Abstract: A peptide of the formulaR-SER-LEU-PRO-SER-PRO-SER-ARG-LEU-PRO-GLY-PRO-SER-ASP-THR-PRO-ILE-LEU-PRO-G LN-OHwhereinR: H or R.sub.1 -Ser-Ser-Ser-Ser-Lys-Ala-Pro-Pro-Pro group,R.sub.1 : H or R.sub.2 -R.sub.3 -Asp-Asp-Pro-Arg-Phe-Gln-Asp group,R.sub.2 : H or R.sub.4 -Asp-His-Pro-Leu-Thr group,R.sub.4 : H-R.sub.5 -Gly-Gly-Pro-Lys group,R.sub.5 : Cys or Tyr group, andR.sub.3 : Cys or S-acetamidemethyl-Cys group,or salt thereof, has utility for the preparation of antibodies for assaying human chorionic gonadotropin or as a labelling reagent.

Abstract: The invention relates to a group of novel N,N'-di-substituted amines, especially adapted for use as antitussive agent.These compounds can be expressed by the following general formula: ##SPC1##WhereinR.sub.1 stands for a member selected from the group consisting of hydrogen, methyl and methoxy;R.sub.2 stands for a member selected from the group consisting of phenyl, tolyl, xylyl, ethylphenyl, o- and m-methoxyphenyl, trimethylphenyl and .alpha. -naphthyl.

Abstract: Encapsulated medicaments are prepared by dissolving a wall material for capsules in at least one organic solvent poorly miscible with water which has a boiling point of less than 100.degree.C., a vapor pressure higher than that of water and a dielectric constant of less than about 10, dissolving or dispersing in the resulting solution a medicament which is insoluble or slightly soluble in water, dispersing the resulting solution or dispersion to the form of fine drops in a liquid vehicle comprising an aqueous solution of a hydrophilic colloid or surface active agent, and then removing the organic solvent by evaporation.

Abstract: Microcapsules are made by (a.) dispersing or dissolving a core substance in a film-forming polymer solution, (b.) emulsifying in fine droplets the resulting dispersion or solution in a vehicle which is poorly miscible with the solvent of the polymer solution and which doesn't dissolve said polymer to prepare an emulsion, and (c.) adding to the emulsion a non-solvent for the polymer wherein the non-solvent is miscible with the solvent, poorly miscible with the vehicle, and does not dissolve the polymer, whereby the solvent is removed by being absorbed by non-solvent emulsion droplets to precipitate the polymer film around the core substance.

Abstract: A peptide of the formulaR--Lys--Lys--Glu--Asp--Asn--Val--Leu--Val--Glu--Ser--His--Glu--Lys--Ser--Le u--Gly--Glu--Ala--Asp--Lys--Ala--Asp--Val--Asp--Val--Leu--Thr--Lys--Ala--Ly s--Ser--Gln--OHwherein R is H, H--Tyr-- or R.sub.1 --Pro--Arg--, R.sub.1 is H, H--Tyr-- or R.sub.2 --Ala--Gly--Ser--Gln--Arg--, and R.sub.2 is H, H--Cys-- or H--Tyr--, or a salt thereof, is useful for assaying human parathyroid hormone (h-PTH).
