| Outline of Final Research Achievements |
For experimental study on nonfreezing preservation of living cells under high hydrostatic pressure, an experimental device for in-situ observation of a chamber that can control hydrostatic pressure and temperature (lower than 0℃), was developed. It was confirmed that the device has enough performance of load pressure, temperature-control, and in-situ observation.
Living eggs of killifish were employed for freezing experiment. Freezing processes of eggs were observed under various hydrostatic pressure using the developed device. Also, damage of eggs were evaluated by hatch status of the eggs. It was found from the experiments that a hatch limit depended on the pressure and the temperature, and that the pressure and temperature history influenced the hatch limit.
