“…It is considered that starvation affects functional activity in the water-clear cells of the parathyroid gland. Albright et al (1934) first reported the waterclear cell hyperplasia of the parathyroid glands in patients with primary hyperparathyroidism, and several authors have described the ultrastructure of the water-clear cell (Holzmann and Lange, 1963;Sheldon, 1964;Faccini, 1970;Roth, 1970;Thiele and Pichlmayr, 1974;Altenâhr, 1981).
