An artificial solution used as a substitute for blood or extracellular fluid. Also called physiological salt solution. Organs and tissues removed from a living organism can be kept functional for a considerable period of time if they are placed in a substitute solution that is compatible with the animal or perfused with the substitute solution. However, sufficient oxygen must be dissolved in the solution. The substitute solution usually used is one with a composition similar to that of the interstitial fluid of the animal, but a solution with a similar composition is used in mammals, and a slightly lower concentration is used in amphibians.

血液あるいは細胞外液の代用として用いられる人工的な溶液。生理的塩類溶液ともいう。生体から切り出した臓器や組織でも,その動物に適合した代用液の中に入れたり,あるいは代用液で灌流すると,それら摘出標本の機能をかなりの時間維持することができる。ただし,その場合は十分な酸素を溶解させる必要がある。通常用いられる代用液は,その動物の間質液組成に類似した組成の液であるが,哺乳類ではほぼ共通した組成のものが用いられ,両生類にはやや低濃度のものが用いられる。
