Introduction: Biolasol is a solution developed in Poland for flushing the kidneys, liver, heart and pancreas by simple hypothermia method prior to transplantation. The solution supports the cellular integrity of grafts during ischemia-reperfusion injury (IRI).The aim of the study was to evaluate the impact of the concentration of prolactin added to Biolasol on selected biochemical parameters of kidney injury.Materials and methods: Biolasol was modified by the addition of prolactin at 1 μg/L, 10 μg/L and 100 μg/L and by ascorbicacid at 0.5 mmol/L. After 2 h and 48 h of storage, the levels of alanine aminotransferase, aspartate aminotransferase, lactate dehydrogenase enzymes, sodium and potassium concentrations, pH and osmolarity parameters were assessed in the perfusates.Results: The addition of prolactin to Biolasol significantly improves the biochemical parameters of grafts in the models of rinsing, perfusion and reperfusion of isolated porcine kidneys.Conclusions: The study indicates the nephroprotective role of Biolasol with the addition of vitamin C and prolactin at a 100 μg/L.

“…A number of our studies indicate the hepatoprotective and nephroprotective effects of prolactin [ 8 , 20 , 21 ]. PRL protects the structure and function of cells against the negative effects of ischemia and hypoxia [ 20 , 37 ].…”

“…They have shown that the used solutions protect the kidneys from ischemia-reperfusion injury in a similar way [ 3 ]. Based on our histopathological examinations, we have found that adding prolactin to the HTK preservation fluid minimizes hepatocyte damage in the model using an isolated rabbit liver [ 8 ]. Cierpka et al confirmed by means of histopathological examination that the structure of the isolated porcine kidney cortex was not damaged after using Biolasol [ 1 ].…”

Biolasol is a newly developed solution for storing the liver, pancreas, kidneys, and heart by simple hypothermia. It exhibits high efficacy in maintaining structural and functional integrity of the graft prior to its transplantation. The solution was modified by the addition of ascorbic acid (0.088g/l) and ascorbic acid with prolactin (1 μg/l PRL + 0.088g/l vitamin C). The effectiveness of the obtained solutions in the protection of nephrons of isolated porcine kidneys was assessed based on the analysis of the activity of ALT (alanine aminotransferase), AST (aspartate aminotransferase), and LDH (lactate dehydrogenase) as well as lactate concentration determined in perfundates collected after 2 h (0′ and 30′ preservation) and 48 h (0′ and 30′ preservation) of graft storage. It has been found that the synergistic action of Biolasol components determines the integrity and stability of cell membranes, which in turn affects the proper functioning of the organ after transplantation. The addition of ascorbic acid and prolactin to Biolasol affects the maintenance of the normal cytoskeleton of the stored graft.

“…Prolactin at a dose of 100 IU/L was added to HTK (control test: HTK without prolactin), and the degree of hepatocyte damage was analysed based on the measurement of biochemical parameters (ALT, AST, LDH, GGTP, and lactates) and the histopathological examination of tissues. It was found that, in the livers rinsed with HTK with the addition of PRL, the outflow of enzymes was significantly lower compared to the control group, which suggests that prolactin inhibits the process of liver cell cytolysis [7]. Budziński et al evaluated the effect of prolactin added to HTK on the degree of hepatocyte apoptosis in an isolated porcine liver model.…”

Pharmacological Benefits and Risk of Using Hormones in Organ Perfusion and Preservation Solutions in the Aspect of Minimizing Hepatic Ischemia-Reperfusion Injury during Storage

BioMed Research International

2019

For several years, research has been carried out on the effectiveness of solutions for perfusion and preservation of organs, including the liver. There is a search for an optimal pharmacological composition of these solutions, allowing to preserve or improve vital functions of the organ for as long as possible until it is transplanted into a recipient. Hormones due to their properties, often resulting from their pleiotropic effects, may be a valuable component for optimizing the composition of liver perfusion and preservation solutions. The paper presents the current state of knowledge on liver perfusion and preservation solutions modified with hormones. It also shows the characteristics of the hormones evaluated, taking into account their physiological functions in the body.
