Fig. 4. Effect of halothane on lactate dehydrogenase (LDH) release by alveolar type II cells. Recombinant murine interleukin-1β-stimulated rat alveolar type II cells were exposed during 4 h to 0, 0.5, 1, and 1.5 minimum alveolar concentration of halothane. LDH activities were then measured in cell supernatants. Results are expressed as the percentage of values obtained for air-exposed cells, mean ± SD; †P < 0.05 versus air.
