The invention relates to the field of organ and tissue perfusion. More particularly, the present invention relates to a method for preparing organs, such as the kidney and liver, for cryopreservation through the introduction of vitrifiable concentrations of cryoprotectant into them. To prepare the organ for cryopreservation, the donor human or animal, is treated in the usual manner and may also be treated with iloprost, or other vasodilators, and/or transforming growth factor &bgr;1. Alternatively, or additionally, the organ which is to be cryopreserved can be administered iloprost, or other vasodilators, and/or transforming growth factor &bgr;1 directly into its artery. The invention also relates to preparing organs for transplantation by a method for the removal of the cryoprotectant therefrom using low (such as raffinose, sucrose, mannitol, etc.), medium (such as agents with intermediate molecular weights of around 600-2,000) and high (such as hydroxyethyl starch) molecular weight agents osmotic buffering agents. The invention is also directed to new post-transplantation treatments such as the use of transforming growth factor &bgr;1, N-acetylcysteine and aurothioglucose.
本发明涉及器官和组织灌注领域。更具体地说,本发明涉及一种通过向器官(如肾脏和肝脏)中导入玻璃化浓度的低温保护剂来准备低温保存器官的方法。为了准备用于低温保存的器官,供体人或动物要按照通常的方式进行处理,也可以用伊洛前列素或其他血管扩张剂和/或转化生长因子&bgr;1进行处理,或者,也可以将伊洛前列素或其他血管扩张剂和/或转化生长因子&bgr;1直接注入要低温保存的器官的动脉。本发明还涉及通过使用低(如棉子糖、蔗糖、甘露醇等)、中(如分子量在 600-2000 左右的中间物质)和高(如羟乙基淀粉)分子量的渗透缓冲剂去除其中的冷冻保护剂的方法制备移植用器官。本发明还涉及新的移植后治疗方法,如使用转化生长因子&bgr;1、N-乙酰半胱氨酸和urothioglucose。
