Steroid hormone and antihormone induced changes in the pineal and adrenocortical karyomorphology and cell proliferation in mice ( Mus musculus )
Bibliographic record
Abstract
In the present investigation steroid hormones, estradiol and testosterone and non-steroidal antihormones, tamoxifen and flutamide induced responsiveness in pineal and adrenal karyomorphology and cell proliferation activity was studied in post pubertal male mice (Mus musculus). Estradiol was injected at a dose of 5µg, testosterone 100 µg, tamoxifen 500 µg and flutamide 2 mg per 100 gm body weight administered intramuscularly in all cases for ten consecutive days. Control mice were similarly injected with oil vehicle 0.3 ml of peanut oil intramuscularly for same duration. The results indicated that except testosterone, all other treatments with estradiol, tamoxifen and flutamide caused significant hyperactivity of both the pineal and the adrenal gland associated with significantly increased cell proliferation activity. On the contrary testosterone administration was inhibitory to pineal - adrenal karyometric and mitotic incidence values. It was concluded that in male post pubertal mice both pineal and adrenal shows antagonistic response towards estradiol and testosterone administration. Although tamoxifen showed estrogen agonistic behaviour, flutamide on the reverse induced pineal and adrenal cytophysiological stimulation. Such stimulatory response was antagonistic to the inhibitory response shown by pineal and adrenal karyomorphology and cell proliferation following testosterone administration.

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.
