41	Determinação espectrofotométrica do cloridrato de ranitidina em medicamentos / Spectrophotometric determination of ranitidine hydrochloride in medicaments Eliane Maria de Almeida Orsine 07 May 1992 (has links) O cloridrato de ranitidina, um antagonista dos receptores H2 da histamina, foi determinado em comprimidos e injetáveis por espectrofotometria no ultravioleta, a 313nm, e por espectrofotometria no visível, a 615nm, utilizando o cloridrato da hidrazona da 3-metil-2-benzotiazolinona (MBTH) a 0,35% em HCl 0,M e cloreto férrico a 0,40% em HCl 0,1M, como reagentes de cor. Na espectrofotometria no ultravioleta a lei de Beer foi obedecida no intervalo de concentração de 5,0 a 18,0 µg/mL. Quatro amostras comerciais foram analisadas. Os coeficientes de variação foram 0,36% e 0,71% para comprimidos, e 0,51% e 0,24% para injetáveis. A média de recuperação foi 99,88%. Na espectrofotometria no visível a lei de Beer foi obedecida no intervalo de concentração de 1,44 a 5,76 µg/mL. Os coeficientes de variação foram 0,72% e 0,59% para comprimidos, e 0,53% e 0,61% para injetáveis. A média de recuperação foi 99,39%. Os resultados foram comparados estatisticamente e foram compatíveis para as amostras que se encontravam em bom estado de conservação. / Ranitidine hydrochloride, a histamine H2-receptor antagonist, was determined in tablets and injections by ultraviolet spectrophotometry at 313nm , and visible spectrophotometry using as color reagent 0,35% 3-methyl-2-benzothiazolinone hydrochloride in HCl 0,1M and 0,40% ferric chloride in HCl 0,1M. In ultraviolet spectrophotometry, Beer\'s law was obeyed in the range of concentration from 5,0 to 18,0 µg/mL. Four commercially available were analyzed. The coefficients of variation were 0,36% and 0,71% for tablets, and 0,51% and 0,24% for injections. The recovery average was 99,88%. In visible spectrophotometry, Beer\'s law was obeyed in the range of concentration from 1,44 to 5,76 µg/mL. The coefficients of variation were 0,72% and 0,59% for tablets, and 0,53% and 0,61% for injections. The recovery average was 99,39%. The results obtained by using the two methods were statistically compared and were compatible when samples were kept in good conditions of storage.

42	Hollow fiber liquid-phase microextraction in the determination of pharmaceuticals and personal care products Sagristà i Puig, Ester 23 November 2012 (has links) Extensive amounts of pharmaceuticals and personal care products (organic emerging pollutants) are introduced into the environment mainly through wastewater treatment plants discharges either effluent wastewater reaching into the aquatic environment or sewage sludge which is spread onto agricultural land. These compounds are not regulated and their negative effects on humans and wildlife are unknown. One of the main challenges of analytical chemistry is to develop selective and sensitive methods for the detection and quantitation of pharmaceuticals and personal care products and their transformation products in complex matrices. The research presented in the thesis is focused on the development of new methods based on the use of hollow fiber liquid- phase microextraction (HF-LPME) technique and liquid chromatography for the determination of some of the most consume pharmaceuticals and personal care products in wastewaters, environmental waters and sewage sludge. / Tones de substàncies biològicament actives són alliberades contínuament al medi ambient, a través de la descàrrega d’aigües residuals als medis aquàtics o de biosòlids en l’agricultura. La presència d’aquestes substàncies (contaminants emergents) en el medi ambient ha generat una gran preocupació perquè es desconeix com actuen i quins són els mecanismes implicats en la seva transformació i/o transport. Un dels reptes de la química analítica és dissenyar mètodes selectius i sensibles per a la determinació de contaminants emergents en matrius complexes. La recerca presentada en aquesta tesi es centra en el desenvolupament de nous mètodes analítics basats en l’ús de la microextracció enfase líquida amb fibra buida (HF-LPME) i la cromatografia líquida per a la determinació d’alguns fàrmacs i productes d’higiene personal en aigües residuals, medis aquàtics i biosòlids.

43	Recherche de médicaments in silico sur grilles de calcul contre des maladies négligées et émergentes Jacq, N. 12 December 2006 (has links) (PDF) Les grilles de calcul sont une nouvelle Technologie de l'Information permettant la collecte et le partage de l'information, la mise en réseau d'experts et la mobilisation de ressources en routine ou en urgence. Elles ouvrent de nouvelles perspectives de réduction des coûts et d'accélération de la recherche in silico de médicaments contre les maladies négligées et émergentes. Dans ce contexte, la première partie de la thèse a porté sur la conception de services bio-informatiques sur grille. Ils facilitent le déploiement et la mise à jour sur la grille RUGBI de logiciels et de bases de données. La seconde partie a vu le déploiement d'expériences de criblage virtuel à haut débit sur l'infrastructure de grille EGEE. Les expériences ont démontré que les grilles collaboratives ont la capacité à mobiliser d'importantes ressources de calcul dans des buts bien définis pendant une période de temps significative, et qu'elles produisent des résultats biologiques pertinents. grille de calcul recherche de medicaments in silico maladies négligées maladies émergentes services bio-informatiques mise à jour de bases de données criblage virtuel à haut débit
44	Kauno miesto gyventojų savigydos ypatumai esant virškinimo trakto sutrikimams / Self-medication in Gastrointestinal disorders of the citizens of Kaunas city Juodelytė, Elita 08 July 2006 (has links) Final master work, 41 pages, 15 graphical scheme, 6 tables, 29 references and 2 annex. Keywords: Sociological investigation, self-medication, popularity of self-medication, treatment and self-treatment, medicaments, OTC drugs, non-OTC drugs, advertisement, respondent, gastro intestinal disorder, pharmacist in self-medication, herbal remedies. Self-medication should be understood as a treatment of easy and uncomplicated disorder without the help of a health care specialist. Self-medication process occur when the self-healer can exactly realize his or her disorder or symptoms of his or her disease, they can chose the most suitable medicament and use it properly for not longer than 7 days. The proper self-medicament should not cause any undesirable effects and worsen the patient’s health condition. Only OTC drug are suitable in self-medication. Before start using the medicament, the patient should always read carefully the note and information leaflet. Work object: citizen of Kaunas City. Work subject: patients, 2nd year students of the Technological University of Kaunas (KTU), company workers. Work aim: Evaluate the self-healing between the citizen of Kaunas City suffering from Gastrointestinal tract disorder. Task work: 1. Theoretical analysis of self-medication 2.
