Abstract: Non-ionic, lipophilic substances are isolated from aqueous or aqueous-organic solution by treatment with a macroreticular polymeric absorbent followed by elution with additional or a different organic solvent.
Abstract: A unit dose applicator for liquid ophthalmic medicaments in solution or suspension has an elongated housing for the medicament; at one end of the housing there is an opening for at least partially emptying the contents of the housing; at the other end of the housing is a second opening; and the second opening is capped by a diaphragm-like seal having a sufficient displacement potential to exude only 1 to 4 drops of the medicament.
Abstract: The invention relates to the treatment of gray matter edema in the brain or spinal chord by the administration of benzofuranyloxyacetic acids, indeno[5,4-b]furancarboxylic acids, their analogs and salts thereof.
Abstract: Combinations of thiopeptin or one of its analogs with a pyromellitic diimide are shown to synergistically increase the feed efficiency of economically important ruminant animals, especially cattle, sheep, and goats.
Abstract: There is disclosed a macrolide isolated from the fermentation broth of a microorganism identified as MA-5285 which morphological analysis reveals to be a strain of Streptomyces hygroscopicus. The compound's structure is presented based upon analytical studies. The compound has insecticidal and antiparasitic activity.

Abstract: 1-(Substituted-aminoalkoxyphenyl)-2-methylene-1-alkanones, a class of compounds possessing anti-allergic properties for use in the treatment of allergic conditions, such as asthma prepared by etherifying an alkanoylphenol with an aminoalkyl halide, converting the ether formed to a salt of Mannich base by reacting it with a salt of a secondary amine in the presence of formaldehyde or paraformaldehyde and treating the Mannich salt with a weak base to deaminate the same and form the final product.
Abstract: Ivermectin, an antiparasitic agent which is insoluble and unstable in water, is solubilized by the formation of colloidal particles, called micelles, with surface active agents as solubilizers and stabilized by using cosolvents and/or appropriate substrates in the aqueous formulation. The liquid formulations are suitable for use as parenteral or oral administration for the treatment of parasitic infections.
Abstract: The invention relates to the treatment of gray matter edema in the brain or spinal chord by the administration of (indanyloxy)acetic acids, and analogs and salts thereof.

Abstract: A pump is provided with an adjustable tapered seal mechanism so that when wear occurs a simple adjustment is required rather than a dismantling of the pump and replacement with a new seal.
Abstract: Substances isolated after cultivation of a microorganism belonging to the genus Aspergillus in a culture medium include a compound with structural formula: ##STR1## Together with the corresponding free acid of the above ester, its salts and lactone, compound I is a member of a class of hypocholesterolemic and hypolipemic medicaments.
Abstract: 6-Hydroxy-2-benzothiazolesulfonamide is useful for the topical treatment of elevated intraocular pressure. Ophthalmic compositions including drops and inserts are disclosed.

Abstract: Cell-specific ligands comprising conjugates of saccharides and amino acids or peptides are synthesized from amino acids such as ornithine, lysine, peptides such as dilysine, diornithine or oligolysine and selected saccharides having reactive functional groups protected by appropriate blocking groups. Such glycopeptides are useful as tissue specific substances, which when coupled with bioactive materials through metabolizable or hydrolyzable linkages, deliver such bioactive materials to the selected site. In this manner, antiinflammatory drugs such as dexamethasone are linked through a metabolizable or hydrolyzable linkage and on administration to an animal suffering from inflammatory disease carries the drug to the site of inflammation for intracellular release. Other examples include the macrophage ligand N.sup.2 -N.sup.2, N.sup.6 -Bis-[3-(.alpha.-D-mannopyranosylthio)propionyl]-6-lysyl-N.sup.6 -[3-(.alpha.-D-mannopyranosylthio)propionyl]-L-lysine, 5, which when coupled to .beta.
