Table 2.

The mean fluorescent values of lactoferrin expression on 7 h EC and 2 h EC night tear PMNs.

		2 h EC night tear PMNs	7 h EC night tear PMNs
Lactoferrin	Unstimulated	120 ± 82	285 ± 107*
	fMLP stimulated	173 ± 105	324 ± 200
	Ratio of stimulated vs unstimulated	1.4 ± 0.4	1.2 ± 0.3
IL-8Rs	Unstimulated	25 ± 7	17 ± 4*

Tear PMNs were stained with lactoferrin, and immediately characterized by flow cytometry. Results are presented as mean ± standard deviations. n = 6.

*Significantly different from the 2 h night PMNs (p < 0.007).
