Effect of IL-1 receptor antagonist on O3 induced changes in NGF and SP levels in bronchoalveolar lavage fluid. Animals were instilled with saline or IL-Ra (200 ng/ml) prior to O3 exposure. NGF and SP levels were measured in bronchoalveolar lavage fluid by an ELISA 24 h after O3 exposure (2 ppm, 3 h). (A) NGF levels and (B) SP levels in the lung lavage. Values are means ± SE of 4–6 mice/group. Asterisk indicates significant difference in NGF and SP levels between saline-and IL-1 Ra-treated animals, p ≤ .05.
