METHODS: Pretreatment of       cultured endothelial cells from human umbilical veins (HUVECs) with different       concentrations of the non-selective beta-blocker propranolol, the beta 1-blocker        metoprolol and the beta 1-blocker and beta 2-agonist celiprolol (all       10(-7)-10(-4) mol L-1) was found to reduce ET-1 production.
