| Outline of Final Research Achievements |
The purpose of this study is inspection of the effectiveness in the spinal cord injury treatment by porcine liver decomposition (PLD), and identification of the active ingredients. We showed that PLD beyond certain quantity is effective for spinal cord injury by the animal experiment using the rat spinal cord injury model. We think the validity of this PLD doesn't depend on new nervous revival, and is promotion of the recovery of left nerves without being cut. Moreover, it was revealed that these effects were complex action of plural phospholipids included in PLD in in vitro experiments.

| Academic Significance and Societal Importance of the Research Achievements |
ラット脊髄損傷モデルを用いた動物実験でPLDの脊椎損傷に対する有効性が一定量以上の投与量である事が示せたことで、今後、リン脂質をベースとした新たな脊椎損傷のための治療薬開発が可能であると考えている。更に、神経細胞に対してリン脂質にまだ明らかになっていない未知の機能があるとも考えられ、今後の展開が期待できる。
