Table 2.

Absolute total and differential cell counts in nasal lavage mean (±SEM), n = 15 unless specifically noted.

Cell variable	PreD1 saline nare	PreD1 LPS nare	PostD1 saline nare	PostD1 LPS nare	PostD3 saline nare	PostD3 LPS nare
TCC/mg	70 (18)	231 (150)	72 (21)+	201 (43)+	213 (83)	147 (35)
PMN/mg	18 (12)	15 (8)#	37 (15)*	136 (38)*,#	175 (79)	82 (23)
Mac/mg	26 (9) n = 9	10 (4) n = 8	7 (4) n = 5	11 (5) n = 8	5 (2) n = 7	14 (6) n = 8

TCC/mg, total cell counts per mg sputum; PMN/mg, polymorphonuclear neutrophils per mg sputum; Mac/mg, macrophage per mg sputum.

^*Significantly higher PMN in LPS nare compared with saline nare after Day 1 challenge (p = 0.001).

^#Significantly higher PMN in LPS nare after Day 1 challenge compared with baseline same nare (p = 0.002).

⁺Significantly higher TCC in LPS nare compared with saline nare after Day1 challenge (p < 0.05).
