在成年雌性大鼠下丘脑腹内侧部(VMH)损毁10天后,研究了灌流胰腺的生长抑素、胰岛素和胰升糖素的分泌,并与假手术对照组进行比较,以评估它们对下丘脑的控制作用。无论在基础状态下还是在茶碱和精氨酸+茶碱刺激下,VMH大鼠的胰岛素分泌均显著增加。VMH组大鼠的基础胰高血糖素分泌量更大,对茶碱和精氨酸联合应用时的胰升糖素反应也更强。VMH大鼠基础生长抑素分泌与对照组相似,但VMH大鼠由茶碱和精氨酸+茶碱诱导的生长抑素分泌显着增加。VMH损毁大鼠胰腺组织中生长抑素含量和生长抑素浓度均升高。这些结果表明,在VMH破坏后,A、B和D细胞存在高反应性,并为下丘脑在调节胰腺生长抑素分泌中的作用提供了新的证据。
Somatostatin, insulin, and glucagon secretion by the perfused pancreas were studied in adult female rats 10 days after ventromedial hypothalamic (VMH) lesions and in sham operated controls to assess the role of their hypothalamic control. Insulin secretion was significantly greater in VMH-lesioned rats both under basal conditions and after stimulation by theophylline and arginine plus theophylline. Basal glucagon secretion was greater in VMH-lesioned rats as was the glucagon response to theophylline alone and in combination with arginine. Basal somatostatin secretion was similar in VMH and control rats but somatostatin secretion induced by theophylline and by arginine plus theophylline was significantly increased in VMH-lesioned rats. Both the pancreatic content and concentration of somatostatin were increased in VMH-lesioned rats. These results indicate the presence of hyperresponsiveness of A, B, and D cells following VMH destruction and provide new evidence for a role of the hypothalamus in the regulation of pancreatic somatostatin secretion.
