Figure 3. — SNGFR values (black dots) on the y axis represent SNGFR values from the present experiments; SNGFR values at LP flow of 30 nl/min come from our earlier study in which the effect of raising LP flow on early proximal flow rate was determined ⁹. The negative lines connecting SNGFRs represent the TGF relationship that, for reasons of simplicity, is drawn as a linear relation, although it is known to be sigmoidal ^19,
20. The slope of the positive line reflects proximal reabsorption, and it was calculated assuming a TF/Piothalamate ratio of 2. The intersects between the TGF and reabsorption relationships indicated by the open circles represent steady-state values for reabsorption and SNGFR ¹⁹.
