...H. Devlin; M.W.J. Ferguson Ovariectomy has been shown to produce osteoporosis in the femur of the rat. 11-month-old Sprague-Dawley rats were either ovariectomized or given a sham operation.The loss of calcium in the femur of the rats was compared with two indices of osteoporosis, the ponderal index...

...F. Matsumoto; Y. Miyamoto; M. Nagayama In order to obtain more insight into the physiologic mechanism of endochondral ossification, histological changes occurring in the mandibular condylar cartilage of growing rats fed on a low-calcium diet were investigated by light and electron microscopy...

...S. Emura; S. Shoumura; M. Utsumi; D. Hayakawa; T. Yamahira; K. Terasawa; A. Tamada; M. Arakawa; H. Isono The effects of different ages on large vacuolar bodies in the parathyroid glands of golden hamsters after short-term treatment with calcium were investigated. In the parathyroid glands...

...S. Chen; D.R. Eisenmann; A.E. Zaki; S.H. Ashrafi Calcium distribution in secretory ameloblasts was studied in rat incisor enamel in which mineralization was temporarily disturbed by injection of either fluoride or cobalt. Pyroantimonate precipitates of calcium were analysed morphometrically...

...Yasutoku Kogaya; Kuhei Furuhashi We investigated the ultrastructural localization of calcium in progenitor predentine and preodontoblasts of developing rat molar tooth germs using the potassium pyroantimonate technique. At the precalcification stage, antimonate reaction product was sparsely...

...Yoshiro Takano; Saburou Matsuo; Satoshi Wakisaka; Hiroyuki Ichikawa; Shinji Nishikawa; Michio Akai The localization of calcium in the enamel organ of rapidly frozen, freeze-substituted rat incisors in early-stage amelogenesis was examined by a histochemical calcium-staining method. In secretory...

...E.S. Lindenbaum; B.A. Peretz; D. Beach Microbiopsies of 38 specimens of human Fallopian tube fimbrial epithelium obtained during hysterosalpingectomy operations were processed for electron microscopic observation. Calcium localization was demonstrated utilizing the pyroantimonate-osminium-tetroxide...

... in the early luteal phase was mostly amorphous electron-lucid material which failed to stain with PAS, alcian blue and the Millon reaction. However, reaction products of acid phosphatase as well as calcium precipitate were scattered in them as discrete granules. The same type of globule was found in early...
