We analyzed the influence of endothelin-1 and endocardial endothelium on the myocardial effects of angiotensin-II. Angiotensin-II (10(-9)-10(-5) M) was tested in rabbit right papillary muscles in absence (Protocol-A) or presence of PD-145065 (10(-7) M; Protocol-B), BQ-123 (10(-7) M; Protocol-C) or
Expression and pharmacological properties of endothelin receptors (ETRs) were investigated in H9c2 cardiomyoblasts. The mechanism of receptor-mediated modulation of intracellular Ca(2+) concentration ([Ca(2+)](i)) was examined by measuring fluorescence increase of Fluo-3-loaded cells with flow cytometry. Binding assays showed that [125I]endothelin-1
Endothelin peptides are polykines with strong vasoconstrictor properties. We have previously shown that endothelin antagonism (PD145065) reduces the local severity of acute pancreatitis. We now investigated the effect of endothelin antagonism on systemic inflammation in a model of acute hemorrhagic
