Time course of reversal from pulmonary protection after cessation of ATL146e. NY1DD mice were treated with ATL146e (10 ng/kg/minute, 3 days osmotic pump). Pulmonary parameters were measured on days 3, 4, and 7 after the cessation of ATL146e infusion. All parameters measured (vascular permeability [EBD], breathing measurements [TV, FOB], and pulmonary cell infiltrates) returned toward NY1DD baseline levels on day 4, 1 day after the cessation of ATL146e treatment, and returned to baseline levels by day 7. The solid and dashed lines represent the mean ± SEM of breathing parameters in C57BL/6 mice. Data were analyzed by 1-way ANOVA with Neuman-Keuls posttesting. *P < .05.
