An organ to be transplanted, such as a kidney, can effectively be preserved for an increased period of time by perfusion using a perfusate which is made of a Ringer's solution modified by increasing its potassium ion content to 8-20 meq/liter with a stably emulsified perfluorocarbon compound and dissolved albumin. A preferred concentration of the perfluorocarbon compound, for example perfluorodecalin, is 7.5 to 12.5%(W/V) and that of albumin is 1-8%(W/V) based on the perfusate.

An emulsion of perfluorocarbon compounds in an aqueous system has oxygen transporting properties. By incorporation of fat of animal or vegetable origin and at least one of the amino acids glycine, serine or phenylalanine, or urea in the emulsion, the stability of the emulsion will be increased to a point where it can be sterilized by autoclaving, and have nutritive properties as well. The invention also concerns the preparation of an emulsion stabilized in the above manner.
A stable concentrated aqueous emulsion of perfluorochemical, a phospholipid and a triglyceride of fatty acids has been demonstrated which has enhanced stability, diminished particle size and heightened tolerance by biological systems. The emulsion has utility as an oxygen transport medium, such as artificial blood. The emulsion can optionally include addition emulsifiers of SURFYNOL®SE surfactant and PLURONIC® P-105 surfactant. The emulsion is produced using an improved emulsification technique.

Coatings are cured by simultaneous exposure to radiant energy and condensing inert perfluorochemical vapors. The invention also includes an apparatus for use in curing coatings having a vessel (10) with reservoir (5) filled with inert perfluorochemical liquid (4), heated by heater (2). Cooling coils (13) and (14), for condensing perfluorochemical vapors (6), are located in the inlet (11) and outlet (12) of the vessel (10). A coating (8) on a substrate (7) is carried through the vessel (10) on a continuously moving belt (15). The coating (8) is cured by vapors (6) and radiant energy from energy source (9) passing through windows (16).
