[Lipid peroxidation in patients with diffuse toxic goiter and hypothyroidism].

A study made in 77 patients with different form of thyropathy revealed increased blood plasma and erythrocyte content of lipid peroxidation products, such as diene conjugates and TBA-active producers. The plasma chemiluminescence got more intense as well. Different mechanisms for the lipid peroxidation activation in patients presenting with thyroid hormone abundance or deficiency have been analyzed.

[Characteristics of the clinical picture, hormonal status and humoral immunity in older patients with diffuse toxic goiter].

Radioimmunoassays, immunological and radioreceptor methods were used for a study of the levels of T3, T4, TSH, thyroglobulin, antibodies to thyroglobulin and microsomal antigen, immunoglobulins suppressing thyrotropin binding in 92 patients with diffuse toxic goiter aged over 50. There was discrepancy between the prevalence of severe types of disease in this group of patients and an insignificant rise of T3 and T4 levels. Changes in the immune status pointed to an increase in immunodeficiency which became progressive with aging of the organism, and increasing sensitivity to damaging agents.

[Status of the hypothalamo-hypophyseal system in patients with diffuse toxic goiter].

Disorder of function of the hypothalamus-thyroid system in patients with diffuse toxic goiter is accompanied by change of the hormonal activity of the hypothalamohypophyseal-adrenocortical and hypothalamohypophyseal-ovarian systems. It is particularly marked in persons with heredity aggravated by thyroid diseases or/and diabetes mellitus.
