    摘要: A ?99Mo/99m¿Tc generator system includes a sorbent column (11) loaded with a composition containing 99Mo. The sorbent column (11) has an effluent end (31) in fluid communication with an anion-exchange column (15) for concentrating 99mTc eluted from the sorbent column (11). A method of preparing a concentrated solution of 99mTc includes the general steps of a) providing a sorbent column (11) loaded with a composition containing 99Mo, the sorbent column having an effluent end (31) in fluid communication with an anion-exchange column (15); b) eluting the sorbent column (11) with a salt solution to elute 99mTc from the sorbent and to trap and concentrate the eluted 99mTc on the anion-exchange column; and c) eluting the concentrated 99mTc from the anion-exchange column with a solution comprising a reductive complexing agent.

    摘要: Described is a novel three-phase pharmaceutical form with constant and controlled release of an amorphous active ingredient stabilized with polymers for a single daily peroral application, which is especially suitable for active ingredients existing in amorphous form or in one or more polymorphous forms, which exhibit poor solubility in crystal form depending on the polymorphous form, particle size and the specific surface area of the active ingredient. The active ingredient can be used in its amorphous or any polymorphous form, which in the process of the preparation of the three-phase pharmaceutical form according to the invention is converted into the amorphous form. The three-phase pharmaceutical form with constant and controlled release of an amorphous active ingredient for a single daily peroral application contains a core consisting of a first and a second phase and a coating representing the third phase. In the first phase the three-phase pharmaceutical form contains an amorphous active ingredient, the water-soluble polymer polyvinylpyrrolidone and a cellulose ether as carriers of the amorphous active ingredient and simultaneously as inhibitors of its crystallization, a surfactant that improves the solubility of the active ingredient and promotes the absorption of the amorphous active ingredient from gastrointestinal tract, in the second phase it contains a cellulose ether and a mixture of mono-, di- and triglycerides as sustained release agents and the third phase is represented by a poorly soluble or gastro-resistant film coating, which in the first few hours after the application controls the release of the active ingredient and can consist of an ester of hydroxypropylmethylcellulose with phthalic anhydride or of a copolymerizate based on methacrylic acid and ethyl acrylate. Described is also a process for the preparation of this pharmaceutical form.

    摘要: An electrolytic cell (10) having an electrolyte (30), a first and second electrode (11, 12) and a primer (20, 40) comprised of lithium polysilicate and carbon, applied to at least one of the first and second electrodes (11, 12), wherein the primer (20, 40) is chemically and electrochemically stable and electronically conductive so as to decrease interfacial resistance in the cell to enhance columbic efficiency.
