Outline of Final Research Achievements |
The purpose of this study was to determine whether a novel method of hydrogen administration, oral administration of a silicon component, suppresses renal ischemia-reperfusion injury. Six-week-old male SD rats were fed a diet containing fine-grained silicon, and one week later, the left renal artery was blocked for 60 minutes for reperfusion and the right nephrectomy was performed simultaneously. A significant decrease in serum creatinine and urinary protein levels was observed in the silicon group. Oxidative stress markers were significantly decreased in the silicon group. A novel method of hydrogen administration, oral administration of silicon component agents, inhibited renal ischemia-reperfusion injury in rats.

Academic Significance and Societal Importance of the Research Achievements |
生体腎移植において虚血再灌流傷害は回避することができず、拒絶反応を惹起し長期の腎生着率低下と関連する。近年活性酸素種による傷害に対する治療方法の一つとして、水素投与が注目を浴びている。しかし飽和水素水の経口摂取と水素ガスの吸入では広く臨床応用することが困難である。我々はシリコンをナノレベルまで粉砕し水と反応させることにより多量の水素を発生させることに成功した。経口投与することにより腸管内で多量の水素分子を生成して抗酸化作用をもたらす。 我々はこのシリコンナノ粒子の経口投与というこれまでにない革新的な方法で酸化ストレスを抑制し、虚血再灌流傷害の軽減効果が得られることをラットモデルにおいて示した。
