Hepatic histidase activity in adult female rats is twice that in adult male rats. Hypophysectomy and thyroidectomy result in a significant increase in hepatic histidase activities in males, but not in females. This effect on histidase is reversed by the exogenous administration of tri-iodothyronine, but not by ectopic pituitary glands or purified pituitary hormones.
In normal conditions, serum (or plasma) iodine is largely composed of thyroxine and iodide with small quantities of thyroactive iodothyronines, such as 3: 5: 3'-tri-iodothyronine and 3: 3'-di-iodothyronine (Gross and Pitt-Rivers, 1952; Roche, Lissitzky, and Michel, 1952a and b; Roche, Michel, Nunez, and Wolf, 1956). Another relatively less active compound, 3: 3': 5'-tri-iodothyronine, is presen...
The concentrations of the iodothyronine metabolites T(4), T(3), 3,5-diiodothyronine (3,5-T(2)), 3,3'-diiodothyronine (3,3'-T(2)), reverse T(3) (rT(3)), 3,3'-T(2) sulfate (3,3'T(2)S), and T(3) sulfate (T(3)S) were measured in 12 regions of the brain, the pituitary gland, and liver in adult male rats. Quantification of iodothyronine was performed by RIA following a newly developed method of purif...
