Figure 4From: In vivo models of lung neutrophil activation. Comparison of mice and hamstersBronchoalveolar differential cell counts following sequential application of LPS and fMLP in hamsters. Animals were intratracheally challenged with LPS (0.5 mg/kg intratracheally) or PBS (100 μl). Twenty four hours after, hamsters were intratracheally challenged with 0.25 mg/kg of fMLP or 100 μl of vehicle (1% DMSO in PBS). Two hours after the second challenge, animals were sacrificed and bronchoalveolar lavage performed. Data are expressed as mean ± SEM from 5–6 hamsters per group. Significance (P < 0.05), indicated by (*) or (#) is versus PBS-challenged/Vehicle-treated hamsters and LPS-challenged/Vehicle-treated hamsters, respectively.Back to article page
