Abstract: A disposable specific gravity tester of liquids such as urine comprising a form-maintaining, flexible or resilient, transparent plastic pipet-type tube, one end of which is integrally closed to form a self-contained bulb, the other normally open end of which is fixedly closed with a solid liquid-permeable plug permitting inward passage there through of the liquid to be tested, and at least one floatable solid testing body in the tube with a predetermined specific gravity at or approximating the expected or normal specific gravity of the liquid; and its method of use, comprising squeezing the bulb while the other plugged end is below the surface of the liquid, releasing the squeezing force to suck up into the tube sufficient liquid to float the testing body or bodies, and observing if and/or which body or bodies sink, float or remain suspended in the liquid.

Abstract: A novel crystalline monohydrate of 7-[D-.alpha.-amino-.alpha.-(p-hydroxyphenyl)acetamido]-3-methyl-3-cephem-4 -carboxylic acid is prepared and found to be a stable useful form of the cephalosporin antibiotic especially advantageous for pharmaceutical formulations.

Abstract: This invention concerns novel water-soluble compositions of the antitumor agent 4'-(9-acridinylamino)methanesulfon-m-anisidide (m-AMSA). More particularly, water-soluble compositions are provided which comprise a mixture of m-AMSA with lactic acid. The compositions enable m-AMSA to be administered as an aqueous solution without the necessity of using dimethylacetamide as a pharmaceutical vehicle.

Abstract: The invention concerns a crystalline monogluconate salt of the antitumor agent 4'-(9-acridinylamino)-methanesulfon-m-anisidide and compositions comprising mixtures of such salt with an organic acid selected from gluconic acid, gluconolactone or mixtures thereof. The novel salt and compositions are characterized in having unexpectedly high water-solubility.

Abstract: A novel crystalline monohydrate of 7-[D-.alpha.-amino-.alpha.-(p-hydroxyphenyl)acetamido]-3-methyl-3-cephem-4 -carboxylic acid is prepared and found to be a stable useful form of the cephalosporin antibiotic especially advantageous for pharmaceutical formulations.
