Table 4 The Effect of NTCKS Water-extract on Prostaglandin E2 Production of RAW 264.7 Macrophage Cells

Concentration (㎍/㎖)	PGE2 production (pg/well)
Control	821.24 ± 1.63
LPS + 50	827.86 ± 24.78
LPS + 100	830.27 ± 18.24
LPS + 150	767.63 ± 12.53*
LPS + 200	746.35 ± 11.05*

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
