The gastroesophageal reflux and/or peptic ulcer diseases are clinical conditions that occur usually accompanied of symptomatic pain. Lansoprazole, a proton pump inhibitor class drug is widely used in clinical practice for treatment of these diseases. However, its efficacy can be improved by combining with spasmolytic and/or visceral analgesic such as hyoscine butylbromide. Since hyoscine butylbromide is barely absorbed and exerts some local effects at gastrointestinal tract which may modify the absorption of lansoprazole, it is important to establish if there is a pharmacokinetic interaction after the oral concomitant administration of both drugs. For this objective, twenty-five subjects received under a crossover design an oral administration of lansoprazole (15 mg) plus placebo or a fixed-dose combination with hyoscine butiylbromide (15 mg + 10 mg, respectively). Plasma samples were obtained at different times during 10 hours. Lansoprazole plasma concentrations were determined by a high performance liquid chromatography method coupled to tandem mass spectrometry. Fixed-dose combination was well tolerated. Lansoprazole pharmacokinetic parameters were: Cmax 621.81 ± 212.79 and 450.38 ± 192.14 ng/mL;AUC0-t 1941.36 ± 845.57 and 1454.66 ± 757.28 ng·h/mL;tmax 2.83 ± 0.99 and 3.40 ± 1.82h;t1/2 1.35 ± 0.39 and 1.45 ± 0.51 h, for alone and combined fixed-dose formulation, respectively. Pharmacokinetic parameters were compared by analysis of variance and ratios of AUC0-t, Cmax and 90% confidence intervals obtained. Since confidence intervals exceed the 80% - 125% limits for these parameters, we conclude that there is a significantly pharmacokinetic interaction of lansoprazole when it is administered concomitantly with hyoscine butylbromide.

Effects of melatonin on the oxidative damage and pancreatic antioxidant defenses in ceruleininduced acute pancreatitis in rats

Hepatobiliary & Pancreatic Diseases International 2014年第4期13卷 442-446页

作者： Cristina carrasco Ana Beatriz Rodríguez josé A Pariente Department of Physiology Neuroimmunophysiology and Chrononutrition Research Group University of Extremadura

BACKGROUND： Oxidative stress is recognized as a pivotal effector of several pathogenic processes, including acute pancreatitis. Reactive oxygen species not just cause damage on the main cellular components, but also influence the expression of antioxidant system genes. Antioxidant molecules, such as melatonin, could be good candidates for the treatment of this multidimensional disease. The present study was to evaluate the chemopreventive effect of melatonin in a rat model of ceruleininduced acute ***： Four subcutaneous injections of cerulein（20 μg/kg body weight） were given to Wistar rats at two hours intervals;melatonin was injected intraperitoneally（25 mg/kg body weight）30 minutes before each injection of cerulein. Lipid peroxidation,protein oxidation（carbonyl groups）, total antioxidant status,and glutathione peroxidase activity were determined in pancreatic tissue using commercial ***： The chemopreventive administration of melatonin caused a reduction in lipid peroxidation and protein oxidation due to injections of cerulein. Additionally, melatonin treatment was also able to revert glutathione peroxidase activity and total antioxidant status near to control levels, suggesting that melatonin could prevent from oxidative phenomena in the pancreas, such as lipid peroxidation and protein oxidation,and could stimulate, directly or indirectly, the expression of antioxidant ***： Melatonin, a polyvalent antioxidant, protected the pancreatic damage via the decrease of oxidative stress andincrease of the activities of antioxidant enzymes in ceruleininduced acute pancreatitis.

Proportionally Modular Diophantine Inequalities and Their Multiplicity

Acta Mathematica Sinica,English Series 2010年第11期26卷 2059-2070页

作者： josé carlos ROSALES Manuel Batista BRANCO Paulo VASCO Departamento de lgebra Universidad de Granada Departamento de Matemática Departamento de Matemática Universidade de Trás-os-Montes e Alto Douro

Let I be an interval of positive rational numbers. Then the set S （I） = T ∩ N, where T is the submonoid of （Q0＋, ＋） generated by T, is a numerical semigroup. These numerical semigroups are called proportionally modular and can be characterized as the set of integer solutions of a Diophantine inequality of the form ax rood b 〈 cx. In this paper we are interested in the study of the maximal intervals I subject to the condition that S （I） has a given multiplicity. We also characterize the numerical semigroups associated with these maximal intervals.

Effect of Exogenous Melatonin on Seed Germination and Seedling Growth in Melon(Cucumis melo L.) Under Salt Stress

引用

Horticultural Plant Journal 2019年第2期5卷 79-87页

作者： josé Luis Casta?ares carlos Alberto Bouzo Plant Physiology Laboratory Department of Basic Sciences Universidad Nacional de Luján Laboratory of Research in Physiology and Plant Molecular Biology Facultad de Ciencias Agrarias Universidad Nacional del Litoral

An investigation was carried out to evaluate the effect of different application forms and concentrations of melatonin on germination and initial growth of melon plants in several different salinity conditions. We evaluated germination percentage and growth of seedlings and measured total chlorophyll content, relative electrolyte leakage, peroxidase activity, root viability, proline concentration, relative water content,Na^+/K^+ratio in green parts and K^+leakage from roots. Seed germination percentage under salt stress increased with treatments of 10 and50 μmol·L^(-1) melatonin. Seed treatment and plant watering with melatonin at 50 μmol·L^(-1) improved growth parameters and plants showed higher chlorophyll content as well as better biochemical parameters than non-treated plants. Results suggest that melatonin can alleviate the effect of salt stress during seed germination and first stages of plant development.
