[Chronobiological aspects of TSH secretion in control subjects and in subjects with primary hypothyroidism].
The circadian rhythm in plasma TSH concentration was demonstrated in euthyroid subjects and in treated hypothyroid patients. Our results suggest that two hypothalamic areas, involved in TRH secretion, are responsables in basal as well impulsive pituitary TSH dismission.
