Morphometric analysis of structural renal alterations and beneficial effects of aminoguanidine in acute kidney injury induced by cisplatin in rats
Bibliographic record
Abstract
Since cisplatin-induced nephrotoxicity has very important clinical consequences, the purpose of this study was to determine the potential protective effect of aminoguanidine on the acute kidney injury caused by cisplatin. Experiments were done on 40 Wistar rats divided into four groups. The CIS group received cisplatin in a single dose of 8 mg/kg, while the CISAG group received the same dose of cisplatin and aminoguanidine (100 mg/kg) by intraperitoneal injections. Animals in the AG group received only aminoguanidine (100 mg/kg) and those in the C group received saline. Quantitative evaluation of structural and functional alterations in the kidneys was performed by analysis of biochemical and parameters of oxidative stress and by histological and morphometric analysis of renal sections. Histological sections of kidney showed structural damage of proximal tubules and glomeruli that were induced by cisplatin. Morphometric analysis revealed statistically significant differences in the area of proximal tubules and the size and cellularity of glomeruli between the CIS and CISAG groups. Glomerular basement membrane thickness was increased in the CIS group, while aminoguanidine attenuated these changes in the CISAG group of rats. Our results suggest that aminoguanidine acts protectively and repairs structural and functional damage of kidney by engaging the existent antioxidative potential at the level of renal tissue.

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.
