[Electron microscopic findings during hypothermic storage preservation of the liver. II. (author's transl)].

Porcine livers were preserved by simple hypothermic storage for 6 h using plasma-protein-fraction 5%, albumin 5%, Collins C2, and Ringer-lactate followed by a morphometric evaluation of the electron-microscopic changes. The morphometric parameters reflecting swelling of mitochondriae showed the most pronounced changes and were suited best for reproduction. The best result was achieved by using Collins C2-storage. The endoplasmic reticulum was found to be only slightly swollen in all preservation solutions investigated here, at the same time a degranulation of granular endoplasmic reticulum could be demonstrated. The increase in volume of lysosomes per unit-volume was not significant.
