Developmental and patterns of pituitary and plasma TSH in the normal and hypothyroid female rat.

Abstract:

:The developmental patterns of thyroid-stimulating hormone (TSH) was examined in female Long-Evans rats by radioimmunoassay of pituitary and plasma from 5 through 80 days of age. The effects of hypothyroidism on normal TSH levels were examined in animals radiothyroidectomized at birth. Control animals showed a peak in circulating TSH levels at day 12 followed by lower levels through day 30, and even lower levels at day 80 when values were those of adult animals. Hypothyroid females had higher plasma TSH levels than controls from days 10 through 30 with no distinct peak at day 12. Pituitary content reached a peak at day 18 and was always higher in control than hypothyroid animals.
