Effect of capsule infusion on mean arterial blood pressure. PFD-filled PLGA microcapsules (1.5 µm), 0.25% PVA or 0.9% NaCl were infused for 30 min (light gray, 20 ml/kg body weight × h). The values plotted are mean ± SEM of 14-6 (capsules), 9-3 (PVA and NaCl) individual experiments, *p < 0.05 compared to NaCl group for time-matched data (0–90 min).
