Paper Abstract

Two-dimensional micro scale thermal analysis is proposed for the measurement of the latent heat released from the cultured vascular endothelial cells during freezing by use of high-speed infrared focal plane arrays. The thermo graphically observed latent heat spreading over the tissues and the inter- or intracellular thermal diffusion were detected with a spatial resolution of 7.5mm. The temperature distribution in time and space in each endothelial cell was influenced by both the self-release and intercellular diffusion of latent heat. The effect of cryo-protective agent on the cell suspension of bovine fetal aorta endothelial cell (BFAEC) was examined by the observation of latent heat during the repeated freezing processes.
