Hemodynamic interactions of verapamil and isoflurane.

abstract：BACKGROUND:Melanocortin peptides improve hemodynamic parameters and prevent death during severe hemorrhagic shock. In the present research we determined influences of a synthetic melanocortin 1/4 receptor agonist on the molecular changes that occur in rat liver during hemorrhage. METHODS:Controlled-volume hemorrhage w...
