| Outline of Final Research Achievements |
A big result in this research was that breeding method of a leech Ozobranchus jantseanus was established in this study. From a past and this studies, it was known that the leech extract (including carnosine) not having an effect to control ice crystal growth. On the other hand, a lot of damaged cells in the organ frozen leech was found in the leech showing high ability to restore. These results suggest that the leech dose not restrain damage due to ice crystalization in freezing, but having a high reconstruction characteristics in thawing. Indeed, there is a possibility that carnosine having antioxidant ability found by metabolic loam analysis participates in it. The applied effect such as carnosine improving the lyophilization tolerance of the lactic acid bacterium may be one side to support it.
