Ultimobranchial body and parathyroid gland of the frog, Rana tigrina in response to calcitonin administration.
The effects of salmon calcitonin (0.25 MRC mU/g body wt) on the serum calcium and phosphate levels as well as on the activity of ultimobranchial body and parathyroid glands was investigated in the frog, Rana tigrina for 15 days. The hormone evokes hypocalcemia (on day 1 and day 3) which is followed by a significant hypercalcemia on day 10. Thereafter, the level of calcium decreases again on day 15. Calcitonin induces hypophosphatemia (on day 3 and day 5). Thereafter, hyperphosphatemia is recorded on day 10. By day 15 normal serum phosphate value is achieved. After treatment with calcitonin, the ultimobranchial body becomes inactive and the parathyroid glands get activated.
