[Bioelectrical activity and the ultrastructural characteristics of thyroid cell cytoplasmic membranes in different forms of thyrotoxicosis].

Bioelectrical activity of the thyroid epithelium cells was studied by microelectrode analysis in patients with various forms of thyrotoxicosis, as well as in those with the disease developed against the background of organic affections of the central nervous system. The value of bioelectrical potentials of the thyroid cells in patients with various forms of thyrotoxicosis, including that coursing against the background of encephalopatheis, proved to be practically the same, and, at the same time, considerably lower than in control examinations. Cytoplasmic membranes of the thyroid cells retained, irrespective of the form and genesis of basedowification, the same structural organization, which, however, differed from that in intact thyrocytes.
