生长抑素的生理学生长抑素是14个氨基酸组成的环状多肽,起初认为它是下丘脑中的一种生长激素(GH)释放抑制激素,现认为生长抑素广泛分布于各种细胞,且与GH分泌的调节无关。它在中枢神经系统、外分泌和内分泌胰腺以及胃肠道中的含量均很高。因其存在广泛,故认为它在多种分泌过程中起一种生理调节作用,它除了抑制GH释放外,还抑制胰腺和胃肠道激素的分泌,并抑制胰腺外分泌和胃液分泌。
The somatostatin physiology student long-actin is a 14-amino-acid cyclic polypeptide that was originally thought to be a growth hormone (GH) release-inhibitory hormone in the hypothalamus. It is now believed that somatostatin is widely distributed in various cells, and It is not related to the regulation of GH secretion. It is high in the central nervous system, exocrine and endocrine pancreas, and in the gastrointestinal tract. Because of its extensive existence, it is thought that it plays a physiological regulatory role in a variety of secretory processes. In addition to its inhibition of GH release, it also inhibits the secretion of hormones in the pancreas and gastrointestinal tract, and inhibits exocrine pancreatic and gastric secretion.
