PHARMACOLOGICAL STUDIES ON NOVEL BASIC AMINOALKYL ARYL ETHERS AS POTENTIAL LOCAL ANAESTHETICS
Following our previous investigations on certain new aminoalkyl aryl ethers, which showed promising and outstanding local anaesthetic properties, the local anaesthetic activity and duration of action of a further selection of four novel derivatives of the above-mentioned series, used as hydrochloride salts, have been determined by the ill vivo rat sciatic nerve test. These are: N,N-dimethyl...
متن کاملPlatelet adhesion studies on dipyridamole coated polyurethane surfaces.
Surface modification of polyurethanes (PUs) by covalent attachment of dipyridamole (Persantin) is known to reduce adherence of blood platelets upon exposure to human platelet rich plasma (PRP). This effect was investigated in further detail. First platelet adhesion under static conditions was studied with four different biomaterial surfaces: untreated PU, PU immobilised with conjugate molecule ...
متن کاملStudies on Indium Sorption from Iodide Medium by Polyurethane Foam
A sorção de iodeto de índio em espuma de poliuretano do tipo poliéter (EPU) foi investigada. O sistema apresentou rápida cinética e máxima sorção numa faixa significativa de meio ácido ou básico e razões de distribuição acima de 10 L kg ([KI] 0.6 mol kg). A análise do equilíbrio de sorção indicou o tetraiodo-indato (MInI 4 )como a principal espécie sorvida na matriz da espuma. A isoterma de Lan...
متن کاملStudies on Oxygenated Fuel Additives: Ethers and Acetals
Ever increasing political pressure for a cleaner environment has triggered large research efforts over the past decade within the automobile and solvent industries to develop new, oxygenated, low atmospheric reactivity fuels and solvents, respectively. The main stimulus for the interest in such compounds in Europe is existing or pending legislation demanding the regulation of the reactivity of ...
متن کاملTOXICOLOGICAL STUDIES ON CERTAIN AMINOALKYL ETHERS AS POTENTIAL LONG-ACTING LOCAL ANAESTHETICS
The acute intravenous toxicities of a selection of three potential long-acting local anaesthetics belonging to the series of2- phenoxyethyldialkylamine were determined in mice. Two of the compounds were tertiary amines and the third a quaternary ammonium derivative.The I.V. median lethal dose, (LDso) of one of the tertiary compounds, 21A [N, N- diethyl-2- (2,6- diisopropyl) ethyl amine hyd...
