[The state of the nuclear apparatus of the thyroid gland under conditions of hypofunction of the sympathetic division of the nervous system].
A study was made of the effect of the sympathetic portion of the nervous system on the thyrocyte metabolism. Such morphological criteria as the volume of the thyrocyte nuclei, the amount of DNA in them and structural analysis were used. Three volumetric classes of the nuclei with a different morphological picture were detected in control animals. In depression of the sympathetic portion of the nervous system by administration of antibodies to the growth factor of the nerves there was seen a reduction of the mean nuclear volume and displacement of the volumetric classes in the direction of increase in the quantity of smaller nuclei; electron microscopic studies demonstrated changes in the shape and structure of the nuclei. There were no variations in the amount of DNA.
