Outline of Final Research Achievements |
Bone tissue is relatively hypoxic, and oxygen administration improves bone metabolism. Glucocorticoid-induced osteoporosis (GIO) is one of the most frequent secondary osteoporosis, and thereby novel, low-cost, convenient treatment is desired. Ultra-fine bubble (UFB; <200 nm in diameter) has several unique properties, and tested in various medical fields such as drug delivery. We investigated that oxygen ultra-fine bubbles (OUB) saline peritoneal injection prevents bone loss of GIO in mice. Moreover, OUB inhibits osteoclast differentiation and function in a dose-dependent manner in vitro. The efficacy and adaptation of OUB to other hypoxia-related diseases is also expected to be investigated in the future study.
