Interrelation between the hypothalamic nuclei and pancreatic endocrine fraction has been studied in mice of C57BL/KsJ line which were hetero- and homozygotic by diabetic gene db. The immunocytochemical method was used to determine content of insulin, glucagon and somatostatine in the Langerhans islet cells and morphohistochemical methods were used to estimate the state of hypothalamic structures. It has been shown that regulation of the pancreatic endocrine function and metabolic processes in which it participates by the hypothalamus may be provided at least by two mechanisms: neurohormonal one, connected with hormone secretion from paraventricular and supraoptic nuclei, and neuroconductory mechanism, connected with the ventromedial nucleus and lateral hypothalamic region.
在C57BL/KsJ品系的小鼠中研究了下丘脑核与胰腺内分泌部分之间的相互关系,这些小鼠携带糖尿病基因db的杂合子和纯合子。采用免疫细胞化学方法测定胰岛细胞中胰岛素、胰高血糖素和生长抑素的含量,并采用形态组织化学方法评估下丘脑结构的状态。结果表明,下丘脑对胰腺内分泌功能及其参与的代谢过程的调节至少可通过两种机制实现:一种是神经激素机制,与室旁核和视上核的激素分泌有关;另一种是神经传导机制,与腹内侧核和下丘脑外侧区有关。
