Bașak Büyük Tuba Demirci Yasemen Adalı Hüseyin Avni Eroğlu Medicina Wistar rats cold ischemia Amniotic fluid organ preservation renal transplantation Introduction: Kidney-transplantation is a life-saving treatment option for patients with chronic renal failure. Preserving the viability of the organ from the removal of the organ until transplantation into the recipient is one of the most essential factors affecting postransplant success. Kidney tissue is exposed to ischemia following removal of the organ from the donor, initiating some cellular events. Amniotic fluid (AF) was previously reported as a preservation solution for the liver, but not for the kidney yet. The aim of this study is to investigate the effectiveness of AF as a preserving solution for rat kidneys compared with the University of Wisconsin (UW) and Histidine-Tryptophan-Ketoglutarate (HTK), which are reported to be the most commonly used and preferred preserving solutions. Methods: Forty male Wistar albino rats were used in this study in four experimental groups. Group 1: Ringer Lactate (RL, Control) group, Group 2: HTK group, Group 3: UW group, and Group 4: AF group. A midline incision was performed, and the renal artery was isolated under ketamine and xylazine anesthesia. Solutions relevant for groups (cooled to + 4°C) were used for kidney perfusion. Nephrectomy was applied, and the removed kidneys were placed into + 4°C standard organ storage solution and stored at + 4° C for 12 hours. After 12 hours of storage, samples from the kidney tissues were fixed in 10% neutral buffered formalin. Histopathological, immunohistochemistry evaluation and apoptosis detection via TUNEL method were performed. Results: The results of the AF group were close to those of the UW and HTK groups. Tubular necrosis and vacuolization were high in the RL solution group when compared to the other experimental groups. Immunohistochemistry staining for all three markers (TNF-alpha, IL-18, and iNOS) was decreased in the amniotic fluid group, similar to the UW and HTK groups. Also, the number of apoptotic cells was decreased in the AF group compared to control. Conclusions: UW, HTK, and AF had similar and higher protective effects compared to the RL solution. Thus, AF may be used as an inexpensive and readily available alternative natural tissue preservation solution. 2020 artículo científico 0326-3428 https://www.redalyc.org/articulo.oa?id=564262920005 https://www.redalyc.org/journal/5642/564262920005/ https://www.redalyc.org/journal/5642/564262920005/html/ https://www.redalyc.org/journal/5642/564262920005/564262920005.epub https://www.redalyc.org/journal/5642/564262920005/movil en http://www.redalyc.org/revista.oa?id=5642 Revista de nefrología, diálisis y transplante application/pdf Asociación Regional de Diálisis y Trasplantes Renales de Capital Federal y Provincia de Buenos Aires Revista de nefrología, diálisis y transplante (Argentina) Num.1 Vol.40 |
