Abstract: Glucose contained in urine is determined by contacting a sample with a diagnostic composition comprising an absorbent carrier impregnated with glucose oxidase, peroxidase, an indicator compound such as o-tolidine, and as a buffer, 2-(N-morpholino)-ethane-sulfonic acid.

Abstract: Pharmaceutical compositions comprisingA. at least one member of the group consiting of 5-(4-chloro-5-sulfamoyl-2-thenylaminophenyl)-tetrazole and the pharmacologically compatible salts thereofB. at least one member of the group consisting of 3-(3-oxo-17.beta.-hydroxy-4,6-androstadien-17.alpha.-yl)-propionic acid-.gamma.-lactone and the pharmacologically compatible salts of 3-(3-oxo-17.beta.-hydoxy-4,6-androstadien-17.alpha.-yl)-propionic acid, and a pharmaceutical carrier;Possess outstanding activity for treating hydropic conditions and prevent undesirable increased excretion of potassium without at the same time impairing the desired excretion of water and sodium.

Abstract: Nitrofuryl-triazolo[4,3-b]pyridazine compounds of the formula ##SPC1##WhereinR.sub.1 is lower alkoxy radical or a saturated 5- or 6-membered heterocyclic ring attached via a cyclic nitrogen atom, which heterocyclic ring can also contain, in addition to said cyclic nitrogen atom, a cyclic oxygen atom or an optionally lower alkylated cyclic nitrogen atom and R.sub.2 is a hydrogen atom or R.sub.1 and R.sub.2 together represent an additional valency bond,Are outstandingly effective as bacteriostats and are particularly useful in the treatment of bacterial infections in the urinary tract.

Abstract: Certain novel nitrofuran compounds of the formula: ##SPC1##WhereinHet is an aromatic heterocylic linkage;B is a bond or vinylene;Y is O or S;m is 0 or 1;X is hydrogen, lower alkyl or alkanoyl; andThe R's are variously defined;Are outstandingly effective bacteriostats and bactericides.

Abstract: NADP-dependent dehydrogenases are separated and purified by subjecting mixtures containing it to affinity chromatography using as the affinity chromatography material a nucleotide with a phosphate group in the 2'- or 3'-position, bound to a solid carrier.

Abstract: New nitroimidazolyl-triazolo-pyridazines of the formula: ##SPC1##WhereinZ is methyl or amino which can be substituted by lower alkyl,And the pharmacologically compatible acid-addition salts thereof, exhibit outstanding anti-microbial activity against bacteria and protozoa, and also systemic effectiveness.

Abstract: The new enzyme steroid-.DELTA.-isomerase is provided, as well as a process for producing same, comprising digesting a micro-organism containing said isomerase, extracting same by destruction of the cell wall with a buffer solution containing a non-ionic surfactant, centrifuging the resulting mass and discarding the precipitate, applying the extract to an anion exchanger, eluting the enzyme with a buffer solution containing a non-ionic surfactant, heating the eluate, separating the precipitate and isolating the enzyme therefrom from the supernatant.

Abstract: Coated tablets are prepared by applying to a core of active material, at least one layer of a coating composition made up of a film forming aqueous synthetic resin dispersion and from 2-50% by weight of a water or alkaline soluble material and thereafter permitting the coating composition layer to dry. The resulting coated tablet has a core surrounded by a continuous porous matrix of synthetic resin formed from the aqueous dispersion which is insoluble in water and insoluble in the gastrointestinal tract. The pores of the continuous resin matrix are filled with a discontinuous particulate material which is water or alkaline soluble. The coated tablet initially is air and moisture tight.

Abstract: Glucose is converted into gluconic acid by oxidation with oxygen in aqueous solution, by a process comprising passing a glucose containing aqueous solution over a catalyst which contains glucose oxidase and catalase, bound to an appropriate carrier, in immediate proximity to one another. The process avoids the disadvantage of previous catalytic processes depending on catalysts which rapidly lose their activity and is adapted to large-scale operation.

Abstract: New 3,4-dihydro-2H-naphthalene-1-one-5-oxypropyl-piperazine derivatives of the formula: ##SPC1##WhereinA is hydrogen or hydroxyl;X is hydrogen, halogen, alkyl orAlkoxy; andn is 0, 1 or 2;And the pharmacologically compatible salts thereof; are outstandingly effective in blood pressure depressing and tranquilizing or sedative therapy; further, these compounds have antioedematous action and reduce capillary permeability.
