Ossifying fibroma in a canary (Serinus canaria).
A 1-year-old male canary (Serinus canaria, Jibber breed), with a protuberance on the left tibia was referred to the clinic. The bird was not able to use the affected foot to stand on its perch. Results of radiographs revealed a radio-opaque hard tissue mass. The canary was euthanatized and submitted for necropsy. On histopathologic examination, the mass was diagnosed as an ossifying fibroma tum...
متن کاملPCNA-negativity in the telencephalon of adult female songbirds (Serinus serinus): absence of signs of normal proliferation.
In a recent study, we demonstrated the persistence of normal proliferation in the telencephalon of adult male songbirds (Serinus serinus), as shown by the expression of Proliferating Cell Nuclear Antigen (PCNA), a test that uses monoclonal antibodies to reveal cells in the S phase. Near the start of the breeding season, this proliferation was observed in circumscribed areas of the ventricular e...
متن کاملSigns of normal proliferation in the telencephalon of adult male songbirds (serinus serinus), as shown by PCNA-positivity.
The immunocytochemical expression of Proliferating Cell Nuclear Antigen (PCNA) (a cycline that coadjuvates DNA polymerase delta) becomes appreciable in the cell cycle when DNA synthesis occurs; hence cells in the S phase can be revealed by means of monoclonal antibodies. Therefore, PCNA can be considered a marker of proliferation, and numerous literature reports have demonstrated the reliabilit...

متن کاملExtraskeletal osteoma in a canary (Serinus canaria)
Osteoma is an uncommon bone tumor in avian species and other animals. A 2-year-old male canary (Serinus canaria) with a history of an oval mass in the left wing for several months was examined. Radiographs showed a radio-opaque mass. Upon the bird's owner request, the canary was euthanatized and submitted for necropsy. The histopathologic examination revealed numerous trabeculae consisting of b...
