Iodine lipid enveloped viruses. Iodine probably attacks surface proteins of enveloped viruses, and it may also destabilise membrane fatty acids by reacting with unsaturated carbon bonds. In medicine, a saturated solution of potassium iodide is used to treat acute thyrotoxicosis. It is also used to block uptake of iodine-131 in the thyroid gland (see isotopes section above), when this isotope is used as part of radiopharmaceuticals (such as iobenguane) that are not targeted to the thyroid or thyroid-type tissues. Iodine-131 (usually as iodide) is a component of nuclear fallout, and is particularly dangerous owing to the thyroid gland's propensity to concentrate
Absent adrenal gland hypoglycemia. SF-1 plays a role in the development of adrenal gland. Single gene polymorphism involving SF-1 gene may have a role in adrenal gland agenesis. Various other factors have also been identified. Absent adrenal gland Absent adrenal gland is a rare condition where the adrenal gland is absent at birth. It should not be confused with adrenal insufficiency or congenital adrenal hyperplasia, where the gland is present but may not be functioning adequately. Due to the absence of adrenal cortex, the condition causes extreme symptoms of adrenal insufficiency at birth due to very low levels of aldosterone and cortisol. The
