【摘要】 将神经肽Ｙ（ＮＰＹ）（５０ｐｍｏｌ）注入大鼠的杏仁内侧核，观察由此引起的血压和心率的变化。在此变化达到最大值时，用ＨＰＬＣ－ＥＤ法检测外周血中儿茶酚胺的变化。结果表明：ＮＰＹ能显著降低血压，这时外周血中去甲肾上腺素（ＮＥ）明显下降。提示ＮＰＹ在杏仁内侧核引起的心血管效应与外周血中ＮＥ有密切的关系。更多还原

【Abstract】 Changes of cardiovascular effect induced by injection of NPY(50pmol)into medial amygdaloid neucleus were investigated in rats.The contents of catecholamine in peripheral blood were measured by highperformance liquid chromotography with electrochemical detector(HPLC-ED),NPY could cause decompressure effect while the concentration of NE in peripheral blood reduced.These results showed that NPY-induced decompressure effect involved the NE in peripheral blood.更多还原
