Abstract

Background/aims: During cold preservation of liver grafts, expression of tissue adhesion molecules has been reported as a factor indicative of preservation injury. Some biochemical agents as well as increased levels of intracellular calcium also play important roles in preservation injury during cold storage. In the current study, we aimed to test if the addition of a calcium channel blocker, sodium nitroprusside, or glutathione into preservation solution would reduce upregulation of adhesion molecules, thus leading to decreased preservation injury in the rat liver. Methods: Fifty Albino Wistar rats, weighing 200±50 g, were divided into 1 control (perfused with Wisconsin solution, without preservation) and 4 study groups of rat livers (10 livers each). Livers in study groups were harvested, perfused, and preserved for 16 hours in 4 different solutions (Wisconsin solution alone, Wisconsin solution+verapamil, Wisconsin solution+ sodium nitroprusside and Wisconsin solution+glutathione). At the end of the preservation time, levels of graft tissue adhesion molecule (ICAM-1) expression were analyzed. Results: Preservation for 16 hours with Wisconsin solution alone and Wisconsin solution+verapamil perfusates caused significantly more ICAM-1 expression than did preservation for 16 hours with Wisconsin solution+sodium nitroprusside and Wisconsin solution+ glutathione perfusates (p=0.010). No significant difference was found in ICAM-1 expression between the Wisconsin solution+ sodium nitroprusside and Wisconsin solution+glutathione groups. In the control group, perfusion with Wisconsin solution alone, without preservation, represented minimal ICAM-1 expression, reflecting minimum preservation injury (p=0.0003). Conclusions: Addition of sodium nitroprusside and glutathione into the Wisconsin solution decreased levels of ICAM-1 molecule expression, which reflects lower levels of preservation injury. In this study, the addition of verapamil to the perfusate/preservation solution for reducing the intracellular calcium accumulation had no effect on tissue ICAM-1 molecule expression.

Özet

Amaç: Karaciğer greftlerinin soğuk saklama sürelerinde, adezyon molekül ekspresyonları ve intra selüler kalsiyum birikmesi gibi faktörlerin, preservasyon hasarının bir göstergesi olabileceği önceki çalışmalarda gösterilmiştir. Bu çalışmada, kalsiyum kanal blokörü, sodyum nitroprusside ve glutatyon gibi ajanları n saklama solüsyonlarına eklenmesinin, rat karaciğerlerinde, adezyon molekül ekspresyon miktarında bir azalmaya yol açıp açmayacağı araştırıldı. Metot: Ağırlıkları 200±50 g olan elli adet Wistar rat birisi kontrol (sadece perfüzyon) dördü çalışma gurubu olmak üzere, on'ar rat'dan oluşan beş guruba ayrıldı. Greftlerin çıkartılmasını takiben, çalışma gurupları, 4 ayrı solüsyonda (yalnızca Wisconsin solüsyonu, Wisconsin solüsyonu+ Verapamil, Wisconsin solüsyonu+Sodyum Nitroprusside ve Wisconsin solüsyonu+Glutatyon) 16 saat soğuk preservasyona alındı. Daha sonra karaciğer greftlerinin ICAM-1 molekül ekpresyonları analiz edildi. Sonuçlar: Yalnızca Wisconsin solüsyonu ve Wisconsin solüsyonu+Verapamil ile preservasyon yapılan guruplarda; Wisconsin solüsyonu+Sodyum Nitroprusside ve Wisconsin Solüsyonu+Glutatyon guruplarına göre anlamlı ölçüde fazla ICAM-1 ekpresyonu tespit edildi (p=0.010). Wisconsin solüsyonu+Sodyum Nitroprusside ve Wisconsin Solüsyonu+ Glutatyon gurupları arasında ICAM-1 ekpresyonu bakımından bir fark gözlenmedi. Yalnızca Wisconsin solüsyonu ile preserve edilip, soğuk iskemiye tabi tutulmayan kontrol gurubunda, minimal preservasyon hasarının bir göstergesi olarak, en az ICAM-1 ekspresyonu tespit edildi (p=0.0003). Tartışma: Wisconsin solüsyonuna, Sodyom Nitroprusside ve Glutatyon gibi ajanların eklenmesi, rat karaciğerlerinde, preservasyon hasarı nın azaltılmasına yardımcı olabilir. Greft dokusundaki intraselüler kalsiyum akümülasyonunun azaltılması amacı ile preservasyon solüsyonuna eklenen Verapamil, doku ICAM-1 ekpresyonunda bir azalmaya yol açmamıştır.
