Abstract
Sheep were treated with either lymphocyte adhesion molecule (LAM)1-3, an antibody against L-selectin, (40 mg 1 hour before smoke inhalation and 35 mg 24 hours after smoke inhalation; n = 6) or equivalent volumes of 0.9% saline solution (n = 6). After the smoke inhalation injuries, the Pao2/FIO2 ratio declined in both groups until 40 hours after the injuries, when a trend toward improvement was noted in the group that received LAM1-3. Lung lymph flow increased in both groups until 36 hours after the smoke inhalation injuries and then significantly decreased in the group that received LAM1-3. Forty-eight hours after the smoke inhalation injuries, there was a significant decrease in the ratio of wet-dry lung weight and in preservation of the reflection coefficient in the group that received LAM1-3 (P < .05). Histopathologic examination showed no differences between the groups in the pulmonary morphology associated with smoke inhalation. A reduction in splanchnic blood flow was noted in the control group (P < .05); this reduction was attenuated by treatment with LAM1-3. The delayed pulmonary effects and improved splanchnic blood flow suggested that LAM1-3 attenuated the development of a systemically induced secondary lung injury rather than of the primary lung injury associated with smoke inhalation.
