Energetic recovery from hypothermic preservation in the rat liver

Changes in energy metabolism induced by norepinephrine were observed in liver perfused immediately after dissection and in liver stored in Euro-Collins solution at 0 degrees C for 24 hr. Oxygen consumption, glucose output, ATP content, and tissue pH were measured in isolated perfused rat liver at 37 degrees C. In fresh liver, a two-fold increase in glucose output and oxygen consumption was induced by norepinephrine (1 microM), while changes in ATP content and tissue pH were minimal. In stored liver, the cumulative increments in glucose output and oxygen consumption induced by norepinephrine were 30 and 27% those of fresh liver, respectively. ATP content of the unstimulated liver was 76% that of the fresh liver, then decreased to 50% during stimulation. A transient decrease in tissue pH (0.14 pH unit) was significant compared with that of fresh liver. These results suggest that norepinephrine stimulation is useful for assessing energetic and functional recovery of reperfused liver following hypothermic storage.

閉塞性黄疸肝肝切除17例を対象として, 術後経過に影響をおよぼすと考えられる術前因子 (肝切除率, 術前血清総ビリルビン値, 減黄率b値, 血清アルブミン値, プロトロンビン時間, ヘパプラスチンテスト, ICGR15, K, Rmax, 50g経口糖負荷試験) と術後経過との関連についてretrospectiveに検討を加えた.減黄率b値, 血清アルブミン値, プロトロンビン時間の良好な症例では, 術後順調に経過することが多かった.術前総ビリルビン値, ICGR15が高値を示した症例では手術死亡が多くみられた.50g経口糖負荷試験において, 正常型では全例術後順調に経過したが, linear型では手術死亡例が多く, これらの因子は肝切除術の術後経過を反映していると考えられた.
