1. Endothelin, a novel vasoconstrictor 21-residue peptide isolated from the supernatant of cultured porcine endothelial cells, has been shown to be increased in plasma in a variety of cardiovascular disease states, including acute myocardial infarction, acute renal failure and essential hypertension. We determined the time course of plasma and pulmonary lymph endothelin-like immunoreactivity in relation to the progressive deterioration of cardiopulmonary function in an ovine septic shock model leading to multi-organ failure syndrome and death within 42 h of a continuous intravenous infusion of Escherichia coli endotoxin (40 ng min-1kg-1). 2. Plasma and pulmonary lymph endothelin-like immunoreactivity were measured by r.i.a. using a specific antiserum raised in rabbits against porcine endothelin-1. Endothelin-like immunoreactivity was further determined in lung tissue and the thoracic duct lymph of endotoxin-treated sheep by reversed-phase h.p.l.c. In control instrumented conscious sheep not infused with endotoxin, there were no significant changes in any of the measured cardiopulmonary and biochemical variables, with plasma and pulmonary lymph endothelin-like immunoreactivity remaining below the detection limit (less than 1 pg/tube) throughout the 72 h study period. 3. Conscious sheep receiving endotoxin showed a major hypotensive septic syndrome, including persistently decreased systemic blood pressure, systemic vascular resistance, stroke volume, left ventricular stroke work, associated with sustained pulmonary vasoconstriction and protein-rich pulmonary oedema (greater than five-fold increase in pulmonary lymph flow and protein clearance), and marked lactic acidosis, leading to the death of animals within 14-42 h despite institution of mechanical ventilation and adequate intravascular volume replacement.(ABSTRACT TRUNCATED AT 250 WORDS)
