Fig. 5From: Novel 24-h ovine model of brain death to study the profile of the endothelin axis during cardiopulmonary injuryScatterplot of a big endothelin and b endothelin-1 concentrations vs average hourly vasoactive infusion doses. Filled square = noradrenaline, filled diamond = dopamine. Although these agents may stimulate endothelin release, scatterplots do not indicate a correlation between dose and levels measuredBack to article page
