Antilithogenic influence of dietary capsaicin and curcumin during experimental induction of cholesterol gallstone in mice
Bibliographic record
Abstract
Spice bioactive compounds, capsaicin and curcumin, were both individually and in combination examined for antilithogenic potential during experimental induction of cholesterol gallstones in mice. Cholesterol gallstones were induced by feeding mice a high-cholesterol (0.5%) diet for 10 weeks. Groups of mice were maintained on a lithogenic diet that was supplemented with 0.015% capsaicin/0.2% curcumin/0.015% capsaicin + 0.2% curcumin. The lithogenic diet that contained capsaicin, curcumin, or their combination reduced the incidence of cholesterol gallstones by 50%, 66%, and 56%, respectively, compared with lithogenic control. This was accompanied by reduced biliary cholesterol and a marginal increase in phospholipid in these spice-fed groups. Increased cholesterol saturation index and cholesterol : phospholipid ratio in the bile caused by the lithogenic diet was countered by the dietary spice compounds. The antilithogenic influence of spice compounds was attributable to the cholesterol-lowering effect of these dietary spices in blood and liver, as well as a moderate increase in phospholipids. Decreased activities of hepatic glutathione reductase and glutathione-S-transferase caused by the lithogenic diet were countered by the combination of capsaicin and curcumin. The increased lipid peroxidation and the decreased concentration of ascorbic acid in the liver that was caused by the lithogenic diet was countered by the dietary spice compounds, individually or in combination. Thus, while the capsaicin and curcumin combination did not have an additive influence in reducing the incidence of cholesterol gallstones in mice, their combination nevertheless was more beneficial in enhancing the activity of hepatic antioxidant enzyme ─ glutathione reductase in the lithogenic situation. The antioxidant effects of dietary spice compounds are consistent with the observed reduction in cholesterol gallstones formed under lithogenic condition.

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.
