PROBLEM TO BE SOLVED: To obtain an organ preserving solution substitutable to hydroxyethyl starch by including hyaluronic acid (salt) and useful for transplantation in which a survival ratio of cells during preserving an organ is kept by improving a defect accompanying to its use. SOLUTION: This organ preserving solution preferably having 6.5-7.8 pH, 240-360 mOsm/kg is obtained by including (A) hyaluronic acid (salt) and (B) other components adjusting osmosis, pH, etc., as necessary. The hyaluronic acid is usable the one obtained from an extract from crista galli, glass body, umbilical cord, etc., or one kind of bacterium, e.g. the one obtained from a cultured material of a hyaluronic acid produced bacterium of genus Streptococcus, and preferably the one obtained from the cultured material of hyaluronic acid produced bacterium is used. As the hyaluronic acid salt, preferably a sodium salt or a potassium salt is used. Preferably, an average molecular weight of the component A is >=10×10<4> , more preferably (10-250)×10<4> . Preferably, a concentration of the component A is 0.05-1.0 wt.%.
