Strain differences in toxicity of vitamin K antagonist warfarin in rats
Bibliographic record
Abstract
Warfarin (4-hydroxy coumarin) is Vitamin K (VK) antagonist that inhibits Vitamin K-dependent (VKD) processes, such as blood coagulation. It exerts influence on some non-VKD-related activities as well. In this study, the effect of subacute (30-day) oral warfarin (2 mg L-1 and 1 mg L-1) intake on hematological parameters was examined in two rat strains, Albino Oxford (AO) and Dark Agouti (DA), that differ in their sensitivity to certain chemicals. Greater susceptibility to anticoagulant effect of 2 mg L-1 of warfarin was observed in AO rats and was associated with an increase in relevant hematological parameters in this strain. Although both strains responded to 2 mg L-1 of warfarin with quantitative changes in peripheral blood leukocytes differential bone marrow and lung responses were observed. Strain-related differences in proinflammatory activity of peripheral blood granulocytes and in mononuclear cell IFN-? production were observed. Recognition of differences in quantitative and qualitative effects of oral warfarin on processes other than hemostasis might be of relevance for those humans who are on warfarin therapy.

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.
