    摘要: A method of testing a substance potentially active in the field of lipolysis comprising: preparing a substrate containing at least one triacylglycerol; placing this substrate in contact with a substance potentially active in the field of lipolysis, and with a lipoprotein lipase, in the presence of a cofactor of lipoprotein lipase, for a period of time sufficient to release at least in part one fatty acid of the triacylglycerol; and determining the capacity of inhibition of the release of the fatty acid resulting from the activity of the lipoprotein lipase, under the action of said potentially active substance, and evaluating the result of the inhibition which is either compared to the result obtained in the absence of the potentially active substance tested or compared with the result obtained in the presence of a known inhibitor acting as reference. Cosmetic and pharmaceutical uses are described.

    摘要: A collagen-based composition including microcapsules of atelocollagen or of a mixture of atelocollagen and a polysaccharide, particularly glycosaminoglycan, suspended in a viscous biocompatible carrier solution. Together, the microcapsules and the viscous carrier solution preferably have a viscosity such that the composition may be injected, in particular as a continuous thread from a needle. Said composition is readily injectable and may be used as a soft or bony tissues filling material for, or as a system for the controlled delivery and release of biologically, cosmetically or pharmaceutically active substances.

    摘要: The invention relates to novel amphiphilic complexes, a method for their preparation, and the compositions containing them. Said amphiphilic complexes result from the reaction, at a temperature between ambient temperature and 80null C., between a protein or polypeptide whose average molecular mass is greater than or equal to 5,000 Daltons and a fatty chain whose carbon atom number is between 4 and 30 selected from fatty acid, fatty alcohol, fatty amine, with the exclusion of undecylenic acid ; the protein or polypeptide/fatty chain weight ratio ranging from 1000/1 to 1/10.
