title: [Electron microscopic study of the epiphysis in the hen in different age periods].
abstract: Electron microscopic investigation of the epiphysis in 1 and 2 years old hens revealed that pineocytes are rich in mitochondria, ribosomes, granular endoplasmic network, Golgi apparatus, synapses. In contrast to 1-year hens, large amounts of lipofuscin granules and lysosomes were found in older animals. The data obtained reveal intensive hormone formation and oxidation-reduction processes in the epiphysis of birds.
