In the present study the authors focused their attention on the studies of PAS positive mucopolisaccharides in the hypothalamus and ependyma of the third ventricle and on the observation of changes in the volume of cell nuclei of neurons--nucl. supraopticus (NSO), nucl. hypothalamicus ventromedialis (NVM) and nucl. tuberomammillaris (NTM) in sheep after irradiation with 2.46 Gy and hormone stimulation during anestrous. Ageline sponges and serum gonadotropins were used for estrous synchronization and hormone stimulation, respectively. The increased amount of PAS positive substances found in the examined hypothalamic nuclei after irradiation and hormone treatment seem to stimulate the function of the hypothalamic structures. The results of caryometric analysis in spring sheep also confirm this view. Administration of hormones in combination with irradiation results in increased number of ependyma cells and desquamation of the surface layers.
在本研究中，作者将注意力集中于第三脑室下丘脑和室管膜中PAS阳性粘多糖的研究，以及对绵羊在接受2.46 Gy照射及乏情期激素刺激后，视上核（NSO）、下丘脑腹内侧核（NVM）和乳头体核（NTM）神经元细胞核体积变化的观察。分别使用阿吉林海绵和血清促性腺激素进行发情同步和激素刺激。照射和激素处理后，在所检查的下丘脑核中发现的PAS阳性物质数量增加，似乎刺激了下丘脑结构的功能。春季绵羊的细胞核测量分析结果也证实了这一观点。激素与照射联合使用导致室管膜细胞数量增加和表层脱屑。
