The effects of atrial natriuretic peptide (ANP-28), brain natriuretic peptide (BNP-32) and C-type natriuretic peptide (CNP-22) on body temperature were investigated in rats. Intracerebroventricular administration of each peptide in doses of 400 or 1000 ng caused a dose-related elevation in colon temperature 30 and 60 min after injection. A 40 ng dose of ANP-28 was also hyperthermic at 60 min. An intramuscular (i.m.) injection of noraminophenazone (a cyclooxygenase inhibitor) abolished the natriuretic peptide-induced hyperthermia. The results show that natriuretic peptides may participate in thermoregulatory processes in the central nervous system, and that their hyperthermic effect may be mediated via a cyclooxygenase-involved pathway.
研究了心房利钠肽(ANP - 28)、脑利钠肽(BNP - 32)和C型利钠肽(CNP - 22)对大鼠体温的影响。以400或1000 ng的剂量脑室内注射每种肽后,在注射后30和60分钟引起结肠温度呈剂量相关的升高。40 ng剂量的ANP - 28在60分钟时也引起体温升高。肌肉注射氨基比林(一种环氧化酶抑制剂)消除了利钠肽诱导的体温升高。结果表明,利钠肽可能参与中枢神经系统的体温调节过程,并且它们的体温升高作用可能通过涉及环氧化酶的途径介导。
