“…This response could be correlated with the increased calcium level which suppresses the release of parathyroid hormone and thus the parathyroidal cells become inactive. Degeneration of parathyroid gland has also been reported from other vertebrates after experimental hypercalcemia induced either by vitamin D administration (Swarup and Srivastav, 1979;Koyama et al, 1984;Rani, -1991b , 1992) or prolactin administration (Srivastav and Rani, 1991a) The present study is the first report from reptiles regarding the effects of prolactin on ultimobranchial body and parathyroid gland. …”

“…The reduction in the parathyroid hormone release by enhanced blood calcium contents induced inactivity of the parathyroid gland leading to degeneration of few cells. Degeneration of parathyroid gland has also been noticed after experimental hypercalcemia in snakes RANI, 1992a, SRIVASTAV et al, 1994) and other vertebrates (KAMEDA, 1970;NUNEZ et al, 1974;SWARUP and SRIVASTAV, 1979;KOYAMA et al, 1984).…”

Abstract. Garden lizards Calotes versicolor were procured and given daily intraperitoneal injections of 30 pmol of 1,25(OH) 2 D 3 /50 g body wt for 30 days. Lizards were sacrificed on the 1 st , 3 rd , 5 th , 10 th , 15 th and 30 th day of the experiment. The plasma calcium levels of C. versicolor remain unaffected after day 1 following 1,25(OH) 2 D 3 treatment. After day 3 the levels increase significantly which progresses up to day 10. Thereafter, the plasma calcium level tends to decrease on day 15 and the levels become normal at day 30. In 1,25(OH) 2 D 3 injected lizards the plasma inorganic phosphate levels remain unaltered up to day 3. After day 5, the value increases significantly. This increase progresses up to day 15. On day 30, the levels become almost normal. The ultimobranchial gland exhibits hyperactivity following 5 day 1,25(OH) 2 D 3 treatment which is expressed by an increase in the nuclear volume and weak staining response of the cytoplasm of ultimobranchial cells. After day 10, the nuclear volume is further increased and some of the cells are exhausted. Following 15 days 1,25(OH) 2 D 3 treatment the nuclear volume records an increase and many degenerating cells are discerned. After day 30, the nuclear volume is almost normal, most cells seem to be recovered and only a few degenerating cells are noticed. After day 10 and day 15 following 1,25(OH) 2 D 3 treatment, the parathyroid glands of C. versicolor show reduced chromaticity of nuclei and a progressive decrease in the nuclear volume of parathyroidal cells. On day 30, the nuclear volume tends to become normal and a few degenerating cells are observed.

“…Inactivity leading to degenerative changes in the parathyroid gland has also been reported in response to hypercalcemia induced by vitamin D or its metabolite treatment in anura (Srivastav and Rani, 1991;Srivastav et al, 2008), reptile (Srivastav and Rani, 1992;Srivastav et al, 1994Srivastav et al, , 2008, bird (Swarup et al, 1986-87) and mammals (Kameda, 1970;Koyama et al, 1984;Nunez et al, 1974;Srivastav and Rani, 1988;Swarup and Srivastav, 1979;Swarup and Tewari, 1978).…”

Columba livia were given daily intraperitoneal injections of 100 pmol of 1,25(OH)(2)D(3)/100 g body wt. for 15 days. Ultimobranchial and parathyroid glands were fixed on 1st, 3rd, 5th, 10th and 15th day of the experiment. Following 1,25(OH)(2)D(3) treatment, the plasma calcium levels of pigeon remain unchanged on day 1. The levels increase significantly after day 3 which progresses up to day 10. The plasma calcium level becomes normal at day 15. The plasma inorganic phosphate levels of Columba livia injected with 1,25(OH)(2)D(3) remain unaffected up to day 3. The levels exhibit a progressive increase from day 5 to day 10. The levels become normophosphatemic at day 15. Up to day 3 following 1,25(OH)(2)D(3) treatment, there is no change in the ultimobranchial gland of Columba livia. The gland exhibits an increased activity after 5 days 1,25(OH)(2)D(3) treatment which is evident by the increased nuclear volume and weak staining response of the cytoplasm of ultimobranchial cells. After day 10, the nuclear volume depicts a further increase and a few completely exhausted cells are discerned. Following 15-day 1,25(OH)(2)D(3) treatment the nuclear volume records an increase and degenerating cells have been observed at certain places. The parathyroid glands of 1,25(OH)(2)D(3)-treated Columba livia remain unaffected up to day 5. After day 10 and day 15, there is a progressive decrease in the nuclear volume of parathyroidal cells and reduced chromaticity of nuclei has been noticed. Moreover, after 15 days few degenerating cells are observed.
