Microscopical Observation on Postmortem Autolysis in Liver of Korean Native Cattle

To observe sequential postmortem autolysis in liver of Korean native cattle, liver placed in controlled environment chamber at $23-27.5^{\circ}C$ was treated after various intervals and observed with light microscope. The nuclear fading accompanied by margination of the chromatin in the hepatocytes appeared by 3 to 6 hours, and reduction of the cytoplasmic stainability and haryolisis began at 15 hours after death. Pyknosis of Kupffer's cells was noted by 3 to 20 hours, thereafter followed the decrease in staining of nuclei, but the nuclei were visible until 50 hours after death. Sinusoids and space of Disse were markedly distended at 10 hours, thereafter spaces of Disse were more dilatable than sinusoids. A large number of the erythrocytes in blood vessels were lysed, and the cytoplasmic stainability was largely reduced at 25 hours and nearly disappeared at 40 hours after death.
