The present study was undertaken to provide basic data on endochondral ossification for the axis in developing Miniature Schnauzers. This study was determined to the morphological features and development of growth plast in the axis of this experimental animals by histological and histochemical methods. The axis from 2 healthy Miniature Schnauzers(postnatal 6hr, 5week) was used. The obtained results were as follows : 1. In 5-week-old Miniature Schnauzer, the axis consisted of 4 separate ossification centers : centrum l, intercentrum 2, centrum 2 and epiphysis. Intercentrum 2 was intercalated between centrum 1 cranially, centrum 2 caudally. 2. The space of centrum 1 was more broader than the other ossification centers. 3. The zone of reserved chondrocytes was more extensive than the zone of proliferative chondrocytes, trabeculation was weakly observed, however, the proximal epiphyseal plate of axis was actively trabeculation observed in the zone of calcified chondrocytes. 4. Eighteen columns of chondrocytes were observed in the centrum 1 and five to seven columns of chondrocytes were observed in the centrum 2 of Miniature Schnauzer(postnatal 5 week) 5. A positive reaction to alcianophility was observed in all the territorial matrix at the zone of hypertrophic chondrocytes in this experimental animals. |
