CALCIUM-ANTAGONISTS IN SODIUM LACTOBIONATE SUCROSE SOLUTION FOR RAT-LIVER PRESERVATION
CALCIUM-ANTAGONISTS IN SODIUM LACTOBIONATE SUCROSE SOLUTION FOR RAT-LIVER PRESERVATION TRANSPLANTATION Tokunaga, Y., Collins, G. M., Esquivel, C. O., Wicomb, W. N. 1992; 53 (4): 726-730Abstract
The effects of the calcium antagonists, chlorpromazine (CPZ), nisoldipine (NIS), trifluoperazine (TFP), and nicardipine (NIC) were compared in rat livers following either 20- or 30-hr ice storage in sodium lactobionate sucrose solution (SLS). Survivals beyond 7 days after orthotopic liver transplantation following 20-hr cold storage were 1/14 in the University of Wisconsin solution, 4/14 in SLS, 4/8 in UW+CPZ, 7/8 in SLS+CPZ. Survivals beyond 7 days after OLT following 30-hr cold storage were 3/8 in SLS+CPZ, 3/8 in SLS+NIS, 2/8 in SLS+TFP, 0/8 in SLS+NIC, and 0/8 in SLS alone. Survival rates were significantly (P less than 0.05) better in both SLS+CPZ and SLS+NIS than in UW and SLS alone. The effluent lactate dehydrogenase (LDH) levels and pH changes were measured at the time of OLT. After 20 hr, LDH levels were 525 +/- 78 IU/L (mean +/- SEM) in UW, 492 +/- 44 in SLS, 322 +/- 35 in UW+CPZ, and 290 +/- 39 in SLS+CPZ. After 30 hr, LDH values were 416 +/- 40 in SLS+CPZ, 450 +/- 25 in SLS+NIS, 448 +/- 21 in SLS+TFP, 573 +/- 18 in SLS+NIC, and 614 +/- 68 in SLS. The LDH levels for SLS+CPZ and SLS+NIS were significantly lower than those of SLS and UW (P less than 0.01). The pH changes in the effluent were significantly less in both the CPZ and NIS groups (P less than 0.01). This study demonstrated improved liver preservation by the use of a simplified colloid-free lactobionate solution containing sodium as the principal cation. The addition of CPZ or NIS to the solution demonstrated the same potency for significant improvement in efficacy of this solution, while NIC was ineffective.
