Effect of Pregnenolone-16α-Carbonitrile on Bilirubin- and Sulfobromophthalein-Binding to Hepatic Y and Z Proteins in the Rat
Bibliographic record
Abstract
Pregnenolone-16 alpha-carbonitrile (PCN), administered twice daily p.o. for 3 days at a dose level of 20 mumol/100 g body weight, significantly enhances in vivo binding of 14C-bilirubin and sulfobromophthalein (BSP) to hepatic Y and Z proteins in female Charles River CD rats. 14C-bilirubin-binding to Y protein showed a 61% increase, while binding of the same moiety to the Z protein fraction was augmented by 59%. BSP-binding in vivo demonstrated rises of 114 and 71% in relation to Y and Z proteins, respectively. These data correlate well with previous investigations in which PCN was found to have a beneficial influence on experimentally induced hyperbilirubinemias and, furthermore, there is an indication that phenobarbital, another potent microsomal enzyme inducer, acts via a similar mechanism.

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.
