Figure 1. Time- and concentration-dependent effect of exposure to halothane on ouabain-sensitive86Rb influx in alveolar type II cells. Cells were exposed to halothane concentrations of 1, 2, or 4% for up to 4 h, and ouabain-sensitive Rb influx was measured. Data represent the means +/- SD of four experiments done in triplicate. All values for each concentration of halothane were significantly different from the value of the respective control group at time zero (P < 0.05).
