Example Sentences:

Urinary calcium excretion was greater in sham-operated rats given vitamin D than in uremic rats.
(12) As there was no elevation of the osteoblastic activity in knee joints with developing osteoarthrosis, it would appear that bone sclerosis associated with the disease was due to decreased osteoclasis.
(13) Modes and surgical treatment include osteoclasis and percutaneous pinning for long-bone deformities in the infant and, in the child older than two years of age, segmentation and the use of telescoping rods.
(14) An excess of bone surfaces were covered by osteoid seams, all of which showed active mineralisation, indicating a relative increase in osteoblastic activity; osteoclasis seemed to be unaffected.
(15) In rats given 5 units of 1,25-(OH)2D3, osteoclasis was markedly increased.
(16) Eight of fourteen patients elected some form of surgical revision, most commonly closed osteoclasis with restoration of femoral length, followed by the insertion of a statically locked nail.
(17) The results accord with hypotheses that (1) osteoclasis of scaffoldtype woven bone is impaired in mi mi, (2) that osteoclastic cells are derived through circulating monocytes from hematopoietic stem cells, and (3) in mi mi this defect can be overcome by a transplant of normal hemopoietic stem cells.
