Role of oregano on bacterial enzymes in 1,2-dimethylhydrazine-induced experimental colon carcinogenesis
Bibliographic record
Abstract
Colon cancer incidence is higher in developed countries than in developing countries. We determined the effect of oregano (Origanum vulgare L.) on fecal bacterial enzyme activities in 1,2-dimethylhydrazine (DMH)-induced experimental colon carcinogenesis in rats. Male Wistar albino rats were divided into 6 groups and all animals were fed with a high-fat diet (20% fat in the diet). Group 1 served as control and group 2 animals received 60 mg.kg(-1) body weight (b.w.) oregano daily for 15 weeks. To induce colon cancer, DMH (20 mg.kg(-1) b.w.) was injected subcutaneously once a week for the first 4 weeks (groups 3-6). In addition, oregano was administered at 20, 40, or 60 mg.kg(-1) b.w. each day orally for the entire 15 weeks (groups 4-6). We analyzed the fecal bacterial enzyme activities and found it to be significantly higher in the group treated with DMH alone than in the control group. Oregano supplementation at all 3 doses significantly suppressed the bacterial enzyme activities and modulated oxidative stress significantly compared with the unsupplemented DMH-treated group. Results of our present investigation therefore revealed that oregano markedly inhibited DMH-induced colon carcinogenesis and that the optimal dose of 40 mg.kg(-1) b.w. was more effective than either the higher or lower doses.

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.
