Cellular composition of adrenal cortex of adult male and female hamster was evaluated and parallel quantitative ultrastructural studies were performed. The adrenal cortex of adult male hamster contained more parenchymal cells than that of female and the difference depended mainly upon the number of the zona glomerulosa and zona fasciculata cells. Moreover, cells and nuclei of the zona reticularis were markedly larger in male animals. Ultrastructural observations of both male and female adrenal glands did not reveal any significant difference; however, stereology showed that the volumes of mitochondrial compartment and membrane space, as well as the surface areas of mitochondrial cristae and smooth endoplasmic reticulum tubules were significantly higher in the male hamster zona reticularis cells. Cortisol output by adrenal slices and homogenates per unit weight of the gland was higher in male than in female hamster. On the ground of these data, it seems conceivable that the observed sex-differences in the rate of cortisol output by hamster adrenal gland depend upon the higher number of the zona fasciculata cells and larger size of the zona reticularis cells in male than female gland.
对成年雄性和雌性仓鼠肾上腺皮质的细胞组成进行了评估，并进行了平行的定量超微结构研究。成年雄性仓鼠的肾上腺皮质比雌性含有更多的实质细胞，差异主要取决于球状带和束状带细胞的数量。此外，雄性动物网状带的细胞和细胞核明显更大。对雄性和雌性肾上腺的超微结构观察未发现任何显著差异；然而，体视学显示，雄性仓鼠网状带细胞中线粒体区室和膜空间的体积，以及线粒体嵴和光滑内质网小管的表面积显著更高。每单位重量腺体的肾上腺切片和匀浆产生的皮质醇产量，雄性仓鼠高于雌性。基于这些数据，似乎可以认为，观察到的仓鼠肾上腺皮质醇分泌速率的性别差异，取决于雄性腺体中束状带细胞数量较多以及网状带细胞比雌性腺体中的大。
