THE article by Xu et al.  entitled “Halothane and Isoflurane Augment Depolarization-induced Cytosolic CA2+Transients and Attenuate Carbachol-stimulated CA2+Transients” was published in the June 2000 issue of the Journal (Anesthesiology 2000; 92:1746–56) with an error in the labeling of figure 4. The corrected figure and legend appear below. The authors regret this error.

Fig. 4. (A–E ) Representative traces of [CA2+]cyt-changes with sequential stimulation using 100 mm KCl followed by 1 mm carbachol (CAB). (A ) Control. (B–F ) Cells were pretreated for 5 min with 10 mm caffeine (CAF). (B ), 1 μm thapsigargin (TG) (C ), 10 mm CAF and 1 μm TG (D ), 10 mm CAF and 1 μm CAB (E ), or with 1 μm TG and 1 μm CAB (F ). (G, H ) Statistical summary. Values presented are mean ± SEM (n = 2–19). The significance of the differences among different groups was tested using the Student-Neumann-Keuls test and labeled as follows:*P < 0.05 to the control group; $P < 0.05 to the TG group. Fig. 4.
