제안 방법
- The test samples were dissolved in DMSO and adjusted to sample concentrations 20, 50 and 100 µg/㎖ by diluting with the growth medium.
대상 데이터
- japonica was collected from the experimental forest at the Forest Research Institute, Gangwon Province in January of 2005. Collected bark (WSE0513) was processed at the Herbarium of Department of Forest Biomaterials Engineering, Kangwon National University. Samples were air-dried at room temperature for 3 weeks, and then ground to fine powder for further use.
- 7 cells. Experiments were performed in triplicate.
- NMR spectra were obtained by a Bruker Avance DPX 400 MHz NMR spectrometer using CD3OD. FAB-MS was recorded with a Micromass Autospec M363 Spectrometer at the Central Laboratory, Kangwon National University.
- Lipopolysaccharide (LPS), NG -monomethyl-L-arginin (NMMA), Griess reagent (equal volumes of 1% sulfanilamide in 5% phosphoric acid and 0.1% naphtylethylenediamine-HCl), 3-(4,5-dimethyl-thiazol-2-yl)-2,5-diphenyl-tetrazolium bromide (MTT), Dulbecco’s modified Eagle medium (DMEM), 10% fetal bovine serum (FBS), penicillin (100 U/㎖), streptomycin (100 µg/㎖) and phosphate buffered saline (PBS) were purchased from Gibco Laboratories (Gaithersburg, MD, USA).
이론/모형
- The antioxidant activity of individual samples was determined on the basis of their radical scavenging activity in the presence of DPPH free radical using the method introduced by M. S. Blois (Blois, 1958) with slight modification. Samples of different concentrations (20∼160 µg /㎖) were added to a solution of DPPH (0.
