...B. Keller; E.M. Schraner; P. Wild Parathyroid cells responded to estradiol application in rats by increment in surface area of the compartments concerned with parathyroid hormone secretion, i.e. the rough endoplasmic reticulum, Golgi complex and secretory granules [1]. We thus compared...

...P. Wild; C. Bächler; G. Bertoni; E.M. Schraner The ultrastructure of parathyroid glands of hypophysectomized rats in normo- and hypocalcaemic conditions was qualitatively and quantitatively analysed. Parathyroid glands of both intact and hypophysectomized rats comprised cells of similar shape...

...Ajai Kumar Srivastav; Krishna Swarup The thyro-parathyroid complex of foxes was cut into serial sections. For demonstration of calcitonin (C) cells the sections were stained by hematoxylin and eosin, PAS-hematoxylin, Davenport’s silver impregnation and lead hematoxylin. The C cells are oval...

...Ajai Kumar Srivastav; Krishna Swarup Porcine calcitonin (CT) (0.5 MRC unit daily) was administered intraperitoneally to house shrews, Suncus murinus, for 42 days. The changes in serum calcium and phosphate levels as well as the light microscopical alterations of the parathyroid and calcitonin cells...

...Krishna Swarup; Ajai Kumar Srivastav; Nagendra Prasad Tewari The present report deals with the occurrence of calcitonin cells (C cells) and cysts in the parathyroid IV of Suncus murinus . Histological preparations of the thyro-parathyroid complex reveal that (i) the parathyroid IV exhibits C cells...

...Shakti P. Kapur A fine-structure study of the parathyroid proper and adjacent tissues has been performed in the gerbils. The chief cells were observed in three phases of the secretory cycle. The resting chief cells contained prominent lipid droplets, mitochondria and an atrophied Golgi apparatus...

.... Parathyroid chief cells showed hypertrophy from 21 to 35 days of the treatment. From day 28 to the close of the experiment they released their secretory product. After 42 days of experimental treatment a growth-promoting effect of calcitonin was observed (increase in body weight and femur weight). © 1980 S...
