The table should have appeared as follows:

Table 5.  Comparison of transport properties for vascular endothelia

Preparation Umbilical vein endothelial cells Aortic endothelial cells Pulmonary artery endothelial cells Brain microvascular endothelial cells Other studies This study Basal pH with HCO3– 7.26 7.2 6.9, 7.18** 7.15 Basal pH without HCO3– 7.21 7.2, 7.08* 7.02 6.83 7.1 Intrinsic buffer capacity near 7.1 15 mM 69 mM 25 mM Near pH 7.1  Na+/H+ exchange 17 µM s–1 Yes Yes*, yes** 4 µM s–1  Na+-dependent HCO3– influx yes Yes 25 µM s–1   Cl– dependent 17 µM s–1 suggestion   Cl– independent 17 µM s–1  Na+-independent Cl–/HCO3– Yes See note* 28 µM s–1 when  exchange reversed by Cl– removal After NH4Cl prepulse#. Yes*  Na+/H+ exchange > 50 µM s–1 at pH 6.9 Yes* Yes Yes, yes** 270 µM s–1 at pH 6.36  Na+-dependent HCO3– influx Yes Yes* Yes   Cl– dependent > 34 µM s–1 at pH 6.9 Yes* Yes but data not shown Net transport None None None secretion: apical (blood) to basolateral (brain) References Sun et al.

(2000) Nozik-Grayck et al. (2003)* Hsu et al. (1996)** Faber (1998)* All HCO3– transport indicated has been shown to be either DIDS or H2DIDS sensitive, all Na+/H+ exchange has been shown to be sensitive to either EIPA or DMA, (#) or other form of imposed acidification. Nozik-Grayck et al. (2003) demonstrated ·O2–/HCO3– exchange which was presumed to be mediated by the Na+-independent Cl–/HCO3– exchanger, AE2.

Also on page 776, right column, the increase in pH cited on the 5^th and 4^th line from the bottom should read: 0.63 ± 0.06 to 0.17 ± 0.04 by 2 µM ethoxzolamide and to 0.18 ± 0.02
