 500°C, and for times up to 2 hrs. A similar treatment was applied to some single crystal samples, so as to show the relationship between the crystallite orientation and the oxidation rate. The oxide films were studied by means of radioanalytical techniques, such as nuclear microanalysis, electron diffraction and ESCA, in addition to most classical techniques such as optical and electron microscopy. The complementary side of these methods is showed. They permit us to determine the contamination of the metallic surface introduced by the polishing treatments, the oxidation rate at constant temperature, and the structure of the oxides which exists in the films. These ones are especially TiO2, Ti3O5, Ti2O3 and TiO.

Abstract  

An ion exchange method has been developed for the separation of uranium from trace level metallic impurities prior to their determination by inductively coupled plasma optical emission spectrometry (ICP-OES) in uranium materials. Selective separation of uranium from trace level metallic impurities consisting Cr, Co, Cu, Fe, Mn, Cd, Gd, Dy, Ni, and Ca was achieved on anion exchange resin Dowex 1 × 8 in sulphate medium. The resin (100–200 mesh, in chloride form) was packed in a small Teflon column (7.8 cm × 0.8 cm I.D.) and brought into sulphate form by passing 0.2 N ammonium sulphate solution. Optimum experimental conditions including pH and concentration of sulphate in the liquid phase were investigated for the effective uptake of uranium by the column. Uranium was selectively retained on the column as anionic complex with sulphate, while impurities were passed through the column. Post column solution was collected and analyzed by ICP-OES for the determination of metallic impurities. Up to 2,500 μg/mL of uranium was retained with >99% efficiency after passing 25 mL sample through the column at pH 3. Percentage recoveries obtained for most of the metallic impurities were >95% with relative standard deviations <5%. The method established was applied for the determination of gadolinium in urania–gadolinia (UO2–Gd2O3) ceramic nuclear fuel and excellent results were achieved. Solvent extraction method using tributylphosphate (TBP) as extractant was also applied for the separation of uranium in urania–gadolinia nuclear fuel samples prior to the determination of gadolinium by ICP-OES. The results obtained with the present method were found very comparable with those of the solvent extraction method.
