Does alkalosis per se or does the associated lactacidemia determine the rate of PAH or Diodrast transport? How is net renal uptake of lactate related to Tmpah? Tmpah, renal extraction of I131-Diodrast (Ediod) and net renal lactate uptake were studied in anesthetized (pentobarbital) dogs. In clearance experiments, Tmpah is elevated (facilitated) by isohydric increases in blood [lactate]; alkalosis has no further effect on the facilitated (by lactate) Tmpah. In contrast to the effects of alkalosis on Tmpah, no rise in Ediod occurs during alkalosis. However, when Ediod is depressed by [PAH] sufficiently high to achieve Tmpah, a rise in blood lactate does enhance Ediod. Thus, lactate enhances Ediod when the transport mechanism common to it and PAH is saturated. Net renal uptake of endogenous lactate is decreased during alkalosis; no net renal production of lactate has been observed. Therefore, the increases in Tmpah and Ediod are not related to a rise in net renal uptake of lactate but are probably more related to the blood [lactate]. It is postulated that Tmpah and Ediod may be more dependent on the metabolic mixture presented to the kidney, and thus on extrarenal metabolism, than on intrarenal distribution of blood flow or rate of renal blood flow.

Intrarenal Distribution

Intrarenal distribution of blood flow was assessed with radioactive albumin microaggregates (MA) in three cortical zones of the dog kidney. The experimentally obtained zonal fractions of total renal blood flow were compared with predicted zonal blood flow fractions obtained in a mathematical model. The maximal degree of skimming that could possibly occur in a single experiment was estimated. The analysis showed that local blood flow in the inner cortical zone was maximally underestimated by 17% because of skimming of MA, and in the outer cortical zone the blood flow was maximally overestimated by 13% with the method of radioactive MA uptake. Renal uptake of 201Tl was measured simultaneously in exactly the same locations. Paired measurements of intrarenal blood flow distribution by MA and Tl uptake methodologies showed that local blood flow assessed with MA in the inner cortical zone was significantly lower than that obtained with 201Tl and that a higher blood flow rate was obtained in the outer cortical zone with MA compared with 201Tl. This disparity could be accounted for by the effect of skimming of MA as predicted by the model.
