Research Abstract

In the septic rat model administered lipopolysaccharide(LPS), we established the method to measure in real time serum vitamin C levels by using an electron spin resonance spectrometer. Twenty four hours after high dose LPS, serum vitamin C decresed remarkably and the inflammatory response increased.
The new antioxidant, ETS-GS which has very strong antiinflammatory and antioxidant effects tended to inhibit serum vitamin C loss and the infllammatory response. The hormones of pituitary and adrenal, however, didn't increase significantly. Therefore, I could not figure out the relationship between the ETS-GS and the hypothalamus-pituitary-adrenal axis.
In the future, I will plan to use the SMP30 knockout mouse which cannot synthesize vitamin C like human and continue this study.
