Table 1. Attenuation of proinflammatory cytokine production by NaPB in primary mouse microglia.

Cytokine (ng/mgprotein/24 h)	Treatment
	Control	LPS	LPS+NaPB (0.1 mM)	LPS+NaPB (0.2 mM)	LPS+NaPB (0.5 mM)	NaPB (0.5 mM) only
TNF-α	0	18.4+3.1	16.8+1.5	12.7+0.8	8.6+1.1a	0
IL-1β	0	11.2+2.9	9.9+1.4	7.5+1.1	5.3+0.6a	0

Primary microglia preincubated with different concentrations of NaPB for 6 h were stimulated with LPS for 24 h followed by quantification of TNF-α and IL-1β in supernatants by ELISA. Results are mean + SD of three independent experiments.
