Long-term normalization of blood pressure in SHR and 1-kidney 1-clip rats by synthetic precursor of stable PAF analogue without systemic effects in normotensive rats  Sergei I. Malekin, Sergei V.

3 Fig. 2 Time-dependence of the action of intravenous HAG administration (1mg/kg) on mean arterial pressure (MAP, A) and heart rate (HR, B) in SHR. During the first 60min, MAP and HR were measured at each 5-min interval and then at 24h of HAG administration. HAG or vehicle (liposomal suspension) was injected at time point zero. Means±SE obtained for 8 control and 9 HAG-treated rats are shown at time intervals corresponding to the end of each measurement.

4 Fig. 3 Time-dependent changes of MAP (ΔMAP, A) and heart rate (ΔHR, B) in 1K1C rats subjected to intravenous administration of HAG (1mg/kg). Three rats with initial MAP of 150–205mmHg were selected for this experiment. MAP and HR were measured for 90min after drug delivery at 5-min intervals. Means±SE are shown.

5 Fig. 4 Correlation between baseline MAP and its decline caused by HAG (ΔMAP) in 1K1C rats. MAP was measured before and within 90min of intravenous 1mg/kg HAG injection. Pathophysiology  , DOI: ( /j.pathophys ) Copyright © 2010 Elsevier Ireland Ltd Terms and Conditions

6 Fig. 5 Effect of 2-week per os feeding with HAG on SBP in 1K1C rats. Rats with SBP>140mmHg were selected for this study. HAG (5mg/kg) or vehicle (olive oil) was administered chronically per os every 48h for 2 weeks. SBP was measured within 8h after each injection. Means±SE are shown.
