Abstract

Sexually mature Rana temporaria L. frogs were captured in their natural habitat in seven stages of the the annual cycle. The volume of the nuclei of neurocytes of the pars dorsalis of the tuber cinereum containing lipofuscin pigment underwent significant changes in the course of the year. In both sexes the nuclear volume of the neurocytes was greatest in the terminal stage of winter sleep (1st decade of March), and smallest at the beginning of active life (3rd decade of May). The accumulation of lipofiscin pigment varied parallel to the changes in mean volume of the neurocyte nuclei of the pars dorsalis of the tuber cinereum.

摘要

性成熟的欧洲林蛙在其自然栖息地被捕获，处于一年周期的七个阶段。含有脂褐素色素的灰结节背侧部神经细胞核的体积在一年中发生了显著变化。在两性中，神经细胞核的体积在冬眠末期（3月的第一个十年）最大，而在活跃生活开始时（5月的第三个十年）最小。脂褐素色素的积累与灰结节背侧部神经细胞核平均体积的变化平行。
