摘　　要：本文观察了麻醉大鼠外侧隔核(LS)内微量注射神经肽Y(NPY)引起的心血管效应。LS内微量注射NPY可使血压和心率明显增加,其加压反应呈量效关系,但心率加快反应则否。LS内微量注射生理盐水对血压和心率无明显影响。Cardiovascular effects of microinjection of neuropeptide Y (NPY) into thelateral septal nucleus (LS) were investigated in anaesthetized rats. The micro-injection gave rise to a significant increase in blood pressure and heart rate. Thepressure response was dose-dependent but the tachycardia was not. Control injec-tion of 0.9% saline into LS produced no haemodynamic response.
