Small-sized newborn dogs skeletal development: radiologic, morphometric, and histological findings obtained from spontaneously dead animals

BACKGROUND Very little is known about neonatal skeletal development in small-sized purebred dogs. In order to improve this knowledge, 27 spontaneously dead puppies belonging to small-sized breeds were enrolled in this study for radiologic, histological and morphometric investigations. RESULTS The appearance of the limb secondary ossification centers and the onset of their formation were clear...

Experimental Animals and Induction of Brain Tumors. Newborn Syrian hamsters obtained from Engle's Labora

In vitro cultivation of medulloblastoma cells was success fully established from hamster brain tumors induced by simian adenovirus SA7. These tumor cells possess morpho logical features in cultures that are very similar to those of the original tumor. Both tubular and rosette growth pat terns were evident. At the ultrastructural level only small numbers of cytoplasmic organdies could be detecte...

Cartilage Canals in Newborn Dogs: Histochemical and Immunohistochemical Findings

Cartilage canals (CCs) are microscopic structures involved in secondary ossification centers (SOCs) development. The features of CCs were investigated in the humeral and femoral proximal epiphyses of small-sized newborn dogs (from premature to 28 days after birth) with histochemical and immunohistochemical approaches. Masson's Trichrome revealed a ring-shaped area around CCs, which changes in c...

Radiologic findings of thoracic trauma

INTRODUCTION Chest trauma may be blunt or penetrating and the chest is the third most common trauma region. It is a significant cause of mortality. Multidetector computed tomography (MDCT) has been an increasingly used method to evaluate chest trauma because of its high success in detecting tissue and organ injuries. Herein, we aimed to present MDCT findings in patients with blunt and penetrati...
