Abstract

The invention relates to isolated organ protection liquid. The protection liquid takes water as a solvent and is prepared from the following components with the mass concentration or the mol concentration: a cell swelling inhibitor with the concentration of 0.8 to 1.6g/L, a cell membrane stabilizing agent with the concentration of 0.01 to 0.015g/L, adenosine with the concentration of 0.005 to 0.008mol/L, allopurinol with the concentration of 0.001 to 0.002mol/L, glutathione with the concentration of 0.001 to 0.005mol/L, an H<+> buffering agent with the concentration of 0.1 to 0.12mol/L and magnesium sulfate with the concentration of 0.003 to 0.006mol/L, wherein the cell swelling inhibitor is prepared from polyvinyl alcohol, potassium hydroxide and sodium hydroxide. Compared with the priorart, the solution viscosity is reduced, a cell membrane is protected and the production cost is reduced.

Description

Technical field [0001] The invention relates to organ transplantation technology, in particular to an isolated organ protective liquid. Background technique [0002] The organ preservation solution is of great significance for improving the utilization rate of organs and thus the success rate of transplantation operations. Belzer et al. believe that the protective solution must meet the following six points if it wants to successfully preserve isolated organs: 1. Reduce cell edema caused by cryopreservation; 2. Prevent acidification of cells; 3. Prevent cell gap expansion during lavage storage 4. Prevent or reduce reperfusion injury; 5. Provide substrates for regeneration and high-energy phosphorylation synthesis; 6. Keep the intracellular environment stable. [0003] At present, the most used organ preservation liquid in hospitals is UW liquid, designed by Belter, and it has been confirmed that the liver, kidney and other isolated organs preserved with it have good clinical appli...
