神经降压素(neurotension,NT)是1973年 Carraway 和 Leeman 首先从牛下丘脑分离出来的一种降压物质,为13个氨基酸组成的直链多肽。日本 Yamanaka 等用微电极及等长张力记录法研究 NT 对离体豚鼠回肠纵行肌及环行肌的电特性及机械特性的作用。结果提示,NT 对豚鼠回肠的纵行肌及环行肌有直接作
Neurotensin (NT) is a kind of antihypertensive substance isolated from the hypothalamus in 1973 by Carraway and Leeman. It is a 13 amino acid linear polypeptide. Yamanaka Japan and other microelectrodes and isobaric tension recording method to study NT on isolated guinea pig ileum longitudinal and circular muscle electrical and mechanical properties. The results suggest that NT directly on guinea pig ileum longitudinal and circular muscles
