一、心房肽的作用机理心房肽(ANP)不仅产生于心房肌细胞(右房比左房高,从心外膜到心内膜依次递减,房间隔最少),还存在于大鼠下丘脑的室周核、脑的终板脉络组织、弓状核和腹侧乳头前核及脑桥的背内侧顶盖核,还存在于肾、肺,以右肺为最高。肺产生的ANP也具有利钠利 First, the mechanism of atrial natriuretic peptide Atrial natriuretic peptide (ANP) is not only produced in atrial myocytes (right atrium than the left atrium high, from the epicardial to the endocardial in turn decreasing, atrial septum at least), but also in rat hypothalamus Ventricular perinuclear, cerebral endplate venous tissues, arcuate nucleus and ventral preputial nucleus and dorsal medullary nucleus of the pons, but also in the kidney, lung, with the right lung as the highest. ANP produced by the lung also has nesiritide
