Popis: | Background. Non-heart-beating donors (NHBDs) have the potential to reduce the increasing numbers of patients on kidney and liver graft waiting lists. One problem observed with kidneys obtained from NHBDs is the endothelial injury seen on protocol core biopsies after implantation. We postulate that this is caused by a combination of warm ischemia, cold ischemia, and hypertonic citrate during in situ preservation (ISP) rather than hypothermic machine preservation. Our aim was to optimize ISP methods to preserve endothelial structure and function. Methods. An animal model of ISP was used to compare the ability of eight different preservation solutions to protect mammalian vascular tissue exposed to a combination of warm and cold ischemia. Smooth muscle contractile function and endothelial dependent relaxation (nitric oxide production) were determined using an organ bath method. Results. Bretchneider's HTK solution preserved the ability of endothelial tissue to relax vascular tissue in response to acetylcholine (91% relaxation vs. 17% saline control; ANOVA, P |
