Effect of sugars in the preservation solution on liver storage in rats.
We have performed 128 rat liver transplants in order to examine the effect of sugars in preservation solutions on cold storage of rat livers. Glucose (Mw. 180), sucrose (Mw. 348), and raffinose (Mw. 594) were tested. Rat livers were preserved at 4 degrees C for 12, 16, 18, and 24 h in standard Eurocollins solution (EC solution) (solution A) or in one of three modified EC solutions in which 194 mM/liter glucose in standard EC solution was replaced by 140 mM/liter of glucose (solution B), sucrose (solution C), or raffinose (solution D). The osmolarity of the modified solutions (solution B-D) was 320 mOsm/liter. Using standard EC solution (solution A), the 1-week survival rate of rats receiving livers preserved for 12, 16, 18, or 24 h was 6/8, 4/8, 1/8, and 0/4, respectively. With solution B, in which 194 mM/liter glucose was replaced by 140 mM/liter glucose, 1 week survivors following transplantation of livers preserved for 12, 16, 18 or 24 h were 4/8, 3/8, 2/8 and 0/4, respectively. Solution C, which was identical to solution A except for the replacement of 194 mM/liter glucose by 140 mM/liter sucrose, gave the following 1-week survival rates: 5/8 for 12 h, 5/8 for 16 h, 2/8 for 18 h, and 0/4 for 24 hours preservation, respectively. Using solution D, which differed from A in the replacement of glucose by 140 mM/liter raffinose, the 1-week survival rates of rats grafted with livers preserved for 12, 16, 18, and 24 h were 6/8, 5/8, 3/8 and 0/4, respectively.(ABSTRACT TRUNCATED AT 250 WORDS)
