Summary

PORK LIVER WAS SUBJECTED TO REPEATED FREEZING: 253 K (-20 DEG C) AND THAWING: 278 K (5 DEG C). ULTRASTRUCTURE WAS COMPARED TO THAT OF REFRIGERATED PORK LIVER. LIVER CELLS DETERIORATED MORE WITH FREEZING AND THAWING (F-T) THAN WITH REFRIGERATED STORAGE (R-S). AFTER ONE CYCLE F-T, HEPATOCYTE ORGANELLES WERE DAMAGED AND CYTOPLASMIC COMPONENTS APPEARED IN THE SINUSOIDS. AFTER FOUR CYCLES F-T, MEMBRANES WERE EXTENSIVELY DAMAGED AND SINUSOIDS CONTAINED ORGANELLES. THE TISSUE ORGANIZATION WAS STABLE DURING SIX DAYS OF STORAGE, ALTHOUGH CELL STRUCTURE DETERIORATED. EVIDENCE FROM ULTRASTRUCTURE INDICATED THAT DRIP FROM F-T LIVER AND R-S LIVER AROSE FROM DIFFERENT KINDS OF TISSUE DAMAGE.
