The finding may provide a beneficial use of the jellyfish, also known as echizen kurage, which have been a damage-causing plague to the nation's fisheries.
The curative effect of the protein nearly doubles when it is mixed with hyaluronic acid, a chemical usually used for the treatment of osteoarthritis, according to the results of experiments on rabbits undertaken at Tokai University and the Institute of Physical and Chemical Science.
The results of the research are scheduled to be officially reported at a meeting of the Japanese Society for Regenerative Medicine to be held in Tokyo in March.
Kiminori Ushida, head of the institute, and his team succeeded in extracting the protein from the jellyfish
野村海月(クラゲ)と言うクラゲの種類から抽出したムチンと言う蛋白質が、関節の軟骨の再生に有効である事が解ったそうだ。
このクラゲの大量発生は越前の漁師を困らせ、話題となった事が有った。(福井県は越前クラゲとは呼んで欲しくないそうだが。)
東海大学の行った動物実験ではその蛋白質にヒアルロン酸を加えると更に効果が増大すると言う。
同実験で人工的に関節炎を生じさせた動物にヒアルロン酸をクラゲから抽出した蛋白質に加え注入し、10週間経過を観察した結果、関節の炎症が改善され、軟骨も再生していることを確認したと言う事である。
