Kinetic analysis and partitioning of sodium and chloride influxes across the gills of sea water adapted trout.

Abstract: SUMMARY1. Sodium and chloride influxes across the gills of sea water adapted trout were studied with the perfused isolated head technique.2. The haemodynamic scheme describing anastomoses between efferent gill arteries and the filamentous sinus was confirmed and utilized to determine partitioning of sodium and chloride influxes.3. Two routes of sodium and chloride entry were demonstrated, one lamellar and the other sinusal. The lamellar sodium and chloride fluxes are respectively 133 ± 21*8 and 271 + 43-7 pteq… Show more

“…In ordinate logarithm of the quantity of radioactivity appearing per unit of time in the external (e) and in the internal (A) lamellar compartment. Insert represents the graphical determination of the fast exponentials (Girard & Payan, 1977a) Figure 3 shows the curves of radioactive discharge from the intermediate compartment into the external medium and into the perfusion liquid in the absence of adrenaline. Analysis of these curves demonstrates that for water two exponentials are obtained having different slopes for the external and internal compartments.…”

“…The unidirectional diffusion fluxes across these two barriers at equilibrium (J21 and Jga), as well as overall unidirectional transepithelial flux (J), were also measured and are expressed as ml-min-l.100g -~ (see Girard & Payan, 1977a). The size of the pool (ml-100g -1) participating in transepithelial water flux is given by the equation (Girard & Payan, 1977a) transflux pool -K21 +K23"…”
