Distribution of MNA and NA added to the culture of LPS-stimulated macrophages

Exogenous compounds (µM)^a	Final concentration^b		The ratio of medium to cytosol concentration
Exogenous compounds (µM)^a	medium	cytosol	The ratio of medium to cytosol concentration
MNA (0.0)	<0.1	<0.5	ND
MNA (10.000)	7991±461	223±32	35.8
NA (0.0)	9±1	47±3	ND
NA (4.000)	3598±87	420±26	8.57

^aMNA or NA was added to the culture of LPS-stimulated Mϕ at the concentrations indicated in brackets. ^bAfter 24 h, supernatant and Mϕ were collected separately and the concentrations of extracellular (medium) and intracellular (cytosol) MNA and NA were measured as described in Materials and Methods. ND — not done.
