An experimental study on effects of pyrrolidine dithiocarbamate on ischemia-reperfusion injury in testis
Bibliographic record
Abstract
INTRODUCTION: The aim of this experimental study was to investigate the histopathological and biochemical effects of pyrrolidine dithiocarbamate, an antioxidant and inhibitor of NF-kβ, on ischemiareperfusion injury in rats. METHODS: A total of 21 male Wistar-Albino rats were randomly distributed into three groups as sham group (Group 1), ischemia-reperfusion (I/R) group (Group 2) and I/R with pyrrolidine dithiocarbamate (PDTC) group (Group 3). Left testicles of rats in Groups 2 and 3 underwent testicular torsion of 720° for four hours and 100 mg/kg of PDTC was administered intraperitoneally prior to detorsion in Group 3. An hour after detorsion process, left orchiectomies were performed and 5 ml of intracardiac blood samples were drawn from rats in all three groups. Histopathological examination of testis tissues performed and measurement of superoxide dismutase (SOD) and malondialdehyde (MDA) levels in blood samples were taken. RESULTS: Elevated levels of MDA and decreased SOD activity, together with decreased Johnson tubular biopsy scores consistent with I/R injury were observed in Group 2 (p<0.05). Group 1 and Group 3 were similar in terms of MDA levels, SOD activity, and Johnson scores (p>0.05). CONCLUSIONS: Our results indicated that PDTC may have beneficial effects for alleviation of I/R injury in testicular tissue in rats. Understanding the underlying mechanisms and exploration of its diagnostic and therapeutic potential requires further randomized, controlled trials on a larger scale.

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.
