Abstract

An evaluation and preservation solution for human and animal organs, tissues and parts thereof is described, wherein it comprises serum albumin at a concentration of 55-105 g/L, a scavenger and coating compound, preferably dextran compounds and derivatives thereof having essentially the same structure at a concentration of 1-55 g/L weight, and a physiological serum concentration of salts and nutrients in a physiologically acceptable medium.

Claims (15)

1. An evaluation and preservation solution for human and animal organs, tissues and parts thereof, char-acterised in that it comprises serum albumin at a concentration of 55-105 g/L, a scavenger and coating compound, preferably dextran compounds and derivatives thereof having essentially the same structure at a con-centration of 1-55 g/L and a physiological serum concen-tration of salts and nutrients in a physiologically acceptable medium.
2. An evalutaion and preservation solution according to claim 1, wherein the scavenger and coating compound has a molecular weight of from 1 and up to 250 kDa, more preferably from 20 up to 150 kDa, and is most preferably Dextran 40.
3. An evaluation and preservation solution according to any one of the preceding claims, wherein the concen-tration of serum albumin is 65-85 g/L, preferably 75 g/L
and the concentration of the scavenger and coating com-pound is 2-20 g/L, preferably 5 g/L.
4. An evaluation and preservation solution according to claim 1, wherein the salts comprise one or more of so-dium, potassium, calcium, magnesium, phosphate, hydrogen carbonate and chloride ions; and the nutrients comprise one or more of physiologically acceptable carbohydrates, preferably glucose, fatty acids and amino acids.
5. An evaluation and preservation solution according to claim 1, wherein it optionally also contains one or more of the following: a vasodilator, preferably papaver-in; antibiotics; fibrinolytic components, preferably altepas; thrombocyte receptor blockers, preferably abciximab, and hormones, preferably tyroxin/triiodo-tyronin, insulin, cortison, growth hormone or anabolic steroids.
6. An evaluation and preservation solution according to claim 1, wherein it optionally also contains a pure scavenger compound, preferably allopurinol, vitamin E, vitamin C, didox or trimidox; and/or a compound having endothel coating effects.
7. An evaluation and preservation solution according to claim 1, wherein the serum albumin is human or animal serum albumin or recombinant serum albumin produced by genetic engineering.
8. An evaluation and preservation solution according to claim 7, wherein the serum albumin is partially replaced with a hyaluronic acid-based compound having a molecular weight of about 69 kDa.
9. An evaluation and preservation solution according to claim 1, wherein the organs are chosen from lungs, hearts, kidneys, livers, pancreas, small bowels, prefer-ably lungs.
10. A mixed solution ready for use based on a solu-tion according to any one of claims 1-9, wherein it also comprises red blood cells and has an EVF of 15% ~ 3% and wherein the concentration of serum albumin is 50-100 g/L, preferably 60-80 g/L, most preferably 70 g/L of the solution ready for use, and the concentration of the scavenger and coating compounds in the case of dextran compounds is 1-50 g/L, preferably 2-20 g/L, and most preferably 0,5 g/L of the solution ready for use.
11. A method for the evaluation of human and animal organs, tissues and parts thereof for transplantation, comprising the steps of perfusing the organ, tissue or part thereof with the solution according to claim 10, measuring the evaluation parameters, and optionally pre-serving the perfused and accepted organ, tissue or part thereof in said solution until transplantation thereof.
12. Method according to claim 11, wherein a lung is perfused, evaluated and optionally preserved.
13. A method for the transplantation of an organ, tissue or a part thereof from a non-heart-beating human or animal donor, in which the organ, tissue or part thereof is harvested from the donor body, is perfused with the solution according to claim 10, and evaluated, and, if the organ, tissue or part thereof is acceptable for transplantation, it is optionally preserved in said solution until it is transplanted into a donor.
14. Method according to claim 13, wherein the organ, tissue or part thereof is auto-, allo- or xenotransplant-ed.
15. Use of a solution according to claim 1 or 10 for evaluation and preservation of human and animal organs, tissues and parts thereof before transplantation.
