Abstract: Lipid microemulsions which can be added to cell culture media to provide essential lipids in a bioavailable form and their components are disclosed. Methods to disperse lipids in culture media by the use of one or more emulsifiers are described. Further disclosed are media which support growth of cells and production of recombinant, viral and/or native products wherein lipids are supplied in the form of microemulsion.

Abstract: Peptide medicaments, and antibody thereto, useful for treating or preventing diseases, particularly diseases involving an inflammatory response by a host organism against infection, that are preferably derived from the .beta. subunit, CD18, of the leukocyte integrins, and that have the property of either interfering with, or preventing undesirable leukocyte adhesion to biological materials, particular to endothelial cells, or that interfere with, or prevent the chemotaxis of leukocytes through the endothelial cell monolayer, consequently minimizing undesirable cell/tissue leukocyte binding and thus preventing or minimizing diseases resulting therefrom.
