Abstract: The present invention is concerned with a pharmaceutical delivery device comprising a biologically acceptable silicone polymer matrix having microsealed compartments of 10-200 microns throughout, wherein the microsealed compartments contain a pharmaceutical in a hydrophilic solvent system. The biologically acceptable silicone polymer matrix is formed by in situ cross linking of a liquid, biologically acceptable silicone polymer in an emulsion of pharmaceutical in the hydrophilic solvent system and liquid biologically acceptable silicone polymer. The biologically acceptable silicone polymer matrix is placed in a sealed or unsealed biologically acceptable polymer container.
Abstract: 1-(N-isopropyl-N,N-dimethylamino)-3-(1-naphthoxy)propan-2-ol quaternary salts are useful cardiovascular agents as evidenced by their potent and long-acting anti-arrhythmic, anti-fibrillatory and myocardial ischemia-inhibitory activity. They, furthermore, lack the undesirable side-effects, e.g. .beta.-adrenergic receptor blocking and local anesthetic activity, characteristic of related prior art compounds.

Abstract: The present invention is concerned with the preparation of 3-oxo-pregna-4,17(20)-dien-21-carboxylic acid and esters thereof by the microbial degradation of fucosterol, cholesterol, stigmasterol, campesterol or sitosterol with Mycobacterium sp. NRRL B-8054. The compounds of the present invention are useful antispasmodic agents and are also active against influenza virus.
Abstract: A new method for producing high-strength films, fibers and other shaped articles from chitin has been discovered, whereby an anhydrous solution of chitin is made into the desired shape, the chitin is insolubilized with an organic non-solvent for the chitin and the resultant shaped article, if desired, is oriented, by cold drawing until its properties, such as tensile strength, are substantially enhanced. The films, fibers, and other shaped articles capable of being oriented or in oriented form, are novel and useful in such applications as food wrap and surgical sutures.
