Effect Of Selenium On "Low T_3 Syndrome" Inhepatic Failure, Emir Dönder, Mehmet Çay, Necip İlhan, Giyasettin Baydaş, Mustafa Naziroğlu

Triiodothyronine occurs especially in 5'-monodeiodination of thyroxin in peripheral tissues. Deiodination of thyroxin mainly occurs in the liver. The enzyme which catalyzes this reaction is a seleno-enzyme. Deiodinase enzyme activity and the triiodothyronine level decrease in selenium deficiency. After the occurrence of chronic hepatic failure by carbon tetrachloride in rats, we gave sodium selenite to these rats. Then, we tried to evaluate the changes in thyroid hormone levels. Liver function tests, thyroxin and triiodothyronine levels, and hepatic 5'-deiodinase and glutathione peroxidase enzyme activities were measured. Triiodothyronine levels in the carbon tetrachloride group and carbon tetrachloride + selenium group were significantly …

An attempt was made to determine the effects of selenium and vitamin E supplementation on thyroid hormones in lambs. Sixteen Akkaraman lambs were used and divided equally into four groups. One group was used as a control. Second group was fed with selenium (sodium selenite, 0.3 mg kg -1 feed). Third group was fed with vitamin E (DL-a tocopheryl acetate, 250 mg -1 feed) and fourth group was fed with selenium (sodium selenite, 0.3 mg/ kg -1 feed) + vitamin E (DL-a tocopheryl acetate, 250 mg kg -1 feed) supplemented diet. Serum selenium, vitamin E and plasma thyroxine (T 4 …

This study, we aimed to examine the levels of vitamin A, E, selenium, zinc, copper, phosphorus, magnesium and total protein in blood of aborted ewes. Aborted and control (non aborted) Akkaraman ewes were used in living different regions of Elazığ. The levels of selenium, zinc, copper, phosphorus, magnesium, total protein, vitamin A and E were measured in plasma samples of aborted and control animals. Present findings showed that concentration of vitamin E, selenium, copper, magnesium (P
