Table 2. Effect of F991 on leukocyte accumulation in the lung air spaces 24 h after DNBS challenge of vehicle or DNFB-sensitized BALB/c mice.

			Leukocytes in BAL (cells/lung × 104)
	n	DNFB	Total cells	PMN	MONO
PBS	6	–	2.20 (1.22–3.15)	0.03 (0.01–0.05)	2.16 (1.14–3.10)
	6	+	2.19 (1.35–2.71)	0.13* (0.09–0.24)	2.06 (1.24–2.60)
F991	5	–	3.10 (2.01–3.45)	0.06 (0.03–0.12)	2.89 (2.49–3.41)
	6	+	2.70 (1.95–3.15)	0.05 (0.03–0.08)	2.64 (1.90–3.07)

Leukocytes (PMN, polymorphonuclear cells; MONO, mononuclear cells) were determined in BAL fluid of vehicle (–) or DNFB-sensitized (+) mice. Results are expressed as median (minimum – maximum). Significant differences between vehicle- and DNFB-sensitized groups are indicated (*, P < 0.05 vs. vehicle-sensitized mice).
