Na and Cl transport and short-circuit current in rabbit ileum
Summary Na and Cl fluxes and short-circuit current (I sc) in rabbit ileum have been studied as a function of ionic concentrations in HCO3-free solutions. Both net Na flux (J net Na ) andI sc show similar saturation functions of [Na] at fixed [Cl]. They show no significant difference between zero and...

| 520 | |a Summary Na and Cl fluxes and short-circuit current (I sc) in rabbit ileum have been studied as a function of ionic concentrations in HCO3-free solutions. Both net Na flux (J net Na ) andI sc show similar saturation functions of [Na] at fixed [Cl]. They show no significant difference between zero and 112mm Na but at 140mm NaI sc is significantly greater than theJ net Na . Net Cl transport, secretion, is observed only at 140mm Na and is approximately equivalent to the difference between theI sc andJ net Na . The transcellular mucosa-to-serosa Na fluxes measured at 140 and 70mm Na do not differ significantly from the correspondingI sc. The net Cl flux varies with [Cl] at fixed [Na] whileI sc is virtually not affected by [Cl]. These results suggest that the absorptive Na transport process is electrogenic and responsible for theI sc and that the secretory fluxes of Na and Cl are coupled, require high [Na], vary with [Cl], and do not contribute toI sc. K-free solution abolishes theI sc after a prolonged lag. Finally, the effect of a low resistance shunt pathway on active Na absorption is examined with a four-compartment model. | ||

Na and Cl transport and short-circuit current in rabbit ileum |
| abstract |
Summary Na and Cl fluxes and short-circuit current (I sc) in rabbit ileum have been studied as a function of ionic concentrations in HCO3-free solutions. Both net Na flux (J net Na ) andI sc show similar saturation functions of [Na] at fixed [Cl]. They show no significant difference between zero and 112mm Na but at 140mm NaI sc is significantly greater than theJ net Na . Net Cl transport, secretion, is observed only at 140mm Na and is approximately equivalent to the difference between theI sc andJ net Na . The transcellular mucosa-to-serosa Na fluxes measured at 140 and 70mm Na do not differ significantly from the correspondingI sc. The net Cl flux varies with [Cl] at fixed [Na] whileI sc is virtually not affected by [Cl]. These results suggest that the absorptive Na transport process is electrogenic and responsible for theI sc and that the secretory fluxes of Na and Cl are coupled, require high [Na], vary with [Cl], and do not contribute toI sc. K-free solution abolishes theI sc after a prolonged lag. Finally, the effect of a low resistance shunt pathway on active Na absorption is examined with a four-compartment model. |

Both net Na flux (J net Na ) andI sc show similar saturation functions of [Na] at fixed [Cl]. They show no significant difference between zero and 112mm Na but at 140mm NaI sc is significantly greater than theJ net Na . Net Cl transport, secretion, is observed only at 140mm Na and is approximately equivalent to the difference between theI sc andJ net Na . The transcellular mucosa-to-serosa Na fluxes measured at 140 and 70mm Na do not differ significantly from the correspondingI sc. The net Cl flux varies with [Cl] at fixed [Na] whileI sc is virtually not affected by [Cl]. These results suggest that the absorptive Na transport process is electrogenic and responsible for theI sc and that the secretory fluxes of Na and Cl are coupled, require high [Na], vary with [Cl], and do not contribute toI sc. K-free solution abolishes theI sc after a prolonged lag. Finally, the effect of a low resistance shunt pathway on active Na absorption is examined with a four-compartment model.</subfield></datafield><datafield tag="533" ind1=" " ind2=" "><subfield code="f">Springer Online Journal Archives 1860-2002</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Tai, Yuan-Heng</subfield><subfield code="4">oth</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Desjeux, Jehan-F.</subfield><subfield code="4">oth</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Danisi, Giustina</subfield><subfield code="4">oth</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Curran, Peter F.</subfield><subfield code="4">oth</subfield></datafield><datafield tag="773" ind1="0" ind2="8"><subfield code="i">in</subfield><subfield code="t">The journal of membrane biology</subfield><subfield code="d">1969</subfield><subfield code="g">31(1977) vom: Jan., Seite 189-208</subfield><subfield code="w">(DE-627)NLEJ18899419X</subfield><subfield code="w">(DE-600)1459323-3</subfield><subfield code="x">1432-1424</subfield><subfield code="7">nnns</subfield></datafield><datafield tag="773" ind1="1" ind2="8"><subfield code="g">volume:31</subfield><subfield code="g">year:1977</subfield><subfield code="g">month:01</subfield><subfield code="g">pages:189-208</subfield><subfield code="g">extent:20</subfield></datafield><datafield tag="856" ind1="4" ind2="0"><subfield code="u">http://dx.doi.org/10.1007/BF01869404</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">GBV_USEFLAG_U</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">ZDB-1-SOJ</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">GBV_NL_ARTICLE</subfield></datafield><datafield tag="951" ind1=" " ind2=" "><subfield code="a">AR</subfield></datafield><datafield tag="952" ind1=" " ind2=" "><subfield code="d">31</subfield><subfield code="j">1977</subfield><subfield code="c">1</subfield><subfield code="h">189-208</subfield><subfield code="g">20</subfield></datafield></record></collection>
