TLDR
The parathyroid glands suffer from degenerative changes due to its inactivity under chronic hypercalcemia and shows progressive hypertrophy up to 20th day of the treatment, while the ultimobranchial cells show feeble staining response.Abstract:
Psittacula psittacula when subjected to long term hypercalcemia by intramuscular injections of vitamin D2 (20,000 I.U.) on alternate days and by increasing dietary calcium, exhibit a rise in the serum calcium level after 10, 20 and 30 days of treatment as compared to their corresponding controls. The ultimobranchial cells show progressive hypertrophy up to 20th day of the treatment. From 20th day till the end of the experiment (30 days) these cells show feeble staining response. The parathyroid glands suffer from degenerative changes due to its inactivity under chronic hypercalcemia.read more
