Abstract
Abstract The present invention provides (1) a solution for washing and storing separated organs, characterized by containing, as an effective component, an organogermanium compound represented by the formula (I) <IMAGE> (I) wherein R1 to R3 are each a hydrogen atom, a lower alkyl group such as methyl, ethyl or the like which may be the same or different, or a substituted or unsubstituted phenyl group, and X is a hydroxyl group, an O-lower alkyl group, an amino group or O-Y+(Y is a metal such as sodium, potassium or the like, or a basic group-containing compound such as lysozyme, basic amino acid or the like), and (2) a method for washing and storing separated organs with a solution containing, as an effective component, an organogermanium compound represented by the formula (I).
