PCNA positivity in the mesencephalic matrix areas in the adult of a Teleost, Carassius carassius L.
Adult Teleosts still display karyokinetic activity involving also the central nervous system so that physiological neurogenesis does not cease when adult body size is reached but later. In the brain this is due to the persistence in several districts of neural type elements in the ependymal epithelium or in the area surrounding it, which combine to form matrix zones or matrix areas. These eleme...

متن کاملMixed germ cell-stromal testicular neoplasia in a crucian carp (Carassius carassius L.): a case report
This report documents a case of spontaneously occurring gonadal neoplasm in a crucian carp (Carassius carassius L.) caught in the wild. On the basis of the histopathological findings, the neoplasm was diagnosed as a mixed germ cell-stromal testicular neoplasia (gonadoblastoma). Teleosts generally resemble other vertebrates in their basic susceptibility to developing neoplastic lesions. A large ...

متن کاملEffects of prolonged anoxia on electrical activity of the heart in crucian carp (Carassius carassius).
The effects of sustained anoxia on cardiac electrical excitability were examined in the anoxia-tolerant crucian carp (Carassius carassius). The electrocardiogram (ECG) and expression of excitation-contraction coupling genes were studied in fish acclimatised to normoxia in summer (+18°C) or winter (+2°C), and in winter fish after 1, 3 and 6 weeks of anoxia. Anoxia induced a sustained bradycardia...
