Secretion of a Hyperemia-Inducing Moiety by Mitogen or Glycogen Stimulated Mononuclear Inflammatory Cells of Sheep and Rabbit
Bibliographic record
Abstract
A nonlymphokine mediator of hyperemia has been shown to be secreted by both rabbit peritoneal exudate cells stimulated with 5% glycogen and by concanavalin A treated cells from afferent lymph of sheep. This mediator is not stored in an active form in cells, but is either activated or synthesized de novo in response to antigenic or mitogenic stimuli. Secretion of the mediator is inhibited by culturing cells in the presence of dexamethasone but not indomethacin. However, expression of the activity is inhibited by pretreatment of the assay animals with indomethacin, suggesting a two-step induction of hyperemia. A similar mediator was found to be secreted by sheep and rabbit alveolar lavage cells, and rat peritoneal exudate cells. The presence of this hyperemia-inducing activity from diverse species suggests a fundamental role in controlling blood flow. Alteration of blood flow may modulate delivery of blood-borne cells and factors to sites of chronic inflammation.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
