[Morphofunctional state of epiphysis in relatively wild and domesticated silver-black foxes during pregnancy].
Morphological indices of changes in the epiphysis activity during pregnancy are analyzed in relatively wild and domesticated silver-black foxes. The diameter of light actively functioning nuclei of pinealocytes increased most significantly and reliably in the end of pregnancy and, at the same time, the area of their surface decreased. These signs witness an enhanced protein synthesis. Unlike other stages of ontogenesis, the degree and dynamics of epiphysis activity during the period of pregnancy were similar in animals of both groups.
