| Outline of Final Research Achievements |
Ascorbic acid is one of the major antioxidants and has been regarded to play multiple roles in antioxidant defense system, having both roles of pro- and anti- oxidant. It is thus important to investigate its reaction mechanism in vivo, for oxidative stress disease research.
In this study, an imaging approach with Overhauser enhanced MRI (OMRI) was developed for imaging ascorbic acid radical in mice. Magnetic resonance spectroscopic characterization of ascorbic acid radical was investigated and OMRI resonators were developed to maximize detection sensitivity for ascorbic acid radical. In results, ascorbic acid radical were imaged with OMRI after administration of the radical solution i.m., i.v., i.p. and s.c.
