The nuclei become more irregular inshape and size, and cell-regeneration cannot keep pace with cell-destruction. Fibroblasts take the place of the dead parenchymacells, and the fibrous stroma of the organ becomes greatly in-creased (fig. 24). The glands powers of compensation and cell-regeneration have failed, its reserve force is exhausted. Thisprocess results in myxcedema, which may follow any prolongedtoxic excitation of the thyroid ; it is a natural sequel of such 72 PATHOLOGY excitation in all cases of Graves Disease that do not recoverspontaneously, or in which death does not supervene. In all. Fig. 21.—Section of thyroid from a case of Graves Disease.
