Indicators of pituitary-thyroid system and lipid metabolism in female representatives of the Buryat ethnos and Europeoids

Resumo

Specific features of indicators of the thyroid status and blood serum lipoprotein level were revealed in girls and women of the Buryat ethnos and Europeoid race. Buryat versus Europeoid females develop adaptive responses of the pituitary-thyroid part of the neuroendocrine regulatory system (increased free T3 levels in girls and decreased TTH levels in women). Changes in lipid metabolism indicators consist in lower levels of atherogenic cholesterol fractions in Buryat girls and higher levels of cholesterol-containing blood components in Europeoid adolescents. At the older ages, an inverse tendency is observed, characterized by a higher activity of lipid metabolism in females of the indigenous nationality.
