Background: The most important factor affecting the success rate of liver transplants is the preservation of the normal histologic and biochemical properties of the cells in the tissue taken. The study aimed to identify the possible increase in efficacy of ethyl pyruvate, which has a hepatoprotective effect, on the University of Wisconsin (UW) solution. Methods: Rats were randomly selected and divided into 4 groups. After a laparotomy, the small intestines were removed from the abdomen and the portal pedicle was identified. Arterial and venous circulation of the liver was interrupted. After the portal vein was cannulated (and the distal of the portal pedicle was ligated, the liver was perfused with a solution. Perfusion solution was selected as Ringer Lactate in Group 1. In group 2, UW solution was chosen as the perfusion solution. In Group 3, the perfusion solution was chosen as the UW solution, but ethyl pyruvate at a dose of 40 mg/kg was administered intraperitoneally to the experimental animals 30 minutes before hepatectomy. In Group 4, as a perfusion solution, a UW solution with 40 mg/kg dose of ethyl pyruvate added to it was used. Results: With TUNEL and Caspase-3 staining, a significant decrease was found in the apoptosis rates of Groups 2, 3, and 4 at the 12th hour post hepatectomy when compared with Group 1. When the morphometric liver sinusoid/parenchyma ratios and vena centralis diameters of the groups were examined, it was found that all preservation solutions containing the UW solution were more protective than the RL solution. Conclusions: Ethyl pyruvate is regarded as a promising agent that can increase the effect of the UW solution on organ preservation solutions. Because this study is the first in literature to apply ethyl pyruvate in preservation solutions, additional studies with larger series and different doses are needed.
