Effect of fasting on hepatocytes cold stored in University of Wisconsin solution for 24 hours.

Although there have been improvements in liver preservation, liver dysfunction still remains a serious consequence of liver transplantation. This may be related to cold ischemic injury since the incidence of dysfunction increases with longer preservation times. However, even some livers preserved for short periods of time (less than 15 hr) develop liver dysfunction. One possible cause may be the lack of adequate nutritional support, and the donor may be exposed to prolonged periods of hyponutrition. In this study, we have compared the effects of fasting on functions of hepatocytes isolated from the rat. Hepatocytes were cold stored in University of Wisconsin solution for 24 hr and analyzed at the end of preservation as well as at the end of rewarming in Krebs-Henseleit buffer for 120 min. The glycogen content of fed cells was 1.57 μmol/mg protein and this was reduced by 95% in cells from fasted rats. After cold storage and rewarming, hepatocytes from fasted rats lost 84.2±2.5% of the total cellular lactate dehydrogenase versus only 32.7±3.8% (P
