| Abstract: | Changes in captopril sensitivity as a result of coronary embolization by 15 um microspheres were studied in rats. Selective coronary embolization was produced by injection of microspheres into the left ventricle during ascending aorta occlusion. The hemodynamic data were examined in conscious rats 21 days after embolization or sham operation before and after captopril bolus injection (1 mg/kg) by using microspheres method. Captopril injection caused a significant increase of the blood flow in the heart, kidneys, skin and some intestinal organs. |
