Volume of the cell nuclei of the ependyma of the infundibular recess was measured in 30 female and 30 male water frogs (Rana esculenta L.) obtained from their natural environment, taking into account the phase of the annual cycle. Karyometry of the ependymal cell nuclei in the infundibular recess in males and females showed statistically significant differences of volume (activity) in the annual cycle. The largest volume of nuclei of the ependymal cells in females and males was observed in the first decade of April (end of hibernation), and the smallest in the first decade of September (end of the period of active life). Activity of nuclei of cells from the infundibular recess clearly correlated with gonadal development.
在考虑年度周期阶段的情况下，对从自然环境中获取的30只雌性和30只雄性食用蛙（泽蛙）漏斗隐窝室管膜细胞核的体积进行了测量。对雄性和雌性漏斗隐窝室管膜细胞核的核测量显示，在年度周期中体积（活性）存在统计学上的显著差异。雌性和雄性室管膜细胞核的最大体积出现在4月的第一个十年（冬眠结束时），最小体积出现在9月的第一个十年（活跃生活期结束时）。漏斗隐窝细胞的细胞核活性与性腺发育明显相关。
