[Thyroid hormones and melatonin as means of antioxidant therapy]
Abstract:
The possibility of involvement of thyroid hormones and melatonin in cell protection from damage by active oxygen forms (hydroxyperoxide, superoxide radical, and hypochlorite) was investigated. The intensity of inhibition of luminol-dependent chemiluminescence induced by neutrophils and active oxygen forms in the presence of hormones was evaluated. Antioxidant activities of the enzymes were compared with that of glutathione. Probable mechanisms of antioxidant effect of the studied hormones are discussed.

Synthesis and Regulation of Thyroid Hormones
Upon reaching the thyroid gland, TSH stimulates the follicular cells' active uptake of iodide ions from the blood. The ions diffuse to the apical surface of the cells and are oxidized to iodine. The iodine is then...
Functions of Thyroid Hormones
TH is indispensable for the normal development and maturation of the skeletal, muscular, and nervous systems during fetal and childhood growth. It facilitates bone mineral turnover and regulates protein synthesis in developing tissues, contributing significantly to overall growth and...

Sedatives and Hypnotics Drugs: Miscellaneous Agents
Melatonin congeners like ramelteon (Rozerem) and tasimelteon (Hetlioz) selectively bind to melatonin receptors (MT1 and MT2) and thus mimic the actions of melatonin, a hormone that regulates sleep-wake cycles. Tasimelteon is primarily used for non-24-hour sleep-wake disorder, common in blind patients. They are also used to treat conditions like insomnia...
