| Outline of Final Research Achievements |
The radioactive Cesium released by the accident of Fukushima Daiichi Nuclear Power Station destribute to Abukuma Mountains in Fukushima. The effects of expose of radiocesium on masu salmon were examined.Following results were obtained.
1)Positive corelation was observed betaeen the concentration of 137Cs in muscle and meranomacrophage in spleen. The histrogical deformities were also observed in gill. 2)the hemogrobin concentration decreased according to the increase of 137Cs concentration in muscle. This phenomenon also observed in rearing experiment. 3)Point mutations were observed in mitochondria DNA in the offspring obtained from the females which were collected from Mano River. These were not observed in the offspring obtained from the female which was rearing in Fukushima Prefectural Inland Water experimental Station. 4)Decrease of expression level in the gene which affecting to the apoptosis was observed.
These results are plobably caused by exposition to radioactive materials.
