Impact of brick-kiln effluent on transamination of tyrosine and mobilization of thyroid hormones in gills and hepatopancreas of Channa punctata (Bloch, 1793) with reference to histo-architecture of the tissues
Bibliographic record
Abstract
Dhubri district of Western Assam, India comprises of large number of brick-kilns yielding huge amount of ashes of burnt or partially burnt coal, supposed to be the major soil and water pollutants of the locality. This study dealt with the histological investigations of the gills and hepatopancreas of Channa punctata Bloch collected from some brick kiln-adjacent wetlands of Dumardaha Pt. II and Geramari Pt. III areas of Dhubri District with supporting observation of lipid and protein peroxidation, mobilization of thyroid and thyroid stimulating hormones, phenylalanine-tyrosine ratio in the tissues and serum ammonia-urea ratio. Studies carried out both in freshly collected fishes, acclimatized fishes and experimental fishes treated with two sub-lethal concentrations of an effluent prepared using brick-kiln refusals collected from the studied areas. During acclimatization process of about first five weeks mortality was observed in some of the collected fishes and rest survived thereafter. Histopathological lesions were marked both in gills and hepatopancreas of freshly collected fishes, were not seen after eight weeks of survival. Similar lesions were again observed in fishes exposed to brick-kiln effluent with varied degree. Rate of lipid and protein peroxidation were observed more in both gills and hepatopancreas of freshly collected fishes and effluent-treated fishes with hypothyroidic conditions and big phenylalanine-tyrosine ratios in comparison to fishes of eight weeks survivability. These indicate healing of tissues at about eight weeks. Reobserving of similar histopathological lesions in the effluent-treated fishes revealed that brick-kiln refusals are toxic to fishes.

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.
