The ingestion by normal subjects of 3 g of sodium iopodate, which is widely used in routine oral cholecystography, resulted in significant decreases of serum total and free T3 to a nadir on day 4 which averaged 43% and 40%, respectively, below initia

Summary: Gonadotrophin releasing hormone (GnRH) has been used to investigate the hypothalamic-pituitary axis of 25 amenorrhoeic patients with a variety of clinical disorders. The results suggest that studies with GnRH alone do not allow a confident d

Assay of hormones in saliva would be more convenient than assay in blood, but there is no information on the route by which hormones enter saliva, information that would provide insight into the clinical value of such assays. We have examined the mod

We evaluated the fluorescence polarization immunoassay for total thyroxin (T4) and thyroxin-uptake (T-U) in the Abbott "TDx" Analyzer. Between-assay precision was good when we did once-fortnightly calibration and assayed samples in singleton. Measure

Thyrotoxic patients treated with Iodine-131 (131I) often present with low thyroxine (T4), normal triiodothyronine (T3) and raised thyrotropin (TSH) concentrations in serum. We have developed a rat model of this low T4, raised TSH state. Rats were inj

The indirect indices of free-thyroxin concentration (fT4) are of limited effectiveness in diagnosing covert (mild) thyroid disease. We compared measurements of fT4 and of normalized T4 (NT4, the effective thyroxin ratio) in a group of patients being

The timing of blood sample collection in relation to ingestion of thyroxine has been thought to be of no consequence in the assessment of patients receiving thyroxine medication. We have investigated changes in serum thyroid hormones after oral inges

The aim of this study was to determine the specific roles of hypothalamic dopamine (DA), norepinephrine (NE), and serotonin (5-HT) in controlling the release of TSH in hypothyroid and euthyroid states in the rat. Selected ion monitoring (computerized
