The Difference in Effect of Predosing with Antiallergic Compounds between the Rat PCA Model and the Monkey Asthma Model
Bibliographic record
Abstract
DSCG and PRD-92-Ea showed tachyphylaxis in the rat PCA test when a large intravenous dose (40 mg/kg of DSCG and 20 mg/kg of PRD-92-Ea) was given 30 min before administering intravenously the expected effective doses at the time of antigen challenge. This predosing led to a marked loss of effectiveness. Cross-reacting tachyphylaxis was also demonstrated in this model. Predosing rats with DSCG led to a great loss of effectiveness of a subsequent expected active dose of PRD-92-Ea and predosing with PRD-92-Ea had the same effect in preventing the antiallergic action of a subsequent dose of DSCG. The Rhesus monkey (Macaca mulatta) did not exhibit this phenomenon of tachyphylaxis. PRD-92-Ea and DSCG were given intravenously 30 min before and the same dose of 20 mg/kg repeated just before Ascaris suum challenge in the Rhesus monkey asthma model with no loss of their expected effectiveness.

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.
