  • Title: [Effect of opiate receptor agonists on the course of hemorrhagic shock in rats].
    Author: Slepushkin VD, Grässler J, Zoloev GK, Scheuch DV.
    Journal: Biull Eksp Biol Med; 1989 Jun; 107(6):667-9. PubMed ID: 2551413.
    Abstract:
    The experiments have been performed on 93 male rats, weighing 200-250 g. In acute blood loss various arterial pressure (AP) changes have been demonstrated--the marked hypertension is being changed by gradual AP increase. The injection of m-receptors' agonist DAGO prevents systolic and diastolic AP increase, agonist DADL prevents diastolic AP increase in acute momentary blood loss. In gradual blood loss DAGO (more than DADL) slows down both the decrease and the subsequent AP increase in rats. DAGO is determined to decrease, and DADL--to increase the minute blood volume. The mechanisms of opioids' action and their significance in pathogenesis of hemodynamic disturbances in shock are being discussed.
