Step tireoidina linked to the existence of two hormones : tiroksina and triyodtironina (in the body are both levovraschayuschimi isomers).
Tiroksin chemically different from triyodtironina molecules in the presence of one additional atom of iodine.
Both hormones have a similar impact on the multi-organism, increase tissue oxygen demand, increase energy processes, promote the growth and differentiation of tissues, affecting the functional state of the nervous and cardiovascular systems, liver, kidneys and other organs and systems, increased glucose intake and reclamation. Effect tireoidnyh hormones may vary depending on the dose. For example, low doses tiroksina have anabolic effects, the same high doses lead to increased degradation of protein. In high doses Thyroid hormones inhibit tireotropnuyu active glands.
Triiodothyronine in 3 - 5 times more effective than tiroksin and act quickly, because the protein binds less blood is transported in the blood mainly in the form of free and quickly crosses the cell membrane. The latent period triyodtironina is 4 to 8 h and tiroksina 24-48 h.
Currently Triiodothyronine obtained by synthetic; Its use as a standalone drug treatment (see Triyodtironina hydrochloride).
Tireoidin and appoint Triiodothyronine (in relatively small doses), with the lack of thyroid function in higher doses (not cause hyperthyroidism, but sufficient to suppress tireotropnoy activity), with the excess tireotropnoy pituitary function.
