Effects of sodium ferulate on nitric oxide synthase and cyclooxygenase in colon of colitis rats
Bibliographic record
Abstract
AIM To investigate the anti-inflammation protective effects of sodium ferulate (SF) on colitis rats and its mechanism. METHODS The colitis model of rats was produced by intracolon enema with acetic acid. SF and 5-ASA were used intracolonically for a week. The colon mucosadamage index (CMDI) was evaluated. Nitric oxide (NO), myelopexoxidase (MPO), prostaglandin (PGE_2), and the levels of expression of constitutive nitric oxide synthase(cNOS), induce nitric oxide synthase (iNOS), cyclooxygenase-1 (COX-1), cyclooxygenase-2 (COX-2) and nuclear factor-kappaBp65(NF-κBp65) in the rats colon were detected by corresponding kits and immunohistochemical technology. RESULTS SF (200,400,800 mg·kg -1 ) can decrease the extents of CMDI and the levels of NO, MPO, PGE_2, the expression of cNOS, iNOS, COX-2, and NF-κBp65 in model group in a dose-dependent manner while the expression of COX-1 changes littlely. CONCLUSION SF is a NOS and partial selective COX-2 inhibitor and show therapeutic effect on colitis in rats.

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.
