Table 3 The Effect of NTCKS Water-extract on NO Production of RAW 264.7 Macrophage Cells

Concentration ㎍/㎖)	NO production (㎛)
Control	85.3 ± 6.3
LPS + 50	83.8 ± 3.8
LPS + 100	79.2 ± 4.0
LPS + 150	73.3 ± 6.0*
LPS + 200	67.8 ± 5.9*

Valuses are the mean ± SD of the three independent experiments.
Control : treated with LPS (10㎍/㎖)
50, 100, 150 and 200 : treated with LPS and NTCKS (50, 100, 150 and 200㎍/㎖)
* p < 0.05 compared to control
