STUDIES ON THE THYROID UPTAKE OF I<SUP>131</SUP> I. EFFECT OF PITUITARY HORMONES

Vasopressin and thyroid function in the rat: the effect of oestrogens

“…VASOPRESSIN AND RAT THYROID An increased uptake of 131I by the thyroid of the rat was reported to follow injection of vasopressin by Dubreuil & Martini (1956) and Ogawa et al (1956). In the present study the same dose and schedule of injections of vasopressin as those used by Dubreuil & Martini (1956) was followed, but no increased L311 was observed in the experimental animals as compared with the controls.…”

Influence of the Neurohypophysialhormone on the Plasma Pb131i Level During Repeated Bloodcollections in Rats

“…Smaller dose induced a suppression on the mouse also 6). 1. In normal rats, plasma PB 131 I was maintained at the initial level or slightly elevated during repeated blood collections under ether anesthesia, which was arbitrarily called" maintenance of plasma PB 131 I".…”

Hypothalamic Neurohumoral Control of Pituitary Function

“…hypertonic saline and warming in the guinea-pig also stimulate thyroid activity (Feuer & Harris, unpublished observations). Although some investigators disagree (Rose et al 1960), there are suggestions in the literature that vasopressin increases thyroid function (Ogawa et al 1956, Dubreuil & Martini 1956, Bottari 1957) and may be acting on the release of TSH. In some preliminary studies, we found that acetic acid extracts of median eminence tissue increased thyroid function in the rabbit (Schindler, Harris & Garcia, unpublished observations).…”
