Abstract
Behavior of ice crystals and cells in the biological tissues during the warming after rapid-cooling was investigated microscopically in time-series using a confocal laser scanning microscope with a fluorescent dye. Attention was paid on the recrystallization of intracellular ice crystals to increase the mechanical damage of the tissues. Size and number of the ice crystals were measured from the image-date of ice crystals and statistically analyzed to obtain frequency, average, and standard deviation of the size of ice crystals, total amount and number density of ice crystals, etc. in time-series during the warming. Influence of the warming rates on these characteristics was made clear.
