Hepatoprotective effect of prolactin and cysteine contained in perfusion and preservation solutions on porcine liver stored in simple hypothermia.

Introduction: The aim of our study was to determine the results of histidine-tryptophan-ketoglutarate (HTK) solutions modified by the addition of the antioxidant cysteine (Cys), and of prolactin (PRL) on storage of isolated porcine livers.
Methods: We measured in the media of isolated livers stored for 24 hours in HTK (control group) or modified HTK+Cys (0.3 mmol/L)+PRL (3 IU/L study group) the amounts of aspartate aminotransferase (AST), alanine aminotransferase (ALT), lactate dehydrogenase (LDH), lactic acid as well as Ca (II), Mg (II), Na (I) and K (I) ions during a 30-minute perfusion after 24 hours of storage.
Results: All tested markers were released more slowly into HTK+Cys+PRL with less release of K(I) and Mg(II) and greater of Na(I) and Ca(II) ions.
Conclusions: Addition of the Cys and PRL to HTK positively affected 24-hour storage of isolated livers.
