Following hemodynamic measurements, lungs isolated from rats exposed to systemic LPS (5mg/kg) for 4 hours with or without intracerebroventricular rimonabant treatment, were separated into left and right halves. Right lungs were homogenized, and supernatants, 20 μg/lane, were Western blotted. A) Representative blots are shown of IL-6, VCAM, Myeloperoxidase (MPO); C=control, R=rimonabant, L=LPS and RL=rimonabant treatments + LPS. B) The Western blot band densities of IL-6, in relative density units (RDU). C) The Western blot band densities of VCAM, in RDU. D) The Western blot band densities of MPO in RDU. Data are mean ± S.E.M. Significance was at P<0.05. * = significantly different from control. # = significantly different from its LPS-only group.
