Abstract

Opioids interact with sympathetic and renin-angiotensin systems in control of mean arterial pressure (MAP). Our earlier finding that biphalin, a synthetic enkephalin analogue, decreased MAP in anaesthetized spontaneously hypertensive rats (SHR) prompted us to further explore this action, to get new insights into pathogenesis of various forms of hypertension. Biphalin effects were studied in SHR, uninephrectomized rats on a high-salt diet (HS/UNX), and rats with angiotensin-induced hypertension (Ang-iH). Besides MAP, renal and iliac blood flows (RBF, IBF) and vascular resistances were measured. In anaesthetized and conscious SHR, biphalin (300 μg·h
