Evaluation of Protective Effect of Methyl Sulfonyl Methane on Colon Ulcer Induced by Alendronate
Bibliographic record
Abstract
Background: Bisphosphonates represent a new class of drugs that have shown very promising therapeutic efficacy in the treatment of a number of diseases associated with abnormally accelerated bone resorption including osteoporosis, Paget’s disease, and hypercalcemia of malignancy. As an increasing number of these drugs become available for clinical use in the treatment of the millions of individuals with these skeletal diseases, evidence is becoming available that their chronic usage may be associated with a number of gastrointestinal side effects, such as diarrhea, abdominal pain and inflammation, and erosions and ulceration of the upper gastrointestinal tract. Methyl sulfonyl methane (MSM) which is used for osteoarthritis was used to prevent bisphosphonates ulceration. Our objective was to study the preventive effect of MSM against colon ulcer induced by Alendronate (ALN) in rats. The experiments had been done on 8 white wistar rats for each group. The gastric ulcer has been induced by administration of Alendronate (20mg/kg/day) by gavage for 4 days. MSM (400mg/kg/day) has been given for the protective group for 4 days before administration of Alendronate. The ulcers in rats' colon were examined histologically and microscopically. The results showed that administration of MSM before Alendronate inducing ulcer led to a reduction in ulceration and showed significant difference comparing with morbidity group. Conclusion: MSM (400 mg/kg/day) has protective effect of colon ulcer induced by alendronate.

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.
