胆囊收缩素作用的研究进展

胆囊收缩素是一种广泛存在于胃肠道和中枢神经系统的脑肠肽，具有多种生理学功能。除了促进胆囊收缩以外，还可以调节胰酶的分泌和胰腺的生长、胃肠蠕动，抑制胃酸分泌，并参与饱腹信号的传导。此外，胆囊收缩素也是中枢和肠道神经系统的一种递质，并且是脑中含量最丰富的一种神经肽，本文介绍了胆囊收缩素的多种生物学功能及其在糖尿病中的作用。

Progress on the Function of Cholecystokinin

Cholecystokiniu is a peptide, which distributed widely throughout the gastrointestinal tract and the central nervous system, and has a number of physiological effects. In addition to gallbladder contraction, cholecystokinin also regulates enzyme secretion and growth of pancreas, intestinal motility, satiety signalling and the inhibition of gastric acid secretion. Cholecystokinin is a transmitter in central and intestinal neurons and is also the most abundant neuropeptide. In this paper, the function of Cholecystokinin was reviewed.
