The state of the guanylate cyclase mechanism of vasodilatation before and after thyroidectomy in the patients presenting with toxic goiter
Keyword(s):
The state of the guanylate cyclase activity of myocytes was evaluated from the increment in the diameter of the brachial artery in response to the exogenous administration of nitroglycerin (#D^NO) in 64 samples obtained from 44 patients. A total of 23 studies were carried out during thyrotoxicosis decompensation, 28 ones in the phase of medicamental thyrotoxicosis, and 13 within 5-6 days after thyroidectomy. The guanylate cyclase activity of myocytes was found to correlate with the production of vascular endothelium factors. Thyroidectomy in the patients with toxic goiter and reduced guanylate cyclase activity of myocytes was associated with the statistically significant increase of endothelium-independent vasodilatation.
