Isotopes of iodine and non-radioactive materials can be described as "cold." There are instances in which cold iodide is administered to people in order to prevent the uptake of hot iodide by the thyroid gland. For example, blockade of thyroid iodine uptake with potassium iodide is used in nuclear medicine scintigraphy and therapy with some radioiodinated compounds that are not targeted to the thyroid, such as iobenguane (MIBG), which used to image or treat neural tissue tumors, or iodinated fibrinogen, which is used in fibrinogen scans to investigate clotting. These compounds contain iodine, but not in the iodide form. However, since they may
Adrenal gland disorder Adrenal gland disorder Adrenal gland disorders (or diseases) are conditions that interfere with the normal functioning of the adrenal glands. Adrenal disorders may cause hyperfunction or hypofunction, and may be congenital or acquired. The adrenal gland produces hormones that affects growth, development and stress, and also helps to regulate kidney function. There are two parts of the adrenal glands, the adrenal cortex and the adrenal medulla. The adrenal cortex produces mineralocorticoids, which regulate salt and water balance within the body, glucocorticoids (including cortisol) which have a wide number of roles within the body, and androgens, hormones with testosterone-like function. The
