神经降压素(Neurotensin,NT)系1973年由Carraway和Leeman首先从牛的下丘脑中提取到的一种内源性多肽。NT在体内广泛分布于消化道和神经系统,具有多种生物效应。NT的RIA国外已有一些报道,但国内迄今尚未见报告。本工作旨在建立NT灵敏可靠的RIA,为国内开展NT的理论研究和临床应用创造条件。
Neurotensin (NT) was an endogenous polypeptide first extracted from the hypothalamus of cattle in 1973 by Carraway and Leeman. NT is widely distributed in the body in the digestive tract and the nervous system, with a variety of biological effects. NT RIA has some reports abroad, but so far no report has been reported in China. This work aims to establish NT sensitive and reliable RIA, to create conditions for the theoretical research and clinical application of NT.
