title: [Comparative ultrastructural characteristics of the anterior lobe of the hypophysis, thyroid and gonads in mammals during aging].
abstract: Ultrastructural changes in certain types of adenocytes of old rats, guinea pigs, rabbits and dogs are characterized by specific peculiarities. However, the direction of these changes mainly coincides. The somatotropic function of rats, guinea pigs and rabbits is suppressed, lactotrophic and corticotrophic cells being activated with aging. The phenomenon of the overstrain of gonadotrophic and thyrotrophic cells is registered. Dystrophic changes in the peripheral glands are observed.
