Albumin particles in the nanometer and micrometer size range in an aqueous suspension are rendered stable against resolubilization without the aid of a cross-linking agent and witout denaturation, by the incorporation of a stabilizing agent in the particle composition. Stabilizing agents disclosed include reducing agents, oxdizing agents, hydrogen-accepting molecules, high molecular weight polymers, and sulfur-containing ring compounds. Also disclosed are fibrinogen-coated particles, cross-linked or non-cross-linked, and their use as co-aggregants with platelets and with themselves for purposes of shortening bleeding time and enhancing the effect of thrombin.

A composition comprising a biologically active agent and a permeation enhancing lipid wherein the permeation enhancing lipid is a platelet activating factor antagonist or a biologically inactive a platelet activating factor, and increases permeability of the biologically active agent across a tissue layer. Also disclosed is a process of increasing the permeability of a biological agent across a layer tissue comprising contacting the tissue layer with a composition comprising the biological agent and a permeation enhancing lipid wherein the permeation enhancing lipid is a platelet activating factor antagonist or a biologically inactive platelet activating factor.
