Figure Lengend Snippet: Time-dependent changes in the mean arterial pressure (MAP) of angiotensin II (Ang II)-salt-induced hypertensive rats. Male Sprague-Dawley rats with radio-telemetry pressure transducers underwent surgery for the subcutaneous implantation of either saline- or Ang II-filled osmotic minipump. They received an intracerebroventricular injection of either phosphate-buffered saline (PBS)- or clodronate-liposomes and were provided with a high-salt diet (2.0% NaCl). The saline-salt treatment groups are represented by a dotted line, with PBS-liposome (open triangle) or clodronate-liposome (open circle). The Ang II-salt treatment groups are represented by a solid line, with PBS-liposome (solid triangle) or clodronate-liposome (solid circle). The numbers in parentheses indicated the number of rats tested; *p < 0.05 versus the rats receiving saline-salt treatment with PBS-liposome or clodronate-liposome; #p < 0.05 versus the rats receiving Ang II-salt treatment with PBS-liposome.
