Increase in Renal and Urinary Low and High Molecular Weight Kininogens during Chromate-Induced Acute Renal Failure in the Rat: Evidence for Renal Kininogen Production
Bibliographic record
Abstract
In the present study, we investigated the plasma, urinary and intrarenal concentrations of low and high molecular weight kininogens during sodium chromate (25 mg/kg body weight)-induced acute renal failure (ARF) in the rat. Urinary kininogen underwent a transient increase with a maximum on day 7 (78 +/- 22 versus 4.2 +/- 1.6 ng bradykinin/mg creatinine) whereas plasma kininogen did not and glomerular filtration rate decreased (92 +/- 8 versus 895 +/- 70 microliters/min). The tissue level of kininogen was enhanced both in the cortex (1,319 +/- 123 versus 86 +/- 8 pg bradykinin Eq/mg protein) and in the medulla (1,673 +/- 138 versus 44 +/- 9 pg bradykinin Eq/mg protein) but more in the medulla (36 +/- 4- versus 15 +/- 3-fold). As plasma kininogen level was unchanged and glomerular filtration rate decreased, the increase in both renal concentration and urinary excretion of kininogen probably reflects stimulated renal production of kininogen in this model of ARF. Whether the evoked renal production of kininogen results from a local inflammatory response only or may subserve another physiological purpose remains to be elucidated.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
