1987年Belzer等研制了一种新的脏器保存液:UW液(University of Wiscon-sin)并用其成功地保存犬胰腺达72小时。此后以UW液替代Collins液已用于临床。为了防止组织水肿,UW液中添加了两种膜非通透性物质乳糖酸(MW358)和糖类棉子糖(MW594),此外还添加了有各种用途的添加剂。添加的别嘌呤醇作为黄嘌呤氧化酶抑制剂可防止生成过氧化物等;腺苷 In 1987, Belzer et al. Developed a new organ preservation solution: UW solution (University of Wiscon-sin) and used it to successfully preserve the canine pancreas for 72 hours. Since then, UW solution instead of Collins solution has been used clinically. In order to prevent tissue edema, two membrane-impermeable substances lactose (MW 358) and sugar raffinose (MW 594) were added to the UW solution. Additives for various uses were also added. Addition of allopurinol as a xanthine oxidase inhibitor prevents the formation of peroxides and the like; adenosine
